There are many different scoring models used by creditors to determine your credit worthiness and each weighs factors slightly differently depending on their intended use. These include include FICO, VantageScore 3.0, and the scores generated by each credit bureau (Experian, Equifax and TransUnion).
Because all consumers have multiple credit scores generated at a given time, it is important to understand which credit score another app or website is using when comparing to Truebill.
Here are a few of the reasons why your Truebill score may differ from other sites:
A different scoring model was used
Your Truebill credit score is calculated using the VantageScore 3.0 scoring model and your Experian credit report. While this is a very popular model used by 20 of the top 25 lenders, it is not used by all websites. In addition, some sites may use VantageScore 3.0 criteria but source the different underlying credit report from a different credit reporting agency (for example Equifax or TransUnion).

Your lenders may not report to all credit agencies
Not all lenders send data to each credit agency. For example, some lenders may only report to Experian, while others may only report to Equifax. This can result in a different account set being used to calculate your score. If you aren't sure which credit agencies your lenders are reporting to, you can contact your lenders or credit agencies to ask.
Even when lenders do report to all credit agencies, they may not send updates at the same time. There maybe also be some variation in the time it takes for each agency to process your data. The best way to compare these details is to look at the underlying Credit Report that is used in a particular score.
