Understanding Equated Monthly Installments (EMI)
An Equated Monthly Installment (EMI) is a fixed payment amount made by a borrower to a lender at a specified date each calendar month. EMIs are applied to both interest and principal each month so that over a specified number of years, the loan is paid off in full.

Whether you're applying for a Home Loan, Car Loan, or Personal Loan, predicting your monthly outflow is the first step in solid financial planning.
The Amortization Formula
The mathematical formula used to calculate an EMI is standard across the banking industry, including Union Bank:
E = P × r × (1 + r)ⁿ / ((1 + r)ⁿ - 1)
- E is the EMI (Equated Monthly Installment)
- P is the Principal Loan Amount
- r is the monthly interest rate (Annual Rate / 12 / 100)
- n is the loan tenure in months
In the early years of a long-term loan (like a 20-year home loan), a large portion of the EMI goes towards paying the interest, while a smaller portion pays down the principal. This ratio gradually reverses over time.
Factors that Affect Your EMI
- Loan Amount (Principal): The total amount you borrow. A higher principal directly increases the EMI. Making a larger down payment reduces the principal and lowers your EMI.
- Interest Rate: The cost of borrowing the money. Home loans typically have the lowest rates, followed by car loans, with personal loans having the highest rates. Even a 0.5% reduction can save you lakhs of rupees over the life of a home loan.
- Loan Tenure: The time given to repay the loan. A longer tenure reduces your monthly EMI, making it easier to afford, but increases the total amount of interest you will pay overall.
