How credit utilization works

Utilization compares what you owe on credit cards with the limits available to you. See the number for each card and for all cards together.

Updated by the ToolsToHelp.Me team

If a card has a $1,000 limit and a $250 balance, its utilization is 25 percent: 250 divided by 1,000. Overall utilization uses the sum of balances divided by the sum of limits. The CFPB recommends keeping balances low relative to limits.

Per-card and overall ratios

Both views are useful. One nearly maxed-out card can be worth attention even when your total ratio looks lower. Credit reports may show the balance an issuer reported at a particular time, which can differ from what you see after a payment.

Use the calculator

Enter each card's limit and balance to see the per-card and overall utilization ratios. Open the tool
  1. Open the Utilization Calculator. Start with the two card rows already shown, or add another row.
  2. Enter each card's limit and balance. Use the values you want to model. The tool calculates utilization for that card.
  3. Review the overall result. The tool adds the entered balances and limits, then divides them to show one combined ratio.
  4. Model a payment. Lower a balance to see how the ratios change. Treat the result as a calculation, not a promised score increase.
  5. Check statement timing. If you want a lower balance to be reported sooner, ask your issuer when it reports and review the next statement.

Do not pay interest for a score

The CFPB says paying card balances in full can be good for scores and helps avoid interest. A lower reported balance may help, but paying more than you can afford is not a strategy. Use the calculator to plan within your budget.

Frequently asked questions

Is 30 percent a guaranteed score threshold?

No. Keeping balances low is sound guidance, but scores use different models and there is no single threshold that guarantees a result.

Do I need to carry a balance to build credit?

No. You do not need to pay interest to have a credit history. Paying a statement in full by its due date is generally better for costs.

Does the calculator see my accounts?

No. You enter limits and balances yourself. The calculator shows math based on those values; it does not retrieve a report or predict a score.
