Formula Used

The 123 Current Account Calculator uses the following formula to calculate the final account balance:

Final Balance = Initial Balance + Deposits - Withdrawals + (Initial Balance × Interest Rate × Time)

Where:

Initial Balance - The starting balance in your account
Deposits - Total amount added to the account
Withdrawals - Total amount taken out of the account
Interest Rate - Annual interest rate (as a decimal)
Time - Time period for interest calculation (1 for daily, 1/30 for monthly, 1/365 for annually)

This formula accounts for simple interest and assumes that interest is calculated on the initial balance only. For more complex interest calculations, additional factors may need to be considered.

Worked Example

Let's walk through an example to see how the calculator works. Suppose you have the following account details:

Initial Balance: $1,000
Deposits: $500
Withdrawals: $200
Interest Rate: 2% (0.02 as a decimal)
Time Period: Monthly (1/30)

Using the formula:

Final Balance = $1,000 + $500 - $200 + ($1,000 × 0.02 × 1/30)

Final Balance = $1,300 + ($1,000 × 0.000666667)

Final Balance = $1,300 + $0.67

Final Balance = $1,300.67

So, your final account balance after one month would be $1,300.67.
