Why Your Credit Score Can Drop After Paying Off a Loan

A Reward That Feels Like a Penalty

You just made the final payment on your car loan. A message flashes on the screen: “Congratulations, your loan is paid in full.” You feel a sense of relief and accomplishment. A few weeks later, you check your credit score, expecting to see it jump. Instead, it dropped 15 points. This feels like a penalty for doing the right thing. It is not. The drop is a side effect of how credit scores are built.

The Score Is a Snapshot, Not a Judgment

A credit score is a numerical summary of your credit report at one moment in time. It is calculated by a formula. The formula’s goal is to predict how likely you are to pay a bill 90 days late in the next 24 months. That is it. The score does not measure your character or your net worth. It just measures a specific kind of risk. To do this, the formula looks at several factors, and one of them is called “credit mix”.

Your “Credit Mix” Just Got Thinner

Lenders have found that people who successfully manage different types of debt are, on average, less risky borrowers. The scoring formulas from FICO and VantageScore reflect this observation. There are two main categories of debt.

• Installment loans: You borrow a fixed amount of money and pay it back in equal payments over a set period. Car loans and mortgages are common examples, as are personal loans.
• Revolving credit: You have a credit limit you can borrow against, pay back, and borrow from again. Credit cards and lines of credit are the main types.

When you had a car loan and a credit card, you had a “mixed” credit file. You were successfully managing both types of accounts. But the moment you paid off that car loan, that active installment loan was gone. If it was your only one, your file now shows active experience with only one type of credit: revolving. The scoring formula sees this change. It now has less diverse information to judge your creditworthiness. The score drops a little. It is a small, automated adjustment based on a change in the data.

What About the Age of Your Accounts?

Another key part of your score is the length of your credit history. Older accounts are better. A long history gives lenders more data to see how you handle your obligations over time. Many people worry that paying off a loan will make an old account disappear, hurting their average account age.

This is a partial myth. When you pay off a loan, the account is marked as “closed, paid in full.” This is a positive status. That closed account will remain on your credit report for up to 10 years, according to the major credit bureaus. During that time, it continues to age and contribute positively to your credit history length.

So why the score drop? The drop is not about the account’s age disappearing from your report. It is almost entirely due to the change in your credit mix described earlier. The closing of the account is simply the event that triggers the change in your active account portfolio.

The Credit Card Exception

Paying off installment loans is different from paying off credit cards. Paying down your credit card balance is almost always a huge boost for your score. This is because of your credit utilization ratio. This ratio is the percentage of your available credit that you are currently using. For example, if you have one card with a $10,000 limit and a $5,000 balance, your utilization is 50%.

Lower is better. Keeping it below 30% is a good rule of thumb, and below 10% is even better. Paying your balance down directly and immediately lowers this ratio, which typically helps your score.

The problem arises if you close the credit card account after paying it off. Closing the card erases that credit limit from your total available credit. If you have balances on other cards, your overall utilization ratio will instantly increase. That can hurt your score. For instance, imagine you have two cards, each with a $5,000 limit. One has a $0 balance, and the other has a $2,500 balance. Your total limit is $10,000 and your total balance is $2,500. Your utilization is 25%. If you close the card with the zero balance, your total limit drops to $5,000. Your balance is still $2,500, but your utilization is now 50%. Your score would likely fall.

Never Pay Interest Just to Build a Score

So should you keep a loan open and keep paying interest just to maintain your credit mix? Absolutely not.

A credit score is a tool. The goal of personal finance is not to get the highest possible score. The goal is to build wealth and financial security. Paying interest on a debt you could otherwise clear is spending real money for a handful of temporary score points. It is a bad trade.

Consider the cost. If you have a $5,000 personal loan balance, the interest costs you money every month.

Paying that loan off saves you all future interest payments. That saved money can be used for investing, saving for a down payment, or building an emergency fund. The small, temporary dip your score takes is insignificant compared to the real financial gain of eliminating debt. Your score will recover as you continue to pay your other bills on time.

The One Time a Small Score Drop Matters

There is an exception to this advice. A small change in your credit score normally does not matter much. But it matters a great deal if you are about to apply for a very large loan, specifically a mortgage.

When you apply for a mortgage, lenders use your credit score to determine your interest rate. Even a small difference in your score can change your rate, which can add up to thousands of dollars over the life of the loan. The Consumer Financial Protection Bureau provides tools showing how scores affect mortgage costs. A score of 750 might get you a better rate than a score of 730. The difference can be substantial.

If you are planning to buy a home within the next six to twelve months, and you have an installment loan that is almost paid off, you might consider a specific strategy. It can make sense to wait until *after* your mortgage has closed to make that final loan payment. This preserves your credit mix and keeps your score as high as possible right when it matters most. For nearly everyone else, in any other situation, paying off debt as soon as you can is the correct financial move. Do not let the scoring algorithm distract you from what is important: your actual money.
