The 20-year comparison

The buyer pays the down payment and stamp duty on day 1, then the EMI and maintenance each month. The renter puts the same day-1 money into a Nifty 50 index fund, pays rent, and each month invests whatever the buyer spends over rent. Whoever spends less in a month invests the difference, so both start and continue with the same money.

Rent avoided is the buyer’s return on the flat, on top of price growth. Here that is a 3.2% yield, against a 8.5% loan rate, which is why price growth has to do most of the work for buying to win.

How we worked this out. Typical 2BHK prices and rents are our estimates for 2026, not listings. Loan at 8.5% for 20 years with 20% down; 7% stamp duty + registration (actual rates vary by state); maintenance 0.5% of the home value a year; the renter invests in a Nifty 50 index fund at 12% a year. Price and rent growth follow each locality’s 2014–2024 trend, which may not continue. Figures are before tax and not adjusted for inflation. How the calculator works.
