Credit utilization calculator
Utilization is balance divided by credit limit — both overall and per card. High utilization can affect mortgage readiness through minimum payments and underwriting signals. We do not promise a specific score change; this shows the math from numbers you enter.
How utilization is calculated
Per-card utilization is balance divided by limit for each account you enter. Overall utilization is the sum of balances divided by the sum of limits. Both can matter — a single maxed card can hurt readiness even when the aggregate looks moderate.
Statement balances often drive what reports to credit bureaus, so paying in full after the statement may still show utilization until the next cycle. Enter what you expect to report, not what you intend to pay tomorrow.
Per card: utilization = balance ÷ limit Overall: utilization = sum(balances) ÷ sum(limits)
How to read your percentages
We do not promise score changes — scoring models are proprietary. Focus on what you control: balances, limits, and the minimum payments that flow into DTI.
Compare overall and per-card columns. If one card drives the worst percentage, that is often the first payoff target before a mortgage application — even if another card has a higher APR for avalanche math.

- Lower utilization generally supports mortgage readiness, but there is no verified universal threshold here.
- Requesting a higher limit without increasing spending can lower utilization if the issuer approves — approval is not guaranteed.
- Avoid new charges while paying down before you apply.
When this tool fits
Use it when you know your balances and limits and want the math lenders and scoring models watch. Follow with the DTI tool to see how the same balances affect required minimum payments.
If utilization is high because minimum payments trap you, switch to the payoff planner and minimum payments guide before considering consolidation.
Track progress monthly, not daily — utilization moves when statement balances change, not when you make a mid-cycle payment that has not reported yet.
Worked example with your current inputs
Overall utilization from your inputs: 54.5% on $5,450 balances against $10,000 in limits.
Card 1: 64.0% ($3,200 / $5,000). Card 2: 60.0% ($1,800 / $3,000). Card 3: 22.5% ($450 / $2,000).
Pay down the card with the highest utilization first if you are preparing for a mortgage — even when another card has a higher APR for avalanche interest savings.
Results
| Card | Balance | Limit | Utilization |
|---|---|---|---|
| Card 1 | $3,200 | $5,000 | 64.0% |
| Card 2 | $1,800 | $3,000 | 60.0% |
| Card 3 | $450 | $2,000 | 22.5% |

No application, no pressure — the next step below fits these numbers better than an application would.
Overall utilization = sum(balances) ÷ sum(limits) = $5,450 ÷ $10,000 = 54.5%
