EMI Calculator — monthly loan payment for any loan, any currency
Work out your monthly EMI, total interest, and a full year-by-year amortisation schedule for home, vehicle, personal, or education loans. Uses the standard reducing-balance formula, supports ten currencies, and runs entirely in your browser.
How it works
An Equated Monthly Instalment, or EMI, is the fixed amount you repay to the lender each month. Every instalment is split into two parts — interest on the outstanding balance, and principal that pays the loan down. The interest portion is large at the start and shrinks each month as the balance falls, which is why the schedule is called a reducing balance.
The closed-form expression for a fixed-rate, fully-amortising EMI is a result that drops out of the present-value-of-annuity identity in corporate finance:
EMI = P × r × (1 + r)^n
─────────────────
(1 + r)^n − 1Here P is the principal (loan amount), r is the monthly periodic rate (the annual rate divided by 12), and n is the total number of monthly instalments. The result is in the same currency as the principal — the formula has no currency baked into it.
The amortisation schedule is then built one month at a time. For each month, the interest portion is opening balance × r, the principal portion is EMI − interest portion, and the closing balance is opening balance − principal portion. The calculator aggregates these monthly steps into a year-by-year table and snaps any sub-unit floating-point residual onto the final principal payment so the schedule closes at exactly zero.
Every EMI shown on this page is cross-checked against the present-value-of-annuity identity P = EMI × (1 − (1 + r)^−n) / r. Re-deriving the principal from the computed EMI should return the original loan amount; if it does not, the “PV-identity verified” badge in the calculator card will not light up.
