Rent vs Buy: Running the Numbers Honestly

"Renting is throwing money away." You've heard it a thousand times. It's also frequently wrong. Both renting and buying involve paying for shelter — they just structure the costs differently. Here's how to compare them without the folklore.

The honest monthly comparison

Take a representative example: an ₹80 lakh apartment, funded with ₹16 lakh down payment and a ₹64 lakh home loan at 8.75% for 20 years (EMI ≈ ₹56,900), versus renting a similar home for ₹25,000/month.

• Buyer's true monthly cost: EMI ₹56,900 + maintenance ~₹4,000 + property tax amortised ~₹1,200 ≈ ₹62,100 — of which only part builds equity early on (in year one, roughly ₹14,000–₹15,000 of each EMI is principal; the rest is interest).
• Renter's equivalent: rent ₹25,000, leaving ₹37,000/month potentially investable if the rent-vs-buy gap is actually invested rather than absorbed by lifestyle.

That last clause does the heavy lifting. Renting only wins financially when the difference is systematically invested. Spent, it's just a more expensive lifestyle.

The down-payment opportunity cost

That ₹16 lakh doesn't vanish into the flat — it converts into equity. But it also stops doing whatever else it could have done: equity funds historically compounding well over long periods, or simply staying liquid for emergencies and opportunities. Meanwhile ownership locks you into one city's job market and one building's fate. Liquidity has real, hard-to-price value — until the month you need it, when it prices itself very clearly.

Hidden costs of owning

• Stamp duty + registration: typically 5–7% upfront — ₹4–5.5 lakh on this purchase before you've moved in.
• Maintenance & repairs: painting, plumbing, society sinking funds — budget ~1% of property value per year over time.
• Property tax, forever.
• Transaction friction: buying and selling each cost lakhs in fees and months of effort, which punishes short holding periods.

When buying clearly wins

• You'll stay put 7+ years — long enough to outgrow the entry transaction costs and let principal repayment compound.
• You have stable income and the EMI fits comfortably inside the 40% rule (see our EMI guide).
• Your city's rental yields are low and rents are rising fast relative to prices (true across most Indian metros).
• You value security, freedom to modify your home, and forced savings discipline — worth something real.

When renting clearly wins

• Horizon under ~5 years, or career mobility is likely (renters relocate for better salaries; owners hesitate).
• The down payment would consume your entire safety net.
• You're disciplined about investing the difference — then compounding works for the portfolio instead of the building.

The decision framework

Answer four questions: (1) Will I stay 7+ years? (2) Does the EMI fit inside 40% of income after all existing EMIs? (3) Is my emergency fund intact after the down payment? (4) Am I buying the specific home I want, not just "a house" because of social pressure? Four yeses — buy with confidence. Two or fewer — keep renting and keep building toward it. The in-between cases deserve their own careful math.
