What is the buy-vs-rent decision?
The home loan vs rent decision is one of the biggest financial choices most people make. It involves weighing the total cost of buying (EMI × tenure + down payment + maintenance + property tax + opportunity cost of money locked) against the total cost of renting (rent × tenure + rent escalation + investment return on saved-down-payment).
There's no universal answer. For some life situations and cities, buying wins. For others, renting + investing the difference wins comfortably. This calculator runs the math both ways with your specific numbers.
How is the comparison calculated?
CalcMaster computes two parallel financial streams over your time horizon:
Buying stream:
Buying cost = Down payment + (EMI × months)
House value at end = Purchase price × (1 + appreciation %)^years
Net buyer cost = Buying cost − House value at end
Renting stream:
Renting cost = Sum of monthly rent (with annual escalation)
Renter corpus = Down payment + (EMI − rent each month) invested at return %
Net renter cost = Renting cost − Renter corpus at end
The lower net cost wins.
Worked example
Mumbai 2-BHK: ₹1.2 cr purchase price (or ₹40,000/month rent). 20% down, 8.5% loan rate, 20-year tenure. Rent grows 7%/year. Equity SIP returns 12%. Property appreciates 5%/year.
| Metric | Buying | Renting |
|---|---|---|
| Down payment | ₹24 L | ₹0 |
| Monthly EMI / rent | ₹83,310 | ₹40,000 (year 1) |
| 20-year outflow | ₹24 L + ₹2.0 cr = ₹2.24 cr | ₹1.65 cr (compounding rent) |
| House value at year 20 | ₹3.18 cr | — |
| Renter corpus (SIP of EMI minus rent) | — | ₹3.5 cr |
| Net cost | −₹94 L (gained equity) | −₹1.85 cr (gained equity) |
In this scenario, renting + investing wins by ~₹91 L over 20 years.
But the answer flips dramatically if:
- You stay 25+ years (buying advantage compounds)
- Rent escalates faster than 7%
- Property appreciation > 6%
- Equity returns are lower than 12%
When buying wins
| Condition | Why |
|---|---|
| Time horizon ≥ 8 years | Stamp duty + registration costs (4-8% of price) amortize over time |
| You'll likely stay there | Selling within 5 years gives up tax-LTCG benefits and incurs broker fees |
| Rental yield > 3.5% of property value | Rent is high relative to property; buying makes sense |
| You value emotional ownership | "My home" has real psychological value not captured by math |
| Stable income that can absorb EMI | EMI is a 20-year commitment; income volatility is a problem |
| Tax bracket 30% | Section 24(b) ₹2 L interest deduction matters |
When renting wins
| Condition | Why |
|---|---|
| Time horizon < 5 years | Transaction costs (stamp + registration + broker) dominate |
| Career flexibility important | Easier to move for jobs |
| Rental yield < 2.5% | Rent is low relative to property; renting + investing is mathematically better |
| Property prices stagnant | If appreciation is < 5%, buyer's equity build-up is slow |
| Equity return expectations > 12% | Renter's invested-savings compound aggressively |
| You're investing the difference religiously | The math works only if EMI-rent gap actually goes into equity |
Components and inputs explained
House price
Total acquisition cost — including stamp duty + registration (4-8%) + brokerage (1-2%). Don't use just the sale price.
Down payment %
What you pay upfront. Standard 20% gives best loan rates.
Loan rate
Bank-quoted home loan rate (current 8.4-9.5% in India for prime borrowers).
Tenure
Loan tenure in years (typical 15-25).
Monthly rent (equivalent)
Current monthly rent for a comparable property in the same area.
Rent growth
Annual rent escalation. Typical 5-8% in major Indian cities; can spike during demand surges.
Investment return
Expected return on the renter's "saved" money (the down payment + the difference between EMI and rent). Use 10-12% for equity-heavy SIPs.
Property appreciation
Annual real-estate appreciation. India urban: 4-7% historical; can be -2% to +15% in specific cycles.
The Indian context
Several India-specific factors tilt the math:
- Tax-free LTCG on residential property after 2 yrs hold (vs equity LTCG at 12.5%)
- Section 24(b) home-loan-interest deduction (₹2 L/year, old regime only)
- Section 80C principal repayment deduction (₹1.5 L/year)
- Capital gains exemption under Section 54 for upgrading to a bigger home
- Rental yields are low (2-3% in metros) — math favors renting + investing in equity
- Property is illiquid — selling in 3-6 months is realistic, not 30 days
These tend to favor buying for long-term residence, renting + equity for short-term or career-mobile situations.
Considerations
- Don't include the house in "net worth" for retirement planning. Your primary residence isn't accessible cash.
- Maintenance is real. Society dues + property tax + repairs add 1-2% of property value/year. Renters skip this.
- The "buyer wins because rent is wasted" argument is misleading. Interest on home loan is also "wasted" — both rent and loan interest disappear.
- Geographic arbitrage: in some Indian cities (Mumbai, Bangalore, Pune), renting and investing the difference beats buying for ~all time horizons. In Tier-2 cities with lower property prices, buying wins faster.
Limitations
- The calculator assumes constant rates and growth. Real rates fluctuate.
- Doesn't model property maintenance, society fees, property tax, insurance.
- Doesn't account for emotional / lifestyle value of ownership.
- Doesn't model job relocation scenarios.
- Doesn't include capital gains tax on property sale (LTCG 20% with indexation, exempt under specific sections).

Final note. The buy-vs-rent decision isn't only financial. Stability, family, schools, emotional ownership all matter — and the math is only one input. Run the math with your specific numbers (price, rent, rate, time horizon), then weigh it against the non-financial factors. This calculator gives you the cold numbers; you decide what to do with them.
