EMI for ₹50 Lakh Home Loan: 15, 20 and 30-Year Comparison (2026)

A ₹50 lakh home loan is the most common ticket size for an Indian homebuyer in 2026. The question every borrower wants answered before signing the agreement: how much EMI will I actually pay, and how much extra is the interest going to cost me over the life of the loan? The Short Answer At an indicative rate of 8.5% per annum, the EMI on a ₹50,00,000 home loan works out to approximately: - 15 years (180 months): ₹49,237 per month — total interest ₹38,62,612 - 20 years (240 months): ₹43,391 per month — total interest ₹54,13,879 - 25 years (300 months): ₹40,261 per month — total interest ₹70,78,236 - 30 years (360 months): ₹38,446 per month — total interest ₹88,40,613 The 30-year tenure looks attractive because the monthly EMI is the lowest, but it costs you almost 1.8 times the principal in interest. The 15-year tenure costs the least overall but demands a much higher monthly outflow. How EMI Is Calculated EMI uses the standard reducing-balance formula: EMI = [P × R × (1+R)^N] / [(1+R)^N − 1] where P is the principal (₹50,00,000), R is the monthly interest rate (8.5 / 12 / 100 = 0.00708), and N is the tenure in months. Each EMI splits into an interest component and a principal component. In the first month of a 20-year loan, ₹35,417 of your ₹43,391 EMI is interest and only ₹7,975 reduces the principal. By month 240 the split flips — almost the entire EMI is principal. This is why prepaying in the early years saves so much. How Much Salary You Need Banks typically apply a 50% FOIR (Fixed Obligation to Income Ratio) for home loans, which means your total EMIs (this loan plus any existing) cannot exceed half your gross monthly income. For a ₹43,391 EMI on a 20-year tenure, you need at least ₹86,782 monthly gross — roughly ₹10.4 lakh annual CTC. Some banks stretch FOIR to 65% for higher salaries. The Prepayment Math Suppose you prepay ₹2,00,000 once at the end of year 2 on a 20-year loan. The result: roughly ₹3,90,000 of interest saved over the remaining tenure, and the loan closes 11 months earlier. Prepayments early in the loan have outsized impact because they cut interest from the high-balance early years. The 80EEA / 24B Tax Angle Under the old tax regime, you can claim: - Section 24(b): Up to ₹2,00,000 per year on home loan interest (self-occupied property) - Section 80C: Up to ₹1,50,000 per year on principal repayment (within the overall ₹1.5L 80C limit) - Section 80EEA: Additional ₹1,50,000 on interest for first-time buyers (specific conditions on property value and loan sanction date) Under the new regime, none of these deductions apply — only standard deduction of ₹75,000 is available. For a salaried buyer, the old regime usually wins for the first 5-7 years of a home loan, then the math can flip as interest drops. Choosing the Right Tenure Run two scenarios on the EMI calculator: the longest tenure your bank offers (usually 30 years), and the shortest tenure your salary can comfortably support. Aim for the shortest you can afford, because each extra year of tenure adds disproportionate interest. A 15-year loan vs a 30-year loan on the same ₹50L principal saves you approximately ₹49 lakh in interest at the cost of ₹10,800 extra per month.
