Credit Union Overdraft Fees

Credit union overdraft fees occur when a transaction exceeds the available balance in a member’s checking account. If the credit union chooses to approve the transaction despite insufficient funds, the account may become overdrawn and an overdraft fee may be charged.

Overdraft policies vary between credit unions, but many institutions offer overdraft protection options that can help members avoid or reduce these fees.

What Is an Overdraft Fee?

An overdraft fee is a charge applied when a financial institution processes a payment that exceeds the account balance. This may happen with debit card purchases, ATM withdrawals, automatic payments, or checks.


Instead of declining the transaction, the credit union may temporarily cover the shortfall and then charge a fee for the overdraft.

Typical Credit Union Overdraft Fees

Overdraft fees vary by institution, but credit union fees are often lower than those charged by large banks.


  • Typical overdraft fee: $20 to $35 per transaction
  • Daily overdraft limits may apply
  • Some credit unions cap the number of overdraft fees per day

Members should review their credit union’s account agreement to understand specific fee amounts and policies.

How Credit Union Overdraft Protection Works

Many credit unions offer overdraft protection programs that link a checking account to another account. When a transaction exceeds the available balance, funds may automatically transfer to cover the payment.

  • Transfers from savings accounts
  • Overdraft lines of credit
  • Linked checking accounts

These programs may reduce or eliminate overdraft fees depending on the credit union’s policies.

Transactions That Can Cause Overdraft Fees

Several types of transactions can cause a checking account to become overdrawn.


  • Debit card purchases
  • ATM withdrawals
  • Automatic bill payments
  • Checks

ATM withdrawals may also involve additional charges depending on the machine used. Learn more in our guide to credit union ATM fees.

How to Avoid Credit Union Overdraft Fees

Credit union members can reduce the risk of overdraft fees by monitoring account balances and using available account alerts.

  • Set up balance alerts through mobile banking
  • Link a savings account for overdraft protection
  • Track automatic payments and subscriptions
  • Maintain a small buffer in checking accounts

Many credit unions offer mobile tools that help members track balances and transactions in real time.

How Credit Unions Compare to Banks

Credit union overdraft policies are often designed to be more member-friendly than traditional bank policies. Because credit unions are member-owned institutions, many attempt to limit excessive fees or offer flexible repayment options.
