ROI and NPV in Real Estate: Judge Any Deal by Numbers
Two properties, two pitches, one question: which actually makes you more money? Feelings cannot answer that, but two numbers can. ROI tells you what a property earns on your investment, and NPV tells you what a stream of future income is truly worth today. This guide explains both, with worked examples, so you can judge any deal, from a commercial shop to an assured-return pitch, on arithmetic instead of adjectives.
What ROI means
ROI, Return on Investment, measures the annual return a property generates as a percentage of the total money you put in. The basic rental version is:
ROI = (Annual net rental income ÷ Total investment) × 100
Total investment means everything: price, stamp duty, registration, brokerage, fit-outs. Net income means rent minus the running costs, maintenance, property tax, and any CAM charges you bear.
A worked example: the commercial shop
Say you buy a shop for Rs 1 crore all-in, and it rents at Rs 55,000 a month, Rs 6.6 lakh a year. You bear Rs 60,000 a year in costs, leaving Rs 6 lakh net. ROI equals 6 lakh divided by 1 crore, which is 6 percent. Compare that against the typical bands: residential yields run roughly 2 to 4 percent, commercial roughly 6 to 9 percent, which is why income investors lean commercial, as our pre-leased property guide details. Total return adds appreciation on top: if the shop's value grows 5 percent that year, your combined return is meaningfully higher, though only the rent is cash in hand.
What NPV means
NPV, Net Present Value, answers a subtler question: what are tomorrow's rupees worth today? Money later is worth less than money now, because today's money could be earning elsewhere. NPV takes every future cash flow a property will produce, rents, and eventually a sale price, discounts each back to today at a chosen rate, and subtracts your investment. A positive NPV means the deal beats your benchmark return; a negative one means your money works harder elsewhere.
Why NPV catches what ROI misses
ROI treats every year's rupee as equal. NPV does not, and that difference exposes time-loaded promises. Consider an assured-return scheme paying 12 percent for three years, then possession of a unit of uncertain rental value. The early payouts look rich, but discounting shows how much of the pitch's value depends on those first cheques arriving, exactly the risk our assured return guide dissects. Likewise, a project delivering rent from day one can beat a cheaper one that starts earning three years later, and NPV is the tool that proves it. For discounting, Indian investors commonly use 8 to 10 percent, roughly the return safe alternatives offer.
Using both numbers like an investor
Use ROI as your quick filter: compute net yield on every candidate and discard the weak ones. Use NPV, a spreadsheet handles the formula, when comparing deals with different timing: under-construction versus ready, assured-return versus fresh-versus-resale routes, or a high-rent short lease versus a modest long one. And always sanity-check the inputs, real market rents, realistic vacancy, true all-in costs, because no formula survives flattering assumptions.
The mistakes that flatter the numbers
Most bad property math shares the same errors. Investors compute yield on the quoted price rather than the true all-in cost, ignoring stamp duty, brokerage and fit-outs, which inflates ROI by a full percentage point or more. They assume twelve months of rent every year, when even good assets sit vacant between tenants. They forget the costs that recur, maintenance, insurance, repairs, and the tax on rental income. And they count promised appreciation as if it were banked. The discipline is simple: compute on all-in cost, assume realistic vacancy of a month or so a year, subtract every recurring cost, and treat appreciation as a bonus rather than a base case. Numbers built that way survive contact with reality, and deals that still look good after such math usually are good.
Frequently asked questions
How do I calculate ROI for a commercial shop?
Divide the annual net rent, rent minus maintenance, tax and CAM you bear, by your total all-in investment, and multiply by 100. A Rs 1 crore shop netting Rs 6 lakh yearly returns 6 percent.
What is a good ROI in Indian real estate?
Residential rentals typically yield 2 to 4 percent, commercial 6 to 9 percent, before appreciation. Deals promising far above these bands deserve extra scrutiny, not extra excitement.
What is NPV in simple words?
Net Present Value converts all of a property's future income into today's rupees using a discount rate, then subtracts your investment. Positive NPV means the deal beats your benchmark.
What discount rate should I use for NPV?
Most Indian investors discount at 8 to 10 percent, reflecting what safe alternatives earn. Use a higher rate for riskier income streams like construction-period promises.
Why use NPV when I already have ROI?
ROI ignores timing; NPV prices it. When comparing deals whose incomes start at different times or carry different certainty, NPV reveals which is genuinely worth more today.
Does ROI include property appreciation?
Basic rental ROI does not. Total return adds the year's value growth to the rental yield, but treat appreciation as an estimate until a sale actually books it.
ROI filters, NPV decides, and together they turn property pitches into comparable numbers. Run both before any significant purchase, and let the arithmetic argue with the brochure. Our team can help you build the numbers for any deal on your shortlist.
