"Rent is money down the drain" has probably driven more Indian financial decisions than any other sentence — and it is an accounting error. Interest, maintenance, property tax and stamp duty are money down the same drain; only principal builds anything. Whether buying beats renting is a real question with a computable answer, and the answer swings on assumptions most people never state out loud.
The only fair comparison
The honest method compares terminal net worth on two fully-specified paths. The buyer's path counts everything: down payment, stamp duty and registration, the EMI, maintenance (about 1% of the home's value a year), property tax, and selling costs at the end. The renter's path counts rent, its annual escalation — and, crucially, investing every rupee the buyer sinks and the renter does not: the down payment and stamp duty on day one, plus each year's difference between ownership outgo and rent. Leave that investment leg out and buying always looks free; it is the mistake that settles most dinner-table versions of this argument. The rent vs buy calculator runs both paths this way.
Two inputs dominate the outcome:
- Property appreciation. The single most sensitive assumption. At high single digits, buying usually wins; at inflation-like appreciation, renting and investing usually does. Whoever picks this number picks the answer, so interrogate it — a city-wide average is not your building's future.
- Rental yield. In Indian metros, annual rent runs at roughly 2–4% of price — remarkably low by world standards. The rental yield calculator turns an asking price and rent into a yield; if the flat you would buy rents at 2.5%, you are choosing between paying 2.5% to occupy it and paying EMI-plus-costs to own it.
What the spreadsheet cannot hold
Two omissions are deliberate, one on each side. Owning carries security and optionality — no landlord can evict you, renovation is yours to decide — that never appear in a terminal value. Renting carries flexibility worth actual money to a career that may move cities. Price these yourself; just price them consciously, instead of letting "down the drain" do it for you.
Tax has switched sides quietly: home-loan relief under 24(b) and 80C is old regime only. Under the new regime — the default — a self-occupied buyer gets nothing, which alone flips many answers older calculators still show as favouring purchase. See choosing your tax regime.
Selling, one day
The exit has its own tax chapter: gains on property held over two years are long-term, with the rules rewritten in July 2024 — for older purchases the computation can still involve indexation, and reinvestment exemptions (s.54 and kin) can shelter gains rolled into another home. The property capital gains calculator handles the regimes and the CII arithmetic. Factor the 2% or so of selling costs the terminal value already charged you.
⚠️ Stamp duty varies by state, tax rules by Budget, and both change. The calculator's model — 1% maintenance, 2% selling costs, old-regime-only relief — is stated so you can argue with it. Verify current figures before a decision this size; WealthTicker is not a SEBI-registered investment adviser.
Key takeaway
Compare terminal net worth with the renter investing every rupee the buyer sinks — down payment, stamp duty and the yearly outgo gap — or you have not compared anything. The answer hinges on the appreciation you assume and the rental yield you actually face, home-loan tax relief no longer exists under the default regime, and both "rent is wasted" and "property always appreciates" are slogans, not analysis.

Cost to company is what employing you costs, not what you are paid. The four layers inside a CTC, where EPF and gratuity actually go, and the basic-salary split that silently sets three benefits at once.
Old vs new tax regime: the choice that decides everything else
The new regime is the default and usually the winner — but not always. Where the break-even sits, why the §87A rebate never touches capital gains, and why the regime decides whether ELSS, HRA and 80D planning are worth anything at all.
Advance tax and TDS: how India collects before you file
TDS is a running prepayment, not the final bill, and advance tax fills the gap in four dated instalments. The 15/45/75/100 calendar, the cliff in the early triggers, and the presumptive shortcut that collapses it to one March payment.
ESOPs, RSUs and ESPPs: taxed twice, at two different prices
Slab tax on the discount when shares become yours, capital gains from that day's FMV when you sell. Why tax can fall due on paper value, and why the cost-basis error is the most common mistake in self-filed returns with equity comp.

Presumptive taxation lets a qualifying professional declare half of gross receipts as profit — no books, no audit, one advance-tax instalment. How the scheme works, and how to compare a salary and a freelance offer honestly.
How an EMI actually works (and the flat-rate trick)
Interest on the outstanding balance first, principal with the remainder — so early years barely repay anything. Why tenure sets total interest, why early prepayment punches above its weight, and why a flat rate is roughly double what it claims.
A surplus and a loan: prepay, refinance or invest?
Prepayment is a guaranteed, tax-free return equal to your loan rate — cut the tenure, not the EMI. When a balance transfer clears its fees, and when investing the surplus honestly beats both.
