When it comes to your finances, your credit score can be a big deal. A good credit score can mean big savings (or costs) if you take out a loan. Good credit can also mean lower costs when you get car insurance in some states.

If you have good credit, you’ve worked hard to manage your finances and your loans in a way that shows you are responsible. You are proving that you are a solid risk. But what happens if you slip up? How much could that ruin your score?

According to the major credit bureaus, the damage affects different people differently. One late payment will affect a person with a lower score, but it’ll have a much bigger impact on someone with a really high score. That’s right: if you have great credit now, a mistake could mean a bigger hit to your credit score. Someone with mediocre credit won’t see the same impact as the result of a mistake.

Do you have an excellent credit history and want to keep it that way? Here are some things to avoid if you want to keep that credit score in the good to excellent range:

Missed Payments

The biggest factor in your credit score is your payment history. One missed payment can tank your credit score, if you have excellent credit – by as much as 100 points, according to Equifax.

The longer you wait to pay your bill, the worse the impact. If you are just a couple days late, you might not see a huge change. However, once you reach that 30-day late mark, it’s a big problem.

Do your best to plan your finances so you make your payments on time and in full. Easier said than done, but it’s much easier to stay on track if you have a budget. If you don’t, get working on one. Check out our free budgeting guide.

High Credit Utilization

If you have excellent credit, there’s a good chance you carry small balances on your cards — if you carry them at all. Best results come when you use 30% or less of your available credit each month.

But when you start charging, and that credit utilization number starts to climb, you can see changes to your credit score without realizing it. The closer you are to your limit on the credit cards, the more it impacts your score.

If you end up over the limit on your cards, then your score will suffer. Try to continue keeping balances low. Better yet, pay off your cards each month if you can and avoid paying the interest.

Cosigning on a Loan

One day you may want to help your child or sibling by cosigning on a loan. It might seem like a good idea to cosign on a loan to give them a boost, but think twice before you commit.

Your credit is on the line as soon as you sign on the dotted line, because you accepted responsibility for all payments as a cosigner. Plus, it will look like you have that debt — even if you don’t, and that can affect how much you can borrow if you were to, say apply for a mortgage on a dream home. If the borrower misses a payment, that’s on you as well. You can see your credit score fall.

And if you do cosign, make sure the borrower keeps you up to speed. It may not be ideal to make their loan payments, but at least it can save your credit if you do.
