How This Calculator Works
This calculator compares two scenarios over your chosen time period:
Buying Scenario
- Down payment + stamp duty/registration (~7%)
- Monthly EMI payments for the loan tenure
- Annual maintenance costs (~1% of property value)
- Property appreciation over the analysis period
Renting + Investing Scenario
- Invest the down payment + registration cost upfront
- Monthly savings (EMI + maintenance - rent) invested in mutual funds
- Rent increases annually at the specified rate
- All savings grow at the expected investment return rate
Key Formulas Used
EMI: P × r × (1+r)^n / ((1+r)^n - 1)
Property Value: Price × (1 + appreciation)^years
Investment Growth: Principal × (1 + return)^years
Net Buying Wealth: Property Value - Outstanding Loan
Net Renting Wealth: Total Investment Corpus
Frequently Asked Questions - Rent vs Buy
Is renting better than buying a house in India?
It depends on your city, property prices, rent levels, and investment discipline. In expensive metros like Mumbai and Bangalore where rent-to-price ratio is low (1.5-2.5%), renting + investing often wins. In tier-2 cities with higher rental yields (3-4%), buying may be better.
What factors should I consider before buying?
Compare: total EMI payments over loan tenure, down payment opportunity cost, stamp duty (5-7%), maintenance costs, property appreciation potential, tax benefits (Section 24/80C), and what your money could earn if invested in equity mutual funds instead.
Does buying a house always create wealth?
No. In many Indian cities, property prices have barely kept pace with inflation (4-6% CAGR) over the last decade. Meanwhile, equity mutual fund SIPs have delivered 12-15% CAGR. The interest paid on home loans (total 1.5-2x the property price) further reduces buying's financial advantage.
What is the 5% rule?
Multiply the property's value by 5% and divide by 12. If your monthly rent is less than this amount, renting is likely better financially. For a ₹1 Cr property: 5% = ₹5L/year = ₹41,667/month. If rent is ₹25,000, renting wins.
How does home loan interest affect the decision?
At 8.5% interest for 20 years, you pay about ₹2.07 for every ₹1 borrowed. A ₹50L loan costs ₹1.03 Cr in total payments. This massive interest cost is the biggest hidden expense of home ownership that makes renting + investing attractive.
Can investing while renting generate higher returns?
Yes, if you have the discipline. Investing the down payment and monthly EMI-rent difference in equity mutual funds (12-15% historical CAGR) often beats property appreciation (4-7% in most cities). The key requirement is investment discipline — the money saved must actually be invested, not spent.
Rent vs buy — a financial framework
Buying a home builds equity but ties up capital in down payment, EMIs, maintenance, property tax, and stamp duty (5–7% in many states). Renting keeps mobility and invests the down payment difference in equity mutual funds — historically 12%+ CAGR over 15+ years. The better choice depends on city, tenure of stay, rental yield, and loan rate.
Rule of thumb: if annual rent is less than 3% of property price (e.g., ₹30k/month on ₹1.2 Cr = 3%), renting may be financially optimal in expensive metros. In tier-2 cities with 4–5% rental yield, buying often wins if you plan to stay 7+ years.
Hidden costs of home ownership
Include registration, GST on under-construction, society maintenance, renovation every 10–15 years, and opportunity cost of down payment. A ₹30 lakh down payment at 12% CAGR for 20 years grows to ~₹2.9 crore — factor this into buy-side math.
When buying makes emotional sense
Stability, school proximity, and freedom to renovate are non-financial benefits. If rent-vs-buy math is close, personal preference matters. Use our EMI calculator for loan scenarios after running this comparison.
