How to Calculate Your Rent vs Buy Break-Even Year

Published 30 June 2026 · Investing

Priya in Bengaluru has been going back and forth on the rent vs buy decision for three years. Every time she comes close to deciding, someone tells her a different number. Her father says buy after 5 years. Her colleague says the break-even is 12 years. Her CA says it depends on too many assumptions. They are all technically correct — but Priya needs a method, not a conclusion. Here is the four-step calculation she can run with her own numbers.

Step 1: Calculate Annual Ownership Cost

Property price: ₹80L. Down payment: 20% = ₹16L. Home loan: ₹64L at 8.5% for 20 years. Monthly EMI: ₹55,816. Annual EMI outgo: ₹6.7L.

Add maintenance: ₹5,000/month = ₹60,000/year. Add property tax: ₹30,000/year. Subtract Section 24(b) tax saving (old regime at 30% bracket): approximately ₹50,000/year in the early years. Net annual ownership cost: ₹6.7L + ₹0.6L + ₹0.3L − ₹0.5L = ₹7.1L/year.

Step 2: Calculate Annual Renting Cost

Rent for a comparable flat in Bengaluru (Whitefield area): ₹28,000/month. Annual renting cost: ₹3.36L/year. This is the full cost — no hidden extras beyond the deposit (which earns interest).

Step 3: Invest the Difference

Annual cost difference: ₹7.1L − ₹3.36L = ₹3.74L/year (approximately ₹31,167/month) invested in equity SIP at 12% p.a. This is the renter's additional investment capacity. Plus: the ₹16L down payment not deployed in property, invested as lump sum at 12%.

Step 4: Track Owner Equity vs Renter Corpus by Year

At year 10, owner equity (₹77.4L) barely exceeds the renter's corpus (₹72.1L) — a thin buyer advantage. But by year 15, the renter's compounding has overtaken: ₹1.64 crore vs ₹1.24 crore owner equity. At year 20, the gap is ₹1.17 crore in the renter's favour. The break-even in this scenario is around year 11–12 — after which the renter's portfolio pulls ahead and accelerates. The buyer never catches up in this Bengaluru scenario with 5% appreciation.

How Changing One Assumption Shifts the Break-Even

The 5% property appreciation assumption is conservative for Bengaluru's tech corridor but realistic for outlying areas. At 7% appreciation: home value at year 20 is ₹3.1 crore. Owner equity: ₹3.1 crore. Renter corpus: ₹3.29 crore. Nearly identical — the buyer and renter end up at similar wealth levels, but the buyer owns a real asset while the renter has a liquid portfolio.

At 8% appreciation (Mumbai premium): home value at year 20 is ₹3.73 crore. Owner equity: ₹3.73 crore. Renter corpus: ₹3.29 crore. Buyer wins by ₹44L — the high-appreciation scenario tips the scales back to buying. This is why the appreciation assumption is the most sensitive variable in the entire model.

What Most People Get Wrong

They assume buying eventually "wins" — that the break-even comes, buying pulls ahead, and it stays ahead forever. In high price-to-rent cities like Mumbai and Delhi, this is often false. The renter's compounding advantage can outpace property appreciation indefinitely if the investment difference is large enough and consistently deployed. The only scenarios where buying definitively wins over a 20-year horizon are: high property appreciation (7%+ p.a.), low investment return differential (the renter earns only 8–9%), or the renter fails to invest the difference consistently. That last point is real — many renters do not actually invest the difference. But that is a behavioural failure, not a financial argument for buying.

Frequently Asked Questions

How do I calculate the rent vs buy break-even year?

Step 1: Calculate total annual cost of owning (EMI + maintenance + property tax − tax savings). Step 2: Calculate total annual cost of renting (rent). Step 3: Invest the annual cost difference in equity at 12%. Step 4: Track when cumulative owner equity (home value − outstanding loan) exceeds cumulative renter wealth (investment corpus − zero debt). That year is the break-even.

How many years does it typically take to break even renting vs buying in India?

In cities with price-to-rent ratios below 20 (e.g., Hyderabad, Pune outskirts): 8–12 years. In cities with ratios of 25–30 (Bengaluru, Chennai): 12–18 years. In cities with ratios above 30 (Mumbai, Delhi premium areas): 20+ years, often never within a 20-year horizon.

What assumptions affect the rent vs buy break-even calculation?

Key assumptions: (1) property appreciation rate (4% vs 8% dramatically changes the answer), (2) investment return on the difference (10% vs 12%), (3) rent escalation rate (typically 5–8% per year in Indian cities), (4) loan interest rate, (5) holding period.

What happens if I sell the property before the break-even year?

Selling before break-even means buying was more expensive than renting for that period. Additionally, selling costs (stamp duty, registration, brokerage) are typically 6–10% of the sale value — these must be accounted for in the break-even calculation.

Does rent escalation affect the break-even year?

Yes — rent escalation makes buying look better over time. If rent increases 7% per year while your EMI stays fixed, the "rent" side costs more each year while ownership costs are stable. This pulls the break-even earlier for buyers.

Have you run a year-by-year comparison of owner equity vs renter corpus for your specific city — or assumed that buying always wins in the long run?
