1. What is the RTB Rent Increase Calculator?

The RTB (Residential Tenancies Board) Rent Increase Calculator helps landlords and tenants determine the maximum allowable rent increase in Rent Pressure Zones (RPZs) in Ireland, based on current regulations.

2. How Does the Calculator Work?

The calculator uses the RPZ formula:

Where:

• \( Old\ Rent \) — The current monthly rent amount
• \( 1.02 \) — 2% annual increase limit in RPZs
• \( HICP \) — Harmonised Index of Consumer Prices rate
• \( Market\ Rent \) — Current market rent for similar properties (if known)

Explanation: The rent can only increase by the lower of 2% or the HICP rate, and never above the market rent for similar properties in the area.

3. Rent Pressure Zone Rules

Details: Rent Pressure Zones are areas where rents are highest and rising, with special rules limiting rent increases to 2% per year or the HICP rate, whichever is lower.

4. Using the Calculator

Tips: Enter your current rent in euros, the current HICP rate (default is 1.2%), and optionally the market rent if known. The calculator will show the maximum allowed new rent.

5. Frequently Asked Questions (FAQ)

Q4: Are all properties in RPZs covered?
