Credit utilization is your credit card balances divided by your credit limits, and it drives about 30 percent of your credit score. Only payment history matters more.
The free calculator below shows your overall ratio, each card’s ratio, and the exact number of dollars that gets you under the 30% guideline and into the under-10% range where top scores live.
What you’ll learn
- Your overall and per-card utilization
- Whether your ratio is helping or hurting

The formula is simple: balances divided by limits. Carry $3,000 across cards with $20,000 in combined limits and your utilization is 15%. Scoring models read that ratio as a signal of how much you rely on borrowed money.
Two details most people miss: the bureaus generally see the balance from your statement closing date (not what you owe after payday), and scoring models look at each card individually as well as the overall number. One maxed-out card hurts even when your total looks healthy.
What is a good ratio?
Under 30% is the guideline. Under 10% is the goal. Here is how each range typically reads:
| Utilization | Assessment | What it means |
|---|---|---|
| Under 10% | Excellent | Where the highest scores live. Nothing to fix. |
| 10–29% | Good | Inside the guideline; pushing under 10% is the last step. |
| 30–49% | Elevated | Likely costing you points. Paydown starts paying off fast here. |
| 50–89% | High | A heavy drag on your score and a warning sign to lenders. |
| 90%+ | Maxed out | One of the biggest score drags there is. Recovery starts with the first paydown. |
How it affects your score
Amounts owed makes up about 30% of a FICO score, and utilization is the biggest piece of it. Dropping from over 50% utilization to under 10% commonly moves scores 50 to 100 points.
The best part: utilization has no memory. Unlike late payments, which linger for years, high utilization stops hurting as soon as lower balances get reported, usually within 30 to 60 days. That makes it the fastest credit score lever most people have. The full mechanics are in will paying off credit card debt raise my credit score.

Get My Personalized Plan →How to lower utilization
There are only two levers: lower the balances or raise the limits. Five tactics, in order of impact:
1.Pay down the highest-utilization card first
Per-card ratios matter, so the card closest to its limit is usually the fastest score win per dollar.
2.Pay before the statement closes
Issuers typically report the statement balance. Paying mid-cycle lowers the number the bureaus see, even if you pay in full every month.
3.Request a credit limit increase
A higher limit lowers the ratio without a paydown. Best when your income or score has improved, and only if the balances stay put.
4.Spread new spending across cards
Concentrating charges on one card can spike its individual ratio. Distributing them keeps every card under the thresholds.
5.Keep old cards open
Closed cards take their limits with them, pushing your ratio up. Keep them open with a small autopaid charge.
Common mistakes
- Chasing exactly 0% – a small reported balance scores as well as zero, sometimes better. Under 10% is the goal, not zero.
- Ignoring per-card ratios – one card at 95% hurts even when your overall ratio is fine. Check both views in the calculator above.
- Closing paid-off cards – the limit disappears with the card and your ratio jumps. Keep them open.
- Confusing utilization with debt – utilization only counts revolving credit like cards. Your car loan and mortgage do not factor into this ratio.
- Paying after the statement closes – the bureaus already saw the high balance. Time big paydowns before the closing date when a loan application is coming.
