FIRE Calculator 2026

What is a FIRE number?

Finnish capital gains tax (pääomatulovero) is 30% on annual gains up to €30,000 and 34% above that. This differs significantly from the US-centric 4% rule which ignores taxes. The calculator computes your FIRE number including Finnish capital gains tax, giving a more realistic result than a simple 25× annual expenses.

Hankintameno-olettama (acquisition cost assumption) means that for investments held over 10 years, 40% of the sale proceeds are tax-free. Only 60% of each withdrawal counts as taxable capital gain. For example, withdrawing €50,000/year means only €30,000 is taxable — at 30% that's €9,000 tax, not €15,000. The calculator applies this 40% assumption to all withdrawals.

Finnish pension (työeläke) and your FIRE number are linked: state pension payments begin at age 65 and reduce how much you need to withdraw from your portfolio. This is why the "with pension" curve flattens at age 65 in the chart. You can look up your estimated pension at Tyoelake.fi.

Real return means return after inflation. Enter your return net of inflation: for example, 7% nominal return minus 2–3% inflation = 4–5% real return. A conservative estimate is 4–5%.
