Formula used
EMI = P x r x (1+r)^n / ((1+r)^n - 1), where P is the home loan amount, r is the monthly interest rate (annual rate divided by 12 and 100), and n is the tenure in months (years x 12).
Example calculation
For a Rs 30,00,000 home loan at 8.5% for 20 years, monthly EMI is about Rs 26,035, total repayment is about Rs 62,48,400, and total interest is about Rs 32,48,400 — more than the loan amount itself.
How to use this calculator
- Enter the home loan amount you plan to borrow.
- Enter the annual interest rate from your lender's offer.
- Set the tenure in years, commonly 15 to 30 for home loans.
- Read the monthly EMI, total interest and total repayment.
- Change tenure or rate to compare scenarios before committing.
Important assumptions
- Fixed EMI over the full tenure using the reducing-balance method; floating-rate resets are not simulated.
- Processing fees, insurance, stamp duty and other charges are excluded.
- Educational estimate only. Final EMI and terms are set by your lender's sanction letter.
Common mistakes to avoid
- Choosing the longest tenure only for a lower EMI without checking total interest.
- Ignoring processing fees, insurance and stamp duty when budgeting.
- Assuming the EMI stays fixed on a floating-rate loan.
- Borrowing the maximum sanctioned amount instead of what the household budget supports.
- Not planning part-prepayments that could cut years of interest.
How is home loan EMI calculated?
Home loan EMI uses the standard reducing-balance formula EMI = P x r x (1+r)^n / ((1+r)^n - 1). Each EMI first covers the month's interest on the outstanding balance, and the remainder reduces principal. Early in the tenure most of the EMI is interest; the principal share grows over time.
- P = loan amount, r = monthly rate, n = tenure in months.
- Longer tenure lowers EMI but raises total interest sharply.
- Small rate differences compound into large cost differences over 20-30 years.
15 vs 20 vs 30 Year Home Loan: What Changes
For a Rs 30 lakh loan at 8.5%, a 15-year tenure means an EMI of about Rs 29,542 and total interest of about Rs 23.2 lakh. At 20 years, EMI drops to about Rs 26,035 but total interest rises to about Rs 32.5 lakh. At 30 years, EMI falls further to about Rs 23,067 while total interest exceeds Rs 53 lakh — more than 1.7 times the loan itself. Choose tenure by comparing total cost, not EMI alone.
Home Loan Tax Context: Section 24(b) and 80C
Under the old tax regime, interest on a self-occupied property may be deductible under Section 24(b) up to the applicable annual cap, and principal repayment may count toward the Section 80C limit. These deductions are generally not available under the default new tax regime, so compare regimes before assuming tax savings from a home loan.
- Section 24(b): interest deduction for self-occupied property, subject to cap.
- Section 80C: principal repayment within the overall 80C limit.
- Compare old vs new regime impact before counting on these benefits.
Prepayment and Floating Rates
Most Indian home loans are floating-rate. When the benchmark rate changes, lenders adjust the EMI or the remaining tenure. Part-prepayment reduces outstanding principal directly, and on floating-rate home loans to individuals, lenders generally cannot charge prepayment penalties. Even one extra EMI per year can shorten a 20-year loan meaningfully.
