Enter your details to estimate the maximum allowable rent increase.
Note: This calculator provides estimates based on RTB Rent Pressure Zone rules as of June 2025. All of Ireland is an RPZ, with rent increases capped at 2% or HICP inflation (whichever is lower). Landlords must use the official RTB calculator and forms for compliance. Visit www.rtb.ie for official calculations and dispute resolution.

With a detailed results table and an interactive chart, you’ll gain clear insights into permissible rent adjustments.
A Rent Pressure Zone (RPZ) Calculator for Ireland is a critical tool for landlords and tenants, calculating the maximum allowable rent increase for properties in RPZs, as mandated by the Residential Tenancies Board (RTB). Since June 20, 2025, all private and student-specific tenancies in Ireland fall under RPZ rules. By inputting the current rent, date of last rent setting, and property Eircode, the calculator determines the permissible increase based on the Harmonised Index of Consumer Prices (HICP) or 2% annually, whichever is lower.
The formula is: New Rent = Current Rent × (1 + HICP or 0.02), applied every 12 months for new tenancies or 24 months for existing tenancies in newly designated RPZs. For example, a €1,500 rent with a 1.4% HICP since the last review (e.g., November 2024) yields a maximum new rent of €1,521. If HICP is negative (e.g., -0.2%), no increase is allowed.
Benefits include ensuring compliance, avoiding fines up to €15,000, and providing transparency for tenants. The calculator confirms RPZ status and shows amortization details. Exemptions apply for properties vacant for 2+ years, substantially renovated, or adapted for disability.
For accuracy, verify the last rent amount and date, use the correct Eircode, and check HICP values on RTB’s website. Test scenarios for different review dates. Consult the RTB or legal advisors for disputes. An RPZ Calculator ensures fair, compliant rent adjustments. Calculate your maximum rent today
Rent Pressure Zones (RPZs) are designated areas in Ireland where rent increases are capped to ensure affordability, as regulated by the Residential Tenancies Board (RTB). As of 2025, RPZ rules stipulate that rent increases are limited to the lower of:
2% per annum.
The Harmonised Index of Consumer Prices (HICP) rate.
RPZs apply in high-demand areas like Dublin, Cork, and Galway. Rent reviews can occur every 12 months, and increases must comply with the cap based on the time elapsed since the last review. Our RPZ Calculator Ireland helps you calculate the maximum permissible rent increase to stay compliant with RTB regulations.
