Having trouble paying your bills? Constantly making mini- mum payments each month? Don’t know how much you owe? Worried about getting a bad credit report? According to Index- CreditCards.com, the average U.S. household has credit card debt of over $7,300, with interest rates ranging from the mid- dle to high teens. Credit card companies have made running up that balance deceptively easy.

However, there are a number of steps you can take to pay off the debt and get back on track. Of course, this will require you to adjust your spending habits and become more careful about your spending.

1. Determine what you owe. Make a list of all the debts you have including the name of the creditor, your total balance, your minimum monthly payment, and your interest rate. This will help you determine in which order you should pay down your debts.

2. Pay it down. Work overtime or take on a second job and devote that income to paying down debt. Cash in CDs, pay down home equity loans, and pay down loans against retire- ment. Have a garage sale. Do whatever you can to earn extra money and devote that money to paying down your debt.

3. Reduce expenses. Eliminate any unnecessary expenses such as eating out and expensive entertainment. Clip coupons, shop at sales, and avoid impulse purchases. Brown bag it at work and be creative about gifts. Above all, stop using credit cards. Just giving up that expensive cup of coffee each morning can save you more than $750 dollars a year.

4. Record your spending. This is actually your key to getting out of debt. You’re in debt because you spent money you didn’t have. Avoiding more debt starts with knowing what you are spending your money on. Each day for at least one month, write down every amount you spend, no matter how small. Reviewing how you spend your money allows you to set priorities.

5. Make a budget based on your spending record. Write down the amount you spent in each category of spending last month as you budget for spending for the next month. Categorize your monthly expenses into logical groups such as necessities (food, rent, medicine, pet food, and so on), should have (things you need but not immediately, such as new workout gear), and like to have (things you don’t need but enjoy (magazines, cable television). One expense should be paying off your debt. Did you know that making a minimum payment of $26 on a single credit card with a $1,000 balance and 19% interest will take more than five years to pay off?

6. Pay cash. This results in a significant savings in terms of what you purchase and not having to pay interest on those purchases. When you don’t have the cash, you don’t buy.

7. Resolve to spend less than you make. Realize once and for all that if you can’t pay for it today then you can’t afford it.

Managing your credit and knowing exactly how much you are paying for using credit are important concepts that you will learn in this chapter.

426 CHAPTER 12

Many individuals and businesses make purchases for which they do not pay the full amount at the time of purchase. These purchases are paid for by paying a portion of the amount owed in regular payments until the loan is completely paid. This type of loan or credit is often referred to as consumer credit.

In the preceding chapters we discussed the interest to be paid on loans that are paid in full on the date of maturity of the loan. Many times, loans are made so that the maker (the borrower) pays a given amount in regular payments. Loans with regular payments are called installment loans.

There are two kinds of installment loans. Closed-end credit is a type of loan in which the amount borrowed plus interest is repaid in a specified number of equal payments. Examples in- clude bank loans and loans for large purchases such as cars and appliances. Open-end credit is a type of loan in which there is no fixed number of payments—the person keeps making pay- ments until the amount is paid off, and the interest is computed on the unpaid balance at the end of each payment period. Credit card accounts, retail store accounts, and line-of-credit accounts are types of open-end credit.

Consumer credit: a type of credit or loan that is available to individuals or businesses. The loan is repaid in regular payments.

Installment loan: a loan that is repaid in regular payments.

Closed-end credit: a type of installment loan in which the amount borrowed and the interest are repaid in a specified number of equal payments.

Open-end credit: a type of installment loan in which there is no fixed amount borrowed or fixed number of payments. Payments are made until the loan is paid off.

12-1 INSTALLMENT LOANS AND CLOSED-END CREDIT LEARNING OUTCOMES 1 Find the amount financed, the installment price, and the finance charge of an

installment loan. 2 Find the installment payment of an installment loan. 3 Find the estimated annual percentage rate (APR) using a table.

Should you or your business take out an installment loan? That depends on the interest you will pay and how it is computed. The interest associated with an installment loan is part of the charges referred to as finance charges or carrying charges. In addition to accrued interest charges, installment loans often include charges for insurance, credit-report fees, or loan fees. Under the truth-in-lending law, all of these charges must be disclosed in writing to the consumer.

1 Find the amount financed, the installment price, and the finance charge of an installment loan.

The cash price is the price you pay if you pay all at once at the time of the purchase. If you pay on an installment basis instead, the down payment is a partial payment of the cash price at the time of the purchase. The amount financed is the cash price minus the down payment. The installment payment is the amount you pay each period, including interest, to pay off the loan. The installment price is the total paid, including all of the installment payments, the finance charges, and the down payment.

Finance charges or carrying charges: the interest and any fee associated with an installment loan.

Cash price: the price if all charges are paid at once at the time of the purchase.

Down payment: a partial payment that is paid at the time of the purchase.

Amount financed: the cash price minus the down payment.

Installment payment: the amount that is paid (including interest) in each regular payment.

Installment price: the total amount paid for a purchase, including all payments, the finance charges, and the down payment.

HOW TO Find the amount financed and the installment price 1. Find the amount financed: Subtract the down payment from the cash price.

2. Find the installment price: Add the down payment to the total of the installment payments.

Installment price = total of installment payments + down payment

Amount financed = cash price - down payment

EXAMPLE 1 The 7th Inning purchased a mat cutter for the framing department on the installment plan with a $600 down payment and 12 payments of $145.58. Find the install- ment price of the mat cutter.

= $1,746.96 $145.58*12 =

The installment price is $2,346.96.

= $2,346.96 = $1,746.96 + $600

Installment price = total of installment payments + down payment

HOW TO Find the finance charge of an installment loan 1. Determine the cash price of the item. 2. Find the installment price of the item. 3. Subtract the result found in step 2 from the result of step 1.

Finance charge � installment price � cash price

EXAMPLE 2 If the cash price of the mat cutter in Example 1 was $2,200, find the finance charge and the amount financed.

The finance charge is $146.96 and the amount financed is $1,600.

= $1,600 = $2,200 - $600

Amount financed = cash price - down payment.

= $146.96 Down payment = $600 = $2,346.96 - $2,200.00 Cash price = $2,200.00 Finance charge = installment price - cash price Installment price = $2,346.96

2 Find the installment payment of an installment loan.

Since the installment price is the total of the installment payments plus the down payment, we can find the installment payment if we know the installment price, the down payment, and the number of payments.

HOW TO Find the installment payment, given the installment price, the downpayment, and the number of payments

1. Find the total of the installment payments: Subtract the down payment from the installment price.

2. Divide the total of the installment payments by the number of installment payments.

Installment payment = total of installment payments

number of payments

Total of installment payments = installment price - down payment

428 CHAPTER 12

3 Find the estimated annual percentage rate (APR) using a table.

In 1969 the federal government passed the Consumer Credit Protection Act, Regulation Z, also known as the Truth-in-Lending Act. Several amendments have been made to this original legis- lation. It requires that a lending institution tell the borrower, in writing, what the actual annual rate of interest is as it applies to the balance due on the loan each period. This interest rate tells the borrower the true cost of the loan.

If you borrowed $1,500 for a year and paid an interest charge of $165, you would be paying an interest rate of 11% annually on the entire $1,500 But if you paid the money back in 12 monthly installments of $138.75

you would not have the use of the $1,500 for a full year. Instead, you would be paying it back in 12 payments of $138.75 each. Thus, you are losing the use of some of the money every month but are still paying interest at the rate of 11% of the entire amount. This means that you are actually paying more than 11% interest. The equivalent rate is the annual percentage rate (APR). Applied to installment loans, the APR is the annual simple interest rate equivalent that is actually being paid on the unpaid balances. The APR can be determined using a government-is- sued table.

The federal government issues annual percentage rate tables, which are used to find APR rates (within which is the federal standard). A portion of one of these tables, based on the number of monthly payments, is shown in Table 12-1.

(165 , $1,500 = 0.11 = 11%).

EXAMPLE 3 The installment price of a drafting table was $1,627 for a 12-month loan. If a $175 down payment had been made, find the installment payment.

The installment payment is $121.

= $1,452

12 = $121 Divide.

Installment payment = total of installment payments

number of payments

= $1,627 - $175 = $1,452 Subtract. Total of installment payments = installment price - down paymentProtect Your Credit Rating

Your credit reputation is just as important as your personal reputa- tion. Three different agencies track credit records. They are Equifax, Experian, and TransUnion. You are entitled to a free annual credit report from each of these three nationwide consumer reporting agencies.

STOP AND CHECK 2. The installment price of a piano is $8,997.40 and a down

payment of $1,000 is made. What is the monthly installment payment if the piano is financed for 36 months?

1. The installment price of a refrigerator is $2,087 for a 24-month loan. If a down payment of $150 had been made, what is the installment payment?

3. The installment price of a tire machine is $2,795.28. A down payment of $600 is made. What is the installment payment if the machine is financed for 36 months?

4. Find the installment payment for a trailer if its installment price is $3,296.96 over 30 months and an $800 down payment is made.

HOW TO Find the estimated annual percentage rate using a per $100 of amount financed table 1. Find the interest per $100 of amount financed: Divide the finance charge including interest

by the amount financed and multiply by $100.

2. Find the row corresponding to the number of monthly payments. Move across the row to find the number closest to the value from step 1. Read up the column to find the annual percentage rate for that column. If the result in step 1 is exactly halfway between two table values, a rate halfway between the two rates can be used.

Interest per $100 = finance charge

amount financed * $100

Annual percentage rate (APR): the equivalent rate of an installment loan that is equivalent to an annual simple interest rate.

Interest per $100 = finance charge

amount financed * $100 =

$408

$3,000 ($100) = $13.60

Amount financed = $3,500 - $500 = $3,000 Finance charge = $3,908 - $3,500 = $408

Installment price = 24($142) + $500 = $3,408 + $500 = $3,908

TIP Finding the Closest Table Value

Another way to find the closest table value to the interest per $100 is to compare the interest to the amount halfway between two table values. The halfway amount is the average of the two table values.

In the previous example, $13.60 is between $13.54 and $13.82.

Because $13.60 is less than the halfway amount ($13.68), it is closer to the lower table value ($13.54).

= $13.68

Halfway = $13.54 + $13.82

12-2 PAYING A LOAN BEFORE IT IS DUE: THE RULE OF 78 LEARNING OUTCOME 1 Find the interest refund using the rule of 78.

If a closed-end installment loan is paid entirely before the last payment is actually due, is part of the interest refundable? In most cases it is, but not always at the rate you might hope. If you paid a 12-month loan in 6 months, you might expect a refund of half the total interest. However, this

Rule of 78: method for determining the amount of refund of the finance charge for an installment loan that is paid before it is due.

Refund fraction: the fractional part of the total interest that is refunded when a loan is paid early using the rule of 78.

of the loan. The interest for the second payment is based on of the amount financed because 112 11 12

12 12 of this amount has already been paid. The interest for the third payment is of the amount1012 financed, and so on. The interest on the last payment is based on of the amount financed.

The sum of all the parts accruing interest for a 12-month loan is or 78.

Thus, 78 equal parts accrue interest. The interest each part accrues is the same because the rate is the same and the parts are the same (each is of the principal). Because 78 equal parts112

7 + 6 + 5 + 4 + 3 + 2 + 1, 12 + 11 + 10 + 9 + 8 +

1 12

each accrue equal interest, the interest each part accrues must be of the total interest for the one-year loan. So if the loan is paid in full with three months remaining, then the interest that would have accrued in the 10th, 11th, and 12th months is refunded. In the 10th month, three parts each accrue of the total interest; in the 11th month, two parts each accrue of the total inter-178

1 78

1 78

est; and in the 12th month, one part accrues of the total interest. So each of the 3 + 2 + 1178 parts, or 6 parts, accrues of the total interest. Thus of the total interest is refunded. The frac-678

1 78

tion is called the refund fraction. Not all installment loans are for 12 months, but the rule of 78 gives us a pattern that we can

apply to loans of any allowable length.

HOW TO Find the refund fraction for the interest refund 1. The numerator is the sum of the digits from 1 through the number of months remaining of a

loan paid off before it was due. 2. The denominator is the sum of the digits from 1 through the original number of months of

the loan. 3. The original fraction, the reduced fraction, or the decimal equivalent of the fraction can be used.

The sum-of-digits table in Table 12-2 can be used to find the numerator and denominator of the refund fraction.

is not the case because the portion of the monthly payment that is interest is not the same from month to month. In some cases, interest or finance charge refunds are made according to the rule of 78. Some states allow this method to be used for short-term loans, generally 60 months or less. Laws and court rulings protect and inform the consumer in matters involving interest.

1 Find the interest refund using the rule of 78.

The rule of 78 is not based on the actual unpaid balance after a payment is made. Instead, it is an approximation that assumes the amount financed (which includes the interest) of a one-year loan is paid in 12 equal parts. For the first payment, the interest is based on the total amount financed, or

There is a shortcut for finding the sum of consecutive numbers beginning with 1. You may be interested to know that a young boy in elementary school discovered this shortcut in the late 18th century. He later went on to be one of the greatest mathematicians of all time. His name was Carl Friedrich Gauss (1777–1855).

TIP The Sum of Consecutive Numbers Beginning with 1

Multiply the largest number by 1 more than the largest number and divide the product by 2.

Sum of consecutive numbers from 1 through 12 = 12(13)

TIP Continuous Sequence of Steps Using a Calculator

It is advisable in making calculations as in Example 2 that you use a continuous sequence of steps in a calculator. It is time-consuming and more mistakes are made if you reenter the result of a previous calculation to make another calculation.

For Example 2, the continuous sequence of steps is:

When using a calculator, there is no need to reduce fractions first.

12-3 OPEN-END CREDIT LEARNING OUTCOMES 1. Find the finance charge and new balance using the average daily balance method. 2. Find the finance charge and new balance using the unpaid or previous month’s balance.

Open-end loans are often called line-of-credit accounts. While a person or company is paying off loans, that person or company may also be adding to the total loan account by making a new purchase or otherwise borrowing money on the account.

For example, you may want to use your Visa card to buy new textbooks even though you still owe for clothes bought last winter. Likewise, a business may use an open-end credit account to buy a new machine this month even though it still owes the bank for funds used to pay a major supplier six months ago.

Nearly all open-end accounts are billed monthly. Interest rates are most often stated as an- nual rates. The Fair Credit and Charge Card Disclosure Act of 1988 and updates passed since that time specify the required details that must be disclosed for charge cards and line-of-credit accounts. These details include all fees, grace period, how finance charges are calculated, how late fees are assessed, and so on. While this act addresses the disclosure of fees and charges, The Credit Card Act of 2009 (effective February 22, 2010) imposes regulations on credit card issuers in an attempt to stop them from unfairly taking advantage of consumers.

1 Find the finance charge and new balance using the average daily balance method.

Many lenders determine the finance charge using the average daily balance method. In this method, the daily balances of the account are determined, and then the sum of these balances is divided by the number of days in the billing cycle. This average daily balance is next multiplied by the monthly interest rate to find the finance charge for the month.

Even though open-end credit accounts are billed monthly, the monthly period may not coin- cide with the first and last days of a calendar month. To spread out the workload for the billing department, each account is given a monthly billing cycle. The billing cycle is the days that are included on a statement or bill. This cycle can start on any day of a month. For example, a billing cycle may start on the 22nd of one month and end on the 21st of the next month. This means that the number of days of a billing cycle will vary from month to month based on the number of days in the months involved.

Line-of-credit accounts: a type of open-end loan.

Average daily balance: the average of the daily balances for each day of the billing cycle.

Billing cycle: the days that are included on a statement or bill.

HOW TO Find the average daily balance 1. Find the daily unpaid balance for each day in the billing cycle.

(a) Find the total purchases and cash advances charged to the account during the day. (b) Find the total credits (payments and adjustments) credited to the account during the day. (c) To the previous daily unpaid balance, add the total purchases and cash advances for the

day (from step 1a). Then subtract the total credits for the day (from step 1b).

2. Add the unpaid balances from step 1 for each day of the billing cycle, and divide the sum by the number of days in the cycle.

Average daily balance = sum of daily unpaid balances

number of days in billing cycle

Daily unpaid balance = previous daily unpaid balance + total purchases and cash advances for the day - total credits for the day

HOW TO Find the finance charge using the average daily balance 1. Determine the decimal equivalent of the rate per period. 2. Multiply the average daily balance by the decimal equivalent of the rate per period.

EXAMPLE 1 Use the chart showing May activity in the Hodge’s Tax Service charge account to determine the average daily balance and finance charge for the month. The bank’s finance charge is 1.5% per month on the average daily balance.

Date transaction posted Transaction Transaction amount May 1 Billing date Balance $122.70 May 7 Payment 25.00 May 10 Purchase (pencils) 12.00 May 13 Purchase (envelopes) 20.00 May 20 Cash advance 50.00 May 23 Purchase (business forms) 100.00

To find the average daily balance, we must find the unpaid balance for each day, add these bal- ances, and divide by the number of days.

Day Balance 1 122.70 2 122.70 3 122.70 4 122.70 5 122.70 6 122.70 7 97.70 8 97.70 9 97.70

(179.70 + 100)

The average daily balance can also be determined by grouping days that have the same balance. For the first six days, May 1–May 6, there is no activity, so the daily unpaid balance is the pre-

vious unpaid balance of $122.70. The sum of daily unpaid balances for these six days, then, is

On May 7 there is a payment of $25, which reduces the daily unpaid balance.

The new balance of $97.70 holds for the three days (May 7, 8, and 9) until May 10.

$97.70(3) = $293.10

$122.70 - $25 = $97.70

$122.70(6) = $736.20

122.70(6).

Total: $5,322.70 Average Daily Balance: $171.70

When Does the Balance Change?

In most cases, if a transaction reaches a financial institution at any time during the day, the transaction is posted and the balance is updated at the end of the business day. Thus, the new balance takes effect at the beginning of the next day. Calculations on the day’s unpaid balance are made on the end-of- day amount (same as beginning of next day).

Divide the sum of $5,322.70 by the 31 days.

To find the interest, multiply the average daily balance by the monthly interest rate of 1.5%.

The average daily balance is $171.70 and the finance charge is $2.58.

= $2.58 Finance charge = $171.70(0.015)

= $5,322.70

2 Find the finance charge and new balance using the unpaid or previous month’s balance.

Not all open-end credit accounts use the average daily balance method for determining the monthly finance charge. Another method uses the unpaid or previous month’s balance as the basis for determining the finance charge. In this method, the new purchases or payments made during a month do not affect the finance charge for that month.

Use the statement in Figure 12-1 for Exercises 1–4.

1. Make a table showing the unpaid balance for each day in the billing period.

2. Find the average daily balance for the month.

3. Find the finance charge for the month. 4. Find the new balance for the month.

HOW TO Find the finance charge and new balance using the unpaid orprevious month’s balance Finance charge:

1. Find the monthly rate.

2. Multiply the unpaid or previous month’s balance by the monthly rate.

New balance:

1. Total the purchases and cash advances for the billing cycle. 2. Total the payments and credits for the billing cycle. 3. Adjust the unpaid balance of the previous month using the totals in steps 1 and 2.

New balance � Previous balance � Finance charge � Purchases and cash advances � Payments and credits

Finance charge = Unpaid balance * Monthly rate

Monthly rate = Annual percentage rate

During the billing cycle she purchased shoes for $62.58 and a handbag for $35.18. She returned a blouse that she had purchased in the previous billing cycle, received a credit of $22.79, and she made a payment of $75. If the store uses the unpaid balance method, what are the finance charge and the new balance?IS

1 Find the amount financed, the installment price, and the finance charge of an installment loan. (p. 426)

SUMMARY CHAPTER 12

What to Remember with Examples

1. Find the amount financed: Subtract the down payment from the cash price.

2. Find the installment price: Add the down payment to the total of the installment payments.

Installment price = total of installment payments + down payment

Amount financed = cash price - down payment

Find the installment price of a computer that is paid for in 24 monthly payments of $113 if a down payment of $50 is made.

(24)($113) + $50 = $2,712 + $50 = $2,762

Find the finance charge of an installment loan:

Subtract the cash price from the installment price.

Finance charge = installment price - cash price

If the cash price of the computer in the previous example was $2,499, how much is the finance charge?

$2,762 - $2,499 = $263

2 Find the installment payment ofan installment loan. (p. 427) 1. Find the total of the installment payments: Subtract the down payment from the installmentprice.

2. Divide the total of installment payments by the number of installment payments.

Installment payment = total of installment payments

number of payments

Total of installment payments = installment price - down payment

Find the monthly payment on a computer if the cash price is $3,285. A 14% interest rate is charged on the cash price, and there are 12 monthly payments.

A computer has an installment price of $2,187.25 when financed over 18 months. If a $100 down payment is made, find the monthly payment.

Monthly payment = $2,087.25

18 = $115.96

$2,187.25 - $100 = $2,087.25

Monthly payment = $3,744.90

12 = $312.08

Installment price = $3,285 + $459.90 = $3,744.90 $3,285(0.14)(1) = $459.90

3 Find the estimated annual percentage rate (APR) using a table. (p. 428)

CRITICAL THINKING CHAPTER 12

1. Explain the mistake in the solution of the problem and correct the solution.

Dawn Mayhall financed a car and the loan of 42 months required $3,827 interest. She paid the loan off after making 20 payments. How much interest should be refunded if the rule of 78 is used?

Solution:

Thus, $890 should be refunded.

210

903 ($3,827) = $890

Refund fraction = 210

903

2. Explain the mistake in the solution and correct the solution. Ava Landry agreed to pay $2,847 interest for a 36-month loan to

redecorate her greeting card shop. However, business was better than expected and she repaid the loan with 16 months remaining. If the rule of 78 was used, how much interest should she get back?

Solution:

Thus, $1,265.33 should be refunded.

16

36 ($2,847) = $1,265.33

3. Arrange the consecutive numbers from 1 to 10 in ascending order, then in descending order, so that 1 and 10, 2 and 9, 3 and 8, and so on, align vertically. Add vertically. Find the grand total. Finally divide the grand total by 2. Compare the result to the sum of digits 1 through 10.

10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10

4. Explain why finding the sum of consecutive numbers by using the process in Exercise 3 requires that the product be divided by 2.

5. Explain why the formula for finding the sum of consecutive numbers requires the product of the largest number and one more than the largest number rather than one less than the largest number.

6. Give three examples of finding the sum of consecutive odd numbers beginning with 1.

Challenge Problem It pays to read the details! Bank One Delaware offers a Platinum Visa Credit Card to qualifying persons with an introductory 0% fixed APR on all purchases and balance transfers and, after the 12-month introductory period, a low variable APR on purchases and balance transfers at a current annual rate of 8.99%. However, the default rate is 24.99% APR. A default occurs if the minimum payment is not received by the due date on the billing statement or if your bal- ance ever exceeds your credit limit. Find the difference in just one month’s interest on an average daily balance of $1,000 if the payment is not received by the due date.

CASE STUDIES

12-1 Know What You Owe Nancy Tai has recently opened a revolving charge account with MasterCard. Her credit limit is $1,000, but she has not charged that much since opening the account. Nancy hasn’t had the time to review her monthly statements promptly as she should, but over the upcoming weekend she plans to catch up on her work. She has been putting it off because she can’t tell how much interest she paid or the unpaid balance in November. She spilled watercolor paint on that portion of the statement.

In reviewing November’s statement she notices that her beginning balance was $600 and that she made a $200 payment on November 10. She also charged purchases of $80 on November 5, $100 on November 15, and $50 on November 30. She paid $5.27 in interest the month before. She does remember, though, seeing the letters APR and the number 16%. Also, the back of her statement indicates that interest was charged using the average daily balance method, including current purchases, which considers the day of a charge or credit.

1. Find the unpaid balance on November 30 before the interest is charged.

2. Assuming a 30-day period in November find the average daily balance.

3. Calculate the interest for November.

4. What was the unpaid balance for November after interest is charged?

12-2 Massage Therapy It was time to expand her massage therapy business, and Arminte had finally found a commercial space that met her needs. With room for herself and the two new massage therapists she planned to hire, and adjacent to a chiropractor’s office, the space was everything that she had hoped for. Now all she needed was to finalize purchases for three massage rooms, furniture for the reception area, various artwork, and miscellaneous supplies. Arminte started to make a list of massage equipment: 3 tables at $1,695 each; 3 stools at $189 each; a portable massage chair for $399; and the list went on—bolsters, pillows, sheets, table warmers, and music. By the time Arminte was finished, her massage equipment alone totaled $7,644.25, including sales tax. The supplier offered in-house financing of 24 monthly payments at $325.33 per month, with a 10% down payment.

1. Find the amount financed, installment price, and the finance charge presuming Arminte goes with the financing available through her supplier.

2. Use Table 12-1 to find the annual percentage rate (APR) of the financing.
