Use the Interest Investment Calculator to determine how much interest you can earn on your investments over time. By entering the principal amount, interest rate, and time period, you can easily calculate both simple and compound interest.
Understanding Interest
Interest is the cost of borrowing money or the return on investment for saving money. It is typically expressed as a percentage of the principal amount. There are two main types of interest: simple interest and compound interest.
What is Simple Interest?
Simple interest is calculated only on the principal amount, or the original amount of money that was invested or borrowed. The formula for calculating simple interest is:
Simple Interest = Principal × Rate × Time
Where:
- Principal: The initial amount of money invested or borrowed.
- Rate: The annual interest rate (in percentage).
- Time: The time period for which the money is invested or borrowed (in years).
What is Compound Interest?
Compound interest is calculated on the initial principal and also on the accumulated interest from previous periods. This means that you earn interest on your interest. The formula for calculating compound interest is:
Compound Interest = Principal × (1 + Rate / 100) ^ Time - Principal
Where:
- Principal: The initial amount of money invested or borrowed.
- Rate: The annual interest rate (in percentage).
- Time: The time period for which the money is invested or borrowed (in years).

Example Calculation
Let’s say you invest $1,000 at an annual interest rate of 5% for 3 years. Using the simple interest formula:
Simple Interest = 1000 × 5 × 3 / 100 = $150
So, after 3 years, you would earn $150 in simple interest, making your total amount $1,150.
For compound interest, if you use the same principal and rate but compound annually:
Compound Interest = 1000 × (1 + 0.05) ^ 3 - 1000 = $157.63
Thus, after 3 years, you would earn approximately $157.63 in compound interest, resulting in a total of $1,157.63.
