EMI Calculator
Calculate the Equated Monthly Installment (EMI) for any home loan, car loan, or personal loan using the reducing-balance method.
How to use this emi calculator
- 1Enter the loan principal — the amount you are borrowing.
- 2Enter the annual interest rate from your lender.
- 3Enter the tenure in months — 60 months = 5 years, 240 months = 20 years.
- 4The EMI is the fixed monthly payment that covers both principal and interest.
- 5Compare shorter and longer tenures to see the payment vs. total interest trade-off.
How it's calculated
EMI = P × r × (1+r)^n ÷ [(1+r)^n − 1]. Where r = monthly rate (annual ÷ 12), n = months.
About the EMI Calculator
The EMI (Equated Monthly Installment) is the standard repayment structure for consumer loans globally. Unlike simple interest loans that require lump-sum repayment, EMIs break the total repayment obligation into equal monthly amounts, making large loans manageable through predictable cash flow planning.
EMI front-loads interest payments. In the early months of a loan, most of each EMI goes toward interest with only a small portion reducing the principal. In the final months, the reverse is true. This is the natural consequence of calculating interest on a declining balance — the large early balance generates more interest than the small late balance. An amortization schedule, which breaks down the principal and interest components of each EMI, makes this pattern visible.
For large long-tenure loans like home loans, the total interest paid can exceed the principal significantly. On a $500,000 home loan at 9% for 20 years, total EMIs amount to approximately $900,000 — $400,000 in interest above the original principal. This is not unusual and does not mean the loan is a bad decision — it reflects the cost of accessing a $500,000 asset immediately rather than saving for 20+ years. But it underscores why extra principal payments are so valuable in the early years of a large long-term loan.
Frequently asked questions
What is the difference between flat rate and reducing balance EMI?
Flat rate interest calculates interest on the original principal for the entire loan term, regardless of repayments. Reducing balance (also called declining balance) calculates interest only on the outstanding principal, which decreases with each EMI payment. A 10% flat rate is approximately equivalent to an 18% reducing balance rate — the flat rate is nearly double the effective cost. Most modern bank loans use reducing balance, which is what this calculator computes. Always ask your lender which method they use, and convert flat rates to reducing balance for comparison.
Can I reduce my EMI by prepaying part of my loan?
Yes. When you make a partial prepayment (also called part-payment or lump-sum payment), the lender typically applies the entire amount to principal. This reduces your outstanding balance, which reduces the interest component of all future EMIs. Most lenders then either reduce the EMI amount (keeping the tenure same) or keep the EMI the same but shorten the tenure. Shortening the tenure saves more total interest. Check whether your loan has prepayment penalties — many fixed-rate loans charge 2–4% of the prepaid amount, which can negate some of the interest savings.
What happens if I miss an EMI payment?
Missing an EMI payment triggers several consequences: a late payment fee (typically 1–2% of the EMI amount per month), penal interest on the overdue amount (often 2–3% per annum above your loan rate), and a negative mark on your credit report after 30 days of non-payment. If payments are missed for 3+ consecutive months, most lenders classify the loan as a Non-Performing Asset (NPA) and may initiate recovery proceedings. Always contact your lender before missing a payment — many offer EMI moratorium or restructuring options for borrowers facing temporary financial difficulty.
