Keep your credit utilization low

How much you owe on your loan, vs how much is available, makes a big difference. Experts suggest keeping your balances at 30% or less of how much is available to borrow.

This means that closing unused credit lines can hurt your credit score as your borrowing availability drops.

Pay on time

Missed payments sting your score, so making even the minimums on time is important. Try to set up your loans and credit cards on autopay so you don’t miss anything.

Become an Authorized User

One of the quickest ways an unexperienced borrower can build their score is to draw on someone else’s credit history. Becoming an authorized user on their credit card or loan. Even if you don’t buy anything, your score can benefit from their usage of that credit line.

Credit History matters

Closing a credit line or loan account with a long history can hurt your score. While it can feel good to close unused accounts, consider whether you should close one with a shorter history first.

Only apply when needed

Don't open accounts just to have a better credit mix—it probably won't raise your credit score. Newer and short-term accounts hurt your average history. Additionally, new credit inquiries impact your score negatively as well.

Pay down maxed out balances first

If you use multiple credit cards and credit lines, pay down the maxed-out balances first. This helps your credit utilization rate drop and improves your score.
