There are dozens of free credit score services. The catch is that they don’t all show the same number, and some show you a score that’s irrelevant to how lenders actually evaluate you. The score your credit card app shows might be 30 to 50 points different from the score a mortgage lender pulls. Understanding which score you’re looking at and which one matters is worth the five minutes it takes to sort out.
FICO vs VantageScore
FICO scores are used in about 90% of lending decisions. When you apply for a mortgage, auto loan, or credit card, the lender is almost certainly looking at a FICO score. FICO scores range from 300 to 850.
VantageScore is the main competitor, developed by the three credit bureaus (Equifax, Experian, TransUnion). It uses the same 300 to 850 range. Some lenders use it, but far fewer than FICO. The scores can differ by 20 to 50 points or more because the models weigh factors differently.
Many free credit score services show you a VantageScore. Credit Karma, for example, shows VantageScore 3.0 from TransUnion and Equifax. That number is useful for tracking trends (is your score going up or down?) but it’s not necessarily the number a lender will see.
Free FICO scores
Discover Credit Scorecard provides your FICO Score 8 from Experian. You don’t need to be a Discover customer. Anyone can use it. This is one of the most commonly used FICO models for credit card and personal loan decisions. It updates monthly.
Many bank and credit card issuers provide your FICO score for free through their apps. Chase, Bank of America, Citi, American Express, Capital One, and Wells Fargo all offer some version of a FICO score to cardholders. Check your issuer’s app or website.
Experian offers a free FICO Score 8 through their website and app. It’s based on your Experian report and updates monthly. They’ll try to sell you premium monitoring, but the basic score is free.
Free VantageScore services
Credit Karma shows your VantageScore 3.0 from TransUnion and Equifax. It’s free and updates weekly. The number is useful for monitoring changes but may not match what a lender sees.
Credit Sesame provides a VantageScore from TransUnion. Similar to Credit Karma in usefulness: good for trend watching, not necessarily what a lender pulls.
Which one to check
If you’re about to apply for a mortgage, the lender will pull FICO scores from all three bureaus and typically use the middle score. Knowing your FICO from one bureau gives you an approximation.
For credit cards and personal loans, FICO Score 8 from Experian is a good reference point. Discover’s Credit Scorecard gives you exactly this for free.
For general monitoring, Credit Karma’s VantageScore works fine. If the trend is up, your FICO is probably up too. If something drops by 50 points on Credit Karma, something changed on your report and you should investigate even if the exact number is different.
Why the numbers differ
Different scoring models, different data. FICO and VantageScore weight payment history, utilization, account age, credit mix, and new credit differently. Each model also comes in multiple versions (FICO 2, 4, 5, 8, 9, 10; VantageScore 3.0, 4.0). Each version uses slightly different calculations.
On top of that, your score from Equifax might differ from Experian or TransUnion because not all creditors report to all three bureaus. If one bureau has a collections account that another doesn’t, the scores from those bureaus will be different.
The takeaway: don’t fixate on the exact number. Use the score directionally. If you’re at 720 on one service, you’re probably in the 700 to 740 range across models and bureaus. That’s good enough for planning purposes.
How often to check
Monthly is enough for most people. Check your score, look for any unexpected changes, and move on. If you’re actively working on improving your score or about to apply for a large loan, checking weekly on Credit Karma gives you faster feedback on whether your efforts are working.
Pull your actual credit reports (not just scores) from AnnualCreditReport.com at least once a year. The reports show the details behind the score: all your accounts, payment history, balances, and any negative marks. The score summarizes the report, but the report is where you find errors and track specifics.
