Interest Rate = (Interest Earned / Principal Amount) × 100

Where:

Interest Earned is the total interest you've earned on your savings.
Principal Amount is the initial amount of money you deposited.

The result is expressed as a percentage, representing the annualized interest rate if the time period is not already annual.

Worked Example

Let's say you deposited $1,000 in a savings account and earned $50 in interest over one year. Here's how to calculate your interest rate:

Example Calculation

Interest Rate = ($50 / $1,000) × 100 = 5%

In this example, your savings interest rate is 5%. This means you earned 5% of your principal amount as interest over the year.
