EMI Calculator
Calculate EMI, total interest and amortization schedule for any reducing balance loan in India. Free EMI calculator with year by year principal and interest split.
An EMI, or Equated Monthly Instalment, is the fixed monthly payment a borrower makes to a lender on a reducing balance loan. Each EMI is split into two parts. A portion goes toward interest on the outstanding balance, the rest reduces the principal. Early EMIs are mostly interest. Later EMIs are mostly principal. The EMI calculator on this page computes the monthly figure, the total interest you will pay over the loan, and a year by year breakdown so you can see exactly how the split shifts.
Inputs
Why use the EMI Calculator
Loan officers usually quote two numbers, the rate and the tenure. The number that matters most to your monthly cash flow is the EMI, and the number that matters most to your total cost is the interest. Both depend on the loan amount, the rate and the tenure in nonlinear ways. Doubling the tenure does not halve the EMI but it nearly doubles the total interest. The EMI calculator lets you experiment with all three sliders before you sign a loan agreement.
Benefits at a glance
Accurate reducing balance EMI
Uses the standard reducing balance formula, the same one every Indian bank applies to home, car, personal and education loans. The output matches what your lender's amortization sheet will show.
Total interest exposed
The calculator does not just give the EMI, it shows the total interest paid over the life of the loan. For a 20 year home loan, the total interest often exceeds the original principal, which is the kind of number that changes how borrowers feel about prepayment.
Year by year amortization chart
The chart breaks each year into principal paid and interest paid, stacked. The split flips around the midpoint of the tenure, which is usually surprising the first time you see it.
Works for any reducing balance loan
The same formula applies to every reducing balance loan in India. Use this calculator for a generic loan, or jump to the home, car, personal or education loan calculators for category specific defaults.
How to use the EMI Calculator
- 1
Enter the loan amount
The principal you are borrowing. Use the actual sanctioned amount, after any margin money or down payment.
- 2
Enter the interest rate
The annual rate offered by the lender. For floating rate loans, use the current rate as a starting point and rerun the calculator if the rate is reset by the RBI's repo cycle.
- 3
Enter the tenure in years
Loan tenure. Five years for a personal loan, 5 to 7 for a car loan, 15 to 25 for a home loan. The tenure dramatically affects total interest, so try a few values to find your sweet spot.
- 4
Read the EMI and total interest
The EMI is your monthly outflow. The total interest is the lifetime cost above the principal. Use both to judge whether the loan is comfortable.
Frequently asked questions
What is the EMI formula?
EMI equals P times r times (1 plus r) raised to n, divided by ((1 plus r) raised to n minus 1). Here P is the loan amount, r is the monthly interest rate (annual rate divided by 12 and divided by 100) and n is the number of monthly instalments. Every Indian bank uses this formula for reducing balance loans.
Why is the EMI mostly interest in the early years?
Because interest is calculated on the outstanding balance. In the first month the balance is the full loan amount, so most of the EMI goes to interest. As the principal reduces, the interest portion shrinks and the principal portion grows. By the last few years of a long tenure loan, almost the entire EMI is principal repayment.
Should I take a longer or shorter tenure?
A longer tenure means a lower monthly EMI but more total interest paid. A shorter tenure means a higher EMI but a meaningfully lower total cost. The right answer balances monthly affordability against the total amount of interest you are willing to pay. A common rule of thumb is to keep total EMI commitments at 40 to 50 percent of net monthly income.
What is the difference between fixed rate and floating rate EMI?
A fixed rate loan keeps the EMI constant for the full tenure, regardless of market interest rate movements. A floating rate loan changes the EMI (or the tenure) when the lender's benchmark (often linked to the RBI repo rate) is revised. Most home loans in India are floating rate. Most car and personal loans are fixed rate.
Can I prepay my loan and reduce the EMI?
Yes. Prepayment reduces the outstanding principal. Most banks then ask whether you want to keep the EMI the same and shorten the tenure, or keep the tenure the same and lower the EMI. Shortening the tenure usually saves more interest. The loan prepayment calculator on this site shows the exact savings for any prepayment scenario.
Is EMI the same as instalment for a credit card?
No. Credit card EMI on a single transaction is typically a flat interest scheme rather than reducing balance, which makes the effective rate higher than the quoted rate. Read the fine print before converting a card transaction to an EMI plan.
Are there charges other than interest on a loan?
Yes. Most loans carry processing fees (0.5 to 2 percent of the loan amount), legal and valuation charges (for home loans), GST on the processing fee, and sometimes annual maintenance charges. These are not included in the EMI but they add to the total cost. Ask the lender for the All In Cost or Annual Percentage Rate (APR) for a complete picture.
Final word
The EMI calculator is the most used tool on any financial calculator site, and for good reason. A loan is a multi year commitment that often dwarfs every other monthly outflow. Run the calculator before you sign, run it again before you accept any tenure extension, and run it once more before you say no to a prepayment. The numbers usually argue more strongly than your intuition does.
