Many people are surprised to see different credit scores depending on where they check. This is completely normal. There isn’t just one credit score, and different lenders use different models depending on the type of loan.
Here’s a simple breakdown to help make sense of it.
Credit Karma and similar apps
Credit Karma and many free credit apps use VantageScore, not FICO. VantageScore is useful for general education and trend tracking, but most lenders do not use it when making lending decisions.
Because of this, the score you see on Credit Karma can be higher or lower than the scores lenders actually pull.
FICO scores you’ll see most often
FICO is the most widely used scoring system, but there are multiple versions.
FICO 8
This is the score most commonly shown by banks, credit cards, and monitoring services. It’s typically used for:
- Credit cards
- Auto loans
- Personal loans
FICO 8 is helpful for monitoring overall credit health, but it is not the score used for mortgages.
Mortgage FICO scores
Mortgage lenders rely on older FICO models, often referred to as mortgage FICO scores:
- Experian FICO 2
- Equifax FICO 5
- TransUnion FICO 4
These models are more sensitive to late payments, collections, and balances, which is why mortgage scores are often lower than FICO 8 or VantageScore.
When applying for a home loan, lenders typically use the middle score of these three.
Why this matters
It’s very common for someone to have:
- A strong Credit Karma score
- A solid FICO 8 score
- Lower mortgage FICO scores
This doesn’t mean anything is wrong. It simply reflects how different scoring models evaluate the same credit information.
Understanding which scores matter — and why — helps set realistic expectations and allows for a more strategic approach to credit improvement.
