What it means
Every time a business buys on credit, the amount owed sits in accounts payable until it is paid. The turnover ratio measures how fast that balance is cleared and refilled over a year.
If the ratio is 12, the company effectively pays off its average supplier balance every month. The ratio is calculated by dividing net credit purchases by the average accounts payable balance.
Net credit purchases are the goods and services bought on credit, less returns and discounts. Using the average of the opening and closing payables smooths out any unusual balance at either end of the period.
Many analysts convert the ratio into days by dividing 365 by the turnover figure. The result is the average number of days the company takes to pay suppliers, often called days payable outstanding.
A ratio of 12, for example, equals about 30 days. Whether a high or low ratio is good depends on context.
A low ratio can mean the company is using supplier credit to conserve cash, which may be smart, or that it is struggling to pay, which is a warning sign. A very high ratio can mean the company is paying faster than required and missing out on free financing.
Ratios should be compared with the company's own history and with its industry, because payment norms differ widely. Many firms do not publish credit purchases, so outsiders often use cost of goods sold as a rough substitute.
That makes the result less precise, though still useful for spotting trends. The ratio also feeds the wider cash conversion cycle, which combines how long inventory sits, how long customers take to pay and how long the company takes to pay suppliers.
Stretching payables shortens the cycle and frees cash, so finance teams often look at all three together. Treating payables in isolation can lead to decisions that help one number and hurt another.
In practice
Real-world examples
Example 1
A grocery chain turns over its payables about 10 times a year and sells most of its stock within weeks. Because customers pay at the till, the chain effectively uses supplier credit to fund inventory. Its treasurer deliberately keeps the ratio moderate, so supplier goodwill stays strong while cash is still used efficiently.
Example 2
A construction supplier sees its turnover fall from 9 to 5 over two years. The CFO investigates and finds that a cash squeeze has forced the team to delay supplier payments. Several suppliers have started asking for payment upfront, which makes the cash squeeze even worse.
Example 3
An investor compares two electronics distributors with similar sales. One has a turnover of 14 and the other 6. The investor asks whether the slower payer has negotiated better terms or is struggling for cash before drawing a conclusion, because the same ratio can signal very different situations.
Think of it
Payable turnover shows how fast you pay your bills-higher means quicker payments to suppliers.
Formula
Calculation
Accounts payable turnover ratio = Net credit purchases / Average accounts payable
Average accounts payable = (Opening accounts payable + Closing accounts payable) / 2
Days payable outstanding = 365 / Accounts payable turnover ratio
A wholesaler buys $1,200,000 of goods on credit in the year. Its payables are $90,000 at the start and $110,000 at the end, so the average is ($90,000 + $110,000) / 2 = $100,000. Turnover = $1,200,000 / $100,000 = 12. Days payable outstanding = 365 / 12 = about 30.4 days.Case study
Seen in the real world
Pinecrest Hardware is a fictional regional retailer that, in this illustrative story, had annual credit purchases of $3,000,000 and average payables of $250,000. Its payables turnover was 12, which meant it paid suppliers in about 30 days.
The finance manager negotiated 45-day terms with its three largest suppliers, which accounted for most of the purchases. After the change, average payables rose to $375,000 and turnover fell to 8, or about 46 days.
That shift released roughly $125,000 of cash into the business without any borrowing. The manager made sure that payments were always made on the due date so that the longer terms did not strain supplier relationships, and the saving was reported to the board at the next meeting.
Watch out
Common mistakes
- Using total cost of goods sold or total sales instead of credit purchases when the data is available. This can distort the ratio.
- Assuming a higher ratio is always better. Paying too quickly gives away free supplier financing.
- Comparing the ratio across industries without adjustment. Payment norms in retail, construction and technology are very different.
Questions
People also ask
What is a good accounts payable turnover ratio?
There is no universal answer, because it depends on the industry and supplier terms. Compare it to the company's own history and to peers.
How is it different from accounts receivable turnover?
Payables turnover measures how fast you pay suppliers, while receivables turnover measures how fast customers pay you. Together they show the balance of cash timing.
Why do lenders care about this ratio?
A falling ratio can warn that the company is delaying payments to conserve cash. A very low ratio may suggest liquidity stress, especially when it is combined with rising borrowing.
