Estimate monthly EMI, interest and total repayment.
About the EMI Calculator
An EMI calculator estimates the monthly payment for a loan using the principal, annual interest rate and tenure. It helps you compare repayment amounts before making a borrowing decision.
How to Use the EMI Calculator
Enter the loan amount, annual interest rate and tenure, then tap Calculate EMI. Review the monthly EMI, total interest and total repayment shown by the calculator.
How the EMI Calculator Works
The calculator uses the standard reducing-balance EMI formula: EMI = P × r × (1+r)^n ÷ ((1+r)^n−1), where P is principal, r is monthly interest rate and n is the number of monthly payments.
Example
For a ₹500,000 loan at 10% annual interest for 5 years, the estimated monthly EMI is about ₹10,624. Actual lender charges may differ.
Frequently Asked Questions
Does EMI include interest?
Yes. The EMI normally contains both principal and interest.
Can I compare different loan tenures?
Yes. Try different rates and tenures to compare estimated monthly payments and total interest.
Is the result an offer from a lender?

How to Use the Compound Interest Calculator
Enter the principal, annual rate, time period and compounding frequency, then calculate the estimate.
How the Compound Interest Calculator Works
For periodic compounding, the standard formula is A = P(1 + r/n)^(nt), where P is principal, r is annual rate as a decimal, n is compounding frequency and t is years. Interest = A − P.
Example
If ₹10,000 grows at 5% annually for 2 years with annual compounding, the estimated final amount is ₹11,025.
Frequently Asked Questions
What is compounding?
Compounding means previously credited interest becomes part of the balance used for later interest calculations.
Does more frequent compounding always change the result?
For the same nominal rate and period, changing compounding frequency can change the calculated amount.
Are real investment returns the same?
Not necessarily. Fees, taxes, changing rates and product terms can affect actual returns.
