Your FICO score is a three-digit number generated by a proprietary model from Fair Isaac Corporation, and it is the single most commonly used credit score by US lenders. When you apply for a mortgage, a car loan, or a new credit card, there is a very good chance the decision — and the interest rate offered — is heavily influenced by this number.
What changed in 2026
- FICO 10T (trended data) expanded. More lenders adopted models that look at how balances and utilization moved over time, not just a single snapshot — rewarding consistently paying down balances.
- UltraFICO and FICO Score XD gained wider use for borrowers with thin files, incorporating banking history (account age, balance patterns) for people with limited credit history.
- BNPL reporting went mainstream. Buy Now Pay Later providers increasingly report to the bureaus; late BNPL payments now affect FICO scores in ways they did not a few years ago.
- Mortgage lenders continued requiring FICO — despite VantageScore gaining consumer-facing share, Fannie Mae and Freddie Mac still mandate FICO scores for conventional mortgages.

How to raise your score
- Pay every bill on time, every month — even one missed payment can drop a score 50–100 points and stays on your report for up to 7 years.
- Lower credit utilization below 30% — and ideally below 10% for the highest scores. Pay balances before the statement closing date.
- Do not close old cards — even unused cards extend your average account age and add to total available credit, both of which help.
- Limit new credit applications — each hard inquiry costs a few points temporarily; multiple applications in a short window compound the hit.
- Diversify gradually — adding an installment loan (credit-builder loan, auto loan) when you only have cards can improve credit mix over time.
Common mistakes
Paying the minimum and calling it done. Payment history is about whether you paid — not whether you paid in full. But carrying a high balance hurts utilization (30% of the score), so minimum payments keep you in a low-score rut.
Closing credit cards after paying them off. Closing a card reduces total available credit, raises utilization on remaining cards, and eventually drops the average account age. Almost always counterproductive for credit score.
Assuming disputing removes accurate information. You can dispute errors — and should. But a legitimately late payment or collection stays for up to 7 years (10 for bankruptcy). No company can legally delete accurate negative items faster.
Not monitoring your report. Errors are common. Pull your free reports from annualcreditreport.com regularly (all three bureaus) and dispute any inaccuracies.
What to skip
- Credit repair services charging $50–$100/month to "fix" your credit — anything legitimate they do, you can do yourself for free: dispute errors, write goodwill letters, manage utilization.
- Rent-a-tradeline schemes that add you as an authorized user on a stranger's account — lenders and FICO have adapted to flag these patterns.
- Opening multiple new accounts to "diversify" quickly — new account inquiries and the drop in average age outweigh the mix benefit in the short term.
FAQ
How is a FICO score different from a VantageScore?
Both use the 300–850 scale and the same underlying credit report data, but they weight factors differently and have different versions. Most mortgage and auto lending decisions use FICO; many free score services show VantageScore. Your two scores are usually close but not identical.
How many FICO scores do I have?
Dozens — FICO creates specialized scores for mortgage, auto, and bankcard lending, each with multiple versions. The "classic" FICO 8 is most cited. When a lender pulls your score they specify which version.
How long does it take to build a good score from scratch?
With a credit-builder loan or secured card, responsible use for 12–24 months can get a thin-file borrower into the 680–720 range. Getting to 750+ typically requires 3–5+ years of clean history.
Can I get a mortgage with a score below 620?
FHA loans allow scores down to 500 (with 10% down) or 580 (with 3.5% down). Conventional loans (Fannie/Freddie) generally require 620+. Below 620, options are limited and rates are substantially higher.
