Formula Used

Bank Account Balance Formula

The calculator uses the following formula to calculate your account balance:

Final Balance = Starting Balance + Deposits - Withdrawals + Interest Earned

Where Interest Earned is calculated as:

Interest Earned = (Starting Balance + Deposits - Withdrawals) × (Interest Rate / 100) × Time Period

The time period is calculated based on your selection (daily, monthly, or annually).

Worked Example

Let's calculate a bank account balance with the following details:

Starting Balance: $1,000
Deposits: $500
Withdrawals: $200
Interest Rate: 2% annually
Time Period: 1 year

First, calculate the intermediate balance:

$1,000 (starting) + $500 (deposits) - $200 (withdrawals) = $1,300

Then calculate the interest earned:

$1,300 × (2% / 100) × 1 year = $26

Finally, add the interest to get the final balance:

$1,300 + $26 = $1,326

The calculator would show a final balance of $1,326.
