Will Closing My Oldest Credit Card Really Wreck My Score?

By The Penny Plan Editorial Team Published July 13, 2026 5 min read

A drawer somewhere has a credit card that hasn’t been used in years, the one that opened up a credit file in the first place. It carries an annual fee, or it just feels like clutter, and the urge to finally close it runs straight into a warning heard a hundred times: never close your oldest card. Is that actually true, or is it more nuanced than that?

The short answer

Closing the oldest account on a credit file can lower the average age of accounts over time, which is one factor that contributes to a credit score, but it’s rarely the dramatic hit people fear, especially if other accounts remain open and in good standing. The size of the effect depends heavily on how many other accounts exist, how old they are, and how much available credit disappears along with the closed card.

Why account age matters at all

Length of credit history is one of several factors that make up a credit score, alongside things like payment history and credit utilization, which each carry more weight. When an account closes, it doesn’t vanish from a credit report immediately. Closed accounts in good standing generally stay on a report for up to ten years, continuing to count toward average age during that window. The real shift in average age tends to show up later, once that account eventually drops off the report entirely.

The other factor worth watching

When keeping it open makes more sense on paper

An unused card with no annual fee generally costs nothing to leave open, which is why it’s common advice to keep an old account active rather than close it purely for tidiness. Using it for a small recurring charge occasionally can also help keep the issuer from closing it first due to inactivity, which would produce the same outcome without any choice in the matter.

What actually pushes people to close it

Annual fees, security concerns after a data breach, or just wanting fewer accounts to manage are all real reasons someone might close a card despite the credit history trade-off. It also helps to understand which of several credit scores actually matters for whatever a person is applying for next, since a temporary dip from a closed account may not affect every lender’s model the same way.

Where this leaves you

Closing an old credit card can nudge a score down, mainly through reduced available credit and, eventually, a shorter average account age, but the effect tends to be smaller and slower than the fear around it suggests. Weighing the account’s fees and usefulness against that modest, gradual impact is generally more useful than treating an old card as something that can never be closed.
