About EMI Calculator

The EMI Calculator helps you calculate your monthly loan installment (EMI) along with total interest payable, total repayment amount, processing fees, and complete amortization schedule.

This tool provides detailed payment breakdowns, yearly summaries, and downloadable reports to help you plan your loan repayment accurately.

What Is EMI?

EMI stands for Equated Monthly Installment.

It is the fixed amount you pay every month to repay a loan. Each EMI includes:

• A principal component (repayment of the borrowed amount)

• An interest component (cost of borrowing)

Over time, the interest portion decreases and the principal portion increases.

• Monthly EMI

• Total interest payable

EMI Calculation Method

The calculator uses the standard EMI formula:

• EMI calculated using compound interest formula

• Special handling for zero interest scenario

It also adjusts the final month to prevent rounding errors, ensuring the remaining balance reaches exactly zero.
