Credit Utilization Calculator
Find out your credit utilization ratio—how much of your available credit you're using—and how much to pay to reach a 30%, 10%, or custom target.
Enter your credit card balances and limits to calculate overall utilization, compare individual cards, and see how a one-time payment changes your results.

Utilization looks better. Now check the interest cost.
You've reached the utilization target, but at least one card has a high APR. Check what the remaining balance could cost in interest.
The next calculator will use the largest remaining card balance: Card A, $1,250 after the paydown.
This calculator adds your credit card balances and credit limits to estimate overall utilization, then calculates the utilization ratio for each card separately. The target percentage is converted into a dollar target balance, so you can see the balance level that matches the target instead of only seeing the percentage.
The calculator applies your planned payment once, following the order you choose. The results show your balances before and after the payment, the amount applied, and how much more you'd need to pay to reach your target overall and on each card.
Assumptions used
- Credit utilization is calculated as balance ÷ credit limit.
- Overall utilization uses total balances divided by total credit limits.
- Card-level utilization is calculated separately for each card.
- Your planned payment is applied once using the payment order you select.
- Highest utilization first lowers the highest card-level ratio toward the target before moving to the next card.
- If the highest-utilization order reaches the target on every card and payment remains, the remaining payment is applied by APR when every remaining card has an APR; otherwise, it is applied to the largest remaining balance.
- Highest APR first uses APR only for sorting; this calculator doesn't calculate interest charges.
- Credit limits are treated as fixed unless you manually change them.
- The result doesn't include pending purchases, pending payments, fees, statement timing, or issuer reporting dates.
How much to pay down at common utilization targets
The listed cards have a $3,350 combined balance and a $10,000 combined credit limit, producing 33.5% overall utilization. After applying $1,200, the estimated combined balance is $2,150, or 21.5% utilization. Each row shows any additional paydown needed to reach that target.

| Target utilization | Target combined balance | Additional paydown needed | What it means |
|---|---|---|---|
| $5,000 | $0 | Half your available credit in use | |
| $3,000 | $0 | Common rule of thumb | |
| $2,000 | $150 | Below the 30% guideline | |
| $1,000 | $1,150 | Lower utilization goal |
How much is 30% or 10% of your credit limit?
Use this reference table to find the balance that equals 30% or 10% of a single credit card's limit. For your actual paydown amount, subtract the target balance from what you currently owe, or enter your cards in the calculator above.

| Credit limit | Balance at 30% | Balance at 10% |
|---|---|---|
| $500 | $150 | $50 |
| $1,000 | $300 | $100 |
| $1,500 | $450 | $150 |
| $2,000 | $600 | $200 |
| $3,000 | $900 | $300 |
| $5,000 | $1,500 | $500 |
| $7,500 | $2,250 | $750 |
| $10,000 | $3,000 | $1,000 |
| $15,000 | $4,500 | $1,500 |
These balances are at 30% or 10%. To be under either target, your balance must be lower than the amount shown.
How much should you pay to reach 30% utilization?
Calculation: $1,100 − ($3,000 × 30%) = $200. Pay slightly more if you want to be below a target rather than exactly at it.
Overall utilization vs card-level utilization
Overall utilization uses all listed balances divided by all listed credit limits. Card-level utilization checks each card separately. Both can matter because a low total ratio can still hide one card that's close to its own limit.
Overall utilization
This is the total used credit divided by total credit limit. It gives you the broadest view of how much available credit is being used.
Card-level utilization
This checks each card by itself. A single card can stay above target even when the overall ratio has already improved.
Target balance
The target percentage is converted into a dollar balance.
Reaching the overall target can take less money than getting every card to that target, so the results show both amounts.
Check how much more you'd need to pay and the card's APR. If the balance is large and the APR is high, try the Credit Card Interest Calculator to see what carrying it could cost.
Overall utilization is low, but one card is above 30%
Before the payment, overall utilization is 14.3% even though Card A is above 30%. Paying $300 toward Card A brings that card to 30% and lowers overall utilization to 10%. Use the calculator's highest-utilization-first order to see how one payment changes individual cards and the combined total.
Choose a payment order: utilization or APR
The order you choose determines which card gets the payment first. Pick the one that matches what you want to do right now.
Highest utilization first
Use this order when the priority is lowering cards with the highest balance-to-limit ratios or bringing every card closer to the selected target.
Highest APR first
Use this order when reducing the cost of carrying the balances matters more than lowering the highest card-level ratio first.
Compare both orders
Run both if one card has the highest utilization and another has the highest APR. If the same card tops both lists, either order starts with that card.
The calculator applies your planned payment once. For interest costs or monthly payoff timelines, use the linked calculators.
Credit utilization calculator FAQ
What is credit utilization?
Credit utilization is the percentage of available revolving credit currently being used. If a card has a $1,000 balance and a $5,000 limit, that card's utilization is 20%.
Should I focus on overall utilization or each card?
Both matter. Overall utilization shows how much of your total available credit you're using. Card-level utilization shows whether any one card is using a high share of its own limit.
Does lowering utilization guarantee a higher credit score?
No. Lower utilization can help your score, but scores also depend on payment history, account age, credit mix, recent inquiries, and when balances are reported.
What payment order should I use?
If your goal is to lower utilization, highest utilization first is usually the clearest starting point. If your main goal is reducing interest, highest APR first may be more useful.
What is a good credit utilization ratio?
There isn't one credit utilization ratio that's right for everyone. Lower utilization generally helps your score. Below 30% is a common guideline, while below 10% is a lower target some experts recommend. Use the calculator to see how much you'd need to pay toward either target.
