Credit Utilization Calculator
Credit utilization shows how much of your available credit card limit is being used. This calculator helps you compare overall utilization, find high-utilization cards, and see what changes after a one-time paydown.
Add each card balance and credit limit, choose a target such as 30% or 10%, then compare overall utilization and card-by-card utilization before and after the payment.
Your numbers
Example loaded: three credit cards, a 30% utilization target, and a $1,200 one-time paydown. The result shows overall and card-level utilization after the payment.
Enter your card balances, credit limits, target utilization, and the one-time paydown amount you want to compare.
1) Your credit cards
Enter each card's balance and credit limit. APR is optional unless you choose the highest-APR payment order.
2) Target and one-time paydown
How this calculator works
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 entered payment is applied once using the order you choose. The results show used credit before the payment, the payment applied, used credit after the payment, the target balance, and the remaining paydown needed to reach the target overall and card by card.

Credit utilization overview
Card-by-card utilization
Rows are sorted by current utilization so the highest card-level ratios appear first.

This shows how the entered payment was assigned under the selected payment order.

Utilization looks better. Now check the interest cost.
The utilization target is reached, but at least one APR is high. Check whether the remaining balance is still expensive to carry.
The next calculator will use the largest remaining card balance: Card A, $1,250 after the paydown.
- 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.
- The entered payment is applied once using the selected payment order.
- 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 the target represents |
|---|---|---|---|
| $5,000 | $0 | Reduction from heavily used limits | |
| $3,000 | $0 | Common comparison checkpoint | |
| $2,000 | $150 | Lower revolving utilization | |
| $1,000 | $1,150 | More aggressive target |
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. That makes the remaining paydown easier to understand.
The amount to reach the overall target can be lower than the amount needed to get every card to the target. That's why the result shows both numbers instead of only showing one payoff amount.
Check its remaining paydown gap and APR. A small gap may only need another targeted payment; a larger high-APR balance may need a full payoff comparison.
Choose a payment order: utilization or APR
The payment order changes which card receives the one-time paydown first. Choose the order that matches the immediate goal you want to compare.
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 when one card has the highest utilization and another has the highest APR. If the same card leads both, either order may begin with the same balance.
The calculator shows how one entered payment changes utilization. It doesn't calculate long-term interest savings or payoff time, so use the linked payoff calculators when the remaining balances need a monthly plan.
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 can be useful. Overall utilization shows the total relationship between balances and credit limits. Card-level utilization shows whether one card is still using a high share of its own limit.
Does lowering utilization guarantee a higher credit score?
No. Lowering utilization can help credit health, but scores can also depend on payment history, account age, credit mix, recent inquiries, and how 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.
Is 30% the right target?
A 30% target is a common checkpoint. It's not a guarantee of a particular credit score result. You can use 30%, 10%, or another target to compare how much paydown would be needed.
