Home Loan Calculator
A home loan calculator converts loan amount, interest rate, and tenure into your exact monthly EMI. Borrow ₹50,00,000 at 8.5% for 20 years and the EMI is ₹43,391, with ₹54.14 lakh of interest over the term. Adjust rate, tenure, and down payment to see how each lever changes the monthly outgo and the total cost of the house.
Key facts
- A ₹50 lakh loan at 9% for 20 years accrues ₹57.97 lakh in interest - more than the principal itself.
- Stretching a ₹50 lakh, 8.5% loan from 15 to 25 years cuts the EMI from ₹49,237 to ₹40,261 (-18%) but lifts total interest from ₹38.63 lakh to ₹70.78 lakh (+83%).
- EMI = P x r x (1 + r)^n / ((1 + r)^n - 1), where r is the monthly rate (annual rate / 1200) and n the tenure in months.
- In month one of a ₹50 lakh EMI at 8.5% over 20 years, ₹35,417 of the ₹43,391 payment is interest and only ₹7,974 is principal.
What is the Home Loan Calculator?
A home loan is a long-term secured loan in which a bank or housing finance company funds the purchase, construction, or renovation of a property, holding that property as collateral until the final instalment is paid. Repayment happens through EMIs - equated monthly instalments - over tenures that commonly run 10 to 30 years. Each EMI bundles interest on the outstanding balance with a slice of principal, so early EMIs are interest-heavy and the loan amortizes fully by the end of the tenure.
How does the Home Loan Calculator work?
The calculator applies the standard amortization formula: EMI = P x r x (1 + r)^n / ((1 + r)^n - 1), where P is the principal, r the monthly rate (annual rate / 1200), and n the tenure in months. For ₹50 lakh at 8.5% over 240 months, r = 0.0070833 and the EMI works out to ₹43,391. Total interest is simply EMI x n minus the principal, and the month-by-month schedule splits each EMI into its interest and principal parts.
What is the Home Loan Calculator formula?
- P – principal (loan amount)
- r – monthly rate
- n – number of months

Worked example
| Scenario | $250,000 loan at 7% for 25 years |
| Calculation | 250,000 × 0.00583 × (1.00583^300) / ((1.00583^300) − 1) |
| Result | EMI ≈ $1,766/month. |

Tips & best practices
A larger down payment can drop you below LTV thresholds, lowering your rate.
Frequently asked questions
Most lenders cap the EMI at roughly 40-50% of your net monthly income after existing obligations. If you take home ₹1,00,000 and the lender allows a ₹40,000 EMI, that supports about ₹46 lakh at 8.5% over 20 years (EMI ₹43,391 per ₹50 lakh). A co-applicant's income, a longer tenure, or fewer existing loans all raise the eligible amount.
A shorter tenure costs dramatically less overall; a longer one eases monthly cash flow. On ₹50 lakh at 8.5%, moving from 15 to 25 years drops the EMI 18% (from ₹49,237 to ₹40,261) but raises total interest 83% (from ₹38.63 lakh to ₹70.78 lakh). Pick the shortest tenure whose EMI you can carry comfortably.
Prepaying is a guaranteed, risk-free return equal to your loan rate - 8.5% on an 8.5% loan. Invest instead only if you expect a reliably higher post-tax return. A practical middle path: keep an emergency fund and tax-advantaged investments running, then direct surplus lump sums at the loan, since early prepayments kill the most interest.
Floating rates are the default for most Indian home loans and are usually cheaper at the outset; they move with the lender's benchmark (typically repo-linked). Fixed rates buy payment certainty but often start higher and may carry conversion or prepayment restrictions. Note that regulators bar prepayment penalties on floating-rate loans to individual borrowers, which adds flexibility.
Typically 10-25% of the property value, because regulators cap the loan-to-value ratio - broadly up to 90% for smaller loans and around 75-80% for larger ones, with exact slabs set by the regulator and lender policy. A bigger down payment reduces the principal, the EMI, and often the rate you are quoted.
Yes, under the old tax regime: principal repayment qualifies for deduction up to ₹1.5 lakh a year under Section 80C, and interest on a self-occupied home up to ₹2 lakh a year under Section 24(b). The new regime generally drops these for self-occupied property, so compare regimes before deciding how to structure the loan.
On the outstanding balance: monthly interest = balance x annual rate / 12. For ₹50 lakh at 8.5%, the first month accrues 50,00,000 x 0.0070833 = ₹35,417 of interest, so only ₹7,974 of a ₹43,391 EMI reduces principal. This is why prepayments made in the early years save far more interest than the same amount paid later.
