Key Takeaways
- The RERA Rental Calculator is an official Dubai Land Department (DLD) tool that shows the maximum allowed rent increase at renewal.
- Since January 2025, it's powered by the Smart Rental Index, which uses AI and real-time data instead of annual surveys.
- Rent increases are capped at 0%, 5%, 10%, 15%, or 20% if your current rent is below the market average.
- The caps only apply to lease renewals, not new tenancy agreements.
What Is the RERA Rental Calculator?
The RERA Rental Calculator, officially called the Rental Index Calculator, is an e-service provided by the Dubai Land Department (DLD) under RERA. It compares your current annual rent against the official market benchmark for similar properties in your area.
After that, it applies the rent increase law to notify landlords and tenants if a rent increase is permitted and what the maximum percentage is when renting in Dubai.
Before the Smart Rental Index launched in January 2025, the calculator relied on data updated roughly once a year. Now it pulls from real-time Ejari transaction records, building quality classifications, and AI-driven analytics, making it significantly more accurate and building-specific than its predecessor.
Who Should Use the RERA Rental Calculator?
This tool isn't just for tenants bracing for renewal season. Both sides of a lease negotiation have every reason to run the numbers before sitting down at the table.
For Tenants
If your landlord has sent a rent increase notice, the calculator tells you within minutes whether the increase is legal. If your current rent is at or close to the market average, you may be entitled to zero increase — regardless of what your landlord proposes. It also helps you decide whether to negotiate, renew, or look elsewhere — a decision that's easier to make when you know what ideal rent looks like in Dubai for your unit type.
For Landlords and Property Owners
The calculator protects you, too. Setting rent too far above the legal cap risks a dispute filing at the Rental Dispute Settlement Centre. Using the tool before issuing a renewal notice ensures you stay compliant, maintain a professional relationship with your tenant, and avoid unnecessary delays. If you're managing multiple units, tools like a rent tracking dashboard can help you keep renewals and legal caps organised across your entire portfolio.
For Investors
If you're evaluating a rental property's yield or planning a new listing price, the Smart Rental Index gives you verified market benchmarks. That's far more reliable than estimating from listings alone. Our guide on rental cash flow in Dubai explains how to factor these benchmarks into your return projections.
The Legal Framework: Decree No. 43 of 2013
The RERA Rental Calculator helps with the rent increase law in Dubai. Decree No. 43 of 2013 defines the rent increase caps based on a single metric: how far your current rent sits below the market average for comparable properties, as per the rental laws in Dubai.
Rent Increase Bands
The 90-Day Notice Rule
Even if a rent increase is legally permitted, the landlord must deliver written notice at least 90 days before the lease expiry date. Miss that window, and the increase cannot be applied — the tenant has the right to renew at the existing rent.
This is one of the most commonly overlooked rules on both sides of a lease. Understanding the full scope of these protections is part of knowing your rights and responsibilities as a tenant in Dubai.
Old RERA Index vs. Smart Rental Index: What Changed in 2025?
The calculator you use today on the DLD website is no longer the same tool it was a year ago. In January 2025, the DLD replaced the annual RERA Rental Index with the Smart Rental Index, a real-time, AI-powered system that marks a significant upgrade in accuracy and transparency.
What's Different
The old index used broad area-level averages updated once a year. The Smart Rental Index now pulls live data from Ejari registrations, factors in building-specific classifications (covering more than 60 criteria, including maintenance quality, parking, amenities, and security), and updates continuously rather than annually.
In practice, this means the market benchmark for your specific building can now be more accurate than a generic neighbourhood average, which matters a lot if your building is significantly better or worse maintained than others in the area.
What Stayed the Same
The rent increase percentage bands haven't changed. The 90-day notice requirement hasn't changed. And the tool is still accessed through the same official DLD portal and Dubai REST app. The Smart Rental Index simply makes the benchmark calculation more precise, which is good news for both tenants who were being measured against inflated neighbourhood averages and landlords who were previously limited by outdated data.
How to Use the RERA Rental Calculator: Step by Step
You can access the calculator directly on the Dubai Land Department website or through the Dubai REST mobile app (available on iOS and Android).
Step 1: Visit the Official Tool
Go to DLD Rental Index, or open the Dubai REST app and select "Inquiry about the Rental Index."
Step 2: Select Your Service Type
Choose "Inquiry about the Rental Index" and click "Access This Service."
Step 3: Enter Your Property Details
You'll need:
- Contract end date
- Property type (Apartment, Villa, Commercial, etc.)
- Area or community (e.g., Dubai Marina, JVC, Downtown Dubai)
- Number of bedrooms (Studio, 1BR, 2BR, etc.)
- Current annual rent in AED
Optional fields that improve accuracy:
- Ejari contract number
- DEWA account number
Step 4: Calculate
Hit "Calculate" and review the result. The tool will show you the market average for comparable units, how your rent compares as a percentage, and the maximum increase your landlord is legally permitted to apply.
Step 5: Act on the Result
If the result shows 0%, your landlord cannot legally raise your rent. If it shows an increase band, that's the ceiling you can negotiate against. If your landlord's proposal exceeds what the calculator shows, it's not compliant with RERA regulations and you have grounds to challenge it.
A Practical Example
Say you're renting a 2-bedroom apartment in Jumeirah Village Circle at AED 75,000 per year. You run the calculator, and the Smart Rental Index shows the average for comparable units in your building is AED 95,000.
Your rent is approximately 21% below the market average, which falls in the 21–30% band. That means your landlord can legally increase rent by up to 10%, bringing your new rent to a maximum of AED 82,500.
If your landlord proposes AED 90,000, you now have an official, government-issued number to negotiate with.
Frequently Asked Questions
Does the RERA rental cap apply to new leases?
No. The legal caps only apply at renewal for existing tenancy contracts. For new leases, rent is market-driven and agreed between landlord and tenant. The Smart Rental Index can still serve as a useful benchmark when negotiating a starting rent, but there's no legal ceiling that applies.
If the rent increase is higher, you can negotiate or ask the landlord for monthly rent instalments. Also, you can apply for Rent Now, Pay Monthly by Keyper. Eligibility and conditions apply.
Can a landlord increase rent mid-contract?
No. Rent can only be adjusted at the point of renewal and at most once every 12 months. Mid-contract increases, unless specifically agreed and documented in the original lease, are not permitted under Dubai law.
What if my current rent is above the RERA market average?
If your rent is already at or above the average benchmark in the Smart Rental Index, your landlord cannot legally apply any increase at renewal. In this case, the calculator result will show 0%. You can use this as leverage to keep your rent stable or even negotiate a modest reduction, though landlords are not legally required to lower it.
Managing lease renewals, rent increases, and tenant communications across multiple properties is exactly where a structured system pays dividends. Keyper's property management software keeps everything — contracts, notices, renewal timelines — in one place, so nothing falls through the cracks when renewal season arrives.
