Credit Utilization Calculator — How Much to Pay Down to Hit 30% and 10%
Enter each card's balance and limit to see your overall and per-card utilization — and the exact paydown to reach 30% and 10%

Your credit cards
Credit utilization = balance ÷ limit. Scoring models look at both your overall ratio and each card individually. Under 30% is the common guideline; under 10% is ideal. Cards with no limit entered are excluded.
23% overall utilization — under 30%, room to optimize
At $3,000 of $13,000 (23%) you're inside the 30% guideline that most scoring guidance treats as the ceiling. The strongest profiles report under 10%. Paying down $1,700 would put you there, and keeping any single card off a high individual ratio matters too.
- ›Pay down $1,700 total to reach the ideal sub-10% utilization
- ›Card 1 is at 48% — your worst reported line; paying $900 on it alone drops it under 30%

How to use Credit Utilization Calculator
Free credit utilization calculator. Enter each card's balance and limit to see your overall and per-card utilization ratio, plus the exact dollar paydown needed to reach the 30% and 10% thresholds.
Your credit utilization ratio is the percentage of your available revolving credit that you are currently using — total balances divided by total credit limits. It is the single largest component of the "amounts owed" category, which makes up 30% of your FICO score, and unlike payment history it has no memory: it is recalculated from the balance your cards report each statement cycle. This credit utilization calculator shows both your overall ratio across all cards and each card individually, then tells you the exact dollar amount to pay down to cross the 30% and 10% thresholds that scoring guidance treats as key breakpoints.
How to use this Credit Utilization Calculator
- 1Enter each credit card's current balance and its total credit limit. Add a row for every revolving account with the "Add card" button.
- 2The utilization percentage for each card appears instantly next to it, colour-coded: green under 10%, amber 10–30%, red above 30%.
- 3The summary shows your overall utilization across all cards — the number most scoring models weigh most heavily.
- 4Read the "pay down to reach 30%" and "pay down to reach 10%" figures — these are the exact dollar amounts needed to cross each threshold across your combined balances.
- 5Check the Decision Engine below for your worst individual card and a per-card paydown target, since scoring models look at both the aggregate and each line separately.
How credit utilization is calculated
Utilization is computed two ways at once: per card (each balance against that card's limit) and in aggregate (all balances against all limits combined). Both matter — a low overall ratio can still be dragged down by one nearly-maxed card. Cards with no limit entered are excluded from the ratio, exactly as a closed or charge card would be.
| Variable | Meaning |
|---|---|
| Per-card util | Card balance ÷ card limit × 100 |
| Overall util | Sum of all balances ÷ sum of all limits × 100 |
| Pay to 30% | Total balance − (0.30 × total limit) |
| Pay to 10% | Total balance − (0.10 × total limit) |
| Reported balance | The balance on your statement closing date — not necessarily $0 even if you pay in full |
Credit utilization example: two cards
- 01Card 1: $2,400 balance on a $5,000 limit = 48% utilization (a red, high-utilization card).
- 02Card 2: $600 balance on an $8,000 limit = 7.5% utilization.
- 03Overall: ($2,400 + $600) ÷ ($5,000 + $8,000) = $3,000 ÷ $13,000 = 23.1% overall utilization.
- 04To reach 30% overall you are already there. To reach 10% overall: $3,000 − (0.10 × $13,000) = pay down $1,700.
- 05To fix the worst card: Card 1 to 30% needs $2,400 − (0.30 × $5,000) = pay down $900 on that card alone.
Result
Overall utilization is 23% (already under 30%), but Card 1 at 48% is a drag on its own. Paying $900 on Card 1 fixes the worst line; paying $1,700 total moves the whole profile into the ideal sub-10% band.
What affects your credit utilization ratio?
Overall vs per-card
Scoring models consider both. A 20% overall ratio looks healthy, but one card at 90% can still cost points. This is why paying down your most-utilized card first often helps the score more than spreading payments evenly.
Statement timing
Cards report the balance on your statement closing date, not your due date. Paying before the statement closes lowers the balance that gets reported — you can pay in full every month and still show high utilization if you charge a lot mid-cycle.
The 30% guideline
Under 30% is the widely cited ceiling, but it is a guideline, not a cliff. Lower is always better for this factor, and the strongest profiles typically report in the single digits.
Closing cards
Closing an unused card removes its limit from the denominator, which raises your overall utilization overnight even though you did nothing wrong. Keeping old cards open (with occasional small use) preserves your available credit.
Credit limit increases
Requesting a higher limit lowers utilization instantly without paying anything down — if you do not increase your spending. A $5,000 limit raised to $8,000 drops a $2,400 balance from 48% to 30%.
Installment loans excluded
Utilization applies only to revolving credit (credit cards and lines of credit). Mortgages, auto loans, and student loans are installment debt and are not part of this ratio.
Tips and things to know
- ✓Pay down your highest-utilization card first, not evenly across cards — a single maxed card hurts more than several moderate ones.
- ✓Make a payment before your statement closing date, not just before the due date, so a lower balance is what gets reported to the bureaus.
- ✓Ask for a credit limit increase on a card you already have — it lowers utilization instantly with no paydown, as long as you keep spending flat.
- ✓Do not close old cards while carrying balances elsewhere; you lose that available credit and your overall ratio jumps.
- ✓Utilization updates every cycle, so this is the fastest-moving score factor you control — a paydown this month can show up on your next report.
Credit Utilization Calculator — bottom line
Credit utilization is the highest-leverage number in your credit profile because it is both heavily weighted — the largest slice of the 30% "amounts owed" category — and instantly changeable. Every other major factor takes months or years to move: payment history needs a track record, and length of credit history literally requires the passage of time. Utilization is different. It is recalculated from whatever balance your cards report each cycle, so a payment made before your statement closing date can lower your reported ratio within weeks. The most common mistake is watching only the overall number. Someone with 18% overall utilization feels safe, but if that is concentrated on one card sitting at 85%, that single line is a drag the aggregate hides. Always fix the worst card first. The second common mistake is closing old cards to "simplify," which quietly removes their limits from your total available credit and pushes utilization up overnight — the opposite of what you want. If your balances are high enough that paying them down to 30% is not realistic this cycle, the lever is a payoff plan, not a quick fix: move to the Credit Card Payoff Calculator to model how extra monthly payments clear the balances driving your ratio, and check the Debt Pressure Index to see how those balances weigh on your overall cash flow.
