What is Simple Interest?
Simple interest is the interest charged only on the original loan amount (principal) throughout the loan tenure. Unlike compound interest, it does not calculate interest on previously accumulated interest.
Simple Interest Formula
The formula used to calculate simple interest is:
Simple Interest = Principal × Interest Rate × Time
Where:
Principal = Loan amount
Interest Rate = Annual rate of interest
Time = Loan duration in years
This straightforward formula makes it easy to estimate the total borrowing cost.
How Does a Simple Interest Calculator Work?
A simple interest calculator automates the calculation process by asking you to enter:
Principal Amount
Enter the total amount you plan to borrow.
Interest Rate
Input the annual interest rate offered by the lender.
Loan Tenure
Select the repayment period in months or years.
The calculator instantly displays:
1- Total interest payable
2-Total repayment amount
3-Estimated loan cost
This eliminates manual calculations and reduces the chances of errors.
