Days inventory outstanding (DIO)
— days
Days sales outstanding (DSO)
— days
Days payable outstanding (DPO)
— days
Cash conversion cycle
— days

A shorter (or negative) cash conversion cycle means a business needs less working capital – Amazon and Apple famously collect from customers before paying suppliers. A lengthening CCC can signal problems collecting cash or selling stock.

How it works

Enter revenue, cost of goods sold and the beginning and ending inventory, receivables and payables.

Tips

  • Use consistent periods (a year or a quarter) for flow figures and period-end values for balances.
  • Average opening and closing balances when a ratio mixes a flow with a stock.
  • Benchmark against competitors in the same industry.
  • Read the ratio together with others – profitability, liquidity and efficiency tell different stories.

Common mistakes to avoid

  • Using sales instead of cost of goods sold for inventory ratios.
  • Mixing gross, operating and net profit.
  • Ignoring one-off items that distort a single year.

What each result means

  • Days inventory outstanding (DIO) = ([Beginning inventory] + [Ending inventory])÷2÷[Cost of goods sold]×[Days in the period]
  • Days sales outstanding (DSO) = ([Beginning accounts receivable] + [Ending accounts receivable])÷2÷[Revenue]×[Days in the period]
  • Days payable outstanding (DPO) = ([Beginning accounts payable] + [Ending accounts payable])÷2÷[Cost of goods sold]×[Days in the period]
  • Cash conversion cycle = [Days inventory outstanding (DIO)] + [Days sales outstanding (DSO)] – [Days payable outstanding (DPO)]

Example values

How the main result changes when Revenue changes and everything else stays at the example values above:

Revenue Cash conversion cycle (days)
1,000,000 85.8
1,500,000 66.3
2,000,000 56.6
2,500,000 50.7
3,000,000 46.8
4,000,000 42

Formula

DIO = average inventory ÷ COGS × 365DSO = average receivables ÷ revenue × 365DPO = average payables ÷ COGS × 365CCC = DIO + DSO − DPO

Worked example

Inputs — Revenue: $2,000,000; Cost of goods sold: $1,200,000; Beginning inventory: $180,000; Ending inventory: $220,000; Beginning accounts receivable: $150,000; Ending accounts receivable: $170,000; Beginning accounts payable: $100,000; Ending accounts payable: $120,000; Days in the period: 365.
Results — Days inventory outstanding (DIO) = 60.8 days; Days sales outstanding (DSO) = 29.2 days; Days payable outstanding (DPO) = 33.5 days; Cash conversion cycle = 56.6 days.
