The short answer: home loan EMI is calculated from the loan amount, monthly interest rate and loan tenure in months. The standard reducing-balance formula estimates a fixed monthly instalment that repays both interest and principal over the selected tenure.
Use the Home Loan EMI Calculator to replace the example below with your own loan amount, rate and tenure.
Meaning of loan amount, rate and tenure
Loan amount is the principal borrowed. Interest rate is entered as an annual percentage, then converted to a monthly rate. Loan tenure is the repayment period, usually expressed in years on this site and converted into months for the formula.
The estimate is illustrative. It does not fetch current bank rates or model processing fees, insurance products, prepayments, moratoriums or lender-specific rounding.
EMI formula
The reducing-balance EMI formula is:
EMI = P x R x (1 + R)^N / ((1 + R)^N - 1)
Where:
Pis principal loan amountRis monthly interest rateNis loan tenure in months
If the interest rate is 0 percent, EMI is simply principal divided by tenure in months.
Worked example
Using this site’s tested India EMI utility:
| Input or result | Value |
|---|---|
| Loan amount | ₹50,00,000 |
| Illustrative interest rate | 8.50 percent p.a. |
| Tenure | 20 years |
| Monthly EMI | ₹43,391 |
| Total Interest Payable | ₹54,13,879 |
| Total Amount Payable | ₹1,04,13,879 |
The monthly EMI is rounded for display. The calculation keeps internal precision before formatting.
How inputs affect EMI
A higher loan amount increases EMI. A higher interest rate increases EMI and total interest payable. A longer tenure usually lowers EMI because repayment is spread across more months, but it can increase total interest.
