Loan EMI Calculation Formula Explained with Examples
Understand how Equated Monthly Installments (EMI) work, the mathematical formula behind loan interest, and how to reduce total interest.
Understanding your Equated Monthly Installment (EMI) before taking a home loan, car loan, or personal loan is essential for healthy financial planning. An EMI consists of both principal repayment and interest charges spread evenly across your loan tenure.
The EMI Calculation Formula
Loan EMIs are calculated using the standard mathematical formula:
EMI = [P x R x (1+R)^N] / [(1+R)^N - 1]Where:
- P = Principal Loan Amount
- R = Monthly Interest Rate (Annual Rate divided by 12 divided by 100)
- N = Loan Tenure in Months
Reducing Total Interest Outflow
Because EMI payments are heavily front-loaded toward interest repayment in the early years of a loan, making prepayments early in your loan tenure significantly reduces total interest paid.
