Why most FIRE calculators get this wrong
The classic 4% rule assumes you spend in the same currency your portfolio grows in. For nomads, that's rarely true: a EUR-denominated Vanguard fund finances a lifestyle priced in Czech korunas, Thai baht, or Polish złoty.
When the EUR strengthens against CZK (as it did in 2022), your FIRE number drops because your purchasing power improves. When EUR weakens (2023–2024 corrections), the same portfolio funds fewer korunas. This volatility can swing your required portfolio by 10–25% depending on the currency pair.
This tool uses representative 5-year historical ranges and annualised volatility estimates to show the realistic FIRE number band, not just the mid-rate snapshot.

Frequently Asked Questions
What is currency risk in FIRE planning?
Currency risk is the chance that exchange rate moves will change your effective purchasing power. If your portfolio is in EUR but you spend in SEK, a weaker EUR means you need more euros to fund the same lifestyle.
How are the FX rates calculated?
Rates and volatility figures are hard-coded representative values based on approximate 5-year historical data (2019–2024). They are not live and should be treated as order-of-magnitude estimates only.
What is the volatility band?
The band shows your FIRE number adjusted by ±1 standard deviation of annual FX moves. A 10% annual vol means your number could be 10% lower or higher than the central estimate in any given year.
What does the 4% rule mean here?
We use the classic 25× annual spending rule (4% safe withdrawal rate) as the baseline. Currency adjustments are applied on top: they affect the required portfolio size, not the withdrawal rate itself.
