- 1Total credit card balances: add up the current balance on every credit card you have.
- 2Total credit limits: add up the credit limit on those same cards.
Understanding your results
Credit utilization under 30% is the commonly cited guideline, with under 10% considered excellent by most scoring models. This applies both to your overall utilization across all cards and, separately, to each individual card — maxing out one card can hurt your score even if your overall ratio looks fine.
The formula
Utilization = (Total balances ÷ Total credit limits) × 100The calculation is a simple percentage of how much of your available credit is currently borrowed. Credit scoring models (like FICO and VantageScore) use this as a proxy for credit risk — someone using a small fraction of their available credit looks lower-risk than someone close to their limits, independent of whether they pay in full each month.
A worked example
$2,400 in combined balances against $10,000 in combined limits gives 24% utilization — inside the commonly recommended under-30% range, though paying it down toward 10% or lower before a big score-sensitive application (like a mortgage) can give a further boost.
Notes for the UK, US and India
Utilization is recalculated whenever your card issuer reports to the credit bureaus — usually around your statement date, not your due date. Paying down a balance a few days before your statement closes (rather than just before the due date) can lower the utilization figure that actually gets reported.
Frequently asked questions
Does paying my card in full every month avoid utilization entirely?+
Not necessarily — most issuers report your statement balance, not your $0 post-payment balance. Even if you pay in full every month, a high balance on your statement date can still show as high utilization to the credit bureaus.
Is 0% utilization the best score?+
Not quite — many scoring models actually favor a small amount of utilization (roughly 1-10%) over exactly 0%, since it shows active, responsible use of credit rather than no usage at all.
Does requesting a higher credit limit help?+
Yes, if your balances stay the same — a higher limit with the same balance lowers your utilization ratio. Just be aware the request itself may involve a hard credit inquiry, which has a small, separate, temporary effect on your score.
