Introducing the Rent vs Buy Calculator — Find Your Break-Even Year

Buying a home is the largest financial decision most people make. Yet most rent-vs-buy tools reduce the comparison to a single number — monthly EMI vs current rent — and leave out the factors that actually matter: home appreciation, annual maintenance, property tax, the opportunity cost of the down payment, and rising rent.

Today we are launching the Rent vs Buy Calculator — a full financial model that compares both paths over any horizon you choose.

What it calculates

Enter your home price, down payment percentage, mortgage rate, and loan tenure. Add maintenance and property tax rates, and the registration / closing cost percentage. On the rent side, enter your current monthly rent, expected annual rent increase, and the return rate you would earn by investing the down payment instead of using it to buy.

Click Compare, and you get:

• Monthly EMI for the buy scenario vs your current rent
• Break-even year — the exact year when cumulative buying costs (net of equity built) fall below cumulative renting costs (net of the invested down payment’s growth)
• Net advantage — how much better one path is over the other in rupees
• End-of-horizon comparison — home value, equity built, and the renter’s investment portfolio value after your chosen number of years
• Year-by-year table — cumulative buy cost, cumulative rent cost, and the buy-vs-rent advantage for each year

The detail most tools skip

The single most important factor that standard rent-vs-buy tools miss is the opportunity cost of the down payment.

When you buy a home, the down payment is locked in property. If you rent instead and invest that same amount at a reasonable equity market return (say 10% per year), the renter builds a portfolio that compounds over time. Our calculator models both paths: the buyer accumulates equity as the home appreciates and the loan is paid down; the renter’s invested down payment grows in the market. The fair comparison is between these two outcomes — not just EMI vs rent.

This is why the calculator asks for an investment return rate. Set it to what you would realistically earn on a diversified equity portfolio. 10–12% per annum is a reasonable long-run assumption for Indian equity markets, though past returns do not guarantee future results.

100% in-browser, no data sent anywhere

Every calculation runs locally in your browser using the inputs you provide. Nothing is stored, logged, or sent to any server. Close the tab and the numbers are gone.

Where to start

Open the Rent vs Buy Calculator and run your base case with the actual numbers for a home you are considering. Then try pushing appreciation to 8% (optimistic) and down to 4% (conservative) to see how sensitive the result is. Look at the break-even year — if it is beyond your likely holding period, renting and investing is probably the smarter financial choice for now.
