Your score sets your rate, and rate sets your payment
Lenders sort credit scores into bands, and each band maps to a different interest rate. A gap of just a few dozen points can swing your rate by a quarter point or more — thousands of dollars over the life of the loan. Rate, not your score itself, is what actually changes your monthly payment.
- Higher score bands generally unlock lower rate tiers.
- A small rate difference compounds over a 30-year loan.
- Payment history and credit utilization drive most of the score.
