The answer, live

Enter the rent and the two dates — the ceiling, the governing rules and the arithmetic appear here as you type.

Cross-check the figure with the RTB's official calculator at rtb.ie — but note it applies the current rules: for review notices served under earlier regimes, the law in force at service governs, and the current calculator can give the wrong answer for legacy reviews.
