Rent vs Buy India, Rebuilt: A New Calculator, a Smarter Comparison Period, and More Accurate Numbers
We have spent the past few weeks rebuilding Rent vs Buy India from the ground up. The site is faster, easier to read on a phone, and, more importantly, more accurate. Here is what has changed: one new calculator, a set of upgrades to the tools you already use, and a handful of corrections to the numbers themselves.
A new calculator: buy to rent out, or invest instead?
Our newest tool, the Property Investment Calculator, answers a question the main calculator does not. If you have the money for a property, are you better off buying one to rent out, or investing that same money elsewhere?
It compares the two paths side by side, the landlord and the investor, and ends with a clear wealth verdict alongside your gross and net rental yield. The rental side is modelled honestly: vacancy, repainting, and brokerage are tied to how often tenants actually move, rather than assumed away with a flat annual figure. What you put into one path, you put into the other, so the comparison stays fair. For how that method differs from the other tools available in India, see our comparison of the main rent vs buy calculators.

Rent vs Buy: compare over any period you like
On the main Rent vs Buy calculator you can now set a comparison period separately from your loan tenure, anywhere from five to fifty years. Your decision horizon is not always the length of your loan. You might plan to reassess in ten years even on a twenty-year loan, and now you can model exactly that.
We have also added a toggle for what happens once the loan is paid off: do you keep investing the freed-up EMI each month, or stop? Both are reasonable choices, so we let you decide rather than quietly assuming one for you. (This toggle was rebuilt on 30 July 2026, and it no longer decides which path wins. See the update below.)
The Excel calculator, rethought
The downloadable Excel model got the most fundamental change of all. The old sheet quietly compared unequal budgets. Once the home loan was paid off, it credited the buyer the full EMI as fresh monthly investment, but charged the renter only their rent. The two sides were never spending the same amount, which tilted the comparison towards buying.
The rebuilt sheet puts both paths on an equal monthly budget, with a single Yes or No toggle: keep investing the freed-up EMI after the loan ends, or do not. We also fixed the very first month, where the renter's opening surplus was being dropped instead of invested, so it now compounds from month one. The Excel model now follows the same method as the calculator on the site.
We also corrected some numbers
While rebuilding, we audited every calculator against its own logic and fixed three things that were quietly off:
- The True Rental Expense calculator now counts your first move-in costs, the brokerage, moving, and furnishing you pay when you first rent a home. The old version skipped them, which understated the real cost of renting.
- It also reports the rent you actually paid in the final year, rather than an inflated figure for a year you never reach.
- The Affordability calculator now sizes your loan correctly when your down payment is larger than the 20% minimum, so the extra cash reduces your loan instead of being ignored.
If you have used these tools before, your results may shift a little. That is the corrections at work, and the new figures are the more accurate ones.
Update, 30 July 2026: the owner invests too
The freed-up EMI toggle described above has been rebuilt, because the calculator on this site was not doing what its own label promised, nor what the Excel model does.
Until now only the renter held investments. The owner's wealth was home equity and nothing else. That is fine while the loan runs, but not after it. Once the EMI stops, the owner is spending far less each month than the renter, and the calculator had nowhere to put that difference except the renter's portfolio, which it drained instead. Over a long horizon the figure stopped meaning anything: a ten-year loan measured over forty years had the renter holding minus ₹12.95 crore.
Both paths now draw on a single housing budget, which is what the owner spends while the loan runs: the EMI plus maintenance, property tax, and insurance. Each path pays for its own housing out of that budget and invests whatever is left. While the loan runs the owner spends the lot and the renter banks the gap, exactly as before. Once the loan is repaid the owner invests the EMI it no longer pays, so the buying side is now a home and a portfolio rather than a home alone. This is the method the Excel model has used since the rebuild. The site calculator now matches it, which is what we said in July and is true from today.
If your comparison period ends with your loan, nothing about your result changes. If you keep the freed-up EMI invested, the verdict does not change either, only the figures behind it, which now show each side holding what it actually holds. What does change is the other setting. Choosing not to reinvest used to stop every flow at payoff, which quietly gave the renter years of accommodation charged to nobody. Each path now pays its own housing from what it holds, and on the pre-filled figures as they stand today a thirty-year comparison moves from renting ahead to buying ahead.
One consequence is worth stating plainly: the toggle no longer picks the winner. Because the same budget governs both paths, it cancels out of the difference between them. What it changes is how much wealth each path keeps, and whether the renter's portfolio lasts. Where rising rent exhausts it, the calculator now names the year that happens, which on a long enough horizon is the most useful thing on the page.
Update, 30 July 2026: the starting numbers too
Correcting the calculations left one thing untouched: the figures each calculator opens with. We have since reset the starting numbers on every calculator, so all five now describe the same ₹80 lakh metro flat, and every uncertain figure sits in the middle of a published range rather than at the end of one that favours an answer.
A fresh look, and the same commitment
Alongside all of this, the site has a new design that loads quicker and reads better on a phone. But the change we care about most is not the one you notice first. Whether you are renting or buying, the calculators now hold both choices to the same standard: the same budget, the same horizon, and the true cost of each. That is the only way a comparison like this is worth anything.
