Credit Utilization Calculator
Credit utilization compares what you owe on your cards to what those cards let you borrow. It’s the second most influential factor in your credit score after payment history, and the fastest to change.
This calculator shows your ratio on each card and across all of them, and tells you what you’d need to pay down to reach a given level.
Enter the balance and credit limit for each of your credit cards. Use the balance that appears on your statement, not what’s currently pending — that’s the figure your issuer reports.
Include credit cards, store cards, and personal lines of credit. Leave out auto loans, mortgages, and student loans — those are installment debts and don’t affect utilization.
What it would take to move it
Why one card can matter more than your total
Most people check their overall utilization and stop there. But FICO looks at each card individually as well as your combined figure, which means the two can tell very different stories.
Say you have three cards. One has a $500 balance on a $10,000 limit. Another has $400 on $8,000. The third has $950 on a $1,000 limit. Your overall utilization is about 10%, which looks excellent — but that third card is at 95%, and it’s scored on its own.
This is why paying down your largest balances doesn’t always move your score the way you’d expect. The card doing the damage may be a small one you weren’t thinking about.
How credit utilization works
It’s balances against limits, nothing else. Your income doesn’t factor in. Neither does how much you pay each month. Utilization is a snapshot of what you owe relative to what you’re allowed to borrow.
Only revolving balances count. That means credit cards, store cards, and personal lines of credit — the kind of account where paying it off frees the credit back up for reuse. Auto loans, mortgages, student loans, and personal loans are installment debts: they have a fixed balance that only goes down, no limit to measure against, and no effect on this number at all. It’s why a $30,000 car loan does nothing to your utilization while a $3,000 card balance can move it noticeably.
Both numbers matter — each card and the total. FICO looks at your overall ratio and at your individual cards. One card near its limit can affect your score even if your combined utilization looks fine.
Your utilization is only measured once a month. Your card issuer sends one balance figure to the bureaus each cycle, and it’s typically taken when your statement closes — not when your payment is due. So the number that counts isn’t your balance today; it’s whatever it was on that date.
FAQ
Does this calculator use 30% as the target?
No. It shows what you’d need to pay to reach both 30% and 10%, but it doesn’t treat either as pass-or-fail. According to FICO, there’s no evidence of a sudden score drop the moment you cross 30% — the scoring works as a gradient, so any reduction counts and there’s no line you have to clear.
Which balance should I enter?
Whatever appeared on your most recent statement. That’s the snapshot your issuer sends to the bureaus, so it’s the number the scoring models see — not your live balance today.
What if I don’t know my exact credit limit?
Check your statement or your issuer’s app; it’s listed on both. An estimate will give you an approximate result, but limits are worth getting right, since they’re the denominator here and a guess of a few thousand dollars will noticeably shift your answer.
Should I include my mortgage or car loan?
No — those are installment debts and they work differently. This tool covers revolving accounts only — cards and lines of credit.
Why does this show each card separately?
Because that’s how FICO evaluates them. A card sitting near its limit can weigh on your score even when your combined figure looks fine, and a single overall percentage would hide that entirely.
Is my card with a zero balance hurting me?
Not at all — it’s helping. An unused card contributes its full limit to your available credit while adding nothing to your balances, which pulls your overall ratio down. That’s one reason closing an old card can backfire.
How soon would paying down my balance show up here?
Immediately in this calculator, since it works from what you type. On your actual credit report, it takes until your issuer’s next report, which is usually one billing cycle.
