Free calculators for buying and renting a home in Ireland
ClearHome.ie has 5 free calculators covering the real costs and rules of buying or renting a home in Ireland — stamp duty, Help to Buy and the First Home Scheme, rent increase limits, the Rent Tax Credit, and tenancy notice periods. Every result shows where the figures come from and when they were last checked, so you can trust the number, not just the tool.
Buying a home
Rent vs Buy Calculator
Compare the real cost of renting and buying the same home over time, including mortgage payments, fees, home value growth, and what your deposit could earn if invested instead.
Total Cost of Buying a Home Calculator
Work out the full cash you need to buy a home in Ireland: stamp duty, legal fees, deposit, and how Help to Buy or the First Home Scheme reduce what you need upfront.
Renting
Rent Increase Calculator
Check the maximum legal rent increase for your tenancy under Ireland's nationwide rent control rules — 2% or inflation, whichever is lower, with the new-build exception explained.
Rent Tax Credit Calculator
Find out how much you can claim back through the Rent Tax Credit, based on the rent you paid and whether you're claiming as a single person or jointly assessed couple.
Notice Period Calculator
Work out the minimum legal notice period for ending a residential tenancy in Ireland, for either a tenant or a landlord, based on how long the tenancy has lasted.
Why trust the numbers
Sourced, not guessed
Every rate and rule links back to Revenue, the RTB, or another official source — shown directly on the result, not buried in a footnote.
Dated, so you know it's current
Each calculator shows when it was last reviewed, and old rates are kept (not deleted) so changes are auditable when rules update on Budget day.
Ireland-specific
Built around Irish stamp duty bands, RTB notice rules, and Revenue tax credits — not a generic calculator adapted after the fact.

- Yes, every calculator on ClearHome.ie is free, with no sign-up required. The site is supported by display advertising rather than subscriptions or paywalls.
- Is this financial or legal advice?
- No. ClearHome.ie's calculators are for general guidance only and don't constitute financial, tax, or legal advice. Always confirm figures that affect a real transaction with Revenue, the RTB, your lender, or a qualified professional.
- How accurate are the figures used?
- Every calculator states its sources and the date it was last reviewed, directly below the result. Rates and rules (like stamp duty bands or rent control caps) are sourced from Revenue, the RTB, and other official Irish sources, and are updated when the underlying rules change — not estimated.
- Which calculator should I start with?
- If you're buying, start with the Total Cost of Buying calculator to see the upfront cash you'll need, or Rent vs Buy if you're still deciding whether to buy at all. If you're renting, the Rent Tax Credit calculator and Notice Period calculator cover the two questions renters ask most.
