Credit Utilization Rate Calculator

Calculate your credit utilization rate — the percentage of your available revolving credit that you are currently using. Keeping this below 30% is generally recommended for a healthy credit score.

### Overall Utilization

Total Credit Card Balances ($)

Total Credit Limits ($)

### Per-Card Utilization (Optional)

Add up to 5 individual cards to see per-card utilization.

Card 1

Balance ($)

Credit Limit ($)

Add Another Card

Calculate Utilization

#### Formula

Overall Credit Utilization Rate (%) = (Total Revolving Balance ÷ Total Revolving Credit Limit) × 100

Per-Card Utilization Rate (%) = (Card Balance ÷ Card Credit Limit) × 100

Example: If you have a total balance of $2,500 across all cards and a total credit limit of $10,000:

Utilization Rate = ($2,500 ÷ $10,000) × 100 = 25%

#### Assumptions & References

Only revolving credit (credit cards, lines of credit) is included — installment loans (mortgages, auto loans) are excluded.
A utilization rate below 30% is widely recommended; below 10% is considered excellent.
