On Jan. 8, your account was charged $30.00 for an overdraft fee. Why did that happen? It was time for the monthly fee you pay to maintain your account. You spent more than what was in your account. You went over the limit of transactions per month. You wrote three checks that month and you have to pay a $10 fee for each one.

Answer 1

The overdraft fee of $30.00 occurred because you spent more than what was in your account. When your account balance went below zero due to your spending, the bank charged you the overdraft fee for covering that shortfall.
