FICO Score Tiers and Their Mortgage Rate Prices
Mortgage lenders use FICO scores to assign loan-level price adjustments (LLPAs) — a sliding scale of rate premiums based on default risk at each credit tier. The tiers are not arbitrary. They reflect historical borrower default data going back decades. The key thresholds where significant price changes occur are at 580, 620, 640, 660, 680, 700, 720, and 760. Crossing any of these boundaries upward improves your rate; downward movement worsens it.
2025 estimated mortgage rates and lifetime costs by FICO score — $350,000 loan, 30 years
| FICO Score | Tier | Typical 30-Yr Rate (2025) | Monthly Payment ($350K) | Total Interest (30yr) |
|---|---|---|---|---|
| 760 to 850 | Excellent | 6.50% to 6.75% | $2,212 to $2,254 | $446,320 to $461,440 |
| 740 to 759 | Very Good | 6.75% to 7.00% | $2,254 to $2,329 | $461,440 to $488,440 |
| 720 to 739 | Good-High | 7.00% to 7.25% | $2,329 to $2,404 | $488,440 to $506,440 |
| 700 to 719 | Good | 7.25% to 7.50% | $2,404 to $2,447 | $506,440 to $521,320 |
| 680 to 699 | Fair-Good | 7.50% to 7.75% | $2,447 to $2,506 | $521,320 to $552,160 |
| 640 to 679 | Fair | 7.75% to 8.50% | $2,506 to $2,692 | $552,160 to $619,120 |
| 580 to 639 | Poor (FHA only) | 8.50% to 9.50% | $2,692 to $2,935 | $619,120 to $756,600 |
On a $350,000 loan: FICO 760 at 6.5% = $2,212/month = $446,320 total interest. FICO 680 at 7.75% = $2,506/month = $552,160 total interest. The difference is $294/month and $105,840 over 30 years — purely from credit score, on the same loan amount.
The Specific Points That Save the Most
Not all credit score improvements are equal. Moving from 698 to 718 may not change your rate tier. Moving from 718 to 722 crosses the 720 threshold, which can trigger a significant pricing improvement with many lenders. The most valuable single improvement is crossing any of the major pricing thresholds — particularly 720 and 760.

How to Improve Your Score Before Applying
The fastest and most reliable credit score improvements come from a small set of actions. Most meaningful gains come from paying down revolving credit balances — this alone can add 30 to 60 points within 30 to 45 days. Disputing errors on your credit report can yield 10 to 100+ points if significant errors are found. Every other strategy has smaller or slower effects.
- Pay credit card balances below 10% utilization: At 45% utilization → below 10% yields 30 to 60 point improvement within one billing cycle
- Dispute errors on all three credit reports: 34% of Americans have material errors; use annualcreditreport.com to check all three bureaus free
- Do not open new accounts within 6 months of applying: Each hard inquiry costs 5 to 10 points; new accounts lower average account age
- Become an authorized user on a family member's card: Adding a long-standing, low-utilization card to your profile can add 15 to 40 points
- Pay all accounts on time without exception: Payment history is 35% of your FICO score — one 30-day late payment can drop your score 80 to 130 points
- Do not close old credit card accounts: Closing reduces your total available credit, increasing utilization ratio and potentially lowering score
- Resolve collections under $500: FICO 9 and 10 models ignore paid collections — verify which scoring model your lender uses

Which Credit Score Do Mortgage Lenders Use?
Conventional mortgage lenders use three specific FICO scores: FICO Score 2 (from Experian), FICO Score 5 (from Equifax), and FICO Score 4 (from TransUnion). These are older scoring models that differ from the VantageScore 3.0 scores shown by credit monitoring apps like Credit Karma or Experian's consumer app. When a lender pulls all three scores, they use the middle score. If you have two borrowers, they use the lower of the two middle scores. This means checking your consumer score is informative but not definitive — your actual mortgage score can differ.
For the most accurate pre-mortgage credit picture, purchase your FICO Score 2, 4, and 5 directly from myfico.com. These are the actual scores lenders use. The score shown by free monitoring services (Equifax, Experian apps, Credit Karma) uses VantageScore 3.0 or similar models — often 20 to 40 points different from your actual mortgage FICO.
