1. Profit margin = Net income / Revenue
1. Gross margin % = Gross margin $ / Revenue
1. Operating expense % = Operating expense / Revenue
1. Operating income % = Operating income / Revenue
1. Tax rate = Tax expense / Profit before tax
1. Current ratio = Current assets / Current liabilities
1. Quick ratio = (Current assets – inventory) / Current liabilities
1. Days receivable = Total Receivables / (Revenue / # days in the period)
1. Days inventory = Total inventory / (Cost of sales / # days in the period)
1. Days payables = Total accounts payable / (Cost of sales / # days in the period)
1. Cash conversion cycle = Days receivable + Days inventory – Days payable
1. A day of receivables working capital is worth = Revenue / # days in a period
1. A day of inventory working capital is worth = Cost of sales / # days in a period
1. A day of payables working capital is worth = Cost of sales / # days in a period
1. Debt ratio = Total liabilities / Total assets
1. Debt to equity ratio = Total debt / Total equity
(Debt defined as interest bearing liabilities. Debt normally includes bank debt, commercial paper, notes payable and capital leases)
1. Times interest earned = Earnings before interest and tax / Interest expense
(Earnings before interest and tax is commonly referred to as EBIT)
1. Return on Assets = Net income / Total assets
1. Return on Equity = Net income / Common equity
1. DuPont Formula = (Net income/Revenue) X (Revenue/Assets) X (Assets/Equity)
= Return on equity
1. Free cash flow;
1. Economic Value Added (EVA):
=NOPAT – Capital charge
Where capital charge = (WACC) X Operating capital
1. Price/earnings multiple = Share price / Earnings per share
1. Market capitalization = Share price X # diluted shares outstanding
1. Cost of debt = (interest rate ) X (1 – tax rate)
1. Cost of equity = = Risk free rate + beta (market risk premium)
(for this class we will normally use a market risk premium of 6.5)
1. Weighted Average Cost of Capital (WACC)
WACC = + % Debt X After tax cost of debt
+ % Preferred X Cost of preferred stock
+ % Common equity X Cost of Common Equity
1. Entity value = (# Shares outstanding X Current share price) + Value of debt
1. Dividend growth model:
Price of stock = D1 / (rs – g), where:
D1 = dividend to be paid in the next period
rs = required return of shareholders
g = growth rate
1. Profitability index (capital budgeting) = PV of future cash flows / Initial cost
1. Payback period: use an assessment of future cash flows to determine in how many years/months the capital will be paid back.
