How Your Credit Score Affects Your Mortgage Rate (2026)
Every 20-point FICO tier changes your rate. Here's the exact LLPA grid lenders use and how much a 40-point improvement is worth in dollars.
Mortgage pricing isn't one number. It's a grid: FICO score across the top, LTV down the side. Each cell is a "Loan-Level Price Adjustment" (LLPA) — a price hit that varies based on your specific scenario.
The LLPA grid (simplified, conventional, 2026)
| FICO | LTV ≤60 | LTV ≤75 | LTV ≤80 | LTV ≤90 | |---|---|---|---|---| | 780+ | 0.00 | 0.00 | 0.000 | 0.250 | | 760 | 0.00 | 0.00 | 0.250 | 0.375 | | 740 | 0.00 | 0.125 | 0.375 | 0.625 | | 720 | 0.00 | 0.500 | 0.750 | 0.875 | | 700 | 0.25 | 0.875 | 1.125 | 1.250 | | 680 | 0.375 | 1.250 | 1.625 | 1.750 | | 660 | 0.625 | 1.875 | 2.250 | 2.500 | | 640 | 1.250 | 2.500 | 2.875 | 3.125 | | 620 | 1.500 | 3.000 | 3.500 | 3.750 |
Each "point" of LLPA = ~0.25% in rate, OR equivalent upfront cost.
Real dollar example
$600,000 loan, 80% LTV, 30-year fixed. Same borrower, different FICOs:
- FICO 760: 0.250 LLPA → rate 6.500% → P&I $3,792/mo → $1,365k over 30 years
- FICO 700: 1.125 LLPA → rate 6.875% → P&I $3,941/mo → $1,419k over 30 years
Difference: $54,000 over the life of the loan for being 60 FICO points lower.
What moves your FICO 30-60 points fast
- Pay down revolving balances to <10% of limit (don't close cards)
- Dispute and remove inaccurate negatives
- Get added as authorized user on a long-history high-limit family card
- Resolve any "in collections" — even paid collections weigh down score
- Stop new credit applications 90 days before mortgage app
Don't do this
- Close old credit cards (kills your account-age average)
- Take on a new car loan during mortgage application
- Let your spouse run up balances if both are on the loan
