EMI Calculator

Math

Compute the equated monthly installment, total interest, and a year-by-year breakdown for a loan from principal, rate, and tenure

Enter a loan principal, annual interest rate, and tenure in years or months to get the fixed Equated Monthly Installment back immediately, using the same reducing-balance formula lenders use for EMI schedules on personal loans, auto loans, and mortgages. Instead of a full month-by-month table, results are grouped into a year-by-year breakdown of principal versus interest paid, which is how EMI figures are typically presented to borrowers and makes it easy to see how the balance shrinks over the life of the loan. A 0% interest rate is handled as a straight-line split rather than dividing by zero, useful for interest-free installment plans. Everything runs from the standard formula with no live rate feed and no data sent anywhere.

How to use EMI Calculator

  • 1.Enter the loan principal, annual interest rate, and tenure, choosing whether the tenure is in years or months.
  • 2.Read off the EMI, total interest, and total amount payable for the loan.
  • 3.Expand the yearly breakdown to see how much of each year's payments go to principal versus interest as the balance shrinks.

Frequently asked questions

How is this different from the Loan / Mortgage Calculator?
Both use the identical reducing-balance amortization formula. This tool accepts tenure in years or months and reports a year-by-year principal/interest breakdown instead of a full month-by-month schedule, matching how EMI figures are usually presented to borrowers.
Does this account for processing fees or insurance add-ons?
No. It computes the standard EMI from principal, rate, and tenure only, the same core math used before fees, insurance, or taxes are layered on top by a lender.
Can I use this for a 0% interest loan?
Yes, a 0% rate is handled as a straight-line split of principal across the tenure instead of running the compound-interest formula, so it won't divide by zero or error out.
Is my loan data sent anywhere?
No, the calculation runs entirely in your browser, REST call, or SDK function locally. Nothing is transmitted to a third party or stored.
