Credit Utilization Calculator

How to use this calculator

Utilization is the reported revolving balance divided by the available revolving limit. Lower is generally better, but there is no universal score guarantee.

How credit utilization is calculated

Utilization equals a reported revolving balance divided by its credit limit. A $600 balance on a $2,000 limit is 30%. This calculator shows the current ratio, subtracts a planned payment from the balance, and then calculates an after-payment ratio.

Overall and per-card utilization

For an overall estimate, add the limits and reported balances across the revolving cards you want to include. It can also be useful to calculate each card separately because scoring models and lenders may evaluate both individual accounts and the combined picture.

Example: timing a payment

If a $2,000 limit has an $800 reported balance, current utilization is 40%. A $300 payment reduces the modeled balance to $500, or 25%. Whether that lower amount reaches a credit report depends on the issuer’s reporting date and when the payment posts.

Why 30% is not a magic cutoff

The 30% and 10% outputs are reference scenarios, not promises. There is no universal point that guarantees a score increase, product approval or better APR. A lower reported balance can help the utilization portion of many scoring models, while payment history and other file data still matter.

The CFPB’s credit-score guidance recommends keeping balances low relative to limits and applying only for credit you need. Continue with our utilization guide for new U.S. credit files.
