Enter your current net worth, monthly savings, expected return, and annual expenses to find your financial-independence date — and whether you are already Coast FI against Irish state pension age 66.
An Ireland-localised calculator pre-filled in EUR. Use it to model growth inside a PRSA, employer pension, or EIIS-eligible investment over typical Irish working-life horizons.
FIRE rests on one formula: FI target = annual expenses ÷ safe withdrawal rate. At 4% SWR that is 25× your expenses. Once your portfolio reaches that number it can sustain inflation-adjusted withdrawals indefinitely (based on historical data).
In an Irish context: inside a PRSA or occupational pension, growth is tax-deferred and contributions attract income-tax relief up to age-banded limits (20–40% of income). Outside a pension, Ireland's deemed disposal rule taxes unrealised ETF gains at 41% every 8 years — a significant friction that makes pension wrappers very attractive. Model with a noticeably lower return rate (roughly 4–5%) for a brokerage account holding ETFs.
The Irish state pension age is currently 66. If your projected FIRE date is before 66, plan to self-fund the gap entirely — but if you are already Coast FI (shown above if applicable), your current portfolio can grow to the target without further contributions.
Worked example: A €10,000 PRSA balance plus €500/month at 7% for 25 years grows to about €415,000 — but remember that Irish exit tax on non-pension fund growth (currently 41%) can take a significant portion if held outside a pension.
FIRE stands for Financial Independence, Retire Early. The target portfolio is typically 25× your annual expenses (4% SWR). In Ireland, FIRE seekers typically hold assets in a PRSA or occupational pension, mindful of the deemed-disposal rule that taxes unrealised ETF gains every 8 years outside a pension.
The SWR is the annual percentage you can withdraw without running out of money. The Trinity Study found 4% survived 95% of 30-year historical scenarios. For Irish early retirees with 40+ year horizons, 3–3.5% provides additional margin.
For a globally-diversified equity index fund inside a PRSA, 6–8% nominal is a common historical assumption. Outside a pension, Ireland's deemed disposal rule taxes unrealised ETF gains at 41% every 8 years — model with roughly 4–5% effective return for a brokerage account.
Coast FIRE: your portfolio can grow to FI by Irish state pension age (66) without further contributions. Lean FIRE: under roughly €20,000/year. Fat FIRE: €60,000+/year. Change the annual expenses input to model each scenario.
Inside a PRSA, growth is tax-deferred and contributions get income-tax relief up to age-banded limits. The first €200,000 pension lump sum is tax-free. Outside a pension, Ireland's deemed disposal rule means ETFs are taxed at 41% every 8 years on unrealised gains. The state contributory pension is payable at age 66.
