How to Use the EMI Calculator

Using the iCalcDesk EMI calculator is straightforward. Adjust the three sliders or type values directly into the input fields:

• Loan Amount (₹): The total amount you plan to borrow — the principal. For a home loan, this is typically the property value minus your down payment.
• Interest Rate (% per annum): The annual interest rate your bank is charging. Check your loan offer letter for this figure. Home loan rates in India currently range from around 8.5% to 11% per annum.
• Loan Tenure (months): The duration over which you will repay the loan. Home loans can run up to 30 years (360 months), car loans typically 1–7 years, personal loans 1–5 years.

The calculator instantly shows your monthly EMI, total interest payable over the entire tenure, and the total amount you'll repay (principal + interest). Below the results, a month-by-month amortisation schedule shows exactly how much of each EMI goes toward principal vs interest. Use the CSV export button to download this schedule for your records.

EMI Formula — How Banks Calculate Your Instalment

Indian banks and NBFCs use the reducing-balance method (also called the diminishing balance method) to calculate EMIs. The formula is:

EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)

Where:

• P = Principal loan amount (₹)
• r = Monthly interest rate = Annual rate ÷ 12 ÷ 100
• n = Loan tenure in months

With the reducing-balance method, interest is charged only on the outstanding principal at the start of each month — not on the original loan amount. This means your interest outgo decreases every month as you repay principal, even though your EMI amount stays the same. The early months of any loan are interest-heavy; later months are principal-heavy.

Example EMI Calculation

Suppose you take a home loan of ₹50,00,000 at 9% per annum for 20 years (240 months).

• Monthly rate r = 9 ÷ 12 ÷ 100 = 0.0075
• EMI = 50,00,000 × 0.0075 × (1.0075)²⁴⁰ ÷ ((1.0075)²⁴⁰ − 1)
• Monthly EMI ≈ ₹44,986
• Total repayment = ₹44,986 × 240 = ₹1,07,96,640
• Total interest = ₹1,07,96,640 − ₹50,00,000 = ₹57,96,640

This means you pay nearly ₹58 lakh in interest alone on a ₹50 lakh loan over 20 years at 9%. Making even a single annual prepayment can dramatically reduce this total interest cost — use the amortisation schedule to see the impact.

Frequently Asked Questions

What is EMI?

EMI stands for Equated Monthly Instalment. It is the fixed amount you pay your lender every month to repay a loan. Each EMI payment consists of two components — a portion that repays the outstanding principal, and a portion that covers the interest charged for that month. The split between principal and interest changes every month, but the total EMI amount stays fixed throughout the loan tenure (for fixed-rate loans).

How is EMI calculated in India?

Indian banks use the reducing-balance method. The EMI formula is P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1), where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100), and n is the tenure in months. This calculator uses this exact formula, consistent with RBI guidelines for retail lending in India.

Does prepayment reduce my EMI or my tenure?

Most Indian lenders offer both options when you make a prepayment. Reducing tenure is generally more financially advantageous — you pay off the loan sooner and save significantly more on total interest. Reducing EMI lowers your monthly outflow, which may be preferable if you're managing tight cash flow. Some lenders charge a prepayment penalty on fixed-rate loans; floating-rate loans (most home loans in India) cannot have prepayment charges under RBI rules.

What is the difference between flat rate and reducing balance EMI?

A flat-rate EMI charges interest on the full original principal for every month of the tenure, regardless of how much you've already repaid. Reducing-balance EMI charges interest only on the remaining outstanding principal — so your effective interest cost decreases as you repay. Most Indian banks use reducing balance for home, car, and personal loans. Flat rate is common in some two-wheeler loans and older NBFC products. For the same stated interest rate, flat rate ends up being significantly more expensive in practice.

How do I reduce my home loan EMI?

There are four main levers: (1) Increase the down payment — a smaller principal means a smaller EMI; (2) Negotiate a lower interest rate — even 0.25% less on a ₹50L loan saves thousands annually; (3) Choose a longer tenure — stretching from 15 to 20 years reduces the monthly EMI, though total interest increases; (4) Make periodic prepayments — even ₹10,000 extra per year, applied to principal, can cut years off your tenure and save lakhs in interest.
