| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Total Balance | Sum of all current debt on credit cards | USD ($) | $0 – $50,000+ |
| Total Limit | Sum of all credit limits on all cards | USD ($) | $500 – $100,000+ |
| Utilization % | The resulting usage ratio | Percentage (%) | 0% – 100% |

($1,800 / $2,000) × 100 = 90%. This high ratio will likely cause a significant drop in your credit score because you are using almost all of your available credit.

($1,500 / $15,000) × 100 = 10%. This is considered an excellent ratio and will help improve credit score outcomes significantly.
