You are wasting ₹22,000 every month on rent. That money just disappears.
Vikram's colleague bought a flat for ₹70 lakh with a ₹56 lakh home loan at 8.5% for 20 years. EMI: ₹48,700. 'You're throwing money away on rent,' he tells Vikram. Vikram wants to know if that's actually true.
📌
The real cost of that ₹70 lakh flat
Purchase price: ₹70 lakh
Stamp duty + registration (6%): ₹4.2 lakh
Home loan: ₹56 lakh at 8.5% for 20 years
EMI: ₹48,700/month
Total interest over 20 years: ₹61 lakh
Total cost of the flat:
₹70L (price) + ₹4.2L (taxes) + ₹61L (interest) = ₹1,35,20,000
The ₹70 lakh flat actually costs ₹1.35 crore.
20 years later — buy vs rent-and-invest
₹224L
Buy: flat worth ₹2.24 crore (6% appreciation)
₹265L
Rent + invest difference: ₹2.65 crore corpus
₹ in lakhs. Rent ₹22,000/month. EMI ₹48,700. Investing ₹26,700/month gap at 12% CAGR.
⚠️
The calculation that shows renting often wins financially
Vikram rents at ₹22,000/month. His colleague's EMI is ₹48,700.
Difference: ₹26,700/month.
If Vikram invests ₹26,700/month at 12% CAGR for 20 years:
Corpus = ₹2.65 crore
His colleague's flat at 6% annual appreciation:
Flat worth in 20 years = ₹2.24 crore
Minus ₹61 lakh interest paid = effective net: ~₹1.63 crore equivalent
Purely financially: Vikram wins by a meaningful margin. In high price-to-rent cities (Mumbai, Delhi, Bengaluru), renting and investing the difference frequently outperforms buying.

The price-to-rent ratio — a quick city check
Price-to-rent ratio = property price ÷ annual rent.
If a flat costs ₹80 lakh and rents for ₹25,000/month (₹3 lakh/year):
Ratio = ₹80L ÷ ₹3L = 26.7
Below 15: buying is likely better financially.
15–20: borderline — personal factors decide.
Above 20: renting is likely better financially.
Mumbai: ratios of 30–50 are common.
Pune/Hyderabad: 18–25 in most areas.
Tier 2 cities: 12–18 in many areas.
