Does Length of Credit History Affect Insurance Score
Yes, a longer credit history usually helps your insurance score, but it's one factor among several, not the whole picture.
What length of history actually changes
- Older accounts help Insurers see a long-held account as a sign of stability. If you have an old credit card or loan, keep it open even if you rarely use it.
- New accounts drag briefly Opening new credit resets your average age of accounts for a while. If you don't need new credit right now, wait until after you've shopped for insurance.
- Thin files score differently If you're newer to credit or had accounts close during a divorce or bankruptcy, your file may look thin. Ask insurers how they treat limited history, since some have specific rules for it.
- Other factors still matter more Payment history and amounts owed usually carry more weight than age alone. Focus your energy there first if you're working to improve your score.
- State rules vary Some states limit or ban the use of credit-based insurance scores entirely. Check your state's rules before assuming this applies to you.
A driver with a short credit history after a divorce
You went through a divorce two years ago and most of the joint accounts were closed as part of the settlement. What used to be ten years of combined credit history on paper now looks like two years under your name alone. When you shopped for car insurance, one quote came back higher than you expected, even though your driving record was spotless.
You called and asked directly how they weighed credit history length against other factors. The agent explained that your short file was a factor, but your on-time payments on the accounts you did have open worked in your favor. You also found an insurer in your state that used a different mix of factors, weighing history length less heavily. You kept your oldest remaining account open, avoided opening anything new before your renewal, and switched to the insurer with the better mix. Your rate came down and has stayed steady since.
Will my insurance score improve just by waiting?
Yes, somewhat. As your current accounts simply get older, your average account age grows and that part of your score tends to improve on its own, without you doing anything else.
But waiting alone won't fix a low score if other factors are working against you. If you're also carrying high balances or have missed payments, those will outweigh the slow improvement from age. The fastest path is usually to let your existing accounts age undisturbed while you pay down balances and pay on time. If you're rebuilding after a bankruptcy or a period of medical debt, expect the history piece to improve gradually, over a longer stretch than the other factors.
Now you understand how history length factors in, compare quotes to find the insurer whose scoring suits you.
Should you open a new account before you shop for insurance
If you do
Opening a new card or loan right before shopping could lower your average account age and briefly drag your score down. Your quote might come back higher than if you'd waited. If you already applied, check your current quote and compare it against a fresh one in a few months.
If you don't
Leaving your credit accounts alone keeps your average age steady, which protects the history portion of your score right when insurers are checking it. Your quotes should reflect your actual standing. Once you've locked in a policy, you can make other credit moves without affecting that rate.
Does closing an old credit card hurt my insurance score?
Yes, it can. Closing your oldest account removes it from the average age calculation and can shorten your effective credit history overnight. This matters most if that account was your longest-held one. If you're thinking about closing a card, check whether it has an annual fee you're trying to avoid, and weigh that against the potential hit to your score. Keeping it open with occasional small use often costs less than the score drop from closing it.
How often do insurers recheck my credit history length?
It depends on your insurer and your state, so check your policy terms. Some insurers only check at the start of a policy and leave your rate alone until renewal. Others re-pull your credit at each renewal, meaning your account age and overall score get reassessed regularly. If your state restricts how often insurers can use credit for existing customers, that limits how much a renewal recheck can affect you. Ask your insurer directly how their renewal process works.
Can an authorized user account help my credit history length?
Yes, in many cases. If you're added as an authorized user on someone else's older account, that account's age can sometimes count toward your own history, depending on how the scoring model treats it. This can help if your own accounts are new or thin. It won't work the same way everywhere, and insurance scoring models don't always treat authorized user accounts the same as credit lenders do, so confirm with the insurer how they weigh it before relying on it.
Your credit history quietly works for you, so protect it by keeping old accounts open instead of new ones.
