What moves your score most
Two things dominate: paying on time, and how much of your available credit you are using. Consistent on-time payments and low utilization are the biggest wins.
Why the score matters
A higher score unlocks lower interest rates on car loans, mortgages, and credit cards. On a $250,000 home loan, a great score can save tens of thousands over the life of the loan.
How to build one
Use a small amount of credit, pay it off in full every month, and never miss a due date. Time and consistency do the rest — there are no real shortcuts.
Example
Using $300 of a $3,000 credit limit and paying it in full monthly keeps your utilization at 10% — a sweet spot most scoring models like.
