Personal Finance Basics — The number lenders use to decide if they trust you.
Your credit score is a single number, roughly 300 to 850, that tells lenders how trustworthy you are as a borrower. A higher score unlocks loans at lower interest rates, which can save thousands.
Hard vs soft inquiry: A hard inquiry (applying for new credit) can lower your score slightly. A soft inquiry (checking your own score) does not.
Closing your oldest card can actually hurt your score by shortening your history and cutting your available credit.
