Rent vs Buy Calculator
Compare renting vs buying a house.
Property & Rent Parameters
Deciding whether to buy a home or continue renting is one of the biggest financial and emotional milestones in adult life. The Finzorio Rent vs Buy Calculator compares the total long-term financial outcome of purchasing a property with a mortgage against renting and investing the down payment and monthly cash flow differential in wealth-generating assets.
The True Financial Trade-Off: Renting vs Buying a Home
The debate between renting and buying is often oversimplified as "paying rent is throwing money away." In reality, homeownership incurs heavy unrecoverable costs of its own — including mortgage interest payments, property registration & stamp duty, society maintenance, property taxes, home insurance, and opportunity cost on the down payment.
When residential rental yields in major metro cities hover around 2.5%–3.5% while home loan interest rates are 8.5%–9.0%, renting and investing the financial difference in diversified equity SIPs (yielding 12%+) often builds substantial net worth over a 10-to-15-year horizon.
Unrecoverable Costs Comparison: Buying vs Renting
Compare the recurring and upfront sunk costs on both sides of the decision:
| Cost Category | Buying a Home | Renting a Home |
|---|---|---|
| Upfront Cash Required | 20% Down Payment + 6–8% Stamp Duty & Registration | 1–6 Months Refundable Security Deposit |
| Monthly Debt / Outflow | Fixed Loan EMI (Principal + Interest components) | Monthly Rent (Increases 5–8% annually) |
| Maintenance & Repairs | Owner pays 100% of major structural & society maintenance | Landlord covers major structural maintenance |
| Property Tax & Insurance | Annual Municipal Property Tax + Building Insurance | Zero property tax liability for tenant |
| Capital Opportunity Cost | Down payment is locked in physical illiquid brick-and-mortar | Down payment is invested in liquid compound assets (Equity SIPs/FDs) |
| Flexibility & Relocation | High exit friction (Brokerage, capital gains tax, time to sell) | Full career and geographical mobility on lease expiry |
Worked Example: ₹1 Crore Home Purchase vs ₹30,000/mo Rent (10-Year Horizon)
Scenario: A family in an Indian metro city compares buying a ₹1,00,00,000 (₹1 Crore) home versus renting a similar 2BHK flat at ₹30,000/month with 5% annual rent escalation.
Inputs
- Property Price: ₹1,00,00,000 | Down Payment (20%): ₹20,00,000 | Stamp Duty (6%): ₹6,00,000
- Home Loan Amount: ₹80,00,000 at 8.5% for 20 Years | Monthly EMI: ₹69,426
- Expected Property Appreciation: 5.5% CAGR
- Monthly Rent: ₹30,00,000 (5% annual increase) | Alternative SIP Return: 12.0% CAGR
Calculation
- Buying Scenario (10 Years): Total EMI paid = ₹83.3 Lakh (Interest = ₹54.4L, Principal = ₹28.9L). Maintenance & Duty = ₹12L. Total cash outgo = ₹1.15 Crore. Property value at 5.5% CAGR = ₹1.71 Crore. Remaining loan balance = ₹51.1 Lakh. Net Homeowner Equity = ₹1.20 Crore.
- Renting Scenario (10 Years): Total Rent Paid = ₹45.3 Lakh. The ₹26 Lakh upfront savings (Down payment + Stamp duty) invested at 12% grows to ₹80.7 Lakh. The monthly cash difference between EMI (₹69,426) and rent invested in a 12% SIP grows to ₹62.5 Lakh. Total Net Renting Wealth = ₹1.43 Crore.
Result: In this scenario, renting and investing the cash difference builds ~₹23 Lakh higher liquid net worth after 10 years, while buying provides physical security and an owned asset.
When Does Buying Make More Financial Sense?
- Long Holding Horizon (15+ Years): Over longer periods, mortgage EMIs remain fixed while market rents continue to compound higher.
- Emotional & Family Stability: Having complete autonomy over renovations, schooling stability for children, and freedom from sudden landlord lease terminations.
- High Rental Yield Markets (4%+): In tier-2 cities or suburban growth corridors where rental yields are higher relative to property acquisition costs.
- Retirement Security: Owning a debt-free residential property by retirement eliminates housing expense risks in old age.
