Working capital cycle

See how long your cash is tied up between paying suppliers and being paid by customers.

Debtor days = debtors ÷ revenue × 365. Stock days = stock ÷ cost of sales × 365. Creditor days = creditors ÷ cost of sales × 365. Cash cycle = debtor days + stock days − creditor days.

What this means for you

How many days your cash is locked up between paying for what you sell and being paid for it — and what that costs you.

How to read it

  • The cash cycle is the number that matters. Positive means you fund the gap; negative means your suppliers do.
  • The cash tied up figure is real money sitting in debtors and stock rather than in your account.
  • The last line shows what ten days off your debtor days would release. That is usually the fastest cash win in a business.

Watch out for

  • Using a quiet month's balances. Test your peak trading period, where the strain actually happens.
  • Mixing GST-inclusive balances with GST-exclusive revenue, which inflates the day counts.
  • Fixing the cycle by simply paying suppliers later. That buys days and costs relationships.
