How do the three credit agencies calculate our credit scores and why are they different from one another?

Here is what Credit Recovery Group’s Certified Credit Specialist, Rosie Rosin has to say:

“Credit agencies calculate our credit score according to the time when the creditor’s information is sent to them. Every credit agency has its own system to calculate our credit score and they do not communicate with each other”.

The main reason why credit scores can vary is because they use different scoring models. A FICO® Score is calculated using a different formula than a VantageScore. And while most credit scores use a scale of 300 to 850, that isn’t always the case.
