How Credit Scores Work

What actually moves a credit score, what doesn't, and why paying down cards helps faster than most people expect.

Section 1 of 6

A credit score isn't a judgment of your character or a report card on your life. It's a statistical estimate of one narrow thing: how likely you are to fall 90 or more days behind on a payment in the next couple of years.

That framing helps in two ways. First, it takes the sting out — a low score means the math currently sees risk, not that you've failed at something. Second, it makes the score feel changeable, because it is. Scores are recalculated every time a lender requests them, using whatever is in your credit report at that moment. Change the report, and the score follows — often within one or two billing cycles.

Most U.S. lenders use FICO scores or VantageScore, both running roughly from 300 to 850. The exact number varies by model and bureau, which is normal — you have many scores, not one.
