Calculate Allowed Rent Increase (Dubai RERA Method)
Enter your current annual rent and the RERA index annual rent estimate to see the maximum increase band commonly applied at renewal.
Rent renewal season can feel confusing, especially when tenant expectations and landlord expectations are not aligned. This RERA rent index calculator gives you a quick estimate of the allowed increase band based on widely used Dubai rental increase slabs. It is designed to support better conversations, clearer planning, and less friction when contracts are up for renewal.
What Is the RERA Rent Index?
The RERA rent index is a benchmark system used in Dubai to compare your current rent against typical market rent for similar properties. At renewal time, the difference between your rent and benchmark rent helps determine whether a landlord can request an increase, and by how much.
In practical terms, the index tries to prevent sudden, excessive increases while still allowing rents to move closer to market over time.
Increase Bands Used in This Calculator
This page uses common Decree 43-style rent increase bands. The gap is calculated as how far your current rent is below benchmark rent.
| Current Rent vs. Benchmark Rent | Maximum Increase |
|---|---|
| 0% to 10% below benchmark | 0% |
| More than 10% and up to 20% below benchmark | 5% |
| More than 20% and up to 30% below benchmark | 10% |
| More than 30% and up to 40% below benchmark | 15% |
| More than 40% below benchmark | 20% |
How to Use This Calculator Correctly
1) Enter your current annual rent
Use the amount stated in your active tenancy contract, not the monthly value. If needed, multiply monthly rent by 12 first.
2) Enter the benchmark (index) annual rent
Use the closest official benchmark for your unit profile. Accuracy matters because even a small difference can move your result into a different increase band.
3) Add notice period (optional)
If a rent increase is being proposed, notice timing can be crucial. This field helps you quickly check whether you are near the common 90-day expectation.
Why This Matters for Tenants and Landlords
- Tenants can budget realistically before renewal discussions.
- Landlords can set compliant increase expectations and avoid disputes.
- Agents and property managers can communicate policy-based numbers, not guesswork.
- Both sides can save time by anchoring negotiations to a shared benchmark.
Simple Example
Suppose your current annual rent is AED 80,000 and the benchmark/index value is AED 100,000:
- Your rent is 20% below benchmark.
- That usually falls in the 5% increase band (because increase starts after more than 10%).
- Maximum adjusted annual rent becomes AED 84,000.
- Monthly equivalent changes from AED 6,667 to AED 7,000.
Common Mistakes to Avoid
- Comparing with asking rents from listings instead of benchmark/index figures.
- Using a nearby building type that is not actually comparable.
- Forgetting that notice rules can affect enforceability of increases.
- Ignoring the latest legal updates and relying on old screenshots or hearsay.
Frequently Asked Questions
Does this guarantee the final legal rent?
No. This tool provides an estimate. Official systems, current regulations, and case-specific details determine the final enforceable position.
What if my current rent is already above benchmark?
The calculator will show no increase band. In that situation, an increase is generally not supported by index logic.
Can both parties still agree to something different?
Contract outcomes can involve negotiation. Still, parties should remain compliant with applicable law and formal process requirements.
Final Thoughts
A good rent discussion starts with transparent numbers. Use this RERA rent index calculator as your first pass, then verify your final figure through official channels. If the amount is significant or there is disagreement, consider taking professional legal or property advice before signing renewal documents.
