Working capital cycle: how to calculate and shorten it
Most small businesses that run short of cash are not losing money. They are waiting for it. Rupees paid to suppliers today sit in stock, then in an unpaid invoice, and return to the bank account weeks or months later. The length of that journey is the working capital cycle, and it decides how much money the business needs just to keep trading. Knowing your number turns a vague feeling of tightness into something you can measure and manage. This article shows how to calculate it from figures already in your books, and what you can do to shorten it.

Working capital in one line
Working capital = current assets − current liabilities. Current assets are what will turn into cash within a year: stock, receivables, bank balances. Current liabilities are what you must pay within a year: trade creditors, statutory dues, short-term borrowings. A positive figure means short-term assets cover short-term dues. But the figure alone says nothing about timing, and timing is where businesses get caught.
The cash conversion cycle
The cash conversion cycle measures timing. It counts the days between paying for your purchases and collecting from your customers.
Cash conversion 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 after the sale.
- Payable days — how long you take to pay your suppliers.
A worked example
Take a hypothetical trader with annual sales of ₹3.65 crore, all on credit, and a cost of goods sold of ₹2.92 crore. That is ₹1 lakh of sales and ₹80,000 of cost per day. The balance sheet shows stock of ₹36 lakh, receivables of ₹60 lakh and trade payables of ₹24 lakh.
| Measure | Formula | Result |
|---|---|---|
| Inventory days | Stock ÷ daily cost of goods sold | ₹36 lakh ÷ ₹80,000 = 45 days |
| Receivable days | Receivables ÷ daily credit sales | ₹60 lakh ÷ ₹1 lakh = 60 days |
| Payable days | Payables ÷ daily cost of goods sold | ₹24 lakh ÷ ₹80,000 = 30 days |
| Cash conversion cycle | Inventory + receivable − payable days | 45 + 60 − 30 = 75 days |
What the number tells you
This trader funds 75 days of operations before customers’ money comes back. In rupees, stock and receivables of ₹96 lakh are supported by ₹24 lakh of supplier credit, leaving ₹72 lakh that must come from the owner’s capital or from borrowing. That ₹72 lakh is not a one-time need. It is permanently locked in the cycle for as long as the business trades at this level.
Three points follow. A longer cycle means more money tied up for the same sales. A cycle that lengthens from year to year is an early warning, often of slow-moving stock or customers stretching payment. And comparison is useful mainly within your own trade: a distributor, a job-work manufacturer and a services firm will have very different normal cycles.
Why growth eats cash
Suppose the same trader wins new customers and sales rise by half. If the cycle stays at 75 days, the money locked in it also rises by half, from ₹72 lakh to about ₹1.08 crore. The extra ₹36 lakh has to be found before the profit on the new sales is collected. A business can be profitable on paper every month and still be unable to pay salaries, because profit is counted when the invoice is raised and cash arrives only when it is paid.
Before accepting a large order on long credit, work out how much extra stock and receivables it will create and how you will fund them until the buyer pays. Growth that outruns its funding is a common reason sound businesses default.
Ways to shorten the cycle
Collect faster
- Invoice on the day of dispatch, not at the month end. Every day of delay in billing is a day added to receivable days.
- Put the credit period on the purchase order and the invoice, and follow up before the due date rather than after it.
- Offer a small early-payment discount where the margin allows, and compare its cost with what borrowing for the same days would cost.
- Review credit limits buyer by buyer. A customer who always pays 40 days late is, in effect, borrowing from you interest-free.
Hold less stock
- Identify slow-moving and dead items and clear them, even at a lower margin.
- Reorder on the basis of actual sales and lead times, not habit or bulk-discount temptation.
- Track stock by item, so that fast movers are not starved while cash sits in slow ones.
Use supplier credit sensibly
Negotiating a longer credit period from suppliers reduces the cycle directly. But stretching payments beyond agreed terms damages the relationship and, where your supplier is a micro or small enterprise, can attract statutory interest under the MSMED Act. Agree terms openly rather than delay quietly.
Finance the gap that remains
Some part of the cycle cannot be squeezed further, and that part is what working capital finance is for. A revolving limit funds stock and receivables as a whole. Invoice discounting converts specific receivables into cash sooner. In the example above, bringing receivable days down from 60 to 45, by better collection or by discounting, would release ₹15 lakh. Which facility fits which need is covered in cash credit, overdraft, term loan or invoice discounting.
If you keep your books in Vaanij Accounts, stock, receivable and payable figures are already there, and with your consent they can pre-fill an application on Vaanij Capital, where regulated banks and NBFCs make the lending decision.
- Cash conversion cycle = inventory days + receivable days − payable days.
- The cycle shows how many days of operations you must fund from capital or borrowing.
- Growth increases the cash locked in the cycle before it increases cash in the bank.
- Faster invoicing, firm credit control and leaner stock shorten the cycle at no borrowing cost.
- Finance the gap that remains with a facility that matches it.
