Geo-Arbitrage Velocity Calculator
Your ZIP code might be the most expensive thing you own. Compare tax and cost-of-living between here and there, and see how many years a move could shave off your path to freedom.
Under the hood
The math, fully exposed
We compute savings in both locations, then how long each takes to reach financial independence (4% rule):
Net income = gross × (1 − tax rate)
Target spending = current spending × cost-of-living index
Annual savings = net income − spending (per location)
FI number = annual spending × 25
Years to FI = ln(1 + FI × return ÷ savings) ÷ ln(1 + return)
Years saved = FI years now − FI years after the move
- Two compounding levers: a lower tax rate raises savings, and a lower cost of living both raises savings and lowers the FI number you\'re aiming at — a double effect on the timeline.
- 4% rule basis: we target 25× the location\'s annual spending. Adjust your spending and cost-of-living sliders to model the exact lifestyle you\'d keep.
- Simplified, and tax is hard: real cross-border taxation (worldwide income, exclusions, treaties) is complex. This sizes the prize; a professional confirms the number.

Answers
Frequently asked questions
What is geographic arbitrage?
Geo-arbitrage is earning in a strong currency or market while living somewhere with lower taxes and a lower cost of living — keeping the income, shedding the expenses. For remote workers and location-independent founders, moving from a high-tax, high-cost city to a cheaper, lower-tax one can dramatically raise the savings rate and pull financial independence years closer.
How much can relocating actually save?
Two levers stack: the tax difference (keeping more of each dollar earned) and the cost-of-living difference (spending fewer dollars to live the same life). A move from a 30%+ tax, high-cost metro to a low-tax, lower-cost location can easily double or triple the annual amount you invest — which compounds into years off your timeline.
What about taxes if I move abroad?
This is where it gets serious. US citizens are taxed on worldwide income regardless of where they live, though tools like the Foreign Earned Income Exclusion and foreign tax credits can reduce it; other countries tax by residency. Schemes like territorial taxation, non-dom status or special expat regimes vary enormously. The model here is a simplified estimate — get qualified cross-border tax advice before acting.
What are the hidden costs of geo-arbitrage?
The money math is only part of it. Visas and residency, international health insurance, distance from family and community, schooling, currency risk, time zones for work, and the one-time cost and stress of moving all matter. The "net net" gain is real, but weigh the financial velocity against the life you'd be trading.
