Calculate total interest payable on your loan with our comprehensive interest calculator. Compare simple vs compound interest and make informed financial decisions.
Understanding the difference between simple and compound interest is crucial for making informed borrowing decisions.
Simple interest is calculated only on the principal amount. The formula is:
This means you pay the same amount of interest each period based solely on your original loan amount.
Compound interest is calculated on the principal plus accumulated interest. The formula is:
With compound interest, you pay interest on interest, which causes your debt to grow faster over time.
Growth Rate: Compound interest grows exponentially while simple interest grows linearly.
Total Cost: Compound interest results in higher total interest paid compared to simple interest.
Common Usage: Most loans use compound interest, while simple interest is less common in modern lending.
When you borrow money through a loan, you pay back more than you borrowed. This extra amount is the interest, which is essentially the cost of borrowing money. Understanding how interest is calculated helps you make better financial decisions and choose the most suitable loan options.
Interest calculation depends on several factors including the principal amount (the original loan amount), the interest rate (percentage charged by the lender), and the loan tenure (duration of the loan). The type of interest calculation method—simple or compound—significantly impacts the total amount you'll repay.
Our loan interest calculator makes it easy to estimate your total interest payable. Simply enter your loan amount, annual interest rate, and loan tenure. Select whether you want to calculate the tenure in years or months, and choose between simple or compound interest calculation.
The calculator instantly shows you the total interest you'll pay, along with a detailed breakdown of your loan. This helps you compare different loan offers and understand the true cost of borrowing before you commit to a loan.
The choice between simple and compound interest can make a substantial difference to your total repayment amount. Simple interest is calculated only on the principal, making it more borrower-friendly. However, most modern loans, especially those with monthly payments, use compound interest which calculates interest on both the principal and accumulated interest.
For example, on a ₹100,000 loan at 10% annual interest for 5 years, simple interest would be ₹50,000, while compound interest (compounded annually) would be approximately ₹61,051. That's a difference of over ₹11,000, highlighting why understanding interest calculation is crucial.
To minimize the interest you pay on loans, consider making larger down payments to reduce the principal amount. Shorter loan tenures typically have lower interest rates and result in less total interest paid, though monthly payments will be higher. Additionally, making extra payments toward the principal when possible can significantly reduce your interest burden over time.
Always compare interest rates from multiple lenders and understand all fees associated with the loan. Sometimes a slightly higher interest rate with lower fees can be more economical than a lower rate with high processing fees or prepayment penalties.
