What Is the Rental Index Calculator?
The Rental Index Calculator is a free digital tool that compares your current rent against official market benchmarks established by the Dubai Land Department (DLD) and the Real Estate Regulatory Agency (RERA). It determines whether your landlord can legally increase your rent upon lease renewal—and by exactly how much.
Whether you're a tenant in , , , or , this calculator applies the same legally mandated percentage caps across all residential areas in the emirate.
Key Benefits:
- Instantly check if a proposed rent increase is within legal limits
- View the maximum allowable percentage based on your current rent
- Access calculations aligned with Dubai's Smart Rental Index 2025
- Make informed decisions before signing your renewal contract
Our calculator uses the official rent increase brackets from Decree No. 43 of 2013, the same framework applied by the Rental Dispute Settlement Centre when resolving landlord-tenant disagreements.

How the Rental Index Calculator Works
The calculator follows a straightforward methodology based on Dubai's official rent increase framework. Here's the step-by-step process:
Step 1: Determine Your Current Rent Position
Enter your exactly as stated in your Ejari contract. The calculator then compares this amount against the average market rent for similar properties in your area—data sourced from RERA's rental index.
Step 2: Calculate the Percentage Difference
The tool calculates how far your current rent falls below (or above) the market average. This percentage difference determines which rent increase bracket applies to your situation.
Step 3: Apply Decree No. 43 Brackets
Under Decree No. 43 of 2013, the maximum allowable rent increase depends on how much below market rate your current rent is:
| Current Rent vs. Market Average | Maximum Permitted Increase |
|---|---|
| Up to 10% below | 0% (No increase allowed) |
| 11% to 20% below market average | Up to 5% |
| 21% to 30% below market average | Up to 10% |
| 31% to 40% below market average | Up to 15% |
| More than 40% below market average | Up to 20% |
Important Notes
The 20% cap is absolute—landlords cannot increase rent beyond this limit in a single renewal period, regardless of how far below market rate you're paying. Additionally, any rent increase requires 90 days' written notice before the contract expiry date. Without proper notice, the lease automatically renews at the same rent.

Example 1: Two-Bedroom Apartment in Al Nahda
Scenario: Ahmed rents a 2-bedroom apartment in Al Nahda, Dubai. His current annual rent is AED 45,000. The RERA index shows the average rent for similar units in his area is AED 60,000.
Calculation:
- Difference from market: AED 60,000 − AED 45,000 = AED 15,000
- Percentage below market: (15,000 ÷ 60,000) × 100 = 25%
- Applicable bracket: 21% to 30% below → Up to 10% increase permitted
- Maximum new rent: AED 45,000 × 1.10 = AED 49,500
Result: Ahmed's landlord can legally increase the rent to a maximum of AED 49,500 per year. If the landlord requests AED 52,000, Ahmed can refuse and cite Decree No. 43 guidelines.
Example 2: Studio in Dubai Marina
Scenario: Sarah pays AED 68,000 annually for a studio apartment in Dubai Marina. The market average for similar studios is AED 72,000.
Calculation:
- Difference from market: AED 72,000 − AED 68,000 = AED 4,000
- Percentage below market: (4,000 ÷ 72,000) × 100 = 5.5%
- Applicable bracket: Up to 10% below → No increase allowed
Result: Since Sarah's rent is only 5.5% below the market average, her landlord cannot legally increase the rent at renewal. The lease must continue at AED 68,000.
Example 3: Villa in Arabian Ranches
Scenario: The Khalid family rents a 4-bedroom villa in Arabian Ranches for AED 150,000 annually. The market average for comparable villas is AED 280,000.
Calculation:
- Difference from market: AED 280,000 − AED 150,000 = AED 130,000
- Percentage below market: (130,000 ÷ 280,000) × 100 = 46.4%
- Applicable bracket: More than 40% below → Up to 20% increase permitted
- Maximum new rent: AED 150,000 × 1.20 = AED 180,000
Result: Even though the family pays significantly below market rate, the landlord can only increase rent by 20% (to AED 180,000)—not to the full market rate of AED 280,000. To assess whether purchasing makes financial sense given rising rents, use our rent versus purchase comparison tool.
The 90-Day Notice Requirement
Under Dubai tenancy law (Law No. 26 of 2007, amended by Law No. 33 of 2008), landlords must provide written notice at least 90 days before the lease expiry date to request any changes—including rent increases. If your landlord failed to send timely notice, the rent cannot be increased at renewal, and the contract automatically continues under identical terms.
Smart Rental Index Updates (2025)
Since January 2025, Dubai has implemented the Smart Rental Index, which uses AI-driven analytics and real-time transaction data. Unlike the previous annual updates, this system adjusts more frequently to reflect current market conditions. The index now also considers building-specific factors like maintenance quality, amenities, and a star rating system (1-5 stars).
Common Mistakes to Avoid
- Accepting verbal agreements: Always get rent increase proposals in writing
- Ignoring late notices: Landlords who notify you after the 90-day window cannot enforce increases
- Not checking the official index: Verify all proposals against RERA's calculator before agreeing
- Confusing market rent with maximum rent: Just because market rent is AED 100,000 doesn't mean your landlord can charge you that amount—the cap structure still applies
Expert Tips
Run your calculation 100-120 days before renewal to give yourself negotiating room. If an increase is permitted, consider proposing a longer lease term (2 years) in exchange for a lower percentage increase. Always save a screenshot of your calculator result—it serves as evidence if you need to escalate matters to the Rental Dispute Settlement Centre.
