Dubai rent increase calculator — checked against the RERA scale, 2026

Dubai Rent Increase Calculator 2026 — RERA cap check

Key points

  • The ceiling comes from Decree No. 43 of 2013 and turns on one thing — how far your rate lags the average market rate: under 10% means no increase at all, 11–20% allows up to 5%, 21–30% up to 10%, 31–40% up to 15%, and more than 40% up to 20%.
  • The average market rate is not taken from portal listings but from the official index — the Dubai REST calculator, tied since 2025 to the rating of the specific building.
  • The landlord must give written notice of an increase at least 90 days before the contract ends (Law No. 26 of 2007 as amended by Law No. 33 of 2008, Art. 14). Miss that, and the increase does not apply: the contract renews on the old terms.
  • If the demand exceeds the ceiling and talks go nowhere, the dispute goes to the Rental Dispute Centre at the Dubai Land Department.
  • The calculator runs the general scale and works as a check. The final answer rests on the rate the index assigns to your building.

Your landlord has sent a new figure and is waiting for a signature. He cannot raise the rent by whatever he likes: the ceiling is set by Decree No. 43 of 2013 and depends on one thing only — how far your rate has fallen behind the market. Enter three amounts and the calculator shows the permitted percentage, the lawful maximum, and whether the demand fits inside it.

An estimate under the scale of Decree No. 43 of 2013. The ceiling is measured against the average market rate for comparable housing, not against how the area feels to you: check a disputed figure in Dubai REST. A separate ground for objecting is notice served later than 90 days before the contract ends.

What the result means

The calculator measures the gap between your current rent and the average rate for similar housing. The further you are below the market, the more the landlord may add. A gap under 10% blocks any increase, no matter how many years you have lived there or how much the area has risen.

The number that decides everything is the average market rate, and that is the one most often swapped out. A landlord will point to neighbours' listings or to new contracts in the building, but only the official index carries weight. The scale, the Smart Rental Index and the notice rules are set out in the main guide, "Landlord raising the rent: is it legal and how to challenge it".

If the demand exceeds the ceiling

Start with the date of the notice. If the letter arrived later than 90 days before the contract ends, the percentage is beside the point: the contract renews on the old terms. Then show the landlord the index calculation. That usually ends the conversation, because the figure is verifiable and there is nothing to argue with.

If he insists, the dispute goes to the Rental Dispute Centre at the Dubai Land Department, and the separate guide covers filing, documents and the fee. Complaints about an agent's licence or a management company go a different route, through RERA and the DLD. Do not move out or sign a new contract "while we sort this out": a signature under the new rate settles the question of whether it was lawful.

FAQ

Where do I get the average market rate for the calculation?

From the official Dubai REST calculator, the Dubai Land Department's app and portal. It gives a range for your area, property type and size. Since 2025 the DLD has been moving to the Smart Rental Index, where the rate is tied to the rating of a specific building, so check your address rather than the district in general.

The landlord says prices in the area rose 40%, so the rent goes up 40% too?

No. A rising market only feeds into the calculation through the average market rate, while the increase itself is capped by the scale: 20% at most, and only when your current rent lags the market by more than 40%.

What if I already pay at or above market?

Then no increase is allowed: a gap under 10% gives a ceiling of 0%. The calculator prints that on its own line.

Is the ceiling measured against the amount the landlord is asking?

No, only against your current rent under the running contract. The demanded figure is there for comparison with the lawful maximum, and nothing else.

Can I agree to more than the ceiling voluntarily?

The parties are free to agree a new contract, and a signed one will hold. So do not sign a new rate before you have checked the calculation: after the signature it becomes far harder to challenge.

How accurate is the calculator?

It runs the scale of Decree No. 43 of 2013 and is enough to test a landlord's demand. The one place the figures can diverge is the average rate the index assigns to your building. In a dispute, go by the Dubai REST reading on the day you check.
