What Is the RERA Rental Increase Calculator?
The RERA Rental Increase Calculator, now shown through Dubai Land Department’s Rental Index service, is the official Dubai tool used to check whether a rent increase is allowed at renewal. It compares your current annual rent with the relevant market benchmark from the rental index, then applies the rent increase limits set by Dubai’s rent increase rules. For tenants, it is the fastest way to check whether a proposed renewal rent is legal. For landlords, it is the safest way to avoid sending an above-cap renewal demand.
For the 2026–2027 rental cycle, the key point is that the calculator should be treated as the source of truth before you negotiate. A portal listing, a neighbour’s rent, an agent’s opinion, or a landlord’s expected return does not replace the official DLD result. The result can still depend on the data entered: Ejari contract number, DEWA premise number, contract end date, area, building, property type, bedroom count, rental index type, and current annual rent. If one field is wrong, the output may be wrong.
The calculator answers one question: what is the maximum rent increase allowed by the index and cap rules? It does not by itself prove that the landlord served the required renewal notice on time. A landlord may have a calculator result allowing 5%, 10%, 15%, or 20%, but if the rent increase notice was not given at least 90 days before expiry, the tenant may still reject the increase for that renewal cycle.
Where to Access the Calculator in 2026–2027
- Use Dubai Land Department’s Rental Index eService.
- Good for desktop users who want screenshots or PDF records.
- The page includes fields such as DEWA premise number, Ejari contract number, area, building name, property type, bedrooms, contract end date and current annual rent.
- Use this route if you are preparing an RDC file and want clean screenshots.
- Useful for tenants and landlords who already manage Ejari or property services through Dubai REST.
- Login requirements may depend on the service and user status.
- Best for quick checks while discussing renewal with an agent.
- Always save the result page and the input details used.
- Keep your Ejari certificate, contract, notice and calculator result together.
- If the landlord disputes your screenshot, rerun the calculation using the same official input fields.
- For serious disputes, use official DLD and RDC channels rather than informal third-party calculators.
- Third-party calculators are helpful for planning only.
Pro tip: Before opening the calculator, keep your Ejari certificate, tenancy contract, DEWA premise number, current annual rent and contract end date ready. Most wrong results come from entering the wrong bedroom count, area/building name or annual rent.
What to Prepare Before You Start
The official calculator works only as well as the information you enter. Do not guess your rent, expiry date, or area name from memory. Open your signed tenancy contract and Ejari certificate first. The current annual rent should be the rent stated in the contract, not the monthly payment after splitting cheques, and not a separate DEWA, chiller, furniture, parking, or maintenance charge unless that amount is part of the registered rent.
- Ejari certificate or Ejari contract number.
- Signed tenancy contract.
- Contract start and end dates.
- Current annual rent amount.
- Landlord’s proposed new rent notice.
- DEWA premise number if using that lookup.
- Residential, commercial, industrial or staff accommodation.
- Apartment, villa, office, retail, warehouse or other sub-type.
- Area or community name as DLD lists it.
- Building name or complex details.
- Number of bedrooms or room type.
- Contract end date for the renewal cycle.
- Date landlord sent rent increase proposal.
- Method: email, WhatsApp, registered mail, letter or Notary.
- Exact proposed rent amount.
- Whether notice was at least 90 days before expiry.
- Any reply you already sent.
- Proof that you are ready to pay the lawful amount.
Step-by-Step: How to Use the RERA Calculator
Open the official Rental Index service
Go to the Dubai Land Department Rental Index service or open the relevant rental index option in Dubai REST. Avoid relying only on screenshots from agents. The official DLD route is the one you should use when a dispute is possible.
Choose the lookup method
The DLD service can show different input routes. Depending on the property and service path, you may see options such as Ejari Contract Number, DEWA Premise Number, area/building lookup, or complex search by land number or municipality number. Use the most specific option available. Ejari or DEWA data is usually better than guessing the area manually.
Enter the contract end date
The contract end date tells the calculator which renewal cycle is being checked. Use the expiry date on your tenancy contract. Do not use the date you moved in, the date you signed, or the date the landlord sent notice.
Select the correct rental index type and property type
Choose whether the property is residential, commercial, industrial or another category. Then select the correct property type and unit details. Apartment and villa benchmarks are not the same. Retail, office and warehouse calculations may use different fields.
Enter the current annual rent
This is the most important manual field. Enter the current yearly rent shown in your contract. If you pay in four cheques, do not enter one cheque amount. If your contract includes separate chiller, furniture or parking charges, check whether those amounts are actually part of the registered rent before including them.
Click calculate and read the result
The result will show the rental index output and the permitted increase result. Save the result immediately. If the landlord’s proposed rent is above the maximum result, you have a clear basis to reply. If the result allows an increase, still check whether the landlord served the 90-day notice on time.
Save your evidence
Take a screenshot or download the result if the service allows it. Save the screenshot with the date, input fields and result visible. For a dispute file, store it with your Ejari, tenancy contract, landlord notice, and written reply.
What Each Calculator Field Means
Ejari Contract Number
A fast lookup option if the system can retrieve registered tenancy data. It reduces errors because property details should match the contract record.
DEWA Premise Number
A property-linked number that can help identify the unit. The DLD page currently indicates a 9-digit DEWA premise number field.
Contract End Date
The lease expiry date for the renewal cycle. This is separate from the notice date and should match your tenancy contract.
Area, Building and Property Type
These fields identify the correct market benchmark. Manual selection errors can change the output, so use exact DLD names where possible.
Current Annual Rent
The yearly rent being paid under the current contract. This is used to calculate how far your rent is below the index benchmark.
Average Market Rent / Benchmark
The comparison value from the rental index. Your current rent is measured against this figure to choose the Decree 43 tier.
Permitted Increase
The maximum percentage increase permitted for that renewal cycle, assuming the landlord also served any required notice on time.
RERA / Decree 43 Rent Increase Matrix
Dubai’s rent increase matrix is based on how far the current rent is below the average rental value. The official Decree 43 structure uses five bands: 0%, 5%, 10%, 15% and 20%. The calculator applies this logic automatically, but understanding the bands helps you explain the result to an agent or landlord.
| Current Rent Compared With Average Market Rent | Maximum Increase | Simple Example | What It Means |
|---|---|---|---|
| Less than 10% below average | 0% | Rent AED 95k, benchmark AED 100k | No increase allowed because the rent is close to market. |
| 11% to 20% below average | 5% | Rent AED 85k, benchmark AED 100k | Small increase may be allowed. |
| 21% to 30% below average | 10% | Rent AED 75k, benchmark AED 100k | Moderate increase may be allowed. |
| 31% to 40% below average | 15% | Rent AED 65k, benchmark AED 100k | Higher increase may be allowed. |
| More than 40% below average | 20% | Rent AED 55k, benchmark AED 100k | Maximum cap tier applies. |
⚠️ Timing still matters: A calculator result allowing an increase does not fix a late notice. If the landlord did not give the required renewal notice on time, the tenant can raise a separate Article 14 timing objection.
Smart Rental Index and Building Classification
Dubai’s Smart Rental Index was launched by Dubai Land Department as a more transparent rental valuation system. Instead of relying only on broad area averages, the system considers building-level and market information. Public reporting and DLD announcements describe a classification approach that considers multiple factors such as location, building classification, rental contract values in the building and average values in the area.
For tenants, this means two buildings in the same community may not always produce the same benchmark. A newer, better-maintained tower with stronger facilities can have a higher benchmark than an older building nearby. For landlords, it means upgrades, maintenance, security, amenities and building quality can matter more than before. For disputes, it makes the official calculator result more important because the benchmark may be more specific than a simple neighbourhood average.
- Condition and age of the building.
- Maintenance quality and common areas.
- Facilities such as gym, pool and security.
- Building classification where available.
- Rental contract values in the building.
- Average rental values in the area.
- Unit type and bedroom count.
- Recent rental market behaviour.
- Use exact building and contract details.
- Do not rely only on area averages.
- Save the official result date.
- Recheck near renewal if timing changes.

Tenant Reply Template for an Above-Cap Increase
A short written reply is better than a long argument. Attach the calculator screenshot and state the exact legal amount you are willing to pay.
Sample:
Dear [Landlord/Agent], thank you for your renewal proposal. I checked the official Dubai Land Department Rental Index / RERA calculator using my property details and current annual rent of AED [current rent]. The result shows the maximum permitted renewal rent is AED [maximum rent]. Your proposed rent of AED [proposed rent] appears to exceed the official cap by AED [difference]. I am ready to renew at AED [maximum rent], subject to the renewal being completed through Ejari. Please confirm the corrected renewal amount. Regards, [Name].
Landlord Checklist Before Sending a Renewal Increase
Landlords should run the official calculator before sending a rent increase notice. This avoids wasting the 90-day notice window on an amount that cannot be enforced. A clear proposal should include current rent, proposed rent, percentage increase, contract expiry date, notice date and the calculator basis. If you send the notice too late, or propose too much, the tenant has a stronger position at RDC.
- Run the official DLD Rental Index calculation.
- Check Decree 43 tier and maximum rent.
- Confirm contract expiry date.
- Prepare notice at least 90 days before expiry.
- Use the correct tenant and unit details.
- State the exact proposed annual rent.
- Attach or reference the calculator result.
- Use written notice with date proof.
- Keep email headers or delivery receipt.
- Do not rely on phone calls only.
- Recheck input fields with the tenant.
- Correct any calculation error.
- Negotiate within the legal cap.
- Accept lawful renewal cheques.
- Use RDC only when documents support your position.
Common Mistakes When Using the RERA Calculator
- Entering monthly rent instead of annual rent.
- Including DEWA, chiller or housing fee as rent.
- Using the proposed rent as current rent.
- Using an old contract amount that is no longer active.
- Selecting apartment instead of villa.
- Choosing the wrong community name.
- Using area-level data when building data is available.
- Selecting the wrong bedroom count.
- Thinking the cap is a guaranteed increase.
- Ignoring the 90-day notice requirement.
- Relying on third-party results over DLD.
- Forgetting to save evidence before filing.
Worked Examples: How to Read RERA Calculator Results
Many tenants understand the calculator result better when they see real numbers. The examples below use the Decree 43 percentage bands and show how the legal maximum rent is calculated. The same principle applies for 2026–2027: start with the current annual rent, compare it with the benchmark, identify the tier, then check whether the landlord’s proposed rent is within the maximum. Do not skip the 90-day notice check.
| Current Rent | Benchmark Rent | Gap | RERA Tier | Max Legal Rent | Landlord Asks | Status |
|---|---|---|---|---|---|---|
| AED 95,000 | AED 100,000 | 5% below | 0% | AED 95,000 | AED 100,000 | Above cap |
| AED 85,000 | AED 100,000 | 15% below | 5% | AED 89,250 | AED 90,000 | Slightly above cap |
| AED 75,000 | AED 100,000 | 25% below | 10% | AED 82,500 | AED 82,000 | Within cap |
| AED 65,000 | AED 100,000 | 35% below | 15% | AED 74,750 | AED 80,000 | Above cap |
| AED 55,000 | AED 100,000 | 45% below | 20% | AED 66,000 | AED 66,000 | Within cap |
These examples also show why “market rent” is not the same as “new rent.” Even if the benchmark is AED 100,000, a tenant currently paying AED 75,000 does not automatically jump to AED 100,000. The legal increase is limited by the tier. In that example, a 10% increase makes the maximum legal rent AED 82,500, not AED 100,000. This is where many landlord proposals go wrong.
2026–2027 Renewal Timeline: When to Use the Calculator
The RERA calculator should be used before renewal negotiations become urgent. Waiting until the final week creates pressure and makes it harder to collect documents. Use the timeline below if your contract expires in 2026 or 2027.
120–150 days before expiry
Open your current tenancy contract, check the expiry date, and run a first calculator check. This gives you a planning number before the landlord sends a proposal. Landlords should use this period to prepare any increase notice and verify that the requested amount is within the official cap.
At least 90 days before expiry
This is the key renewal notice window. If the landlord wants to change rent or terms, the written notice should be served before the deadline unless the contract validly says otherwise. Tenants should save any notice immediately and calculate the day count.
60–90 days before expiry
If a notice was received, run the DLD calculation using exact inputs and compare it with the landlord’s amount. If the proposed rent is above cap, reply with the official result. If the notice was late, reply about the timing issue and offer renewal at the current rent.
30–60 days before expiry
Try to settle the renewal in writing. Tenants should prepare cheques or payment proof for the lawful amount. Landlords should avoid refusing payment without a clear legal basis, because refusal can become evidence in a renewal dispute.
Final 30 days
If no agreement is reached, organise an RDC file. Include the DLD calculator result, tenancy contract, Ejari, landlord notice, your reply, payment readiness, and all communication. Keep paying undisputed rent and avoid emotional messages.
RDC Evidence Checklist for Above-Cap Rent Increases
If the landlord refuses the official calculator amount, the dispute is usually document-based. The Rental Disputes Centre will not need a long story if the documents clearly show the rent, notice, calculation and refusal. Prepare the file before you escalate.
- Signed tenancy contract.
- Ejari certificate.
- Current annual rent proof.
- Contract expiry date.
- Payment receipts, cheque copies or bank transfers.
- Any renewal addendum from previous years.
- Landlord’s rent increase notice with date.
- Delivery proof or email/WhatsApp timestamp.
- DLD Rental Index calculator screenshot.
- Input fields used in the calculation.
- Your written reply rejecting the excess amount.
- Any counteroffer from landlord or agent.
- Cheques prepared for lawful renewal rent.
- Bank transfer readiness screenshot where relevant.
- Message offering payment on time.
- Landlord refusal or silence.
- Proof you did not abandon the contract.
- Calendar of all key dates.
A strong file shows that the tenant is not refusing to pay. It shows that the tenant is refusing only the unlawful excess. That difference matters. A tenant who simply says “I will not pay” may create risk. A tenant who says “I am ready to pay AED X because the official calculator confirms AED X is the maximum” is in a much better position.
Common 2026–2027 Disputes and How to Handle Them
Landlord says the building was upgraded
Building upgrades can affect market value, but the rent increase still needs to fit within the official calculator result and notice rules. Ask the landlord to run the DLD Rental Index calculation using the updated building data. If the official result allows an increase, negotiate within that cap. If the landlord wants more than the cap, ask for a corrected proposal.
Agent says the calculator is only guidance
For Dubai rent increase disputes, the official DLD calculator is not just casual guidance. It is the reference used to determine whether an increase is within the legal framework. If an agent says the landlord can ignore it, ask them to provide the legal basis in writing. Most agents will soften their position once asked to put the claim in writing.
Tenant entered the wrong current rent
If the tenant enters the wrong current annual rent, the output can be misleading. Always use the signed contract and Ejari record. If the Ejari amount differs from the actual signed contract, do not rely blindly on either figure; collect payment proof and get advice before filing.
Landlord served notice on time but used the wrong property type
Sometimes a landlord’s calculator result is wrong because the property was entered as a villa instead of an apartment, the wrong bedroom count was selected, or the wrong community was chosen. The best response is not to accuse the landlord immediately. Rerun the calculator together using the correct fields and save the new result.
