This comprehensive guide explains everything: the rera index calculator, the new Smart Rental Index, how to calculate rent increases, service charges, and how the rera calculator works for 2026, 2025, 2024, and historical years.

What is a RERA Calculator?

The rera calculator is an official online tool that allows both tenants and landlords to check whether a proposed rent increase is legal according to Dubai’s rental laws. The rera rental index calculator dubai compares your current rent with the average market rent for similar properties in the same area and determines the maximum percentage your landlord can raise the rent at renewal.

The rera rent calculator is based on the RERA Rental Index, which is updated periodically to reflect current market conditions. In 2025, RERA introduced the Smart Rental Index, an AI-powered system that provides more accurate, building-level valuations.

Smart Rental Index: The 2025-2026 Update

In 2025, the Dubai Land Department officially replaced the traditional calculator with the Smart Rental Index. This system uses artificial intelligence and real-time data from Ejari registrations to determine fair rental values. The Smart Rental Index Dubai classifies buildings on a 1-5 star scale based on factors like building condition, amenities, and maintenance history. This means two identical apartments in the same community can now have different rent caps. The system is fully operational in 2026 and provides more accurate and transparent rental valuations.

How to Calculate Rent Increase Using the RERA Calculator

The rera rental increase calculator uses a tiered system based on how much your current rent is below the market average. The rera rental increase calculator dubai works as follows:

Gap Between Current Rent & Market Average	Maximum Legal Increase
0% – 10% below market	0% (No increase allowed)
11% – 20% below market	Up to 5%
21% – 30% below market	Up to 10%
31% – 40% below market	Up to 15%
More than 40% below market	Up to 20%

The rera rent increase calculator enforces a strict 20% cap, regardless of how far your rent is below market.

How to Use the Official RERA Calculator Online

The rera calculator online is free and accessible to everyone. Follow these steps:

Visit the Dubai Land Department website (dubailand.gov.ae) and go to “e‑Services”.
