Simple Interest Formula

The formula for calculating simple interest is:

Where:

• Principal (P) - The initial amount of money
• Rate (R) - The annual interest rate (in decimal form)
• Time (T) - The time the money is invested for (in years)

The simple interest is calculated by multiplying the principal by the interest rate and the time period. The final amount is the sum of the principal and the interest earned.

How Simple Interest Works

Simple interest is calculated on the original principal amount only, without considering any previously earned interest. This means the interest is paid at a constant rate over the life of the investment.

Key characteristics of simple interest:

• Interest is calculated only on the original principal
• No compounding of interest
• Interest is paid at regular intervals (usually annually)
• Total interest is linear over time

Simple interest is common in savings accounts, certificates of deposit (CDs), and some types of loans. It's straightforward to calculate and understand, making it ideal for short-term savings.

Example Calculation

Let's say you deposit $1,000 in a savings account with an annual interest rate of 5% for 3 years. Here's how to calculate the simple interest and final amount:

In this example, you would earn $150 in interest over 3 years, resulting in a final amount of $1,150 in your savings account.

Simple vs. Compound Interest

Simple interest and compound interest are two different ways to calculate interest on savings. Here's how they compare:

Simple interest is easier to calculate and understand, while compound interest can lead to significantly higher returns over time. The choice between simple and compound interest depends on the type of financial product and your investment goals.
