Credit Utilization: The Factor You Control Most
Credit utilization makes up 30% of your score and is the easiest factor to improve quickly. Step-by-step guide from Credit Booster credit specialists.
Mastering Credit Utilization
Credit utilization is the ratio of your credit card balances to your credit limits. It's the second most important factor in your score, and the one you can change fastest.
The Math
Per-card utilization: Balance ÷ Limit Overall utilization: Total balances ÷ Total limits
Optimal Utilization Ranges
| Utilization | Impact |
|---|---|
| 0% | Not ideal, shows no activity |
| 1-9% | Excellent, maximum score benefit |
| 10-29% | Good, acceptable range |
| 30-49% | Fair, starting to hurt |
| 50%+ | Poor, significant score damage |
