Knowing your credit utilization percentage is the first step to managing it. Use our quick reference guide below to calculate yours — and learn what to do with the number.
How to Calculate Credit Utilization
The formula is simple:
Utilization % = (Total Credit Card Balances ÷ Total Credit Limits) × 100
Step-by-Step
- Add up all your current credit card balances (check your most recent statements or online accounts)
- Add up all your credit card limits
- Divide balances by limits
- Multiply by 100 to get the percentage
Example
| Card | Balance | Limit | Per-Card Utilization |
|---|---|---|---|
| Chase Sapphire | $1,200 | $8,000 | 15% ✅ |
| Discover It | $800 | $3,000 | 27% ✅ |
| Capital One | $2,500 | $4,000 | 63% ❌ |
| Total | $4,500 | $15,000 | 30% ⚠️ |
In this example, the overall utilization is 30% — right at the danger line. But the Capital One card at 63% is a bigger problem. Scoring models look at both overall and per-card utilization.
What Your Utilization Number Means
| Utilization | Score Impact | Action Needed |
|---|---|---|
| 0% | Slightly negative (shows no activity) | Put a small charge on one card |
| 1-9% | Best possible ✅ | Maintain — you’re in the sweet spot |
| 10-29% | Good ✅ | Keep it here or aim lower |
| 30-49% | Score drag begins ⚠️ | Pay down before statement close |
| 50-74% | Significant negative impact ⚠️ | Prioritize paydown immediately |
| 75-100% | Major red flag ❌ | Stop using the card, pay aggressively |
How Much Should You Pay to Hit Your Target?
Use this formula to figure out exactly how much to pay down:
Amount to Pay = Current Balance - (Credit Limit × Target %)
Example: Your Capital One card has a $2,500 balance on a $4,000 limit (63%). You want to get to 25%.
$2,500 - ($4,000 × 0.25) = $2,500 - $1,000 = $1,500
Pay down $1,500 and your utilization drops to 25%.
Don’t Forget Per-Card Utilization
Your overall number matters, but so does each individual card. Even if your total utilization is 20%, having one card at 90% will hurt your score.
Calculate utilization for every card separately. If any single card is above 30%, take action on that card first.
