Key Formulas Quick Reference

Working Capital Metrics

DSO = (A/R รท Revenue) ร— 365
DIO = (Inventory รท COGS) ร— 365
DPO = (A/P รท COGS) ร— 365
CCC = DSO + DIO - DPO

NWC Forecasting

A/R = (DSO / 365) ร— Revenue
Inventory = (DIO / 365) ร— COGS
A/P = (DPO / 365) ร— COGS
ฮ” NWC = Beginning NWC - Ending NWC

Depreciation

Annual Depr. = (Cost - Salvage) / Life
Excel: =SLN(cost, salvage, life)

PP&E Roll-Forward

End Gross PP&E = Beg + Capex - Disposals
End Accum Depr = Beg + Depr - Disp Depr
Net PP&E = Gross - Accum Depr
