Cash conversion cycle formulae
CCC=ICP+RDP-PDP
Where Inventory conversion period= 365/(cogs/Inventory)
RDP= 365/(Sales/Receivable)
PDP= 365/(COGS/Payable)
Operating Cycle: 365/Purchases X Average Inventories+ 365/Cr.Sales X Avg. Accounts Receivable
A/R turnover
Net credit sales/ Average AR
Inventory turnover ratio
COGS/Average Inventory
Number of days supply in average inventory
360/Inventory Turnover
Pay Back period
Net Initial Investment/After tax annual net cash inflow
IRR
Investment/Annual cash flows= When we divide initial investment/annual cash flows. we will get one percentage . Match it with the table given that is the IRR

6.418
Using the present value table, 6.418 is PV at 9% for 10 periods.
ARR
Accounting income/ Average investment
NPV
PV of net cash Inflows-PV of net cash outflows
Economic Ordering Quantity
Squre root of 2so/c where s= annual salesin units o= cost per purchase order c=carrying cost per unit
Short term debt
Discount %/100-discount% x 365 or 360/Total pay period-Discount period
Cost of loan
Interest paid/ Net funds available
Net cost of debt
Effective interest rate x (1-Tax rate)
Weighted average cost of capital
Investment structure(percentage of investments in total investments) X Cost of investment= WACC
CAPM
R+ B(m-r) C= cost of capital R=risk free rate B= Beta coefficient of Comparable publicly traded common stock, M= Market rate of return . B is referred to as particular change in stock compared to overall market change. Change in stock price /Change in market price
Discounted cash flow method
D/P + G =K Dividend next period/ Stock price + Growth

Residual income
Net income from the income statement-Required Return
Required return=NBV x Hurdle rate
First step= Average invested capital
=sales/capital turnover

ROI
Net Income/ Invested Capital
Net income/sales, sales/capital investment
