Month Payment Principal Interest Extra Balance

How is EMI Calculated?

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

Where P is the loan amount, r is the periodic interest rate (adjusted for compound and payback frequency), and n is the total number of payments. Every payment covers the month's interest first, then reduces the principal. That is why the interest portion decreases each month while the principal portion grows.

EMI Calculator FAQ

What is an EMI?
EMI (Equated Monthly Installment) is the fixed amount you pay your lender every month until the loan is fully repaid. It includes both the principal and the interest portion.
Does the EMI amount stay the same every month?
For a fixed-rate loan, yes. The total EMI stays constant, but within each payment the interest portion decreases over time while the principal portion increases. This is shown in the amortization schedule above.
How can I reduce my total interest?
Make extra monthly or one-time payments. Every extra dollar reduces your principal directly, which cuts future interest and shortens the loan term.

What is an EMI and how does it work?

EMI stands for Equated Monthly Instalment — the fixed amount you pay your lender every month until the loan is fully repaid. Each EMI has two parts: the principal (the money you borrowed) and the interest (the lender's fee). Early in the loan, most of your EMI goes toward interest; as the loan matures, the principal share grows. This calculator uses the standard amortization formula to give you the exact EMI, total interest and a complete month-by-month repayment schedule.

The EMI formula explained

EMI = 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 total number of monthly payments (tenure in years × 12).

For example, a $20,00,000 loan at 8.5% for 20 years gives r = 0.7083% and n = 240. Plugging into the formula produces an EMI of about $17,350.

Banks add processing fees and GST on top, so your effective cost is slightly higher than the pure EMI shown here.

Why the interest component is highest at the start

Interest is charged on the outstanding balance, which is largest at the beginning. In month 1 of the example above, interest is about $14,167 and principal only $3,183.

By year 15 the balance has shrunk so much that the principal share of each EMI exceeds the interest share. This is called an amortizing loan.

Because interest is front-loaded, paying extra in the early years reduces total interest dramatically — completing a few extra payments in year 1 can save years of payments later.

How banks calculate your eligibility

Most lenders use the FOIR (Fixed Obligation to Income Ratio) method: your total EMIs, including this new loan, should stay below 40–50% of your net monthly income.

Some use the multiplier approach — loan amount = annual income × 3 to 4.5, depending on your age and the lender.

Your credit score (CIBIL) heavily influences both approval and the interest rate offered. A score above 750 usually secures the best rates.

How to use this calculator

  1. Enter the loan amount you wish to borrow in the first field.
  2. Type the annual interest rate offered by your lender (for example 8.5).
  3. Choose the loan tenure in years.
  4. The EMI, total interest and amortization schedule update instantly as you type.
  5. Use the sliders (if visible) to explore how different tenures change your EMI.

Pro tips

  • A longer tenure lowers your EMI but more than doubles total interest — always compare total cost, not just the monthly number.
  • A higher credit score (750+) typically gets you 0.25–0.50% lower interest, saving tens of thousands over the life of the loan.
  • Making one extra EMI per year can reduce a 20-year loan by roughly 3–4 years.

Frequently asked questions

How is EMI calculated?
EMI is calculated using the formula P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1), where P is the principal, r the monthly interest rate, and n the number of months. This formula gives a constant monthly payment that fully repays the loan by the end of the tenure.
What is a good EMI-to-income ratio?
Financial advisors recommend keeping all your EMIs below 40–50% of your net monthly income. If your EMI alone exceeds this, lenders will usually reject or reduce the loan amount.
Can I prepay my loan?
Yes. Most lenders allow part-prepayment after a lock-in period. Since interest is front-loaded, prepaying early saves the most interest. Some banks charge a prepayment penalty, so check your loan agreement.
What is the difference between fixed and floating interest rates?
A fixed rate stays constant for the entire loan or a lock-in period. A floating rate moves with the repo rate / MCLR. Floating loans are usually cheaper but carry uncertainty about future EMIs.
Does the EMI change if I increase my tenure?
Increasing the tenure reduces the EMI but increases the total interest paid because you pay interest for a longer period. Use the sliders to see this trade-off visually.
