Turnover Ratios and Cash Conversion Cycle Calculator (Inventory, Receivables, Payables)
Calculates inventory, receivables and payables turnover and their day counts (DIO, DSO, DPO) plus the cash conversion cycle to show how fast working capital turns.
Things to keep in mind:
- Using period-end balances instead of averages distorts results for seasonal businesses.
- Include trade receivables and payables only; exclude shareholder receivables, tax payables and similar items.
- Keep VAT treatment consistent between receivables and revenue, otherwise day counts are off.
- Compare with industry averages; the tool suggests no thresholds.

About this tool
Turnover ratios show how many times inventory, receivables and payables are renewed over a period; the day counts show how long each takes on average. Together they give the cash conversion cycle, which shows how fast working capital turns.
Formulas
- Inventory turnover = COGS / Average inventory; DIO = Average inventory × Days / COGS
- Receivables turnover = Net revenue / Average receivables; DSO = Average receivables × Days / Net revenue
- Payables turnover = Purchases / Average payables (COGS if no purchases entered); DPO = Average payables × Days / Purchases (COGS if none)
- Operating cycle = DIO + DSO
- Cash conversion cycle = DIO + DSO − DPO
The day count is 365 or 360. Turnover ratios are rounded to 2 decimals and day counts to 1 decimal, half up (HALF_UP); cycles are added from unrounded values. If a balance is 0, its turnover is shown as 0.
Example 1: revenue 3,650,000, COGS 2,190,000, average inventory 300,000, receivables 500,000 and payables 240,000 over 365 days give DIO = 300,000 × 365 / 2,190,000 = 50.0, DSO = 500,000 × 365 / 3,650,000 = 50.0, DPO = 240,000 × 365 / 2,190,000 = 40.0; operating cycle 100.0 and cash conversion cycle 60.0 days. Inventory turnover is 7.30, receivables turnover 7.30 and payables turnover 9.13.
Example 2 (with purchases, 360 days): revenue 1,200,000, COGS 900,000, inventory 150,000, receivables 200,000, payables 250,000 and purchases 1,000,000 give DIO 60.0, DSO 60.0, DPO 90.0 days and a cash conversion cycle of 30.0 days.
How to read the result: A higher turnover means the item is renewed more often; short DIO and DSO mean less cash is tied up in stock and receivables. A long DPO means suppliers' credit is used for longer. A short cash conversion cycle means the business ties up its cash for less time; a negative one means payments to suppliers take longer than the stock and receivable periods (supplier-financed). Suitable levels vary by industry; compare the result with your own earlier periods and industry averages. To see other ratios too, look at the Financial Health Analysis tool.
How to use
- Enter period revenue and cost of goods sold, and choose 365 or 360 days.
- Enter average inventory, receivables and payables (leave unused items at 0).
- Optionally enter period purchases for the payables turnover.
- Press Calculate.
Notes
Turnover ratios are rounded HALF_UP to 2 decimals and day counts to 1 decimal. A turnover is shown as 0 when its balance is 0 (not computable). Cycles are added from unrounded values.

Frequently asked questions
Cost of goods sold divided by average inventory. COGS of 2,190,000 and average inventory of 300,000 give 7.30 turns, so stock is renewed about 7.3 times a year. Days inventory outstanding over 365 days is 50.0.
Days sales outstanding: the average number of days it takes to collect from customers. It is average receivables divided by net revenue, multiplied by the number of days. With receivables of 500,000 and revenue of 3,650,000 over 365 days, DSO is 50.0 days.
Yes. Businesses that sell for cash and pay suppliers late (e.g. grocery) can have a negative cycle, meaning suppliers finance them. For example, with no stock or receivables and a 60.8-day payment period, the cycle is -60.8 days.
Payables turnover and DPO are then calculated on cost of goods sold (COGS) instead of purchases. If you know your purchases, entering them brings the result closer to reality.
Follow your accounting policy; the day counts scale with the number of days. Turnover ratios are not affected by the day count.
