Formula Explained

The interest earned in a savings account is calculated using the simple interest formula:

Interest = Principal × (Rate × Time) Final Amount = Principal + Interest

Where:

Principal is the initial amount of money.
Rate is the annual interest rate (expressed as a decimal).
Time is the number of years the money is invested.

For example, if you save $1,000 at an annual interest rate of 5% for 3 years, the interest earned would be $150, and the final amount would be $1,150.

Worked Example

Let's walk through a practical example to illustrate how the calculator works.

Example Calculation

Suppose you deposit $5,000 into a savings account with an annual interest rate of 3% for 5 years. Here's how to calculate the interest earned:

Principal = $5,000
Annual Interest Rate = 3% or 0.03
Time = 5 years

Using the formula:

Interest = 5000 × (0.03 × 5) = 5000 × 0.15 = $750 Final Amount = 5000 + 750 = $5,750

So, after 5 years, you would earn $750 in interest, bringing your total savings to $5,750.
