How to Use the Credit Score Loan Rate Calculator
Your FICO score is one of the biggest factors lenders use to price a loan. This calculator applies representative interest-rate tiers for common personal and auto loans across the standard FICO ranges, so you can see how your score, loan amount, and term translate into an estimated rate, monthly payment, and total interest.
Scores of 800 and above (Exceptional) generally get the best available rates, while each lower band — Very Good (740-799), Good (670-739), Fair (580-669), and Poor (below 580) — typically carries a noticeably higher rate. Even a modest amount financed can add up to a large difference in total interest across tiers.
The results also show how much extra interest you'd pay compared to someone in the top tier at the same loan amount and term. These figures are general estimates, not a quote — your actual rate depends on income, debt-to-income ratio, and the individual lender's underwriting.

Yes. Actual rates depend on income, debt-to-income ratio, loan type, and the specific lender's pricing. This tool gives a general reference based on FICO tier, not a guaranteed quote.
Moving up even one tier can noticeably lower your monthly payment and total interest. Check the extra interest versus the top tier to see how much room you have to save.
