Credit Utilization Calculator

How do you calculate credit utilization?

Divide your total credit card balances by your total available credit limits, then multiply by 100. Example: $2,000 in balances against $10,000 in total limits is 20% utilization.

Utilization (%) = (Total Balances / Total Credit Limits) x 100

Most scoring models reward utilization under 30%, with under 10% often considered excellent. Use the calculator above to see exactly how much to pay down to hit your target.

What Is Credit Utilization?

Credit utilization is the percentage of your available revolving credit that you're currently using. It's calculated both per card and across all your cards combined, and it's one of the most influential factors in most credit scoring models, second only to payment history. A lower utilization ratio generally signals to lenders that you're not overly reliant on credit, which tends to correlate with a stronger score.

The Formula

Utilization (%) = (Total Balances / Total Credit Limits) × 100

Both the overall ratio (all cards combined) and the per-card ratio matter. A single maxed-out card can hurt your score even if your overall utilization across all cards looks reasonable, since some scoring models weigh the highest individual-card ratio as well as the aggregate figure.

Why 30% and 10% Are Common Benchmarks

Keeping utilization under 30% is the most commonly cited threshold for avoiding a meaningful score penalty, while under 10% is often associated with the strongest outcomes in many scoring models. These aren't hard cutoffs with a cliff effect exactly at 30% or 10%, but rather general zones: utilization trends downward in a roughly continuous way as your ratio improves, and staying well under 30% consistently is a reliable, low-effort way to support a healthy score.

Fast Ways to Lower Utilization

Pay down balances before the statement closes, not just before the due date, since issuers typically report the statement-closing balance to the bureaus.
Request a credit limit increase on an account in good standing, which lowers your ratio on the same balance without requiring you to pay anything down.
Spread balances across multiple cards rather than concentrating debt on one card, which helps your per-card ratio even if your total balance doesn't change.
Avoid closing old, paid-off cards, since closing a card removes its available limit from your total and can raise your overall utilization even though your debt hasn't increased.

Frequently Asked Questions (FAQ)

1. How do you calculate credit utilization?

Divide your total credit card balances by your total available credit limits across all cards, then multiply by 100. For example, $2,000 in balances against $10,000 in total limits is 20% utilization.

2. What is a good credit utilization ratio?

Most guidance suggests keeping overall utilization under 30%, with under 10% considered excellent by many scoring models. Lower utilization generally correlates with a stronger credit score.

3. Does utilization reset every month?

Utilization is typically recalculated whenever your card issuer reports your balance to the credit bureaus, usually once per statement cycle around your statement closing date, not your payment due date.
