When your wealth is spread across currencies, exchange rate movements can shift your net worth by thousands — even if your account balances don't change. A 10% swing in EUR/USD could move your FIRE date by a year or more. Most financial tools ignore this entirely. This calculator makes FX risk visible so you can plan around it instead of being surprised by it.
If you've moved countries, you likely have savings in your home currency, a salary in your current country's currency, and perhaps investments denominated in USD. Each of these is exposed to different FX movements. Consolidating everything into one base currency for planning purposes — while understanding the FX sensitivity — is the first step toward a clear financial picture.
Nobody can predict where exchange rates will be in 5 years. But you can plan for scenarios. Use the FX sliders to model a range of outcomes: what if EUR strengthens 10%? What if it weakens? The goal isn't to guess right — it's to know your plan survives the range of plausible outcomes.
Net Worth (EUR) = Σ (Account_i × FX Rate_i)FI Number = (Monthly Expenses × 12) / Withdrawal Rate
This calculator converts all your multi-currency accounts into EUR using adjustable exchange rates, then projects your net worth forward using compound growth on monthly savings. The FX sliders let you shift each currency pair by up to ±30% from the current mid-market rate, showing the impact on both your current net worth and your projected financial independence timeline.
An expat with €25,000 in EUR, $15,000 in USD, and £8,000 in GBP has roughly €47,000 in total wealth at current rates. With €2,000/month savings at 6% return, they reach financial independence (€1.2M at 4% withdrawal rate) in about 19 years. If EUR strengthens 10% against USD and GBP, their starting wealth drops to ~€44,500 — potentially adding a year to their timeline.
Start by entering your actual account balances in each currency. Be precise — even small accounts affect your total picture when FX moves.
Use the 'Strong EUR' and 'Weak EUR' presets to quickly see how a general currency shift affects your plan. Then fine-tune individual pairs.
If your FIRE timeline is sensitive to FX (more than 2 years difference between scenarios), consider gradually consolidating savings into your target retirement currency.
Your monthly savings rate matters more than FX movements over long time horizons. Focus on increasing savings before optimising currency allocation.
Review this forecast whenever you're considering a relocation — the combination of salary change and currency exposure can dramatically shift your trajectory.
