Renting against buying, with the opportunity cost included
Why comparing rent to EMI is the wrong comparison, what the price-to-rent ratio tells you quickly, and the costs that only appear on one side.

In short
- Comparing rent to EMI is meaningless. Part of an EMI is savings; all of a rent is expenditure — and buying has costs an EMI never shows.
- The price-to-rent ratio is the fastest screen. Below 15 favours buying, above 25 favours renting, and most Indian metros sit above 30.
- The down payment has an opportunity cost. ₹20 lakh invested at 10% is ₹2 lakh a year that buying gives up.
- Transaction costs of 8% to 12% on the way in and 1% to 2% on the way out mean a short holding period almost always favours renting.
- Buying wins on a long horizon, in a stable location, when the price-to-rent ratio is reasonable. Two of those three are about you, not the market.
The usual version of this question — "my rent is ₹35,000 and the EMI would be ₹43,000, so buying is only slightly worse" — compares two things that are not comparable, and leaves out most of what decides the answer.
Why rent against EMI is the wrong comparison
An EMI is part interest and part principal. The interest is a cost, exactly like rent. The principal is savings — you are buying part of an asset.
But buying also carries costs that never appear in the EMI: maintenance, property tax, society charges, insurance, and the return you gave up on the down payment.
The honest comparison is:
Cost of renting = rent + the return you earn on the money you did not put into a house.
Cost of buying = interest + maintenance + property tax + society charges + insurance + opportunity cost of the down payment + amortised transaction costs, minus the appreciation in the property's value.
Principal repayment appears on neither side, because it moves money from one pocket to another rather than spending it.
The price-to-rent ratio
Before doing any of that, one number screens the decision quickly:
price-to-rent = property price ÷ annual rent
A ₹1,20,00,000 flat renting at ₹35,000 a month — ₹4,20,000 a year — has a ratio of 28.6.
| Ratio | Reading |
|---|---|
| Below 15 | Buying is usually clearly better |
| 15 – 20 | Buying is generally favourable |
| 20 – 25 | Balanced; the details decide |
| Above 25 | Renting is usually better |
Most Indian metros sit between 30 and 50, and parts of Mumbai and Bengaluru go higher. A ratio of 40 means the annual rent is 2.5% of the price — a rental yield well below what the same money earns in a deposit, before any of the costs of ownership.
That is the arithmetic reason renting looks favourable in Indian cities, and it holds unless prices are expected to rise substantially.
What each side actually costs
Take a ₹1,20,00,000 property, a ₹24,00,000 down payment, a ₹96,00,000 loan at 8.5% over 20 years, and rent of ₹35,000 rising 7% a year.
Buying, first year:
| Item | Amount |
|---|---|
| Interest (approximately) | ₹8,09,000 |
| Maintenance at 1% of value | ₹1,20,000 |
| Property tax | ₹15,000 |
| Insurance | ₹8,000 |
| Opportunity cost on ₹24 lakh at 10% | ₹2,40,000 |
| Transaction costs, amortised over 10 years | ₹1,20,000 |
| Total annual cost | ₹13,12,000 |
Renting, first year: ₹4,20,000.
Against that, the property may appreciate. At 6% a year, ₹1.2 crore gains ₹7,20,000 — which brings the net cost of buying to about ₹5,92,000 against ₹4,20,000 of rent.
The whole answer therefore turns on the appreciation assumption, and that is the least knowable input in the model. At 4% appreciation buying is clearly worse; at 8% it is clearly better. Indian residential prices have averaged roughly 4% to 6% over the last decade in most cities, well below the 10% to 15% of the previous one.
Transaction costs and the break-even period
Buying costs money at both ends.
On the way in, 8% to 12% of the property value: stamp duty at 5% to 8%, registration, brokerage, legal fees, and the loan processing fee. On ₹1.2 crore that is ₹10 lakh to ₹14 lakh.
On the way out, 1% to 2% of brokerage plus capital gains tax on the profit, which is 12.5% long-term without indexation or 20% with it, depending on the option chosen.
Those costs are recovered over the holding period, so the longer you stay the smaller the annual bite. The usual break-even is five to seven years in a market appreciating at 5% to 6%, and longer where appreciation is weaker.
The corollary is direct: if there is a real chance of moving within five years, rent. A job change, a transfer, a city you are not sure about, or an uncertain relationship all point the same way, and the transaction costs will not be recovered.
What renting genuinely buys
Mobility. Thirty days' notice against a sale taking three to twelve months.
Liquidity. The down payment stays invested and accessible. Property is the least liquid asset most people own, and it cannot be sold in part.
No maintenance risk. A failed lift, a leaking roof or a society special assessment is the owner's problem.
Diversification. Buying puts most of a household's net worth into one asset, in one city, tied to one local economy — frequently the same economy their job depends on. That concentration is rarely acknowledged as a risk and is a large one.
What buying genuinely buys
A fixed housing cost. The EMI is stable while rent rises 5% to 10% a year. Over twenty years that is the largest financial argument for buying, and it compounds.
Forced saving. Principal repayment is a savings habit that requires no discipline. Someone who would not have invested the difference is better off owning, and that describes most people honestly.
No landlord. Renting in India means annual increases, deposits of six to eleven months in some cities, restrictions on alterations and pets, and the possibility of being asked to leave.
An asset at the end. After twenty years the owner has a paid-off property and the renter has whatever they invested, which is a real comparison only if they actually invested it.
The two questions that usually decide it
The arithmetic rarely produces a landslide, and when it does not, two non-financial questions do.
How long will you stay? Under five years, rent. Over ten, buying is usually better on most reasonable assumptions. Between the two, the arithmetic matters.
Would you actually invest the difference? The rent-versus-buy comparison assumes the renter invests the down payment and the monthly saving. Most do not, and the mortgage's forced saving is worth more than a spreadsheet says.
Everything else — appreciation, rates, tax treatment — is genuinely uncertain and moves the answer less than these two.
The tax position, which changed
Home loan tax benefits used to be a substantial part of the case for buying in India. For most people they no longer are.
Under the old regime, a self-occupied property allows up to ₹2,00,000 a year of interest under section 24(b), and principal repayment counts inside the ₹1,50,000 of section 80C. In the 30% bracket that is worth up to ₹1,05,000 a year.
Under the new regime, which has been the default since 2023-24, neither is available. A taxpayer who has moved to the new regime — as most have, because it is cheaper without large deductions — gets no tax benefit from a home loan at all.
House rent allowance works the other way. It is exempt under section 10(13A) in the old regime and not in the new one, so both sides of the comparison lost their concession at the same time.
The practical effect is that the rent-versus-buy decision in India is now closer to a pure economic comparison than it has been for two decades. Run the numbers without any tax benefit unless you have specifically stayed in the old regime.
Buying to let
A third option sits between the two and is often assumed to combine their advantages.
Rental yields in Indian metros run 2% to 3.5% gross, before maintenance, vacancy, property tax and the cost of finding tenants. Net yields of 1.5% to 2.5% are typical. Against a home loan at 8.5%, a leveraged rental property has a negative carry that only appreciation can rescue.
Rental income is taxed at slab rate after a standard 30% deduction for maintenance and after loan interest, and losses set off against other income are capped at ₹2,00,000 a year.
None of that makes it a bad investment — appreciation and leverage together can work well — but it is an investment decision that should be evaluated against alternatives, not a housing decision. The two get conflated constantly.
What this calculator assumes
- Rent rises at the rate you set; property appreciates at the rate you set. Both are assumptions, and the result is more sensitive to appreciation than to anything else.
- The opportunity cost of the down payment is applied at the investment return you specify.
- Maintenance is estimated as a percentage of property value, typically 0.5% to 1% a year.
- Transaction costs are amortised across the holding period rather than charged in year one.
- Tax deductions on home loan interest are not applied by default, since they are unavailable under the new regime.
