Rent in Mumbai or buy in Navi Mumbai: the monthly maths

“Rent is money down the drain.” Your parents say it. So does the colleague who bought across the harbour. And on the first of every month, when the rent leaves your account, part of you agrees.

Here’s what they leave out. For the same flat, rent is usually the smaller bill. Buying that home would cost you more each month, at least for the first few years.

So the honest question isn’t which is cheaper. It’s what the extra buys your family, and whether you can carry it.

The short answer: moving across the harbour can bring the loan payment near your rent, but buying needs far more cash up front.

For that you get a home you own, a payment that doesn’t rise at every renewal, and the choice to stay near your child’s school. Renting keeps your savings free, and lets you move.

Start with your own rent, because no index knows your street

No public index tracks Mumbai rents area by area, so your rent receipt is the best number you have.

Across the whole city, Square Yards puts the average rent at ₹114 for every square foot of floor, every month, as of September 2026. On a 650 sq ft flat, that’s about ₹74,100.

So we’ll carry one example rent through: ₹50,000 a month. Still deciding whether to leave Mumbai? Start with why Mumbai families look at Navi Mumbai.

Your rent, paid to a bank instead, repays this much loan

Turn your rent into an EMI (the fixed amount you’d pay the bank monthly) to see what home it reaches.

We’ve used an example rate of 8.5% over twenty years. SBI’s home loans now run from about 7.5% to 8.8%, after its rise on 15 October 2026. Your credit score decides where you land.

Lenders follow RBI’s loan-to-value limits, which go by loan size: up to 90% for loans up to ₹30 lakh, 80% up to ₹75 lakh, 75% above. The rest is your down payment, in cash.

Example rent a month	Loan that EMI repays	Home it reaches	Down payment
₹35,000	₹40.3 lakh	₹50.4 lakh	₹10.1 lakh
₹50,000	₹57.6 lakh	₹72 lakh	₹14.4 lakh
₹70,000	₹80.7 lakh	₹1.08 crore	₹26.9 lakh

In the middle row, a ₹50,000 rent repays the loan on a ₹72 lakh home, once you’ve found the down payment.

Does ₹72 lakh go far? In Panvel, 47 of 54 projects start at or under that price. In Kharghar, 28 of 78 do. A starting price is usually a building’s smallest home, often a 1 BHK.

What Navi Mumbai’s starting prices cost a month

Now the other way round, area by area.

Panvel, ₹27.82 lakh₹21,700

Kharghar, ₹36 lakh₹26,000

Nerul, ₹90 lakh₹62,500

Seawoods, ₹99 lakh₹65,100

Vashi, ₹1.34 crore₹87,200

Each bar takes the biggest loan allowed. Kharghar’s is ₹30 lakh; Seawoods’ is ₹75 lakh, the cap.

The cheapest homes are the exception, though. A typical Kharghar project starts at ₹1.02 crore, and its EMI is nearer ₹66,700.

At our example rent, most of Panvel fits. In Kharghar, only about a third does. Nerul, Seawoods and Vashi ask for more.

What does that typical Kharghar gap mean in your month? About ₹16,700 more than the example rent. Would it come out of the school fees, the travel pass or a parent’s medicines?

On the other side, a 2 BHK can give your child a room of their own. One of you may also have a longer trip to work, so time it at your own hour before you decide.

A year’s rent is about 4.3% of a flat’s price; a loan costs about 8.5%

Anarock puts Mumbai’s gross rental yield at 4.3% for April to June 2026. That’s a year’s rent as a share of the flat’s price.

Take one ₹1 crore flat. At that yield, it would rent for about ₹36,000 a month.

Buying it with a 75% loan means an EMI of about ₹65,100, at our example rate over 20 years. So for the same flat, the monthly rent is often well below the EMI. The landlord’s other hope is that the flat gains value, which nobody can promise.

Only part of an EMI is a cost

“But an EMI builds something, and rent doesn’t.” Partly true. It depends on which part of the EMI you mean.

Early on, most of each payment is interest. On the loan in that middle row, year one’s EMIs add up to ₹6 lakh. Only about ₹1.15 lakh of that pays off the loan.

That part is yours, like savings locked in the walls. The other ₹4.85 lakh or so is interest. So set your rent against the interest and the maintenance, not the whole EMI. Then add one thing people forget.

Your down payment stops earning. SBI pays 6.40% on a two-year deposit. On ₹14.4 lakh, that’s about ₹92,000 a year you give up, before tax.

The first year asks a buyer for far more cash

First year	Renting at ₹50,000	Buying a ₹72 lakh home
Cash up front	Deposit of 3 to 6 months: ₹1.5 to ₹3 lakh, and it comes back	Down payment: ₹14.4 lakh, and it stays in the flat
Paperwork	A small stamp duty and fee on the agreement	Stamp duty and registration on the price, in cash
Twelve months	Rent: ₹6 lakh	EMIs: ₹6 lakh, plus society maintenance
Interest you give up	Small: only the rent deposit sits idle	About ₹92,000 on the down payment

Stamp duty (the state’s tax on registering a property) is the buyer’s big extra. No bank lends for it, so it’s cash on top. Our stamp duty guide for Navi Mumbai works out your bill.

Maintenance varies, so ask the society for its bill. A renter pays a small stamp duty and registration fee on the agreement; check the state’s IGR site.

Rent climbs each year, and an EMI can move too

Rent can rise at renewal, and that’s the part of renting you can’t plan.

Mumbai rents rose 10.3% in the year to March 2026, the latest we checked, by the Magicbricks rental index. Navi Mumbai’s rose nearly 10%.

If yours kept rising at that pace, which is an example and not a forecast, our example rent would become about ₹55,150 next year.

Rents can cool, too. In the year to March 2026, Mumbai’s flats on offer grew 21.6% while demand slipped.

An EMI doesn’t rise yearly like rent, but most home loans float. The Reserve Bank lifted its repo rate (the rate banks borrow at) to 5.50% on 7 October 2026. Here’s what that rise does to your EMI.

Tax changes the sum only in the old regime

Your tax regime changes this, so check with your CA. In the new regime, there’s no deduction for home-loan interest or principal on a home you live in, and house rent allowance is fully taxed.

In the old regime, renters can claim part of that allowance. Owners can claim interest up to ₹2 lakh a year, under section 22 of the Income-tax Act 2025, by one source.

A flat still being built means rent and EMI together

Most new projects here are still being built. So for a while, you’d pay rent and the loan together.

Until the keys, banks charge pre-EMI: interest only on the part of the loan already paid to the builder. How many months could you carry it beside your rent?

Three examples. Each date is the possession month (when the builder must hand over the keys) on MahaRERA, the state’s register of approved projects.

• Anant Serene Park, Panvel: 1 and 2 BHK from ₹33.5 lakh, possession December 2026, next month: ask for its occupancy certificate date.
• Gami Ved, Nerul: 1 and 2 BHK from ₹90 lakh, possession December 2027.
• Sai Proviso Atlantis, Kharghar: 2 BHK from ₹45.99 lakh, possession December 2028.

Take Sai Proviso Atlantis: on its 2 BHK start, the loan would be about ₹36.8 lakh.

Once the bank has paid all of it out, pre-EMI at our example rate is about ₹26,000 a month, on top of your rent. It starts smaller, growing as the bank pays the builder.

After the keys, the full EMI is about ₹31,900.

A registered date is the builder’s promise, not your moving day. Check MahaRERA for any extension, and budget rent until the building has its OC (the certificate that says it’s safe to live in).

Keep renting, or buy: who each one suits

Why that line? Lenders often accept 40% to 55% of income going to loans. We’d stay at the low end, so school fees still fit. Seven years is our own rule of thumb, long enough to spread the stamp duty; your rent and price move it.

The simple rule: buy when three things are true. You’ll stay seven years or more, the cash is saved without touching your emergency fund, and the EMI fits in about 40% of take-home. Until then, renting is a sound choice, not a failure.

So take your own rent, not our example, and put it in the EMI check on this page, with our guide to buying a flat in Navi Mumbai beside it. Then let’s look at one real home together, at your number.

Questions buyers ask

Is it better to rent or buy a house in Mumbai?

It depends on how long you’ll stay. For the same flat, renting is usually cheaper a month. Buying can make sense over time if you stay put and the EMI fits comfortably. Renting suits a shorter stay.

Is an EMI always more than rent?

Not for a cheaper home here. The bigger gap is the cash up front.

How much down payment do I need?

Usually 20% of the price, 25% once the loan passes ₹75 lakh, and 10% on a loan of ₹30 lakh or less. Stamp duty and registration come on top, in cash.

How we checked: the EMIs, loans, down payments and interest are our own arithmetic, at an example 8.5% over 20 years. Starting prices, counts and possession months come from our project pages, read 7 November 2026.
