How to use it
- Enter your FIRE target spending, destination country, expected healthcare costs abroad, local tax obligations, and any home-country tax liabilities you cannot escape. Use real cost-of-living data for the destination, not tourist-budget estimates.
- Read the adjusted FIRE number and compare it against a domestic FIRE target. The gap between the two reveals how much geographic arbitrage actually buys you after healthcare and tax adjustments are included.
- If the adjusted number is less than 60% of a domestic target, the destination likely offers real acceleration. If healthcare or tax costs eat most of the savings, the move is a lifestyle choice more than a financial shortcut.
- Model two or three destination countries side by side, then stress-test with a weaker exchange rate and higher healthcare inflation. Pair with the geographic arbitrage calculator for a salary-versus-cost view.
- Re-run when exchange rates move by 10%+, healthcare policy changes in either country, or your spending assumptions shift. Track adjusted FIRE number, healthcare share of spending, and net tax burden.

Agent playbook

- Open the browser page only when a person wants to review charts, assumptions, or related tools.
Agent FAQ
Should ChatGPT, Claude, or another agent click through the UI?
No. Start with /agent-tools.json, then follow the tool's contract URL. The page UI is for human review, not parameter discovery.
When do tools show Quick and Advanced?
Every tool opens in Quick Start first. Advanced Controls keeps the same scenario, reveals more assumptions or diagnostics, and every tool keeps AI integrations inline below the instructions.
When should an agent still open the browser page?
Open it when a human wants to sense-check the output, review the chart, or keep exploring related tools after the calculation finishes.
Questions people usually ask
How does this differ from a standard FIRE calculator?
It adjusts your FIRE number for your destination country's cost of living, healthcare costs, visa fees, and local tax obligations. A $1.2M FIRE target in the US might translate to $600K for Portugal or $450K for Thailand once these factors are modeled.
How accurate are the cost-of-living adjustments?
The tool uses broad cost-of-living indices as a starting baseline. Actual costs vary by city, lifestyle, and currency fluctuation. Treat the output as a planning range, not a guarantee, and validate with on-the-ground research.
Do I still owe US taxes if I move abroad?
US citizens and green card holders owe federal income tax on worldwide income regardless of where they live. The Foreign Earned Income Exclusion (FEIE) and Foreign Tax Credit can offset some liability, but investment withdrawals are generally still taxed by the US.
When should I use this instead of the standard FIRE calculator?
Use this when you plan to retire or semi-retire outside your home country. If you are staying domestic, the standard FIRE calculator is simpler and more appropriate. This tool adds value specifically when geographic arbitrage is part of your plan.
Is my data stored?
No. All calculations happen in your browser. Nothing is stored or transmitted.
Can I model multiple destination countries side by side?
Run the calculator once per country and compare the outputs. Each destination has different cost-of-living ratios, healthcare models, and tax treaties, so the FIRE number can vary dramatically between options.
