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
Per-Card Utilization (Optional)
Add up to 5 individual cards to see per-card utilization.
Card 1
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.
- Credit bureaus typically report balances on the statement closing date, not the payment due date.
- A utilization rate below 30% is widely recommended; below 10% is considered excellent.
- Both overall utilization and per-card utilization affect your credit score independently.

- Paying balances in full each month or making multiple payments per cycle can help keep reported utilization low.
