Interest Rate Calculator

An Interest Rate Calculator is an online tool that computes the amount of interest earned or paid on a financial transaction based on the principal/loan amount, the interest rate, and the time period. It simplifies complex interest calculations and allows you to visualize how interest can grow or impact your financial goals over time.

Our Calculator is a powerful financial tool designed to help you quickly and accurately calculate the interest earned or paid on various financial transactions. Whether you’re dealing with loans, investments, or savings, this calculator empowers you to make informed decisions by understanding the impact of interest rates on your finances.

Interest Rate Calculator Example

Example: Let’s say you lend your friend $1,000 at an annual interest rate of 5% for a period of 3 years.

Using the formula for interest rate:

Interest Rate = P * r * t


P = Principal amount/Loan Amount = $1,000

r = Annual interest rate = 5% = 0.05 (expressed as a decimal)

t = Time period in years = 3 years

Now, plug in the values:

Interest Rate = $1,000 * 0.05 * 3

Interest Rate = $1,000 * 0.15

Interest Rate = $150

So, the interest on the loan is $150. This means that after 3 years, your friend would need to repay the original $1,000 principal plus an additional $150 in interest, making the total repayment amount $1,150.
