What is the Rent vs Buy Calculator?
The Rent vs Buy Calculator helps you answer one of the most consequential financial questions in India today: is it smarter to purchase a home or continue renting and invest the difference? With residential property prices in Tier-1 cities like Mumbai, Bengaluru, and Delhi-NCR ranging from ₹60 lakh to several crores, and with home loan interest rates fluctuating between 8.5% and 9.5% (as of mid-2026), this decision can shape your wealth trajectory for decades.
India's real estate market has unique characteristics that make a generic global calculator insufficient. Property registration charges (typically 5-7% of the circle rate), stamp duty varying by state, GST on under-construction properties at 5% (without input tax credit), and the Section 80C deduction of up to ₹1.5 lakh on principal repayment under the Income Tax Act — all of these factors materially alter the true cost of ownership. On the rental side, House Rent Allowance (HRA) exemptions under Section 10(13A) can significantly reduce taxable income for salaried employees, making renting more tax-efficient than many assume.
This calculator computes the total financial cost of buying versus renting over your chosen time horizon, factoring in opportunity cost — what your down payment could earn if invested in equity mutual funds or index funds instead. It gives you a clear, India-specific breakeven point so you can make a data-driven decision rather than an emotional one.
How does it work?
The calculator compares two financial paths over a user-defined period (typically 10-20 years). For the **Buy path**, it computes: Total Cost of Buying = Down Payment + (EMI × Loan Tenure in months) + Registration & Stamp Duty + Maintenance Costs + Property Tax − Estimated Property Appreciation − Tax Savings on Home Loan (Section 24(b) allows up to ₹2 lakh deduction on interest per year for self-occupied property, and Section 80C allows ₹1.5 lakh on principal). EMI is calculated using the standard formula: EMI = P × r × (1+r)^n / [(1+r)^n − 1], where P is the loan principal, r is the monthly interest rate, and n is the tenure in months.
For the **Rent path**, it computes: Total Cost of Renting = Cumulative Rent Paid (with annual escalation, typically 5-8% in Indian cities) − HRA Tax Savings + Opportunity Cost of Down Payment invested in market instruments. The opportunity cost uses the compound growth formula: FV = PV × (1 + r)^n, where PV is your down payment amount, r is the assumed annual return (e.g., 12% for equity mutual funds based on long-term Nifty 50 CAGR), and n is the number of years. Similarly, the monthly EMI-versus-rent differential, if invested via SIP, grows as: M = P × [(1+r)^n − 1] / r × (1+r), where P is the monthly surplus and r is the monthly return rate.
The net result tells you which path leaves you wealthier at the end of your chosen horizon, and at what year the crossover (breakeven) occurs — after which buying becomes more advantageous as the property appreciates and the loan gets repaid.
Worked example
Consider Priya, 31, a software engineer in Bengaluru earning ₹18 LPA. She is evaluating a 2BHK apartment in Whitefield priced at ₹85 lakh. With a 20% down payment of ₹17 lakh and a home loan of ₹68 lakh at 9% for 20 years, her EMI works out to approximately ₹61,200 per month. Add stamp duty and registration of roughly ₹5.1 lakh (6% in Karnataka) and annual maintenance of ₹30,000, and her total outflow in Year 1 is around ₹8.9 lakh. She currently rents a similar flat for ₹28,000 per month, saving ₹33,200 monthly compared to the EMI.
If Priya instead invests her ₹17 lakh down payment in an equity index fund earning 12% CAGR, it grows to approximately ₹93 lakh in 15 years. Her monthly SIP of ₹33,200 (the EMI-rent gap) at 12% CAGR accumulates to roughly ₹1.63 crore over 15 years. Meanwhile, the property appreciating at 6% CAGR would be worth about ₹2.04 crore in 15 years, against an outstanding loan of near zero by then. The calculator shows that in Priya's case, buying crosses the financial breakeven at around Year 13 — meaning renting and investing is better for the first 12 years, but buying wins over a 15+ year horizon. Her HRA exemption of roughly ₹1.68 lakh annually also reduces her tax liability while renting, further shifting the early-year advantage toward renting.
When to use this calculator
- 1You are planning to stay in the same city for at least 7-10 years and want to know if buying now makes financial sense versus continuing to rent.
- 2You have received a job offer in a new city and need to decide quickly whether to buy or rent in the new location before relocating.
- 3You are nearing retirement and evaluating whether to use your corpus to purchase a home outright or invest it and use returns to pay rent.
- 4You are a first-time homebuyer comparing PMAY-eligible affordable housing with interest subsidy under CLSS against continuing to rent in the same locality.
- 5Your employer offers a large HRA component and you want to quantify the tax benefit of renting before committing to a purchase that eliminates this exemption.
Common mistakes to avoid
- ✕Ignoring the full cost of ownership: Most buyers count only the EMI but overlook stamp duty (4-8% depending on state), registration fees, GST on under-construction flats (5%), society maintenance (₹3-8 per sq ft monthly), property tax, and home insurance — which can add 15-20% to the effective purchase cost.
- ✕Overestimating property appreciation: Many Indians assume 10-12% annual property price growth based on anecdotal peaks, but RBI's House Price Index data shows average real (inflation-adjusted) residential property appreciation has been 2-4% CAGR in most cities over the last decade, significantly weakening the buying case.
- ✕Undervaluing the HRA tax benefit while renting: Salaried employees in the 30% tax bracket living in metros can exempt a significant portion of HRA — up to the minimum of: actual HRA received, 50% of basic salary (metro), or rent paid minus 10% of basic. This can amount to ₹1-3 lakh in annual tax savings, which buyers permanently forgo.
- ✕Treating home loan prepayment as an investment: Many families divert all surplus income toward loan prepayment to save interest, without realising that at a 9% home loan rate (with a 30% tax deduction on interest, effective rate ~6.3%), equity mutual funds historically outperform this 'guaranteed return' significantly over a 10+ year horizon.
- ✕Not accounting for rent escalation correctly: Buyers often compare today's EMI against today's rent and conclude buying is better, ignoring that rents in Indian metros typically escalate 5-10% annually, which means the rent-vs-EMI gap narrows significantly over time and should be modeled dynamically rather than held constant.
Frequently asked questions
- Is it better to buy or rent a house in India in 2026?
- There is no universal answer — it depends on your city, income, time horizon, and risk appetite. In high-cost cities like Mumbai and Bengaluru where price-to-rent ratios exceed 40x (meaning annual rent is less than 2.5% of property value), renting and investing the difference often builds more wealth over 10-12 years. In Tier-2 cities like Jaipur or Nagpur with price-to-rent ratios of 15-20x, buying tends to be financially superior sooner. Use the calculator with your specific numbers rather than following a general rule.
- How does the HRA exemption affect the rent vs buy decision?
- HRA exemption under Section 10(13A) can be a powerful reason to continue renting if you are salaried. The exemption is the minimum of: actual HRA received, 50% of basic salary (40% for non-metros), or rent paid minus 10% of basic. For example, if your basic is ₹8 lakh and you pay ₹30,000/month rent in Bengaluru, your annual HRA exemption can be up to ₹3.6 lakh, saving ₹1.08 lakh in tax at 30% bracket. This benefit disappears when you buy. However, if you take a home loan, you get Section 24(b) interest deduction (up to ₹2 lakh for self-occupied) and Section 80C principal deduction (up to ₹1.5 lakh), which partially compensate.
- What is a good price-to-rent ratio to decide when buying makes sense?
- The price-to-rent ratio (property price divided by annual rent for a comparable unit) is a quick benchmark. A ratio below 15 generally favours buying; between 15-20 is borderline; above 20 favours renting and investing. In India, most Tier-1 city markets have ratios of 25-45x, making renting mathematically superior for shorter holding periods. For instance, a flat priced at ₹1 crore renting for ₹20,000/month has a ratio of 41.7x, suggesting you would need to hold for 15+ years with above-average appreciation for buying to win financially.
- Can I claim both HRA and home loan deductions simultaneously?
- Yes, in certain situations. If your purchased property is in a different city from where you work and live on rent, you can claim both HRA exemption on the rent you pay AND the home loan deductions (Section 24(b) for interest and Section 80C for principal) on the EMI for the other property. However, if you own and live in the property yourself, you cannot claim HRA. This dual-benefit situation is common for people who buy a flat in their home city (e.g., Lucknow) while working and renting in another city (e.g., Gurugram).
- How much down payment should I keep ready before buying a house in India?
- RBI mandates that banks can finance a maximum of 75-90% of the property value (LTV ratio depends on loan amount: 90% LTV for loans up to ₹30 lakh, 80% for ₹30-75 lakh, and 75% for loans above ₹75 lakh). So minimum down payment is 10-25% of property value. However, financial planners recommend keeping total debt below 40% of monthly take-home pay (EMI-to-income ratio) and retaining 6 months of expenses as an emergency fund after the down payment. For a ₹80 lakh flat, you should ideally have ₹16-20 lakh as down payment plus ₹5-6 lakh for stamp duty, registration, and moving costs — totalling ₹21-26 lakh liquid savings before buying.
