Paydown to reach 30% overall
$300.00

Across 2 cards, $3,300 of balances against $10,000 of limits is 33% overall utilization. The CFPB's guidance notes experts advise staying below 30%, with some suggesting under 10% — reaching 30% here means bringing the total balance down to $3,000, a paydown of $300.00. This page computes the ratio only; it does not simulate a score.

Up to 8 cards. Rows with a balance and limit entered count toward the totals.

Enter each card's balance and limit to get utilization per card and across all cards, plus the exact paydown that brings your overall ratio to a target like 30%. Education only: it computes the ratio the CFPB's guidance describes, and it never pretends to simulate your score.

How to use this calculator

  1. 1

    Enter each card's balance and its limit

    Both numbers are on the statement or in the app. Use the reported balance — typically the statement balance, since that is usually what is sent to the bureaus — rather than what is on the card right now after this morning's coffee.

  2. 2

    Look at per-card as well as overall

    One maxed card can matter even when your overall ratio looks comfortable. The tool shows both because scoring models look at both, and averaging your cards together would hide exactly the case worth seeing.

  3. 3

    Use the paydown figure as an arithmetic fact

    The number shown is simply what it takes to bring the overall ratio to your target — total limit times target percent, minus what you owe. It is not a recommendation about where that money should come from, which is a budgeting question this tool does not answer.

  4. 4

    Do not expect a score prediction, from us or anyone

    Scoring models are proprietary and utilization is one input among several. What is verifiable is the ratio and the CFPB's published guidance to keep credit use low. A site that promises you "+40 points" is selling something.

  5. 5

    Model a closure before you close anything

    Removing a card removes its limit from the denominator, which pushes your overall ratio up if you carry balances elsewhere. Delete that card's row here first and watch what happens — it takes ten seconds and occasionally changes the decision.

  • Credit utilizationutilization = balance / limit x 100, per card and across all cards. Verified against CFPB — How do I get and keep a good credit score? (the 30% figure is guidance widely cited by the CFPB, not a scoring-model constant; this site never simulates a score)

Everything you type here is computed in your browser. Nothing you enter is stored on a server, sent anywhere, or shared — there is no account, and your balances never leave your device.

Frequently asked questions

What is a credit utilization ratio?
Your balance divided by your limit, as a percentage — computed per card and across all your cards, because scoring models look at both. A $300 balance on a $1,000 limit is 30% utilization. The CFPB's credit-score guidance notes experts commonly advise staying below 30%, with some suggesting under 10%.
Why does the calculator show per-card AND overall figures?
Because one maxed-out card can matter even when your overall ratio looks fine. Both views come from the same two numbers per card, and this tool reports them side by side rather than averaging the problem away.
How much do I need to pay down to reach 30%?
The tool computes it directly: your total limit times the target percentage is the balance that sits at the target, and anything above that is the paydown needed. It is arithmetic, not advice — where the money comes from is the budget's job, and which target matters for you is not something a calculator can know.
Will paying down to 30% raise my score by X points?
Nobody can tell you that honestly, and this site will not pretend to. Scoring models are proprietary, and utilization is one factor among several. What is verifiable: the ratio itself, how it is calculated, and the CFPB's published guidance about keeping it low — which is exactly what this page provides.
Does closing a card help my utilization?
Closing a card removes its limit from the denominator, which pushes your overall ratio up, not down, if you carry balances anywhere. The calculator lets you model it: delete a card's row and watch the overall figure move. What to do about that is your call.
Which balance do the bureaus actually see?
Typically the statement balance, since that is usually what the issuer reports — so a card paid in full after the statement closes can still show utilization. Report dates vary by issuer, which is why this tool computes the ratio from the numbers you enter rather than producing an estimate of what any bureau holds on a given day.
