What it means
Trade receivables are unpaid customer invoices, and trade payables are unpaid supplier invoices. Setting one against the other gives a fast read on which side of the trading cycle is absorbing cash and which side is providing it.
The commercial relevance is straightforward cash. If customers take 60 days to pay while suppliers insist on 30, the company must fund that 30 day gap from its own bank balance or an overdraft, and this ratio makes the imbalance visible as a single number.
It is calculated by dividing the trade receivables balance by the trade payables balance, both taken from the same balance sheet date. Many analysts also compare the two in days, using debtor days and creditor days, because raw balances ignore differences in the volumes flowing through each side.
There is no universally correct level. Retailers who take cash at the till and pay suppliers later often run well below 1.0, while professional services firms invoicing corporate clients routinely run above 2.0.
The nuance is that a comfortable-looking ratio can conceal bad debts. If a third of the receivables balance is more than 90 days overdue, the ratio overstates how much cash is genuinely on its way, so it should always be read next to an ageing analysis.
In practice
Real-world examples.
Example
A design agency invoicing large corporate clients on 60 day terms while paying freelancers within 14 days runs a ratio of about 3.0. The founders decide to negotiate 30 day client terms on all new contracts to reduce the amount of working capital tied up.
Example
A grocery chain reports a ratio of 0.15 because nearly all sales are settled instantly at the till while suppliers are paid on 40 day terms. The negative working capital cycle means growth generates cash rather than consuming it.
Example
An industrial equipment supplier watches its ratio drift from 1.3 to 1.9 over three quarters. Investigation shows two large customers stretching payment while the company continues to pay its own suppliers on time, and the board approves a stricter credit policy.
Think of it
“This compares what customers owe you to what you owe suppliers-credit balance between them.
Formula
Calculation
Trade Receivables to Trade Payables Ratio = Trade Receivables / Trade Payables
An industrial equipment supplier closes its financial year with trade receivables of $2,400,000 and trade payables of $1,600,000.
Ratio = $2,400,000 / $1,600,000 = 1.5
The company is owed $1.50 by customers for every $1.00 it owes suppliers. The difference of $800,000 is net trading credit being funded from the company's own resources.
Now suppose the credit control team collects $400,000 of overdue invoices and uses the cash to settle supplier accounts early, taking payables down by the same amount. Receivables fall to $2,000,000 and payables to $1,200,000, giving $2,000,000 / $1,200,000 = 1.67. The ratio has risen even though the company's cash position improved, which shows why the number always needs interpreting rather than reading as a score.Case study
Seen in the real world.
Halden Instruments is an invented manufacturer used here as an illustrative example. It reported a trade receivables to trade payables ratio of 1.5, which the sales director presented as evidence of a healthy order book.
The new financial controller pulled an ageing report and found that $520,000 of the $2,400,000 receivables balance was more than 90 days overdue, most of it owed by a single distributor in financial difficulty. Once a realistic provision was made against that balance, the collectable receivables were closer to $1,900,000, giving an effective ratio of about 1.2.
In this fictional case the practical outcome was a change in behaviour rather than a change in the ratio itself. Halden introduced credit limits, stopped shipping to accounts more than 60 days overdue, and began reporting the ratio alongside an ageing summary so that nobody could read the headline figure in isolation again.
Watch out
Common mistakes.
- Treating a high ratio as automatically good, when it usually means the company is lending to customers more than suppliers are lending to it.
- Including non-trade items such as tax balances, prepayments or intercompany loans, which distorts both sides of the calculation.
- Reading the ratio without an ageing analysis, so that uncollectable invoices are counted as if they were cash on the way.
Questions
People also ask.
What is a good ratio?
It depends entirely on the business model, but many industrial and business-to-business companies sit between 1.0 and 2.0, while cash retailers sit far below 1.0.
Does the ratio replace debtor and creditor days?
No, it complements them; days measures show how long each side takes, while the ratio shows the relative size of the two balances at a moment in time.
Can the ratio be improved without collecting cash?
Only artificially, for example by delaying supplier payments, which raises payables and lowers the ratio while making the underlying position worse.
