Cash conversion cycle

Before you rely on it

What to check

Look at whether a short cycle comes from fast collection or from stretching payables.

The common error

Where people go wrong with cash conversion cycle

Celebrating a shortening cycle that came entirely from paying suppliers later. That is borrowed from vendors, it can be withdrawn without notice, and it tends to be withdrawn at the worst moment.

Worked through

Cash conversion cycle in plain numbers

A wholesaler holds inventory for 60 days on average, waits 45 days for customers to pay and takes 30 days to pay its own suppliers; the cycle is 60 + 45 − 30, or 75 days. Every day of the cycle is a day the company funds itself. With daily costs near $27,400 (about $10 million a year), 75 days ties up roughly $2.05 million in working capital. Now stretch supplier terms from 30 to 45 days. The cycle falls to 60 days and about $410,000 of cash is freed, without a single extra sale. Shave ten days off inventory as well and the cycle drops to 50, and small operating changes turn into real cash.

Easily confused

Cash conversion cycle and its neighbours

The cash conversion cycle is not the operating cycle, and it is not working capital; the operating cycle covers inventory days plus receivable days and stops before payables enter. The conversion cycle subtracts payables, so it measures how long the company's own money is out. Working capital is a dollar balance on the balance sheet, while the cycle is a length of time; the current ratio and the quick ratio test whether short-term assets cover short-term debts. The cycle tests how fast the business turns operations back into cash. A company can pass every ratio and still run a long, expensive cycle.

In real decisions

Where cash conversion cycle turns up

Finance teams track it monthly to see whether growth is eating cash. Retailers and distributors watch it closely because inventory is their biggest use of cash; lenders use it to size credit lines; owners use it when negotiating terms: shorter customer terms, longer supplier terms or leaner stock all shorten it. Investors compare it across companies in the same industry to see who runs tighter operations. A cycle that keeps lengthening while sales rise is often the first sign of a cash squeeze, well before profit looks weak.

Know the edges

Where cash conversion cycle stops being reliable

The figure depends on how each component is measured. Days of inventory can use cost of goods sold or sales, and averages over a year hide seasonal peaks; companies with negative cycles, such as some subscription and retail models, collect cash before paying suppliers, and that is a strength that only fits certain business models. Comparisons across industries mislead. Use it against the company's own history and against direct peers, and pair it with actual cash flow.

Quick answers

What people ask about cash conversion cycle

Can the cycle be negative? Yes. Some businesses collect cash before they pay suppliers, so the cycle is below zero. Retailers with fast turnover and subscription firms with prepayments are examples. It means suppliers help fund growth.
