Average Age of Credit: Why Old Accounts Matter

Average age of credit is the total time you've held all your credit accounts divided by the number of accounts you have. Here's what that means in real life.

If you have three credit cards—one opened 15 years ago, one opened 8 years ago, and one opened 2 years ago—your average age is (15 + 8 + 2) ÷ 3 = 8.3 years. That's your number.

Credit bureaus track this for a reason. Your average age tells lenders how long you've been managing credit. Someone with a 10-year average age has proven they can keep accounts active and pay on time for a decade. Someone with a 1-year average looks like they're just starting out—or like they close accounts frequently.

Your oldest account always counts. So does your newest. When you open a new credit card or take out a loan, it immediately pulls down your average. If your average is 7 years and you open a new card, it might drop to 6.5 years overnight. That's temporary—it improves every single month as the new account ages.

The key: credit bureaus care about length of credit history. The longer your history, the better. This isn't about perfect payments (though those help). It's about showing that you've had credit responsibility for years, not months.

Average age of credit accounts for 30% of your credit score according to Fair Isaac Company's FICO model. That's the same weight as your payment history.

Here's what 30% means in dollars and rates. If your credit score is 650 (fair), moving it to 720 (good) saves you roughly $100–$200 per month on a $300,000 mortgage. Some of that gap is payment history. Some of it is average age.

Lenders use average age to predict risk. A 45-year-old with a 1-year average age credit history is a bigger risk than a 25-year-old with an 8-year average. Why? The older borrower might be new to credit or have closed many accounts. The younger borrower has proven they manage credit long-term.

Here's a real example. Sarah applied for a car loan at 22 with a 3-year average credit age. She was approved at 7.2% APR. Her friend Marcus, also 22, applied with a 0.5-year average (new to credit) and was offered 9.8% APR on the same car. The difference: $45 more per month, or $2,160 over a 4-year loan. That's the price of age.

Closing old accounts destroys your average age. Close a 12-year-old card and your average drops instantly—sometimes by 2–3 years if you don't have many other accounts. That drop can cost you 50–100 points on your credit score, which translates to higher rates on everything you borrow next.

Banks know this. That's why they work hard to keep you from closing old accounts. Your age is their reassurance that you're not a flight risk.

When you apply for a mortgage, car loan, credit card, or personal loan, the lender pulls your credit report and calculates your average age in seconds. They compare it to your payment history, debt-to-income ratio, and credit mix. If your average age is below 3 years, red flags go up. Below 2 years, you're almost certainly getting a higher rate—or a rejection.

Mortgage lenders are especially strict. They want to see an average age of at least 5 years before offering you the best rates. With a 4-year average, you'll get approved but at a higher rate. With a 2-year average on a $400,000 mortgage, you might pay an extra 0.75% APR—that's roughly $3,000 per year in interest.

Credit card issuers look at average age to decide your credit limit and APR. If you have a 10-year average, a new card issuer might offer you $15,000 at 16% APR. If you have a 1-year average, the same issuer offers $500 at 24% APR. The difference isn't your income. It's your credit age.

Auto lenders run similar calculations. A 35-year-old with a 12-year credit average gets better rates than a 35-year-old with a 3-year average, even if both have perfect recent payment history.

Here's what lenders don't tell you: they also look at your oldest account specifically. If your oldest account is 20 years old, that tells them you've been trusted by lenders for two decades. That's a stronger signal than average age alone. They want to see stability. Closing that 20-year-old account doesn't just hurt your average—it removes your strongest proof of long-term creditworthiness.

Secured credit card companies, credit repair firms, and subprime lenders also use age to decide whether to work with you. The companies that help people rebuild credit (legitimately, not the scams) want to see some credit age already there, because it shows you've had credit before and managed it at some level.

Closing a credit account is one of the fastest ways to tank your credit age. Here's what happens.

When you close an account, the credit bureau doesn't delete it immediately. But it stops counting toward your average age calculation in the same way. If you have 5 open accounts with an average age of 8 years, and you close the oldest one (15 years old), your new average drops to about 6.5 years. That's a 1.5-year drop overnight.

Here's a real impact: Marcus had 5 cards averaging 6 years old. His credit score was 680. He paid off his oldest card (12 years old) and closed it to "stop temptation." His average age dropped to 5 years. His credit score fell to 630. Six months later, he applied for a car loan and was rejected for "insufficient credit history"—even though he'd had credit for 12 years. The age calculation overwrote his actual history.

Closing newer accounts hurts less (you lose less age), but it still hurts. Closing a 2-year-old card when you only have 4 cards total drops your average by 0.5 years—not huge, but measurable.

The worst scenario: closing multiple accounts in a short period. If you pay off three cards in 6 months and close them, your average age collapses. Your score can drop 100+ points. Lenders see this and assume you're in financial trouble or unreliable.

Closed accounts stay on your credit report for 10 years (if they're positive) or 7 years (if they're negative). But the moment you close them, they stop helping your average age calculation the same way. The account is still there. Lenders can still see it. But it's no longer active, which weakens the signal.

Here's the hard truth: never close an old account just because you paid it off. Keep it open. Use it once a year if you have to (buy gas, pay immediately). The $0 balance doesn't hurt you—it helps you. The account's age is working in your favor every single day.

Loan closures (auto loans, personal loans, mortgages) count too. When you pay off a car loan, keep it on your report. Don't request early removal. Let it age. Installment loans that are paid off in good standing boost your credit mix and age.

You can't make old accounts appear if you don't have them. But you can stop destroying the ones you have and start growing your average age today.

Step 1: Don't close old accounts. This is the most important step. If you have a credit card from 10 years ago, even if it has a $0 balance, keep it open. Set a small recurring charge on it (like a streaming service) and pay it off every month. The account stays active, the age stays counted, and your credit score benefits.

Step 2: Check for accounts you forgot about. Log into your credit report (free at annualcreditreport.com, required by the Fair Credit Reporting Act). Look for old accounts you opened and then ignored. Some might still be open. A 15-year-old account you forgot about is helping your score right now. Don't close it.

Step 3: Add yourself as an authorized user on old accounts held by family members. If your parent or spouse has a card opened 20 years ago with perfect payment history, ask to be added as an authorized user. Their account's age gets added to your credit file. This can instantly boost your average age by 5+ years if you don't have much history. (This works only if the account holder has good payment history—don't ask someone with late payments.)

Step 4: Don't apply for new credit unless you really need it. Every new account drops your average age. You need new credit sometimes (mortgage, car, emergency), but don't open three new cards in one month. Space out applications. The damage from a new account is temporary—it improves every month—but why rush it?

Step 5: Use old accounts, even minimally. An active account ages better than an inactive one. Charge something small every quarter (a coffee, a fill-up) and pay it off. This keeps the account active and signals to the lender that you still trust them.

Step 6: Understand your credit report timeline. Accounts stay on your report for 7–10 years. A closed positive account stays longer. A charge-off or collection account stays 7 years from the date of first delinquency. Don't assume old negative items vanish—but do know when they're scheduled to drop off. A collections account closing in 2 months should not derail your strategy.

Building average age is a waiting game, but it's free. Every month that passes, every old account you keep active, makes your credit stronger.

Average age improves slowly, but it does improve. Here's what to expect.

Months 1–6: If you just opened a new account, your average age drops immediately. You'll see the drop reflected in your credit score within 30–45 days. Don't panic. This is temporary.

Months 6–12: If you don't open any new accounts and keep your old ones active, your average age starts to recover. Each month adds to your account ages. After 6 months, your average age is 0.5 years higher than it was when you opened that new account. The damage is partially healed.

Year 1: A new account is now 1 year old. If you had 5 accounts averaging 5 years, and one is now 1 year old, your new average is about 4.2 years. You've recovered most of the damage.

Year 2: Your new account is 2 years old. Your average age is now roughly equal to where it was before you opened it. The damage is fully healed (assuming you didn't open more accounts).

Year 3–5: If you keep all accounts open and active, your average age climbs. It goes up by 1 year every year (because all your accounts age, and none are new). By year 5, you've regained the loss and then some.

Year 7+: An old account that was negative (charge-off, collection) falls off your report. If that was pulling down your average age, your average jumps up.

Year 10: Really old negative accounts fall off completely. Your average age reaches maximum benefit from those old positive accounts (they've now been on your report for 10 years).

Here's a real timeline. James opened a credit card in 2016 (10 years ago). His average age was 7 years. In 2024, he applied for a mortgage and panicked—he'd opened three new cards that year for the rate bonuses, dropping his average to 5.5 years. His mortgage application was approved but at a higher rate. He closed the new cards (mistake—would have hurt more). Fast forward to 2026: his average is back to 6 years, and his original 2016 card is now 10 years old. In 2026, his average age is strong enough that refinancing is an option.

The lesson: don't obsess over average age month-to-month. Focus on the 2–3 year timeline. That's when the damage from new accounts fades and the benefits from old accounts compound.

You already know closing old accounts is bad. Here are the other mistakes people make.

Mistake 1: Opening multiple new accounts in a short period. Applying for 3 credit cards, a car loan, and a personal loan in 6 months tanks your average age. Each application shows up as a hard inquiry on your credit report. Each approval adds a new account. Your average age can drop 3–5 years over 6 months. Spread out applications by at least 6 months. Better: a year apart.

Mistake 2: Confusing "paid off" with "close." You don't have to close an account after paying it off. In fact, don't. A paid-off account with a $0 balance helps your credit score and average age. Closing it destroys both benefits. Thousands of people pay off credit cards and immediately call to close them, tanking their scores in the process.

Mistake 3: Closing accounts to "simplify" after debt payoff. You paid off $50,000 in debt across 4 cards. Congratulations. Don't close those 4 cards. Close 0 cards. Keep the 4 open with $0 balances. Your credit score thanks you. Your average age thanks you.

Mistake 4: Letting old accounts become inactive for years. A 12-year-old card you never use is still helping your age. But if you don't use it for 3+ years, the creditor might close it (for inactivity). Then it no longer helps your age the same way. Solution: use it once a year, even if it's just a small charge.

Mistake 5: Believing the credit card company when they say "close this account, it will help you." Credit card companies sometimes suggest closing accounts to "reduce temptation" or "manage your accounts." They're looking out for themselves, not you. Ignore them. Keep the account open.

Mistake 6: Not checking your credit report for old accounts you forgot about. You opened a card in college and never used it. It's still reporting. That account is now 15 years old. You don't remember it, but it's working for you. Don't discover it by accident when you close it thinking it doesn't exist. Check your credit report annually (free at annualcreditreport.com) and find these hidden helpers.

Mistake 7: Thinking average age doesn't matter if your payment history is perfect. It matters. Even with perfect recent payments, a short average age means higher interest rates and possible loan rejections. Average age is 30% of your score—same weight as payment history. Don't ignore it.

The pattern: old accounts help you. New accounts hurt you (temporarily). Closed accounts remove the help. The fix is to stop closing accounts and stop opening new ones unless you really need to.

Here's exactly what to do, starting today.

Days 1–7 (This Week): Get your free credit report from annualcreditreport.com. You're allowed one free report per year from each bureau (Equifax, Experian, TransUnion). Get all three. Read through them. Write down every account and when it was opened. You're looking for old accounts you might have forgotten about. Don't close anything yet. Just read.

Days 8–14: For each account you found, decide: keep it open or close it? The rule: if it's old (5+ years) and has a positive history (no late payments), keep it open forever. Don't close it. If it's new (less than 2 years) or has a negative history (collections, charge-off), you can consider closing it after the negative item falls off your report (7 years from first delinquency).

List all accounts you're keeping. Find one card per account and use it once (buy gas, pay a bill, order something online). Pay it off immediately. This keeps the account active.

Days 15–30: If you have family members with older accounts and good payment history, ask if you can be added as an authorized user. This is free for them and costs you nothing. Their old account gets added to your credit file, boosting your average age. This is the fastest way to improve age if you don't have much history yourself.

Also: make a note of when you last opened a credit account. Calculate how long until you can open the next one (6–12 months from the last opening). Put a reminder in your phone. Don't apply for credit just because you got approved. Apply only when you have a real need (mortgage, car, debt consolidation).

Days 31–60: Make sure your old accounts are active. Use one card every 30 days (doesn't matter what—just pay immediately). Set reminders in your phone if you tend to forget about accounts.

Review your credit report again. Check for any errors (wrong account opening dates, accounts that should be closed but show as open). If you find errors, dispute them through annualcreditreport.com or directly with the credit bureau. The Fair Credit Reporting Act (FCRA) requires bureaus to correct inaccurate information within 30 days.

Days 61–90: Check your credit score. Use a free tool (Credit Karma, Discover Credit Scorecard, your bank's credit score tool). Write down your score. If you took action to keep old accounts open and not open new ones, your score should hold steady or improve slightly over these 90 days. The real improvement comes over months 4–12 as old accounts age and new accounts improve in age.

Make a commitment: no new credit applications for the next 6 months unless absolutely necessary (home or car purchase). Each month that passes without a new application helps your average age.

Schedule a reminder in your phone to check this plan again in 6 months. By then, any new accounts will be 6 months older, and your average age will have recovered significantly.
