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

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

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
