What Is a FICO Score? The Number Lenders Actually Use
A FICO score is the credit score most lenders actually pull, built from your credit report on a 300-to-850 scale. Here is what it is, how it differs from other scores, and why it matters.
A FICO score is the credit score most lenders actually use, and that is the single most important thing to know about it. Created by the Fair Isaac Corporation (that is where the name comes from), it runs on a 300-to-850 scale and is calculated from the information in your credit reports. When a lender says they “pulled your credit,” they are almost always looking at some version of your FICO score.
FICO vs “credit score” vs VantageScore
People use these terms interchangeably, which causes a lot of confusion:
- Credit score is the umbrella term for any three-digit prediction of how you handle borrowed money.
- FICO score is the specific, dominant brand of credit score. Roughly 90% of top lenders use it.
- VantageScore is a competing model built by the three credit bureaus. It is what many free apps show you, which is exactly why the number in your app often does not match what a lender pulls. We break that gap down in is Credit Karma accurate?
Same person, same day, different models: different numbers. That is normal, not a mistake.
What goes into a FICO score
Your FICO score is built from five factors, weighted like this:
| Factor | Weight |
|---|---|
| Payment history | 35% |
| Amounts owed (utilization) | 30% |
| Length of credit history | 15% |
| New credit | 10% |
| Credit mix | 10% |
The top two do most of the work. If you want the practical version of how to move these, that is the whole point of the how to build credit guide.
Why there is more than one FICO score
Here is the part that surprises people: you do not have a single FICO score either. FICO releases updated versions (FICO 8 is the most common, with FICO 9 and 10 newer), plus industry-specific versions like the FICO Auto Score for car loans and a bankcard version for credit cards. Different lenders use different versions, and they may pull from a different bureau.
“Your FICO score” is really a family of scores. Which one shows up depends on who is asking and what they are lending you money for.
That is not a flaw you can fix, just a reality worth knowing so you are not thrown when the number moves between lenders.

Frequently asked questions
What is a FICO score?
A FICO score is a credit score created by the Fair Isaac Corporation, ranging from 300 to 850. It is built from the information in your credit reports and is the score most lenders use to decide whether to approve you and what interest rate to offer.
What is the difference between a FICO score and a credit score?
FICO is a type of credit score, not a separate thing. "Credit score" is the general term, and FICO is the specific brand of score most lenders rely on. Other credit scores exist too, like VantageScore, which is why your number can differ depending on which score you are looking at.
Is a FICO score the same as VantageScore?
No. Both run on a 300-to-850 scale and use similar factors, but they are different models built by different companies. FICO is used by most lenders, while VantageScore is what many free apps like Credit Karma show. The same person can have a different FICO and VantageScore at the same time.
What FICO score do lenders use?
It depends on the loan. There are many FICO versions: FICO 8 is common for credit cards, while mortgage lenders often use older versions and pull all three bureaus, and auto lenders may use a FICO Auto Score. So even your FICO can vary depending on who is checking and why.
