How does my credit score affect my mortgage rate?
Want a lower mortgage rate? It all starts with this one number — your credit score.
Quick headline: Can a bad credit score make your mortgage cost thousands more?
Yes. Lenders use your credit score to set your mortgage interest rate. The higher your score, the lower the rate you’ll be offered. Lower rate = lower monthly payment and dramatically less interest paid over the life of the loan.
How credit scores move mortgage rates
Lenders group borrowers into tiers. Each tier has a different interest rate. Typical bands look like this (approximate examples):
- Excellent (760+): Best available rates
- Very Good (700–759): Slightly higher than best
- Good (660–699): Mid-market rates
- Fair (620–659): Higher rates, fewer options
- Poor (<620): Limited products, much higher rates or denial
A 0.5% to 2% rate difference between tiers is common. On a $400,000 mortgage, a 1% higher rate can mean tens of thousands more in interest.

Why lenders care about your score
Credit scores predict risk. Higher score = reliable borrower = lower chance of missed payments. Lenders price that risk into the interest rate. They also consider:
- Debt-to-income ratio
- Employment history
- Down payment size
- Credit mix and length of history
But the credit score is the clearest, fastest signal that divides borrowers into pricing groups.
Actionable steps to lower your mortgage rate now
- Check your credit report from major bureaus. Look for errors and fix them fast. Errors can shave points off your score.
- Reduce credit utilization: pay down credit cards so balances are under 30% of limits.
- Don’t open new credit lines right before applying. New inquiries can drop your score.
- Patch up late payments: get current and stay current for at least a few months before applying.
- Increase your down payment. A larger down payment can offset a weaker score in the lender’s pricing.
- Shop multiple lenders and compare rate quotes. Different lenders weigh credit factors differently.
Smart negotiation tactics
- Get pre-approved, not just pre-qualified. Pre-approval gives a stronger position and often better pricing.
- Ask lenders to show the rate grid or pricing matrix. If a lender offers a worse rate, point to comparable quotes.
- Consider a mortgage broker who can place your file with multiple lenders quickly.
