Final answer:
ATM fees are usually the lowest, followed by maintenance fees, with overdraft fees being the highest of the three.
Step-by-step explanation:
The correct order of average fee amounts from least to greatest is typically ATM fees, maintenance fees, and then overdraft fees.
ATM fees are generally the lowest and may range from a few cents to a few dollars when using an ATM outside of your bank's network.
Maintenance fees are charged monthly for keeping an account open and may vary depending on the balance and the type of account.
Overdraft fees are typically the highest and can occur each time a transaction exceeds the account's available balance.
