How to use the EMI calculator

  1. Enter the loan principal and choose a display currency.
  2. Enter the annual interest rate and tenure (toggle years or months).
  3. Optionally add a monthly prepayment to see how faster payoff changes interest.
  4. Read the monthly EMI, totals, and donut chart.
  5. Expand the amortization table for month-by-month principal, interest, and balance. Copy or reset as needed.

Formula & method

For a reducing-balance loan with monthly compounding, EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is principal, r is monthly rate (annual%/12/100), and n is months.

If the annual rate is 0%, EMI is simply principal ÷ months.

Each month, interest accrues on the remaining balance; the rest of the EMI (plus optional prepayment) reduces principal until the balance clears.

EMI = P·r·(1+r)^n / ((1+r)^n − 1), r = annualRate/12/100

Worked example

Borrow 100,000 at 10% annual for 12 months.

Monthly rate r = 0.10/12. EMI ≈ 8,791.59.

Total payment is a bit above 100,000; the difference is interest. Prepaying each month shortens the schedule and cuts interest.

Frequently asked questions

Is EMI the same worldwide?

The reducing-balance formula is common, but lenders may use different day counts, fees, or compounding. Treat results as estimates.

What does monthly prepayment do?

It adds an extra principal payment each month after the regular EMI, which usually shortens the loan and lowers total interest.

Can I switch tenure between years and months?

Yes. 2 years becomes 24 months internally; you can enter either unit.

Why is currency only for display?

The math is currency-agnostic. Formatting uses your selected code and the active locale’s number style.

Are loan details uploaded?

No. Calculations run in your browser.
