Simple Interest Calculator – Calculate Interest in Seconds

When it comes to basic financial planning, sometimes you don’t need complex formulas or detailed breakdowns. That’s where a Simple Interest Calculator comes in handy.

Whether you’re a student, professional, or small business owner, this tool helps you understand your finances in seconds. For deeper insights, check out our guide on Simple Interest vs Compound Interest to see how both methods impact your savings and loans.

What Is a Simple Interest Calculator?

A Simple Interest Calculator is a financial tool that determines the cost of borrowing or the return on savings when interest is applied to the principal alone. It requires just three inputs:

• Principal: the initial amount of money borrowed or invested.
• Rate of Interest (%): annual rate applied to the principal.
• Time (years): the loan or investment period.

This calculator instantly provides you with the total interest amount and total repayment (principal + interest).

The Formula Behind Simple Interest

Our calculator uses the universally accepted simple interest formula:

SI=P×R×T

Where:

• SI = Simple Interest
• P = Principal (the original amount)
• R = Annual Rate of Interest (in decimal form, e.g., 7% = 0.07)
• T = Time (in years)

The total repayment amount is then:

Total Repayment=P+SI

Example of Simple Interest Calculation

Suppose you borrow $10,000 at a 7% annual interest rate for 3 years.

So, the total interest will be $2,100.

Total Repayment=10000+2100=12,100

This means after 3 years, you’ll repay $12,100 in total.
