Rent increase calculator

The law first, honestly: there is no magic percentage

The most-searched version of this question — "how much can a landlord legally increase rent in India" — has an answer most pages avoid giving plainly: for ordinary private tenancies, the law fixes no percentage. The increase is whatever the rent agreement's escalation clause says, or whatever landlord and tenant agree at renewal. The familiar "10% every year" and "5% at each 11-month renewal" are market conventions, not statutes. The genuine legal boundaries sit elsewhere: old protected tenancies under state Rent Control Acts have their own restricted regimes; states with specific tenancy legislation impose notice and procedure requirements; and everywhere, an increase applied mid-term without a supporting clause is simply not enforceable — the agreement governs until it ends. First authority: your agreement. Second: your state's law. Anyone quoting a universal legal cap is repeating folklore.

What compounding does while nobody watches

Escalation is a compound-interest problem wearing a rental costume, and both sides routinely misjudge it. A ₹30,000 flat on a 10% clause is ₹48,315 in year five and ₹58,000-plus by year seven — roughly double inside eight years. The same flat at 5% reaches ₹38,288 in year five. Over a five-year tenancy, the gap between those two clauses is several lakhs of total rent — decided in one line of the agreement that most people negotiate for five minutes. The calculator above shows the year-by-year schedule and cumulative rent for exactly this reason: the negotiation should happen against the compounded number, not the innocent-sounding annual percentage.

The second projection matters just as much: the market CAGR line. Local rents in most Indian metros have historically grown in the low-to-mid single digits annually over long periods, with sharp localised exceptions (a new metro line, a tech-park opening). An escalation clause meaningfully above the local market's real growth rate doesn't produce extra income — it produces a tenancy that drifts above market until the tenant leaves, and a vacancy month costs 8%+ of annual rent immediately. Enter your honest local CAGR and the tool shows where clause and market diverge: that crossover year is, statistically, when good tenants start browsing listings.

Using the numbers on each side of the table

Landlords: price escalation to keep good tenants, not to win years one and two. A 5% clause that retains a paying tenant for six years beats a 10% clause that triggers a vacancy in year three — run both scenarios above and compare cumulative rent minus a vacancy month; the arithmetic is rarely close. Where the property is genuinely under market, the honest move is a reset at renewal with notice and a rationale (comparable listings), not a silent compounding clause a tenant discovers in year four. And check the renewal's side effects: rent crossing ₹50,000 monthly brings tenant-side TDS under 194-IB into play, and months-of-rent deposits scale — the deposit calculator covers that side. The rental yield calculator answers whether the asset itself is performing.

Tenants: compound the clause before signing, and negotiate the percentage with the same energy as the rent — it's worth more over the tenancy. A renewal demand above the agreement's clause is a negotiation, not an obligation; comparable listings are your evidence, and the landlord's alternative (a vacancy plus brokerage plus repainting) is your quiet leverage. Where a big jump is genuinely fair because the tenancy fell behind market, trading it for a longer lock-in or a capped future clause converts a loss into predictability.

For portfolio landlords and managers, the compounding problem multiplies: twelve tenancies with different clauses, renewal dates and notice periods is exactly the ledger that outgrows memory. EstateDeck's tenant and lease management tracks each agreement's escalation clause, renewal date and rent history — so increases apply per contract on schedule, notices go out on time, and the rent roll reflects reality instead of last year's spreadsheet.

Accuracy note: this is general information and arithmetic, not legal advice. Tenancy law varies by state and by the age and type of tenancy; for protected tenancies, commercial leases and disputes, your agreement and a local lawyer are the authorities.
