The Formula

The simple interest formula is:

Interest = Principal × Rate × Time

Where:

Principal is your account balance
Rate is the annual interest rate (expressed as a decimal)
Time is the number of years the money is invested

The total amount is calculated as:

Total Amount = Principal + Interest

Worked Example

Let's say you have $5,000 in your 123 Current Account with an annual interest rate of 2%. You want to know how much interest you'll earn in 3 years.

Step-by-Step Calculation

Principal (P) = $5,000
Annual Interest Rate (r) = 2% = 0.02
Time (t) = 3 years
Interest (I) = P × r × t = $5,000 × 0.02 × 3 = $300
Total Amount = P + I = $5,000 + $300 = $5,300

Using the calculator, you would enter $5,000 as the account balance, 2% as the interest rate, and 3 years as the time period. The calculator would then display $300 as the interest earned and $5,300 as the total amount.

Remember: This is a simple interest calculation. If your account offers compound interest, the actual amount would be higher.
