How to use

  • In Quick, enter Total credit limit and Total balance, then calculate.
  • Check the guidance bands: under 30% is a common target; under 10% is an optimization zone.
  • Use Pay-down targets to see how much you’d need to reduce balances to hit 30% or 10%.
  • Use Per-card to see individual card utilization and optionally auto-fill totals.
  • Use Share / Copy link to save settings (encoded in the URL). Use Save as image for a watermark card.

Tips

  • Utilization is typically based on revolving credit (credit cards/lines), not installment loans.
  • Paying early (before statement close) can reduce what’s reported.
  • Avoid maxing out a single card even if your overall is okay.

FAQ

Does per-card utilization matter?

Many people track both overall and per-card utilization because some models may consider both.

Should I include cards with a zero balance?

Yes—zero-balance cards increase your total available credit and can lower overall utilization.

What if my utilization is over 30%?

It’s a guideline. Consider paying balances down, paying early, or adjusting how balances are spread across cards.

Do you fetch my credit report or bank data?

No. This tool is local-only and uses only the numbers you type in.
