How is credit utilization calculated?

Divide a reported revolving balance by its credit limit and multiply by 100. Overall utilization divides total reported balances by total revolving limits.

Is 30% credit utilization a hard cutoff?

No. Thirty percent is a common planning benchmark, not a guaranteed score threshold. In general, lower reported utilization is less risky, but scoring results depend on the whole credit file.

Should I pay the highest-utilization card first?

That can improve the most heavily used individual account first. If minimizing interest is the main goal, compare APRs too; the best credit-score priority and interest-saving priority may differ.

Credit Utilization Calculator

Calculate both overall and per-card revolving utilization. Then see how much balance reduction would reach 30%, 10%, or a custom target without pretending any percentage guarantees a particular credit score.

Card	Current balance ($)	Credit limit ($)
Card 1 name	Card 1 balance	Card 1 limit
Card 2 name	Card 2 balance	Card 2 limit
Card 3 name	Card 3 balance	Card 3 limit
Card 4 name	Card 4 balance	Card 4 limit
Card 5 name	Card 5 balance	Card 5 limit

Custom overall target (%)

Leave unused rows at zero. Enter the balance likely to be reported, not necessarily today's pending balance. A card with a balance must have a positive limit.

How Credit Utilization Works

Utilization is a ratio of revolving balances to revolving limits. A $1,500 reported balance on a $5,000 limit is 30%. Overall utilization adds all included balances and divides by all included limits. Credit scoring can also consider each account separately, which is why one nearly maxed-out card may matter even when the overall ratio looks moderate.

Reported balance matters

Issuers commonly report account information periodically rather than after every purchase. Paying before a balance is reported may lower the utilization that appears on a credit report, but reporting schedules vary. Paying by the due date remains essential for avoiding a late payment.

Is 30% the Right Target?

Thirty percent is a familiar educational benchmark, not a cliff where scores suddenly become good or bad. FICO explains that “amounts owed” is one part of its scoring framework, and lower utilization generally signals less dependence on revolving debt. The exact score impact depends on the rest of the file and the scoring model. Use 30% as a first milestone, 10% as a more conservative planning target, and zero-interest debt payoff as a separate objective.

Which Card Should You Pay First?

This calculator ranks cards by utilization because that is the question being modeled. If your goal is to minimize interest, the highest-APR debt usually deserves priority after all minimums are covered. If your immediate goal is reducing a severely used individual line, paying the highest-utilization card can be useful. You can combine the approaches by first bringing an extreme ratio down, then directing extra cash to the highest APR.

Frequently Asked Questions

Does a zero balance hurt utilization?

A zero balance contributes no used credit to the ratio. Whether a particular score changes depends on the entire report and model. You do not need to carry interest-bearing debt to build a payment history.

What happens if I close a card?

If the closed card's limit is no longer counted while your balances remain the same, overall utilization rises. Account age, fees, fraud risk, and spending behavior also matter, so utilization is not the only factor in a closure decision.

Will paying down to 10% guarantee a score increase?

No. It lowers the modeled utilization, but a score can also reflect payment history, account age, credit mix, inquiries, derogatory information, and the timing of reported updates.
