How Age Affects Your Credit Score: 5 Things to Know Now

Credit scores reward patience. Payment history gets most of the attention, but how age affects your credit score is one of the quietest, most durable factors in your file. The age of your accounts — how long you have had credit, how old your oldest account is, and how long your accounts have been open on average — makes up roughly 15% of a FICO score. It is also the one factor you cannot manufacture overnight.

This guide explains what “credit age” actually means, why older accounts matter to lenders, and five things you can do right now to protect and build the length of your credit history.

What Does the Age of Your Credit Mean?

“Credit age” is not one number. Scoring models look at the age of your credit file from several angles:

• Age of your oldest account. This is the longest-running tradeline on your report — often your first credit card or student loan. It anchors the top end of your history.
• Age of your newest account. The most recently opened account shows how recently you took on new credit.
• Average age of accounts. Add up the ages of all your open (and sometimes closed) accounts and divide by the number of accounts. Every new account pulls this average down.

When lenders and scoring models talk about the “length of credit history,” they are weighing all three. A file with a 12-year-old card, a 6-year-old auto loan, and a 2-year-old card looks seasoned. A file with three accounts opened in the last eight months looks new — even if every payment was on time.

How Age Affects Your Credit Score: 5 Things to Know Now

Here is what credit age does to your score — and how to work with it instead of against it.

1. Length of Credit History Is a Standing ~15% of Your FICO Score

FICO scores are built from five categories: payment history (about 35%), amounts owed (about 30%), length of credit history (about 15%), new credit (about 10%), and credit mix (about 10%). The length piece is smaller than payment history, but it is constant — it is always working for you or against you. A long, clean history adds points on top of on-time payments; a short history caps how high a perfect payment record can carry you.

2. Older Accounts Raise Your Average — and Your Credibility

Every year an account stays open and in good standing, it gets heavier in your file’s math. An 8-year-old card with no late payments is strong evidence that you can manage credit across cycles, jobs, and emergencies. This is why older accounts matter: they are proof of consistency, and consistency is exactly what scoring models are designed to measure. If you are curious about the other ingredients, see what a FICO score is and how it is built.

3. Closing an Old Account Can Work Against You

Closing your oldest credit card does not erase its history immediately — closed accounts in good standing can stay on your report for up to 10 years — but it does remove that account from the active mix, and once it eventually falls off, your average age and oldest-account age can drop. Closing a card can also raise your credit utilization by shrinking your total available limit. If you are weighing this decision, read our breakdown of how closing a credit card affects your score before you call the issuer.

4. Every New Account Temporarily Lowers Your Average Age

Opening a new card or loan adds a zero-month-old account to the math, which pulls down the average age of your file, and it usually adds a hard inquiry. Neither is catastrophic — new credit is only about 10% of the score — but opening several accounts in a short window stacks the effect. Space out applications, and only open credit you actually need. Our guide to how many credit cards you should have covers how to find the right number.

5. Credit Age Cannot Be Rushed — Only Protected

There is no legitimate service that can add years of age to your credit file. Age comes from time: keeping accounts open, keeping them current, and letting history accumulate. This is good news if you already have older accounts — the asset you have is one your competitors (other applicants) cannot buy. And if you are just starting out, every month that passes is working in your favor. The fastest legitimate shortcut is becoming an authorized user on a seasoned account, which can lend you some of that age immediately.

How Much Can Older Accounts Actually Help?

Credit age is a supporting factor, not a rescue tool. Here is a realistic way to think about its impact:

• On a thin file, age is huge. If you have one or two accounts, adding a seasoned authorized-user card or simply letting your accounts mature can produce visible score movement within a year.
• On a thick file, age is polish. If you already have a long, clean history, account age is the difference between good and excellent — not between bad and good.
• Age amplifies good behavior. A 10-year-old account with perfect payments is powerful. A 10-year-old account with recent late payments is not. Age works best as a multiplier for on-time payments and low balances.

Keep your utilization low on those older cards — a small recurring charge with autopay is enough to keep them active. Our credit utilization ratio guide shows how balances and limits interact with your score.

How to Protect and Build Your Credit Age

1. Keep your oldest accounts open. Unless a card has an annual fee you cannot justify, keep it alive with a small recurring purchase. Downgrading to a no-fee version of the same card is better than closing it.
2. Use old cards lightly and automatically. A forgotten card can be closed by the issuer for inactivity, which is one of the most common ways people accidentally lose account age.
3. Limit new applications. Each application typically triggers a hard credit inquiry, and each new account resets part of your average age. Apply for credit on purpose, not on impulse.
4. Become an authorized user strategically. Being added to a trusted family member’s old, clean card can bring its age and payment history into your file. Make sure the issuer reports authorized-user activity to the bureaus.
5. Start now, even if you are starting small. A credit builder loan or a secured card opened today becomes a five-year-old account in five years. The best time to plant the account is now.

What Older Accounts Cannot Do

• They cannot erase negative items. Late payments, collections, and charge-offs are scored separately. A long history helps your score, but it does not delete accurate negative information. If you are dealing with collections, here is what paying off collections does to your score.
• They cannot fix reporting errors. A misreported account age or a mixed file works against you no matter how old the account is. Errors should be disputed — our credit repair services team reviews reports for exactly these problems.
• They cannot substitute for on-time payments. One late payment on an old account hurts more than the account’s age helps. Protect the payment record first.

5 Things to Know Right Now

1. Account age is roughly 15% of your FICO score — smaller than payment history, but always in play.
2. Your oldest account and your average account age both matter. Protect the first; watch the second before opening new credit.
3. Closing old cards can cost you — in average age, in available credit, and in utilization.
4. Age cannot be bought or added overnight. Anyone promising otherwise is selling a shortcut that does not exist.
5. Time is on your side. Every month your accounts stay open and current, your file gets stronger.

Frequently Asked Questions

How fast does account age improve my credit score?
Gradually. Account age accrues month by month, and its score impact builds over years rather than weeks. The most noticeable early gains come from keeping balances low and payments on time while your accounts mature.

Do closed accounts still count toward my credit age?
Closed accounts in good standing generally remain on your credit report for up to 10 years and can continue to contribute to your history while they are there. Once they drop off, your average age can fall — which is why keeping old accounts open is usually the better move.

Does the age of my oldest account matter more than my average age?
Both are considered. The oldest account shows the depth of your experience, while the average age reflects your overall profile. Protecting the oldest account and avoiding a cluster of new accounts keeps both numbers healthy.
