Utilization is a ratio, not a credit score
Balances divided by limits is one input some models use. It is not a FICO, and we will not invent yours.

Credit utilization is typically revolving balances divided by revolving limits. It is a snapshot, and it can change when you pay or when an issuer changes a limit.
It is not a three-digit score. DontPanic does not pull a FICO or VantageScore, and this page will not guess one.
If you want to see how a card APR compounds, enter the rate on your statement. That math is not a score simulator.
