EMI Calculator
An Equated Monthly Installment (EMI) is a fixed payment amount made by a borrower to a financial institution on a specified date each calendar month. EMIs apply to home loans, car loans, education loans, and personal loans, allowing you to pay off both principal and interest over a chosen tenure.

How the Calculation Works
The EMI calculation uses the reducing-balance method formula: EMI = [P x R x (1+R)^N] / [(1+R)^N - 1], where P is the Principal loan amount, R is the monthly interest rate (Annual Rate / 12 / 100), and N is the total tenure in months.
Worked Example
Here is a step-by-step example calculation for ₹20 Lakh Home Loan for 15 Years @ 9.5% p.a.:
| Parameter | Value |
|---|---|
| Principal | ₹20,000,000 |
| Rate | 9.5% |
| Tenure | 15 Years (180 months) |
| Emi | ₹20,887 |
| Total Interest | ₹17,59,622 |
| Total Payout | ₹37,59,622 |
Scenario Analysis
Comparing different tenures, interest rates, or investment horizons:
| Scenario Label | Key Metric |
|---|---|
| 10 Year Tenure | Emi: ₹25,845, Interest: ₹11,01,417 |
| 15 Year Tenure | Emi: ₹20,887, Interest: ₹17,59,622 |
| 20 Year Tenure | Emi: ₹18,643, Interest: ₹24,74,320 |
Common Mistakes to Avoid
- Choosing longer tenure solely for lower EMI, resulting in paying more interest than principal.
- Ignoring processing fees, stamp duty, and pre-closure charges levied by banks.
- Failing to compare reducing balance interest rates against flat interest rates.
Frequently Asked Questions (FAQs)
What is the reducing balance EMI method?
In the reducing balance method, interest is calculated every month on the remaining outstanding principal balance rather than the original loan amount, lowering overall interest burden.
Does prepayment reduce loan tenure or EMI?
When making a loan prepayment, borrowers can choose either to lower their monthly EMI or keep EMI same and reduce total loan tenure. Tenure reduction yields higher interest savings.
How does interest rate change affect floating rate loans?
When the RBI changes repo rates, banks revise their Repo Rate Linked Lending Rates (RLLR), which automatically alters either your EMI amount or loan tenure.
