Loan EMI Calculator

An EMI (Equated Monthly Instalment) is the fixed amount you pay your lender every month until the loan is fully repaid. Each EMI has two parts: the principal (the amount you borrowed) and the interest (the cost of borrowing). Because the EMI never changes, it is what makes long loans feel manageable — and it is also what hides how much interest you actually end up paying.

How the EMI formula works

The formula is:

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

• P is the loan amount (principal)
• r is the monthly interest rate — your annual rate divided by 12 and by 100
• n is the total number of monthly payments (years × 12)

Early in the loan, most of your EMI goes toward interest. Over time the balance falls, so a larger share of the EMI pays down the principal. The amortization table below the calculator shows this month by month: you can see exactly how much of each payment is interest and how much reduces what you owe.

Worked example

For a ₹50,00,000 home loan at 8.5% for 20 years:

• Monthly rate r = 8.5 / 12 / 100 = 0.00708
• n = 20 × 12 = 240 months
• EMI = 50,00,000 × 0.00708 × (1.00708)²⁴⁰ / ((1.00708)²⁴⁰ − 1) ≈ ₹43,391

Over 240 months you pay roughly ₹43,391 × 240 = ₹1,04,13,879 in total, of which about ₹54,13,879 is interest. The interest alone exceeds the loan amount — which is exactly why prepaying early saves so much.

The early-payment trap explained

In year one of this loan, roughly ₹35,100 of each ₹43,391 EMI is interest. Only about ₹8,300 touches your principal each month. The split gradually inverts — around the 12th year interest falls below principal, and by year 15 about ₹27,100 of each EMI repays principal against only ₹16,200 of interest. This "back-loaded" structure means the first decade is the worst time to be paying slowly — additional prepayment early in the loan kills far more interest than the same money would later.

Fixed vs floating rates

Home loans in India usually carry a floating rate (tied to an external benchmark like the repo rate). Your EMI can reset when rates move. When rates fall, lenders often offer a choice: reduce EMI or reduce tenure — tenure reduction keeps your EMI constant and saves more interest in the long run. Fixed personal loans keep the EMI steady for the term, which is why personal and car loans are easier to budget.

Eligibility and how much you can borrow

Lenders typically approve borrowing where the EMI does not exceed 40–50% of monthly income (the FOIR rule). With a monthly income of ₹1,00,000, many lenders keep a ₹43,391 home-loan EMI within range, but a higher EMI means a smaller loan. Before applying, check your EMI budget against your total monthly outflow — debt-to-income ratio tools formalise the same logic.

Tips

• A slightly lower rate or shorter tenure cuts the total interest dramatically. Try the sliders.
• Making one extra EMI per year or small monthly prepayments shortens the loan years and saves lakhs in interest.
• Compare offers using the same amount and tenure — the lowest rate wins, but watch for processing fees and prepayment penalties.
• Keep some flexibility: longer tenure with occasional prepayment can beat a rigid short-tenure plan when income varies.
