When to use this calculator
- Before accepting a pay change, bonus or contribution arrangement.
- When you want a simple take-home or conversion estimate before payroll or filing.
- When you need to convert between hourly, monthly and annual pay.
- When you want to compare two pay scenarios using the same assumptions.
A realistic Ireland planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
| Input | Value |
|---|---|
| New Property Purchase Price (€) | €350,000 |
| Total Income Tax & DIRT Paid — Last 4 Years (€) | €45,000 |
| Your Deposit (excl. HTB) (€) | €70,000 |
| Mortgage Amount (€) | €280,000 |
After entering these figures, review htb rebate, total effective deposit and deposit as % of price together rather than in isolation. Then rerun the tool with one input adjusted.
How to read your results
HTB Rebate
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Total Effective Deposit
The headline outcome of this calculation. It is most useful when read alongside the supporting metrics rather than in isolation.
Deposit as % of Price
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Mortgage LTV
This ratio compares the loan with the asset value you entered. It is only meaningful when both figures belong to the same deal.
Maximum You Could Claim
The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.
Method & assumptionsAuthoritative sources
This calculator applies the 2024 Help to Buy (HTB) scheme rules as administered by Revenue Ireland. The rebate is calculated as 10% of the purchase price, subject to a hard cap of €30,000 and further limited to the total income tax and DIRT paid by all applicants in the four tax years immediately prior to the application year. Both eligibility tests — property price at or below €500,000, and a mortgage-to-price ratio of at least 70% — must be satisfied for any rebate to be issued; if either condition is not met, the result shown will be zero. The effective deposit figure combines your personal deposit with the estimated HTB rebate, and the deposit percentage shows how this total stands against the purchase price. These are estimates only: the actual rebate amount is determined by Revenue based on verified tax records submitted through myAccount or ROS, and may differ if your tax history includes years of self-employment, partial-year employment, or foreign income.
For self-build applicants, the 70% LTV test is applied against the approved valuation of the completed property rather than the site cost alone, which can affect eligibility calculations significantly. The HTB scheme has been extended to 31 December 2025 under Budget 2024, but the rules, caps, and thresholds are subject to annual review. Always check the current scheme terms on Revenue.ie before proceeding, and consider taking independent mortgage or financial advice to understand how HTB interacts with your full mortgage application, including your lender’s own minimum deposit requirements and stress-test criteria.
Common mistakes
- !Using an assumption that is not supported by a current local quote, bill, statement or official source.
- !Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- !Mixing monthly and annual inputs without converting them consistently.
- !Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
