Credit scores are calculated based on ALL the information in a consumers' file at the time the score is requested. Without detailed data about the complete context, even a guess would be inaccurate. Credit scoring software is also proprietary. If Fair Isaac told us how they figure out scores, they would be giving away their business secrets.
There is a lot of general information on the factors taken into consideration. You can find general guidelines at www.ftc.gov and at www.myfico.com
