Reviewed July 2026Rent versus buy is the largest financial decision most households face, and both camps argue it badly. "Rent is money down the drain" ignores that loan interest, property taxes and maintenance are equally unrecoverable. "Renting and investing the difference always wins" assumes a discipline most people don't have.
The honest comparison sets total unrecoverable costs of owning (interest, taxes, maintenance, transaction costs, opportunity cost of the down payment) against rent, and then adds what each path builds: home equity and appreciation on one side, an invested portfolio on the other.
This calculator runs that comparison for your actual numbers. Below: the framework, the price-to-rent shortcut, worked examples and the non-financial factors that legitimately override the spreadsheet.
The framework: unrecoverable costs on both sides
Cost of renting = annual rent (grows ~5–8%/yr in India) Cost of owning = loan interest + property tax + maintenance & society charges (~1–2% of value/yr) + transaction costs amortized (stamp duty ~5–8%, brokerage, registration) + opportunity cost: down payment × (investment return − appreciation) − principal repaid (that part builds equity, not cost)
Owning wins when appreciation plus the rent you avoid outrun interest, taxes, maintenance and the returns your down payment could have earned elsewhere. Renting wins when the price-to-rent ratio is high and disciplined investing captures the difference. Neither wins universally — inputs decide.
The price-to-rent shortcut
A ₹1.2 crore flat renting at ₹30,000/month has a ratio of 33 (1.2 cr ÷ 3.6 lakh) — the rent is only 3% of price annually while a loan costs ~8.75%. High Indian metro ratios are why renting the same flat you'd buy is often financially efficient there, and why the calculus flips in smaller cities.
| Ratio | Reading | Typical of |
|---|---|---|
| Under 20 | Buying strongly favoured | Many US suburbs, Tier-2/3 India outskirts |
| 20–30 | Genuinely close — run full math | Most Indian metros' mid segments |
| 30–40 | Renting usually cheaper | Prime Mumbai/Delhi/Bengaluru localities |
| Above 40 | Renting decisively cheaper | Luxury segments in Indian metros |
Worked example: ₹1 crore flat vs ₹28,000 rent
- Buy: ₹20 lakh down + ₹6 lakh stamp/registration; ₹80 lakh loan at 8.75%/20 yr = ₹70,697 EMI.
- Year-1 owning costs: interest ~₹6.9 lakh + tax/maintenance ~₹1.5 lakh = ₹8.4 lakh unrecoverable; principal repaid ₹1.6 lakh builds equity.
- Rent path: ₹3.36 lakh rent; the ₹26 lakh upfront money invested at 11% earns ~₹2.9 lakh; plus the monthly gap (EMI+costs − rent ≈ ₹47,000) invested as SIP.
- Break-even driver: if the flat appreciates ≥ ~7%/yr, buying pulls ahead within 8–10 years; at 4–5% appreciation, the renter-investor stays ahead for decades.
- Sensitivity: the result flips on three inputs — appreciation rate, investment return and how long you stay. Run your honest numbers, not hopeful ones.
What the spreadsheet can't price
- For buying: stability (no landlord risk, no forced moves), freedom to modify, schooling continuity, forced saving via EMI — the discipline value is real for most households.
- For renting: mobility for career moves, flexibility to upgrade/downsize, no concentration of net worth in one illiquid asset, no repair surprises.
- The forced-saving point deserves respect: 'rent and invest the difference' only works if the difference is actually invested, automatically, every month.
How to use this calculator well
- Enter the property price and the realistic monthly rent for the same home (not a cheaper one — compare like for like).
- Set loan terms, expected property appreciation (India long-run: ~5–8% residential, city-dependent), rent inflation (~5–8%) and the return you'd earn on invested savings (10–12% equity assumption).
- Set your honest time horizon — how long you'll actually keep this home.
- Compare the two net-worth paths at your horizon; then stress-test appreciation ±2% before deciding.
Common mistakes
- Comparing EMI to rent directly — the EMI's principal component is saving, not cost; and owning adds taxes and maintenance rent doesn't.
- Ignoring the down payment's opportunity cost — ₹26 lakh at 11% is ₹2.9 lakh/year of invisible cost.
- Assuming double-digit property appreciation because a neighbour's flat did that in 2003–2008.
- Buying with less than a 5–7 year horizon and eating the full transaction costs.
- Letting the binary framing hide the third option: renting where you work, buying an investment property where yields are better.
Frequently asked questions
Glossary
- Price-to-rent ratio
- Property price ÷ annual rent — the quick screen for rent-vs-buy economics.
- Unrecoverable cost
- Money spent on housing that builds no asset: rent, interest, taxes, maintenance.
- Opportunity cost
- Returns the down payment would have earned if invested instead of locked in the property.
- Transaction costs
- Stamp duty, registration and brokerage — the 7–9% round-trip toll on buying and selling.
- Appreciation
- Annual growth in property value; the buyer's main wealth engine.
- HRA exemption
- The Indian salary tax exemption renters can claim against rent paid (old regime).
- Forced saving
- The EMI's principal component — automatic equity building that requires no discipline.
- Rental yield
- Annual rent ÷ property price — the inverse of price-to-rent; 2.5–3.5% is typical in Indian metros.
Key takeaways
Rent vs buy is a comparison of unrecoverable costs plus what each path builds. Buying needs time (5–7+ years), a sane price-to-rent ratio and honest appreciation assumptions; renting needs the discipline to actually invest the difference. Check the price-to-rent ratio first, run the full calculation with conservative inputs, then let the non-financial factors — stability versus mobility — break the tie the spreadsheet leaves.
Enter your city's real price and rent numbers above — then stress-test appreciation at ±2% and see which side needs heroic assumptions to win.
