What it means
Credit utilisation applies only to revolving credit: business credit cards, overdrafts and drawn-down lines of credit. It does not apply to fixed-term loans with a set repayment schedule, because those have no spare headroom to measure.
The number matters because credit scoring models treat a high figure as a sign of strain. Someone who has already used most of their available headroom has very little left if a big customer pays late or a machine breaks, so the risk of a missed payment rises sharply.
For most credit scoring models it is the second most influential factor after payment history. The useful difference is that payment history takes years to repair, while credit utilisation can be improved inside a single billing cycle simply by paying a balance down.
Lenders look at two versions of the figure: the overall number across every revolving account, and the number on each account taken separately. A business that has maxed out one card while leaving three others untouched can still be marked down, even though the blended figure looks comfortable.
Timing is the nuance most people miss. The balance reported to a credit bureau is normally the one printed on the statement, not the one left after you pay, so clearing the card a few days before the statement date lowers the reported figure without changing your actual spending at all.
Common guidance is to stay below 30%, and below 10% in the months before applying for meaningful borrowing. Raising a limit lowers the ratio just as effectively as paying a balance down, which is why finance teams often request limit increases well ahead of a funding round or a property purchase.
In practice
Real-world examples.
Example
A bakery chain applies for a $400,000 equipment loan. The bank pulls the owners' business card report, sees balances of $76,000 against limits of $95,000, and prices the loan two percentage points higher than quoted. Paying the cards down to $28,500 before reapplying brings the ratio to 30% and restores the original rate.
Example
A freelance consultant charges a $9,000 conference sponsorship to a card with a $10,000 limit. The card is cleared in full the following week, but the statement had already been issued at 90%, and the reported figure drags the credit score down for two months.
Example
A software company asks its bank to lift a corporate card limit from $120,000 to $250,000 ahead of a Series B raise. Spending stays at roughly $60,000 a month, so the reported ratio drops from 50% to 24% without a single dollar being repaid early.
Think of it
“Credit utilization is how much of your credit limit you're using-keep it low.
Formula
Calculation
Credit utilisation = (total revolving balances / total revolving credit limits) x 100
A design agency holds two business cards. Card A has a limit of $50,000 and a statement balance of $17,500. Card B has a limit of $30,000 and a statement balance of $4,500.
Total balances = $17,500 + $4,500 = $22,000
Total limits = $50,000 + $30,000 = $80,000
Overall credit utilisation = $22,000 / $80,000 = 0.275, or 27.5%
Per card: Card A is at $17,500 / $50,000 = 35%, while Card B is at $4,500 / $30,000 = 15%. If the agency pays $6,000 off Card A three days before the statement closes, total balances fall to $16,000 and the reported figure becomes $16,000 / $80,000 = 20%.Case study
Seen in the real world.
Northgate Ceramics is a fictional homewares manufacturer used here purely as an illustrative example. The company funded a seasonal inventory build on two business cards, ending November with $88,000 drawn against $110,000 of combined limits, an 80% figure. Trading was fine and every payment was made on time.
In January the founders approached three lenders for a $600,000 factory extension. Two declined and the third offered a rate well above what the company's profitability suggested it should pay, citing the drawn card balances as evidence of tight liquidity.
The finance manager rebuilt the picture over four months: she moved $50,000 of the balance onto a term loan, negotiated a limit increase to $160,000 on the main card, and set a rule that card balances would be cleared five days before each statement date. By May the reported figure sat near 18%, and the same lender that had declined in January approved the facility at the rate originally expected.
Watch out
Common mistakes.
- Assuming that paying the card in full every month means the reported figure is always zero. The bureau usually sees the statement balance, so heavy spenders can show high utilisation despite never carrying debt.
- Closing an unused card to tidy up the paperwork. Removing that limit shrinks the denominator and can push the overall ratio up overnight.
- Watching only the blended number across all accounts. Lenders also look at each card individually, and one maxed-out account can undo a healthy average.
Questions
People also ask.
Does credit utilisation include term loans and mortgages?
No, it covers revolving credit only, though lenders will separately assess total debt when they review an application.
What figure should a business aim for?
Below 30% as a working rule, and below 10% in the two or three months before applying for significant new credit.
How quickly does the number update?
It refreshes with each monthly statement, so a payment made before the statement date can improve the reported figure within weeks rather than months.
