How this is calculated
We map your credit score to a typical mortgage rate tier and show how much a higher score saves on the monthly payment and total interest.
The steps
- Match your score to a FICO rate tier (illustrative national averages).
- Compute the monthly payment and total interest at that rate via the amortization formula.
- Compare against higher tiers to show the dollar value of improving your score.
Assumptions
- Illustrative FICO→rate table updated periodically; the loan amount/term you enter.
Good to know
- Real quotes depend on the lender, product, and the day’s market.
