If you’re wondering why your credit age is so low, the answer is almost always one of three things: you haven’t had credit open long enough, you recently added accounts that pulled the average down, or an old account disappeared from your report. Length of credit history accounts for roughly 15% of your FICO score and around 20% of your VantageScore, so it’s a meaningful piece of the number lenders see.1myFICO. How Are FICO Scores Calculated The good news is that most of the causes are either fixable or will correct themselves with time, once you understand what the scoring models are actually measuring.
How Credit Age Gets Calculated
Scoring models take the number of months since each account on your report was opened, add those numbers together, and divide by the total number of accounts. One account that’s ten years old and another that’s two years old gives you an average age of six years.2myFICO. How Is the Length of Your Credit History Calculated That average is the number driving the “length of credit history” portion of your score, along with the age of your oldest account and the age of your newest one.
FICO and VantageScore handle this slightly differently. FICO keeps closed accounts in the average age calculation for as long as they remain on your report, so a credit card you closed years ago still counts.2myFICO. How Is the Length of Your Credit History Calculated VantageScore may exclude some closed accounts from its calculation, which is why your two scores can show different credit ages on the same day.
You Haven’t Had Credit Long Enough
The simplest reason is also the most common one. To generate a FICO score at all, you need at least one account that’s been open for six months and reported to a bureau within the past six months.3myFICO. What Are the Minimum Requirements for a FICO Score Clearing that threshold doesn’t give you a seasoned profile. It just gets you on the board.
If you opened your first credit card recently, there’s no shortcut. Credit age rewards patience, not strategy. The clock started when your first account opened, and every month that passes adds to the average. In the meantime, keeping that first account open and in good standing does more for your long-term score than almost anything else you could do.
You Opened New Accounts Recently
Every new credit card, auto loan, or personal loan drops a zero-month account into the average. The math moves fast. Say you have three accounts averaging eight years old. Open one new card and the average falls to six years overnight. Open two more and you’re at four. Your old accounts didn’t change. The denominator just grew.
Holiday store-card signups and chasing credit card sign-up bonuses in a short window hit the hardest, because each new account adds another zero to the equation. The effect is temporary in the sense that those new accounts age like any other, but “temporary” here means months or years, not weeks.
Rent and Utility Reporting Services
Services that report your rent or utility payments to the bureaus can help if you have a thin file. If you already have established credit, each new reported tradeline enters your average the same way a credit card would. A seven-year average takes the same hit from a brand-new rent tradeline as it would from a new credit card. For someone with solid credit already, the tradeoff often isn’t worth it.
Timing Before a Mortgage
This dilution matters most right before a mortgage application. Underwriters look closely at your report, and a sudden drop in average age combined with fresh hard inquiries can raise concerns. The safer approach is to avoid opening any new credit, including car loans and credit card refinancing, for at least six months before you apply.4Experian.

An Old Account Dropped Off Your Report
The Fair Credit Reporting Act limits how long negative information can stay on your report: seven years for most derogatory items and ten years for bankruptcy.5Office of the Law Revision Counsel. 15 USC 1681c – Requirements Relating to Information Contained in Consumer Reports No federal law caps how long positive information can stay, but the major bureaus follow their own policies, and the standard practice is to remove closed accounts in good standing after ten years.6Experian. Closed Accounts and Your Credit History
That ten-year drop-off is where silent damage happens. A credit card you closed in good standing a decade ago has been quietly propping up your average all along. When it falls off, the younger accounts become the entire basis for your credit age. Nothing in your behavior changed, but the number drops.
Paying Off an Installment Loan
Paying off a car loan, student loan, or personal loan closes the account. Under FICO, that closed loan keeps aging in your average as long as it stays on your report. Under some VantageScore versions, it may stop contributing sooner. Either way, once it eventually falls off, the age benefit disappears. If that loan was one of your oldest accounts, the impact can be real. It’s one of the frustrating paradoxes of credit scoring: doing the responsible thing can temporarily lower your score.
You Lost Authorized User Status
Being an authorized user on someone else’s long-held card, often a parent’s or spouse’s, is a common way to borrow credit history. The account’s full age typically appears on your report, and a card that’s been open twenty years can make your profile look far more seasoned than it is.
When the primary cardholder removes you or closes the card, that borrowed history leaves your report. For someone whose own accounts are only a few years old, losing a single twenty-year authorized user tradeline can cut the average dramatically.
There’s a nuance worth knowing. Current FICO models appear to handle authorized user accounts differently than many people assume. While those accounts still show up on your report and influence your score through factors like payment history, there’s evidence that FICO doesn’t count authorized user accounts toward the length-of-credit-history calculation specifically. Removal may affect VantageScore more than FICO on the age factor. If you lost authorized user status and saw your score drop, credit age may not be the main cause.
Errors on Your Credit Report
Sometimes the data itself is wrong. Creditors occasionally report the wrong opening date, most often when an account is upgraded or converted to a new product and the creditor records the conversion date instead of the original one. That can shave years off your history for no legitimate reason.
Identity theft is another common culprit. A thief who opens several accounts in your name in a short period dumps multiple zero-month tradelines onto your report, dragging the average down fast. A different error, called a mixed file, happens when a bureau accidentally merges your records with someone who has a similar name or Social Security number. If that person’s accounts are newer than yours, your average takes the hit.
How to Dispute Errors
You have the right under the FCRA to dispute incomplete or inaccurate information on your report. The bureau must investigate and correct or remove unverifiable information, generally within 30 days.7Federal Trade Commission. A Summary of Your Rights Under the Fair Credit Reporting Act When you file, include copies (not originals) of documents that support your claim, such as account statements showing the correct opening date or correspondence from the lender.8Federal Trade Commission. Disputing Errors on Your Credit Reports You can file disputes with Equifax, Experian, or TransUnion through their websites, by mail, or by phone.
For identity theft, also file a report at IdentityTheft.gov and place a fraud alert or credit freeze on your files. Once fraudulent accounts come off through the dispute process, your legitimate average age is restored.
A Business Credit Card on Your Personal Report
If you carry a business credit card, it may be showing up on your personal credit report depending on the issuer. Chase, Capital One, and Discover are among the issuers that report business card activity to the consumer bureaus. Bank of America, Citi, and Wells Fargo generally don’t when the account is current.
A business card that reports to your personal file adds a tradeline to your average age calculation. If it’s newer than your other accounts, it drags the average down like any new personal account would. If you want to protect your personal credit age, choosing a business card from an issuer that doesn’t report to consumer bureaus keeps your personal average untouched. On the other hand, if you’ve held a business card for years with an issuer that does report, closing it or switching could remove a seasoned account from your profile.
What Actually Builds Credit Age Over Time
Credit age is the most patience-dependent part of your score. Utilization you can fix in one billing cycle. Average account age only grows with time. The most effective strategy is also the least exciting: keep your oldest accounts open and active. Even light use, a small purchase every few months, prevents the issuer from closing the card for inactivity.
Resist closing old cards you no longer use, especially no-fee ones. That card sitting in a drawer is doing real work for your score just by existing. If it does carry an annual fee, call the issuer and ask to downgrade to a no-fee version of the same card. Most will do this without closing the account, which preserves the original opening date.
When you do need new credit, space applications out instead of opening several at once. One new account barely dents a five-year average. Three at the same time can knock years off it. And before signing up for rent reporting, utility reporting, or a store card to save 10% on a purchase, weigh the short-term perk against the dilution it creates. For thin files, the tradeoff is usually worth it. For established credit, it rarely is.
