Credit Utilization Calculator
How much of your revolving credit you are using — overall, and card by card, because the two answers are rarely the same.
Overall utilization
23.3%
$3,500 of $15,000 in use. Your Everyday card is at 60% on its own, which is visible to a lender even though the overall figure is lower.

Card by card
The aggregate hides the outlier. This is the same money viewed one account at a time, which is closer to how it is actually read.
Everyday card
60%
$3,000 of $5,000. $1,500 off this card brings it to 30%.
Travel card
5%
$500 of $10,000 — already at or under 30%.
What this does not tell you
A deliberate omission, and worth stating plainly.
This calculator will not tell you how many points a change in utilization moves your credit score. FICO and VantageScore are proprietary models whose weightings are not published, and the same change lands differently depending on everything else in a file. Any calculator that quotes you a point figure has invented it.
What is knowable is the arithmetic: the ratios above, and the money that moves them. Utilization is also the fastest-moving input in a credit file — it is recalculated from each statement rather than averaged over years, so a payment made before the statement closes shows up on the next report.
How this calculator works
Two divisions and a subtraction. The care is in reporting both ratios rather than the flattering one.
Overall utilization is the sum of your balances divided by the sum of your limits. Per-card utilization is one balance divided by that card’s own limit. Both are reported, along with the worst individual card, because the aggregate routinely hides an outlier.
The paydown figures answer two different questions. Bringing the overall ratio to target takes the total excess over the whole portfolio. Bringing every card to target is card by card, and a card already under target does not earn credit against another card’s excess — so the second figure is always at least the first, and usually more.
A card with no limit entered is shown as having no ratio rather than being treated as fully used. Charge cards with no preset limit are conventionally excluded from utilization, and inventing a limit for one would distort the total.
What is assumed
- The balances you enter are the ones being reported — normally your statement balances, not the balance right now.
- Revolving accounts only. Installment loans are not part of utilization.
- No scoring model is applied, because none is public.
A worked example
Two cards, a comfortable overall figure, and a problem hiding inside it.
| Everyday card | $3,000 of a $5,000 limit |
|---|---|
| Travel card | $500 of a $10,000 limit |
| Overall | $3,500 ÷ $15,000 |
| To reach 30% overall | 3,500 − (15,000 × 30%) |
| To reach 30% on the everyday card | 3,000 − (5,000 × 30%) |
| To reach 30% on every card | 1,500 + 0 |
The overall ratio says nothing needs doing. The everyday card says $1,500 does. Both are true, and only the second is actionable — which is the case for reporting both rather than the one that looks better.
Note also what would happen if the travel card were closed. Its $10,000 limit leaves the denominator, the same $3,500 of debt now sits against $5,000 of limit, and overall utilization goes from 23.3% to 70% without a dollar being borrowed. Try it above.
Questions people ask
Lower is better, and there is no cliff at any particular number — the relationship is continuous, not a threshold you pass. 30% is the figure most commonly repeated, but it is a rule of thumb rather than a published rule, and single-digit utilization is generally better than 30%. Set the target in this calculator to whatever you are aiming at rather than treating any number as official.
Both, which is why this calculator reports both. Scoring models consider aggregate utilization across all revolving accounts and also individual account utilization. A single card near its limit is visible even when the total looks comfortable, and that is the most common way people are surprised by a score.
Nobody can tell you, and a calculator that gives you a number has made it up. FICO and VantageScore are proprietary models whose exact weightings are not published, and the same reduction lands differently depending on everything else in a credit file. What is knowable is the arithmetic: the ratio, and the money that changes it.
Usually the statement balance, which is the balance on your closing date. So paying in full every month does not necessarily report 0% utilization: if you spend $2,000 on a $5,000 limit and pay after the statement closes, 40% was already reported. Paying before the statement date is what changes the reported figure. This is timing, not amount, and it is the single most actionable detail here.
Closing a card removes its limit from the denominator, so unless it also carried a balance, closing it raises your utilization. That is arithmetic, not opinion — try it by removing a zero-balance card above and watching the overall figure rise. There can be good reasons to close a card, such as an annual fee, but improving utilization is not one of them.
Utilization is a revolving-credit measure, so installment loans — mortgages, car loans, student loans — are not part of it. Charge cards with no preset spending limit are generally excluded too. Leave a card's limit blank above if you want it left out; the calculator will show it as having no ratio rather than inventing one.
