WHAT MAKES UP A CREDIT SCORE?
Your credit score is determined by an algorithm developed by the Fair Issue Corporation (hence its other name of FICO score). Three corporations, called "credit bureaus", specialize in collecting and reporting on financial histories. Those three companies are Equifax, Experian and TransUnion. While, the exact formula used to calculate your credit score is a tightly guarded industry secret, these companies provide general guidelines about financial behavior that can affect your credit score.
