Understanding emi calculator
An EMI contains both interest and principal. The interest portion is usually larger early in a reducing-balance loan because more principal remains outstanding. Compare a shorter tenure with the same principal and rate to see the tradeoff between monthly affordability and total interest cost.
Formula and calculation method
EMI = P × i / [1 − (1+i)^−n], with monthly rate i = nominal annual rate/12. At zero interest EMI = P/n. Extra principal reduces the remaining payoff term.
Fixed-rate EMI with equal monthly periods. Fees, insurance, prepayment penalties and changing rates are excluded. Car and home tools use the same standard annuity method with topic-specific guidance; they are not lender offers.
How to use emi calculator
- Set Amount financed. The example below uses 1000000.
- Set Nominal annual loan interest (%). The example below uses 9.
- Set Loan tenure (months). The example below uses 120.
- Set Extra monthly principal payment. The example below uses 0.
- Select Calculate to update the result. Reset restores the illustrated inputs. Copy, print or download your own result if you need a record.

Factors affecting your result
Fixed-rate EMI with equal monthly periods. Fees, insurance, prepayment penalties and changing rates are excluded. Car and home tools use the same standard annuity method with topic-specific guidance; they are not lender offers.
Changing amount financed changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
Frequently asked questions
How does the emi calculator work?
EMI = P × i / [1 − (1+i)^−n], with monthly rate i = nominal annual rate/12. At zero interest EMI = P/n. Extra principal reduces the remaining payoff term.
What inputs does EMI Calculator need?
Enter amount financed, nominal annual loan interest (%), loan tenure (months), extra monthly principal payment. Read the unit labels; percentages are entered as ordinary percentages, not decimal fractions.
How should I interpret the emi calculator result?
Fixed-rate EMI with equal monthly periods. Fees, insurance, prepayment penalties and changing rates are excluded. Car and home tools use the same standard annuity method with topic-specific guidance; they are not lender offers.
