What is an Overdraft Fee?

An overdraft fee is the amount a bank charges when your account balance goes below zero. This usually happens when you make a payment without having enough funds in your account.

Banks may charge a fixed fee per transaction, a daily fee, or interest on the negative balance. Understanding these charges helps you plan your finances better and avoid extra costs.

Overdraft Fee Formula

There are different ways banks calculate overdraft fees. Below are the most common formulas used worldwide.

Flat Fee Formula

Overdraft Fee = (Number of Transactions × Fee per Transaction) + (Days × Daily Charge)

This formula is used when banks charge a fixed fee for each overdraft and an additional daily cost.

Interest-Based Formula

Overdraft Fee = (Amount × Interest Rate × Days) ÷ (365 × 100)

This method is used when banks apply interest on the overdraft amount.

Daily APR Formula

Overdraft Fee = Balance × (APR ÷ 100 ÷ 365) × Days

This is the most accurate method and is used by many modern banking systems.

Example Overdraft Fee Calculation

Let’s understand with a simple example.

Suppose you made 3 overdraft transactions and your bank charges $35 per transaction. Your account stayed negative for 2 days, and the daily fee is $5.

Overdraft Fee = (3 × 35) + (2 × 5)

Overdraft Fee = 105 + 10

Total Overdraft Fee = $115

Now let’s look at an interest-based example.

If your overdraft amount is $1,000, interest rate is 18%, and the duration is 10 days:

Overdraft Fee = (1000 × 18 × 10) ÷ (365 × 100)

Overdraft Fee ≈ $4.93

These examples show how different methods can affect the final cost.
