What is the cash conversion cycle?
The cash conversion cycle (CCC) measures the number of days between paying cash for inventory and collecting cash from customers. It combines three operating metrics — how long stock sits (DIO), how long customers take to pay (DSO) and how long you take to pay suppliers (DPO). A shorter cycle means less money tied up and less need for bank finance; a negative cycle means suppliers are effectively funding your business.
Formulas
- DIO (Days Inventory Outstanding) = Inventory ÷ COGS × 365
- DSO (Days Sales Outstanding) = Receivables ÷ Credit Sales × 365
- DPO (Days Payables Outstanding) = Payables ÷ Purchases (or COGS) × 365
- Operating Cycle = DIO + DSO
- Cash Conversion Cycle = DIO + DSO − DPO
Worked example
A distributor has annual sales of ₹1.2 crore, COGS ₹84 lakh, inventory ₹14 lakh, debtors ₹18 lakh and creditors ₹10 lakh. DIO = 14 ÷ 84 × 365 = 60.8 days. DSO = 18 ÷ 120 × 365 = 54.8 days. DPO = 10 ÷ 84 × 365 = 43.5 days. CCC = 60.8 + 54.8 − 43.5 = 72 days. Daily sales are ₹32,877, so roughly ₹23.7 lakh of cash is permanently locked in the cycle. Cutting DSO by just 10 days frees about ₹3.3 lakh.
How to shorten the cycle
- Reduce DIO: tighter reorder levels, clear slow-moving SKUs, just-in-time purchasing
- Reduce DSO: invoice immediately, offer 1–2% early-payment discount, collect advances, use UPI/payment links, follow up with an ageing report
- Increase DPO: negotiate 45–60 day credit — but note the MSME 45-day rule below
The MSME 45-day rule
Section 43B(h) of the Income-tax Act (from FY 2023-24) disallows the deduction of any amount payable to a micro or small enterprise that is not paid within 45 days (15 days if no written agreement). Stretching DPO on MSME suppliers can therefore cost you a tax deduction and attract interest under the MSMED Act at three times the RBI bank rate.
Average vs closing balances
If your year-end stock or debtors are unusually high or low, switch to "opening & closing" mode so the tool averages them — this is how analysts and banks compute the ratios. Use a 90-day or 30-day period for quarterly or monthly monitoring.
Frequently Asked Questions
What is a good cash conversion cycle?
Lower is better. Retail and FMCG distribution run 20–45 days; manufacturing 60–120 days; e-commerce and supermarkets often negative. Compare with your own industry and track the trend.
Can CCC be negative?
Yes, when DPO exceeds DIO + DSO. You collect from customers before paying suppliers — ideal for cash flow, common in retail and subscription businesses.
Should I use total sales or credit sales for DSO?
Credit sales give the accurate DSO. If you cannot separate them, total sales will understate DSO for a business with substantial cash sales.
How is CCC different from the operating cycle?
Operating cycle = DIO + DSO (inventory to cash). CCC subtracts the supplier credit you enjoy (DPO), showing the net period you must finance yourself.
