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

- Open the Utilization Calculator. Start with the two card rows already shown, or add another row.
- Enter each card's limit and balance. Use the values you want to model. The tool calculates utilization for that card.
- Review the overall result. The tool adds the entered balances and limits, then divides them to show one combined ratio.
- Model a payment. Lower a balance to see how the ratios change. Treat the result as a calculation, not a promised score increase.
- 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.
