Two businesses with identical turnover and identical margins can have completely different funding needs — because one gets its cash back in 40 days and the other in 120. That difference is the working-capital cycle, and it is one of the most powerful levers a promoter has. Shorten it, and you free up cash, reduce borrowing and lift return on capital, without selling a single extra unit.
What the working-capital cycle is
The working-capital (or operating) cycle is the time, in days, between paying for inputs and collecting cash from customers. It has three moving parts:
Operating cycle = Inventory days + Receivable days − Payable days
- Inventory days — how long stock sits before it is sold
- Receivable days — how long customers take to pay
- Payable days — how long you take to pay suppliers (this funds you, so it is subtracted)
The longer the cycle, the more cash is tied up at any moment — and the more working-capital finance you need to bridge it.
How to calculate each component
| Component | Formula |
|---|---|
| Inventory days | (Average inventory ÷ Cost of goods sold) × 365 |
| Receivable days | (Average receivables ÷ Credit sales) × 365 |
| Payable days | (Average payables ÷ Credit purchases) × 365 |
Worked example. A business has inventory days of 60, receivable days of 70 and payable days of 30:
Operating cycle = 60 + 70 − 30 = 100 days
That means roughly 100 days of operating costs are locked up in the business at any time. On ₹12 crore of annual cost, that is around ₹3.3 crore of working capital permanently in play — most of which has to be funded by margin plus a bank limit.
How to shorten the cycle
Every day you cut releases cash. The three levers map to the three components:
Collect faster (receivable days). Tighten credit terms, invoice on dispatch, follow up systematically, and offer early-payment incentives where the maths works. For approved buyer invoices, TReDS and supply-chain finance convert receivables to cash in days rather than weeks — often the single biggest lever.
Hold less stock (inventory days). Better demand forecasting, tighter reorder levels and removing slow-moving SKUs cut the cash buried in inventory without risking stock-outs.
Stretch payables sensibly (payable days). Negotiate longer or structured supplier terms — but never at the cost of early-payment discounts that are worth more than the financing saved.
You do not need more sales to free up cash — you need a shorter cycle. Cutting 20 days off a 100-day cycle on a mid-sized business can release crores that were quietly funding the gap.
Why lenders care too
The working-capital cycle is not just an internal metric — it is exactly what a bank reverse-engineers when it sizes your limit. A business assessed on the turnover method is assumed to run a ~3-month cycle; if yours is genuinely longer, you need to demonstrate it through MPBF and CMA data to get an adequate limit. Either way, a shorter, well-documented cycle means a leaner limit and a stronger balance sheet.
Our supply-chain and working-capital finance team helps both sides of this: structuring the limit to match your real cycle, and putting the financing tools in place to shorten it.
FAQ
What is the working-capital cycle?
The working-capital or operating cycle is the number of days between paying for inputs and collecting cash from customers. It is calculated as inventory days plus receivable days minus payable days. A longer cycle ties up more cash and requires more working-capital finance.
How do you calculate the working-capital cycle?
Add inventory days (average inventory ÷ cost of goods sold × 365) and receivable days (average receivables ÷ credit sales × 365), then subtract payable days (average payables ÷ credit purchases × 365). The result is the operating cycle in days.
How can a business shorten its working-capital cycle?
By collecting receivables faster (tighter terms, systematic follow-up, or financing approved invoices through TReDS/supply-chain finance), holding less inventory through better forecasting, and negotiating longer supplier payment terms where it does not cost more than the financing saved.
Why does the working-capital cycle matter for a bank loan?
Banks size working-capital limits around the length of the cycle. A longer cycle needs a larger limit, but must be justified through MPBF and CMA data. A shorter, well-documented cycle means lower borrowing, a better current ratio and a stronger case at credit committee.
