Formula Used
Per-account utilization = (Current Balance ÷ Credit Limit) × 100
Overall utilization = (Total Revolving Balances ÷ Total Revolving Limits) × 100
Paydown to custom target = Current Balance − (Credit Limit × Target %)
Projected utilization = ((Total Balance + Planned New Charges − Monthly Paydown) ÷ Total Limit) × 100
This calculator focuses on revolving credit usage. Lower percentages usually signal better borrowing control, while high percentages can increase perceived risk and reduce financing flexibility.

Frequently Asked Questions
1. What does credit usage percentage mean?
It shows how much of your available revolving credit you currently use. A lower ratio generally suggests better borrowing discipline and more available capacity.
2. Why track each account separately?
One heavily used card can look risky even when your total usage seems moderate. Account-level review helps spot concentration problems faster.
3. Is lower always better?
Lower is usually safer, but zero activity is not the only goal. Consistent, manageable usage with timely repayment is often more practical.
4. Does this work for installment loans?
This version is designed for revolving credit accounts such as cards and lines. Installment balances behave differently and are not measured the same way.
5. What is a useful target percentage?
Many borrowers aim to stay under 30%, while lower levels such as 10% can provide a stronger cushion. Your own target may depend on timing and goals.
6. Why does projected utilization matter?
It helps you test next-cycle spending and payment plans before they happen. This can improve planning and reduce surprise jumps in usage.
7. What happens if a limit is zero?
The row is excluded from ratio calculations because division by zero is invalid. Update the limit value to include that account correctly.
8. Can I save the results?
Yes. Use the export buttons after calculation to download the visible results as CSV or PDF for review, sharing, or recordkeeping.
