Does an Unused Personal Line of Credit Cost You Anything?
A personal line of credit that just sits there, undrawn, feels like it should be free to keep around. Whether that assumption holds depends entirely on the fine print a particular lender attached when the account was opened.
The short answer
Some lenders charge a fee for keeping a personal line of credit open without using it, commonly labeled an inactivity fee, a maintenance fee, or an annual fee. Others charge nothing at all as long as the account stays in good standing. Because the practice isn’t universal, the only reliable way to know is to check the specific account agreement rather than assume either way.
Why an unused line can still cost something
From a lender’s perspective, extending a personal line of credit means committing to have funds ready the moment a borrower chooses to draw, not just processing a single transaction. That standing readiness has an administrative and capital cost regardless of whether it’s ever used. Some lenders build that cost entirely into the interest rate charged on whatever gets drawn; others choose to recover part of it through a separate periodic fee that applies whether or not the account is touched. Neither approach is inherently better, but they produce very different bills for someone who opens a line and rarely uses it.
What these fees can look like
- Inactivity fee. Charged after a stretch of time passes with no draws recorded on the account, often assessed annually or quarterly depending on the agreement.
- Flat annual fee. Charged every year the line stays open, independent of whether it was used, in the same spirit as some of the other fees banks attach to accounts regardless of activity.
- Fee waived by a minimum draw. Some agreements waive the charge entirely if even a small draw happens during the review period, which can change how a borrower thinks about occasional, deliberate use versus letting the account sit completely idle.
Weighing the cost against keeping the line open
An unused line can still serve a purpose. It adds to total available credit, which factors into credit utilization calculations, and it sits ready for an expense that hasn’t happened yet. Whether a periodic fee is worth paying for that readiness comes down to comparing the fee amount against what the line actually provides, and there’s no single answer, since it depends on the fee structure, the credit limit, and how likely the account is to get used at all. Someone who decides the fee outweighs the benefit has the option of closing the account, though closing a personal line of credit carries its own set of consequences worth understanding before making that call.
A practical habit
Before opening a personal line of credit, it helps to read the fee schedule specifically for inactivity or non-usage language, since this detail is easy to overlook next to the more prominent interest rate disclosure. Revisiting that same schedule periodically after the account is open, rather than assuming the terms never change, keeps the true cost of leaving the line untouched from becoming an unwelcome surprise on a statement.
