You are comparing Apples to Oranges…
To start with – they are NOT the same score and they use different scales. While the 3 major credit bureaus only sell Vantage Scores to consumers, third party monitoring services like freescore.com use their own model to simulate your Fico score. Vantage & Fico run on a different scale and use different formulas, so comparing between the two is like comparing apples to oranges.
Because Fico runs between 300-850 while Vantage uses a 500-990 scale it’s not surprising that the score you see on EX site (Vantage) is significantly higher than what you get on freescore.com.
In my opinion you waste your money with these credit monitoring. More than 90% of all creditors use Fico for their lending decision, so the Vantage score you get on Experian is worthless. The scores you get on third party monitoring services (freescore.com included) are called FAKKO Scores. These can be off more than 100 points from your real Fico, which makes them worthless as well.
If you want a real free credit monitoring service go to CreditKarma.com. They offer free credit score and monitoring services that are based on your Trans-union’s credit report. The score they give for free is pretty accurate – within 50 points of your real Fico.
