Rent vs Buy Calculator: Should You Rent or Buy a Home in India?
The 20× Annual Rent Rule
A property is financially worth buying when its price is less than 20 times the annual rent for a similar property. If a flat rents for ₹30,000/month (₹3.6L/year) and costs ₹80L to buy, the price-to-rent ratio is 80/3.6 = 22.2×. That’s above 20×, suggesting renting may be more cost-effective. In most Indian metros, this ratio has climbed to 25–40×, tilting the math toward renting for pure financial returns.
The Full Cost of Buying
People compare EMI to rent, but EMI is only part of the buying cost:
| Cost Component | Approximate Amount (₹80L Property) |
|---|---|
| Down payment (20%) | ₹16,00,000 |
| Registration + Stamp duty (8%) | ₹6,40,000 |
| Brokerage (1%) | ₹80,000 |
| Interior / renovation | ₹5,00,000–10,00,000 |
| Loan interest (8.5%, 20 years on ₹64L) | ₹69,30,000 |
| Maintenance (20 years @ ₹5K/month) | ₹12,00,000 |
| Property tax (20 years) | ₹2,40,000–60,000 |
| Total cost of ownership | ₹1.7–1.8 crore |
The Opportunity Cost of Down Payment
The ₹16–25L tied up in down payment + registration could be invested instead:
- ₹20L invested in equity mutual funds at 12% CAGR for 20 years = ₹1.93 crore
- The same ₹20L as down payment on a property that appreciates at 6%: property value = ₹2.57 crore, but the equity portion is only ₹80L initially + appreciation
This is the hidden cost of buying — you lose the compounding potential of your down payment. Use the SIP calculator to model what your down payment could grow to if invested instead.
When Buying Makes Sense
- You plan to live in the same city for 7+ years — the breakeven on buying vs renting typically takes 7–10 years in India
- Emotional security: Peace of mind, ability to customise, no landlord issues. This has real value that math can’t capture.
- Price-to-rent ratio is below 15–20 in your market
- Rental yields are low and property appreciation is high in the area
- You’re getting significant tax benefits (Section 24 interest deduction + 80C principal) under the old regime
When Renting Makes More Sense
- You’re early career and may relocate in 2–5 years
- Rent is significantly cheaper than EMI for similar properties (invest the difference)
- Local property market is overheated (price-to-rent > 25×)
- You can earn higher returns investing the down payment + monthly savings
