How Overdrafts Work
When a transaction hits your account while your balance is insufficient, your bank makes a choice: pay it and charge an overdraft fee, or decline it and possibly charge an NSF fee. Which outcome you get depends on the type of transaction and whether you have opted into overdraft coverage.
- Debit card and ATM transactions: Federal Regulation E requires your bank to get your affirmative consent before covering these transactions and charging a fee. If you have not opted in — or if you opt out — your debit card is simply declined when funds are insufficient. No fee, just a declined transaction.
- Checks and ACH payments: The opt-in requirement does not apply to checks or automated payments like bill pay. The bank may pay or return these at its own discretion, and its overdraft or NSF fee policy applies regardless of your debit card opt-in status.
- Stacking fees: Most banks can charge multiple overdraft fees in a single day — one per covered transaction. Five transactions on a low-balance day can mean five separate fees.
Your Options for Reducing or Eliminating Overdraft Fees
1. Opt Out of Debit Card and ATM Overdraft Coverage
The simplest action is to opt out of debit and ATM overdraft coverage. With opt-out in place, your card is declined when you lack sufficient funds instead of the bank covering the transaction and charging you. A declined card is inconvenient but free. Contact your bank through your mobile app, online settings, or by phone — federal law requires your bank to honor opt-out requests promptly, and you can change your decision at any time.
2. Link Your Checking Account to a Savings Account
Many banks offer overdraft transfer protection that automatically moves funds from a linked savings account to cover a shortfall. The transfer fee is typically $0 to $10, far less than the $35 overdraft fee it prevents. This keeps the transaction going through without the full penalty cost.
3. Use a Line of Credit for Overdraft Backup
Some banks allow you to link a line of credit or credit card as overdraft backup. When your checking account is short, the bank draws from the credit line instead. You pay interest on the borrowed amount but the per-transaction overdraft fee is typically eliminated or reduced — far cheaper than a $35 fee on a $5 shortage.
4. Switch to a Bank With No Overdraft Fees
Following sustained pressure from the CFPB, many online banks and credit unions have eliminated overdraft fees entirely — either declining transactions when funds are insufficient or allowing small negative balances at no charge. If you regularly pay overdraft fees, switching to a free checking account at a no-OD-fee institution may be the most impactful change you can make.

Practical Steps to Prevent Overdrafts
- Set up low-balance alerts: Most banks offer free email and text alerts when your balance drops below a threshold. Set it at $100 or more to give yourself a buffer before transactions process.
- Track scheduled automatic payments: Know when rent, utilities, subscriptions, and loan payments debit your account. A simple calendar note of debit dates and amounts prevents surprise shortfalls.
- Understand deposit availability: A check deposited today may not be fully available until tomorrow or the following business day. Never assume a deposit is accessible until confirmed. Our guide to deposit holds covers the federal rules in detail.
- Maintain a cushion: Treat your real minimum as $100 to $200 above zero. This absorbs timing differences between transactions and deposits. Our budget calculator can help you identify the right cushion for your spending patterns.
- Review your statement monthly: Regular review catches patterns that lead to overdrafts and reveals unauthorized transactions before they compound.
Transaction Order Can Work Against You: Many banks process large transactions before small ones in a batch, which maximizes the number of overdraft fees when a low balance is involved. Understanding that checks and ACH payments may not clear in the order you wrote or scheduled them is essential for avoiding unexpected overdrafts on days when your balance is close to zero.
When a Fee Hits: What to Do
- Call your bank immediately. Ask for a waiver. If it is your first or second overdraft in the past year, most banks will waive it as a one-time courtesy. Be direct and polite.
- Restore your balance promptly. Many banks charge extended overdraft fees if your account stays negative for more than a few days. Getting back to positive stops the clock on additional charges.
- Update your settings. Use the event as a trigger to opt out of debit overdraft coverage, set up account alerts, or link a savings account if you have not already done so.
- Compare your options. If your bank refused to waive the fee, that tells you something useful. Use it as motivation to compare credit union checking accounts and online bank checking accounts that offer better overdraft policies.
