The high-impact one
Credit Scores
Your credit score is a number lenders use to decide whether to trust you — and at what interest rate. A good score can save you thousands on a car or a home.
The biggest levers: pay on time, every time, and don't use too much of your available credit. Time and consistency build it; missed payments wreck it fast.
Pay on time and keep balances low — your score quietly decides the rates you'll be offered.
