About this tool

Every loan — a mortgage, a car loan, a personal loan, an education loan — works on the same mathematical formula: the Equated Monthly Instalment (EMI) is determined by your principal, annual interest rate and repayment period. Knowing your EMI before you sign lets you compare offers, stress-test your budget and negotiate from an informed position rather than discovering the number at closing.

This calculator implements the standard reducing-balance amortisation formula used by banks worldwide: each month, interest is charged on the remaining principal, so early payments are mostly interest and later ones are mostly principal. The key output is the monthly payment — but equally important is the total interest, which tells you the real cost of borrowing. A longer tenure lowers the monthly payment but substantially increases the total interest paid; the interest breakdown shows this trade-off visually.

Works for any amount and any currency — eight major currencies are selectable, and the calculation is currency-agnostic. Use it for a home loan in pounds, a car loan in dollars, or a personal loan in rupees: the formula is identical. Results should be treated as accurate estimates — actual lender figures may vary by rounding method, processing fees and other charges.

Frequently asked questions

What is EMI?

EMI stands for Equated Monthly Instalment — the fixed amount you pay every month for the life of the loan. It covers both principal repayment and interest, with the proportion shifting toward principal over time.

What does 'reducing balance' mean?

Interest is charged only on the outstanding principal, not the original loan amount. As you repay, the principal reduces, so the interest portion of each EMI shrinks and the principal portion grows — this is standard for all modern personal and home loans.

Why does a longer tenure increase total cost?

A longer tenure means more months of interest accruing on the outstanding balance. While monthly payments are lower, you pay more interest in total. The interest breakdown bar shows this ratio for your specific inputs.

Does this work for mortgages?

Yes — a mortgage is a reducing-balance amortising loan, which is exactly what this calculator models. Enter the mortgage amount, annual rate and term in years for an accurate monthly payment estimate.
