Their FAQ says credit scores range from 150-950… when you go to the details of your score it says the following:

* FICO: traditionally between 300 and 850.
* Experian: 330 – 850
* Equifax: 300 – 800
* TransUnion: 150 – 950
* VantageScore: 501 – 990 ( letter grade, A-F )

So they probably pull all of this information and average into a 150-950 point scale. My 796 doesn’t hold up too well, says its only the 61th percentile. Except when I pulled my credit score last year with one of the agencies it had me at 804, which is around 90-95th percentile. Nothing has changed in the past year regarding my credit – two credit cards that I keep low balances on and pay off every month, and never had debt, so I’m not sure why my score according to creditkarma would be much lower.
