Property or SIP Over 20 Years? The Answer Turns on 1.5 Percentage Points
The comparison circulating online puts a studio flat against an equity SIP and declares a winner by nearly ₹87 lakh. Rebuild it with the missing pieces and the gap narrows sharply, because the investor still has to pay rent and the buyer still has to find a down payment.
A version of this comparison reaches most Indian phones every few months. Take a ₹35 lakh home loan at 8.5%, note the EMI of ₹30,374, then put the identical amount into an equity SIP at 12% instead. The property side ends around ₹80 lakh of net wealth, the SIP side around ₹1.67 crore, and the conclusion writes itself.
It is a useful question badly answered. Two things go wrong: one is arithmetic, and one is a missing person. Fix both and the answer is still interesting, just far less dramatic, and it depends on a single number most people never think to check.
Quick Summary
A ₹30,374 monthly SIP at 12% for 20 years is worth about ₹3.00 crore, not ₹2.40 crore. But the SIP investor also pays rent for those 20 years, and the buyer pays a down payment and stamp duty the comparison ignores. Modelled properly, the investor still finishes ahead by roughly ₹1.33 crore on central assumptions, and buying overtakes investing once property appreciation runs within about 1.5 percentage points of the equity return.
What We Know: the market inputs that are not assumptions
Before modelling anything, it is worth separating the published record from the guesswork.
- Equity has compounded at roughly 12% over 20 years, on a total return basis. NSE Indices reported the Nifty 50 Total Return Index at 12.44% annualised for the 20 years ended February 2026, against 11.09% for the price return index.
- House prices have compounded far slower. National Housing Bank Residex data indicates that ₹1 lakh in residential property 20 years ago grew to about ₹4.4 lakh, a compound annual growth rate of roughly 7.7%.
- Rental yields are low by global standards. Gross residential yields in Indian metros mostly run between 2.5% and 4%, with Mumbai lowest and Delhi and Kolkata highest on median stock. Net yield is typically 0.5 to 1 percentage point below gross once maintenance, tax and vacancy are counted.
- Home loans are cheaper than the viral example assumes. With the repo rate at 5.25% after 125 basis points of cuts through 2025, published 2026 rates for strong credit profiles run around 7.10% to 7.65%, well below the 8.5% used in the shared version.
- Both exits are taxed at the same headline rate. Long-term capital gains on listed equity and on property are both taxed at 12.5%, with equity carrying a ₹1.25 lakh annual exemption and property taxed without indexation under the Finance Act 2024.
The arithmetic slip: ₹2.40 crore is not what 12% produces
Start with the number that is simply wrong. A monthly investment of ₹30,374 compounded at 12% a year for 240 months comes to about ₹3.00 crore, not ₹2.40 crore. The lower figure is what you get at roughly 10.5%.
Check the EMI, then check the SIP
The EMI figure in the shared version is correct: ₹35 lakh at 8.5% over 240 months does produce an EMI of ₹30,374 and a total outgo of ₹72.90 lakh, of which ₹37.90 lakh is interest. It is the investment side that has been understated. Whenever you meet one of these comparisons, recompute both legs before accepting either.
The missing person: someone still has to pay rent
The larger flaw is not arithmetic at all. If you buy the flat, you live in it. If you put the EMI into a SIP instead, you have a growing portfolio and nowhere to sleep. The comparison silently gives the investor free accommodation for two decades.
On a ₹43.75 lakh flat at a 3.5% gross yield, rent starts at about ₹12,760 a month. Growing at 5% a year it reaches roughly ₹32,245 a month by year 20 and totals about ₹50.63 lakh over the period. That is money the investor pays out and the owner does not, and it has to come off the SIP.
The buyer has an omission of their own, in the opposite direction. A ₹35 lakh loan at 80% loan-to-value implies a ₹43.75 lakh property and an ₹8.75 lakh down payment, plus stamp duty and registration of roughly 7%, or ₹3.06 lakh. That is ₹11.81 lakh paid on day one, which the investor gets to put to work as a lump sum.
These two omissions push in opposite directions, which is why the popular version is not simply wrong by a fixed amount. Adding rent to the investor’s side hurts the SIP. Adding the down payment and stamp duty to the buyer’s side hurts the property. Whether the corrected gap is wider or narrower than the advertised one depends entirely on which effect is larger, and that in turn depends on rental yield, on stamp duty in your state, and on how much of the price the bank was willing to lend.
There is a third omission that almost never appears. A flat is not free to hold. Society maintenance, property tax, insurance and the occasional month between tenants come to roughly 0.8% to 1% of the property’s value every year, rising as the value rises. Over 20 years on this flat that is a substantial sum, and in an honest comparison it belongs on the buyer’s side of the ledger and in the investor’s SIP.
Rebuilding it honestly: the assumptions on the table
Here is the model, stated in full so anyone can disagree with a specific line rather than the conclusion. Two people need the same flat. One buys it; the other rents it and invests every rupee of the difference, including the upfront costs the buyer had to find.
| Input | Value used | Buyer | Renter-investor | Basis |
|---|---|---|---|---|
| Property price | ₹43.75 lakh | Buys it | Rents the same flat | ₹35 lakh loan at 80% LTV |
| Upfront cost | ₹11.81 lakh | Pays it | Invests it as a lump sum | Down payment plus 7% duty |
| Loan | 8.5%, 20 years | EMI ₹30,374 | Invests the same monthly | Matches the shared example |
| Rent | 3.5% yield, plus 5% a year | Pays none | ₹12,760 rising to ₹32,245 | Metro yield range |
| Ownership costs | 0.8% of value a year | Pays them | Invests the equivalent | Maintenance, tax, vacancy |
| Growth rates | 7% property, 12% equity | Flat appreciates | Portfolio compounds | Near historical averages |
On these inputs the investor ends with about ₹2.99 crore against the buyer’s ₹1.66 crore after a 2% cost of sale, a difference of roughly ₹1.33 crore. Substituting the loan rate actually available in 2026, around 7.65%, narrows the gap to about ₹1.15 crore, because a cheaper loan lowers the EMI and therefore the amount the investor gets to invest.
The number that decides it: a 1.5 point rule
Running the same model across a grid of assumptions produces something more useful than any single answer. Buying wins whenever property appreciation comes within roughly 1.5 percentage points of the equity return, and the relationship holds remarkably steadily across the range.
| Property appreciation | Equity at 9% | Equity at 10.5% | Equity at 12% | Equity at 13.5% |
|---|---|---|---|---|
| 5% a year | Investing by ₹64 L | Investing by ₹114 L | Investing by ₹179 L | Investing by ₹263 L |
| 6% a year | Investing by ₹42 L | Investing by ₹93 L | Investing by ₹158 L | Investing by ₹243 L |
| 7% a year | Investing by ₹17 L | Investing by ₹67 L | Investing by ₹133 L | Investing by ₹219 L |
| 8% a year | Buying by ₹14 L | Investing by ₹37 L | Investing by ₹103 L | Investing by ₹189 L |
| 9% a year | Buying by ₹51 L | Level | Investing by ₹67 L | Investing by ₹153 L |
Why property stays closer than the raw returns suggest
The obvious question is how a 7% asset ever competes with a 12% one. The answer is leverage. The buyer controls a ₹43.75 lakh asset having put down ₹11.81 lakh, so the appreciation applies to the whole property while only a quarter of the money is theirs. The investor’s 12% applies only to money actually invested.
That amplification is also why the break-even gap stays near 1.5 points rather than widening. It is real, and it cuts both ways: leverage magnifies a fall as efficiently as a rise, and unlike a SIP you cannot pause an EMI when the market turns.
The leverage advantage also decays as the loan is repaid. In the early years the buyer controls the full asset on a small slice of equity, which is why the year-five gap in the chart above is narrow. By year fifteen most of the loan is gone, the buyer is effectively an unlevered owner of a 7% asset, and the portfolio compounding at 12% pulls away. Anyone quoting a five-year version of this comparison will therefore reach a very different conclusion from anyone quoting a twenty-year one, and both can be arithmetically correct.
The single biggest driver is not in the property at all
Across the whole grid, moving the equity assumption from 9% to 13.5% swings the outcome by around ₹200 lakh. Moving property appreciation from 5% to 9% swings it by about ₹110 lakh. Anyone presenting one of these comparisons has chosen both numbers, and the choice of equity return is doing most of the arguing.
Five things even this model leaves out
- Tax at exit. Both assets attract 12.5% long-term capital gains, so the headline rate is a wash, but equity gains can be harvested annually within the ₹1.25 lakh exemption while a flat is sold once, in one lump.
- Rental income and its deductions. The model assumes the buyer lives in the flat. Letting it out adds income taxed at slab after a 30% standard deduction, and interest deductions differ sharply between the two tax regimes.
- Behaviour. An EMI is compulsory and a SIP is not. A meaningful share of people who plan to invest the difference simply spend it, and for them the forced saving of a home loan is worth more than any model shows.
- Liquidity and lumpiness. You cannot sell one bedroom to fund a medical emergency. Selling a flat takes months, costs brokerage, and often happens at whatever price is available rather than the price on paper.
- Concentration. One flat in one micro-market is a single undiversified bet on one local economy, one builder and one title. An index fund is not.
A home you live in is not primarily an investment
The comparison is a fair test of a second property bought to build wealth. It is a poor test of a first home, which also delivers security of tenure, freedom from landlords and rent inflation, and something no spreadsheet captures. Treat the numbers as an input to that decision, not a verdict on it.
What Is Still Unclear
Four things genuinely cannot be settled, and they are the ones any confident comparison quietly hides.
- Whether 12% is the right equity assumption. The Nifty 50 total return index has delivered 12.44% over 20 years to February 2026, but the 20-year rolling price CAGR dipped below 10% during FY26, only the second such episode in the index’s history. The number moves with the measurement date.
- What your specific property will do. Residex measures a national index. Individual flats in individual buildings diverge enormously from it, and no index tells you about your builder or your corridor.
- Where rents go. The 5% escalation used here is conventional. Sustained rent growth above that would materially favour the buyer, and below it, the investor.
- Interest rates over 20 years. The loan is modelled at a fixed rate. Most Indian home loans are floating and linked to the repo rate, which has moved 125 basis points in a single year recently.

Frequently asked questions
Is a mutual fund SIP better than buying property over 20 years?
On central assumptions, yes, but by less than the popular comparisons claim. Modelled properly, with the investor paying rent and the buyer paying a down payment and stamp duty, a renter-investor finishes around ₹1.33 crore ahead of a buyer over 20 years at 7% property appreciation and 12% equity returns. Change either growth rate and the answer can flip, and the model says nothing about the non-financial value of owning a home.
What does a ₹30,000 monthly SIP become in 20 years?
A SIP of ₹30,374 a month, which is the EMI on a ₹35 lakh loan at 8.5% for 20 years, grows to about ₹3.00 crore at 12% a year. At 10.5% it is ₹2.46 crore, at 13% it is ₹3.44 crore and at 9% it is ₹2.03 crore. Total contributions across the period are ₹72.90 lakh. The spread across those return assumptions is ₹1.41 crore on identical contributions.
At what point does buying property beat investing in equity?
On this model, when property appreciation comes within about 1.5 percentage points of the equity return. Against a 12% equity assumption, buying overtakes investing above roughly 10.5% annual appreciation. Against 9% equity, the break-even is about 7.6%. The gap stays near 1.5 points because leverage lets the buyer earn appreciation on the full property value while putting down only part of the money.
What is a realistic property appreciation rate in India?
National Housing Bank Residex data implies roughly 7.7% a year over 20 years, meaning ₹1 lakh became about ₹4.4 lakh. Individual markets diverge widely, and some metro corridors have recorded double-digit annual gains in recent years. Sustaining that for two decades is a different proposition from recording it for two years, and a national index tells you nothing about a specific building.
Does rental income change the comparison?
Less than most people expect, because Indian residential gross yields sit at roughly 2.5% to 4% in the metros and net yields land 0.5 to 1 percentage point lower after maintenance, property tax and vacancy. Rent is taxed at slab after a 30% standard deduction. Rental income matters, but it is a modest contributor next to capital appreciation, which is what property investors are really betting on.
How are property and equity gains taxed on exit?
Both attract long-term capital gains at 12.5%. Listed equity carries an annual exemption of ₹1.25 lakh on long-term gains, while property is taxed without indexation under the Finance Act 2024, with a limited option to use the older 20%-with-indexation route for properties acquired before 23 July 2024. Because the headline rate matches, tax is not the deciding factor here, though the ability to stagger equity redemptions is a modest advantage.
Should I buy my first home or rent and invest?
The arithmetic in this article tests a second property bought for wealth creation. A first home also buys security of tenure, protection from rent inflation and freedom from a landlord’s decisions, none of which a spreadsheet prices. If a home loan is also the only way you would reliably save, the forced discipline of an EMI can outperform a SIP you would not actually maintain. Use the numbers as one input among several.
Are home loan rates lower in 2026?
Yes. Following 125 basis points of repo rate cuts through 2025 and a repo rate of 5.25%, published 2026 home loan rates for borrowers with strong credit profiles run around 7.10% to 7.65%, against 9% or more in early 2024. Any comparison built on an 8.5% loan is using a stale input. A lower rate reduces the EMI, which helps the buyer but also reduces the sum the alternative investor gets to put to work.
The short version
The viral answer is directionally right and quantitatively unreliable. The SIP figure is understated by about ₹60 lakh, the investor is given free housing for 20 years, and the buyer’s ₹11.81 lakh of upfront cost goes unmentioned. Correct all three and the investor still finishes ahead, by roughly ₹1.33 crore on central assumptions rather than the ₹87 lakh usually quoted, which is a bigger gap arrived at by a fairer route. The finding worth carrying is the break-even: property has to appreciate within about 1.5 percentage points of what equity returns before buying wins, and leverage is why it gets that close at all. Whether your flat clears that bar over the next 20 years is not something anybody, on either side of this argument, actually knows.
