Useful next calculations
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 worked example
These are the example figures the calculator opens with.
| Input | Value |
|---|---|
| Sale Proceeds (€) | €200,000 |
| Original Cost (€) | €120,000 |
| Improvement Costs (€) | €0 |
| Selling/Legal Costs (€) | €0 |
For those figures the calculator returns:
- Capital gain: €80,000.00
- Taxable gain (after exemption): €78,730.00
- CGT payable (33%): €25,980.90
- Net proceeds after tax: €174,019.10
- Effective rate: 32.50%
- Gain on cost: 66.70%
How to read your results
Taxable Gain (after exemption)
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.
Net Proceeds After Tax
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.
Effective Rate
The effective rate lets you compare options on a like-for-like basis rather than being misled by different compounding periods or fee structures.
Method & assumptions
This calculator applies current Irish Revenue rules for Capital Gains Tax. The net gain is calculated by deducting the original acquisition cost, any allowable improvement expenditure, and selling/legal costs from the sale proceeds. The annual personal exemption of €1,270 is then subtracted from the net gain, and the balance — the taxable gain — is charged at the flat 33% CGT rate. No indexation relief is applied, as this was abolished for disposals made on or after 1 January 2003. The effective rate shown is the CGT payable expressed as a percentage of the total gross gain, giving a useful summary figure for comparison purposes.
This tool is designed for straightforward arm's-length disposals of a single asset. It does not cover Principal Private Residence relief, Retirement Relief, Entrepreneur Relief, CGT on gifts or inheritances, or situations involving part-disposals and development land. Gains on certain foreign assets may also be subject to different treatment. Always consult a qualified Irish tax adviser or Revenue's published guidance before filing, particularly where reliefs may significantly reduce or eliminate your liability.
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.
