Credit Utilization Calculator
Calculate your credit utilization ratio from your balance and credit limit, and find how much to pay down to hit a target utilization.
How to use this tool
- Enter your total reported balance.
- Enter your total credit limit across the same cards.
- Set your target utilization (under 30% is a common guideline).
- Read your utilization, available credit, and the paydown needed to reach the target.
Find your credit utilization ratio and how much to pay down to hit a target. Utilization is a major credit-score factor — generally, lower is better.
Formula
Utilization = Total balance ÷ Total credit limit × 100%
Available credit = Credit limit − Balance
Paydown to target = max(0, Balance − Limit × Target %)
How it works
Credit utilization is the share of your available revolving credit that you are using: total balance divided by total credit limit. It is one of the most influential factors in common credit-score models, second only to payment history. Lower is generally better; many guides suggest keeping it under 30%, and the lowest scores tend to cluster among people with very low single-digit utilization.
This tool reports your current ratio, the unused credit you have left, and exactly how much you would need to pay down to reach a target utilization (target balance = limit × target percent). Utilization is usually measured per card and across all cards; raising a limit or spreading balances changes the ratio without changing what you owe. Because scoring models read the balance that posts to your statement, paying before the statement closes can lower the reported number.

Worked example
$3,000 balance on a $10,000 limit, 30% target
- Utilization = 3,000 ÷ 10,000 × 100% = 30.00%.
- Available credit = 10,000 − 3,000 = 7,000.
- Target balance = 10,000 × 30% = 3,000.
- Paydown to target = 3,000 − 3,000 = 0 (already at target).
Credit utilization = 30.00%, paydown to target = $0.00
Utilization by balance on a $10,000 limit
| Balance | Utilization | Available credit |
|---|---|---|
| $500 | 5.00% | $9,500 |
| $1,000 | 10.00% | $9,000 |
| $3,000 | 30.00% | $7,000 |
| $5,000 | 50.00% | $5,000 |
| $7,000 | 70.00% | $3,000 |
| $9,000 | 90.00% | $1,000 |
| $10,000 | 100.00% | $0 |
Key terms
- Credit utilization
- The ratio of balances to credit limits, expressed as a percent; lower is generally better for scores.
- Available credit
- Credit limit minus current balance — the room you have left to spend.
- Per-card vs aggregate utilization
- Scoring looks at both each card's utilization and the total across all cards.
- Statement balance
- The balance reported to credit bureaus when your statement closes; this is what utilization is usually based on.
Frequently asked questions
- What is a good credit utilization ratio?
- Many guides suggest keeping utilization under 30%, and lower is generally better. People with the highest scores often keep it in the single digits, but there is no single official cutoff.
- Does paying down my balance raise my score immediately?
- Scores update when the lower balance is reported to the bureaus, typically when your statement closes. Paying before the statement date can lower the reported utilization sooner.
- Should I close a card I do not use?
- Closing a card removes its limit from the total, which can raise your overall utilization. Many people keep no-fee cards open to preserve available credit.
