Loan EMI Calculator
Calculate your monthly installment (EMI), total interest outflow, and year-by-year repayment amortization schedule for Home Loans, Personal Loans, and Car Loans in India.
Loan Details
Adjust amount, interest rate and tenure to recalculate your monthly EMI instantly.
Add an extra monthly prepayment to see how much interest and tenure you save.
In the early years of a long-term loan (like Home Loans), up to 70% of each EMI goes towards paying interest rather than the principal. Prepaying even small lump-sums during the first 5 years drastically reduces your overall interest burden.

How Bank Loan EMI Works: Formula, Math & Prepayment Secrets
When you borrow money from a bank in India—whether for a flat in Mumbai, a personal emergency, or a new vehicle—the bank splits your debt into regular monthly payments called an Equated Monthly Installment (EMI).
While the monthly amount remains constant throughout the loan tenure, the internal composition of each EMI changes dynamically every single month. In the early stages of a loan, up to 70% to 80% of your EMI goes purely toward interest, while only a small slice reduces the actual principal. Toward the end of your tenure, this ratio flips.
The Standard Loan EMI Mathematical Formula
EMI = [P × r × (1 + r)ⁿ] ÷ [(1 + r)ⁿ - 1]
Some non-banking financial companies (NBFCs) and personal loan agents quote a "Flat Rate" of 7% or 8%. In a flat rate loan, interest is charged on the original principal throughout the loan tenure without factoring in your monthly repayments. A flat rate of 8% is actually equivalent to a Reducing Balance Rate of nearly 14.5% to 15%! Always ask the lender for the reducing balance rate (or Annual Percentage Rate - APR) before signing.
How 1 Extra EMI Per Year Can Save You ₹8 Lakhs
Consider a Home Loan of ₹40,00,000 at 8.5% interest for 20 years:
- Your standard monthly EMI is ₹34,713.
- Over 20 years, your total interest paid to the bank will be ₹43,31,114—more than the actual loan itself!
- If you make just 1 extra EMI prepayment each year (₹34,713), your loan tenure drops from 20 years to approximately 16.5 years, and you save over ₹8,50,000 in interest!
Frequently Asked Questions on Loan EMI
What is an Equated Monthly Installment (EMI)?
An Equated Monthly Installment (EMI) is a fixed payment amount made by a borrower to a lender on a specified calendar date each month. Each EMI payment is apportioned toward both the principal loan amount and the accrued interest over the loan tenure.
How is loan EMI calculated mathematically?
Loan EMI is calculated using the reducing balance formula: EMI = [P x r x (1 + r)^n] / [(1 + r)^n - 1], where P is the Principal loan amount, r is the monthly interest rate (Annual interest rate / 12 / 100), and n is the loan tenure in total months.
What is the difference between a Reducing Balance Rate and a Flat Interest Rate?
In a reducing balance loan, interest is calculated only on the remaining outstanding loan principal each month. In a flat interest rate loan, interest is calculated on the entire original principal for the full tenure, making the effective interest rate almost double what is advertised.
Can I reduce my loan EMI or tenure through prepayment?
Yes. Making prepayments or part-payments reduces your outstanding principal balance directly. You can choose to either reduce your monthly EMI while keeping the tenure constant, or reduce your remaining tenure while keeping the EMI constant (which saves maximum interest).
Are there foreclosure charges on home loans in India?
As per Reserve Bank of India (RBI) guidelines, banks and housing finance companies (HFCs) are strictly prohibited from charging any foreclosure or prepayment penalties on floating-rate individual home loans.
