1. What is the RTB Rent Calculator?

The RTB (Residential Tenancies Board) Rent Calculator determines the maximum allowable rent increase in Rent Pressure Zones (RPZs) in Ireland, based on the Harmonised Index of Consumer Prices (HICP) rate, capped at 2% per annum.

2. How Does the Calculator Work?

The calculator uses the RTB formula:

Where:

• Current Rent — The existing rent amount in euros
• HICP Rate — The annual percentage change in the Harmonised Index of Consumer Prices
• 0.02 — The 2% cap on annual rent increases in RPZs

Explanation: The calculator applies the lower of either the HICP rate or 2% to calculate the new maximum allowable rent.

3. Importance of Rent Pressure Zone Rules

Details: These rules help stabilize rental markets in areas with high demand, preventing excessive rent increases while allowing for moderate adjustments based on inflation.

4. Using the Calculator

Tips: Enter current rent in euros and the HICP rate as a percentage (e.g., 1.5 for 1.5%). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are Rent Pressure Zones?
A: RPZs are designated areas in Ireland where rents can't increase by more than 2% per annum or the HICP rate, whichever is lower.

Q2: How often can rent be increased in RPZs?
A: Rent can only be increased once every 12 months in RPZs, subject to the 2% cap.

Q3: Where can I find the current HICP rate?
A: The Central Statistics Office (CSO) publishes the HICP rate for Ireland monthly.

Q4: Does this apply to all rental properties?
A: No, only to properties in designated Rent Pressure Zones and not to new tenancies in the first year.

Q5: What if my landlord tries to increase rent by more?
A: Any increase above the calculated amount in an RPZ may be invalid, and you can dispute it with the RTB.
