What Geo Arbitrage Calculates
The exact month a move pays back its one-time costs through monthly surplus gains.
Geo Arbitrage answers one question: how many months past the move does the math go positive?
Moving is a one-time cost that pays back in monthly surplus gains — or doesn't. Geo Arbitrage takes four numbers (income here, cost here, income there, cost there) plus one-time move cost, and returns the break-even month. Under 6 months is fast payback; over 18 months requires commitment to stay.
Quick answer
Geo Arbitrage answers one question: how many months past the move does the math go positive?
Key points
- ▸ Formula: Monthly Gain = (Income − Cost)·Destination − (Income − Cost)·Origin. Break-even = Move Cost ÷ Monthly Gain.
- ▸ Monthly Gain can be negative — the move may cost more to live at than it saves in income. Negative gain = no break-even, move is pure preference.
- ▸ Under 6 months = fast payback, 6–18 months = reasonable, 18+ months = only if you commit to staying past break-even.
- ▸ Move cost includes everything: security deposit, movers, flights, broken leases, car shipping, temporary housing, visa fees, tax filings.
- ▸ Cost-of-living should be all-in: rent, taxes (state/local), groceries, transit, healthcare premium differential.
- ▸ Remote work variant: keep income flat, drop destination cost, move cost to relocation. The most common geo-arbitrage case today.
Examples
- $6,000/$4,500 here, $5,500/$2,800 there, $6,000 moveGain here $1,500. Gain there $2,700. Monthly gain $1,200. Break-even 5 months — fast payback.
- $7,000/$5,000 here, $7,000/$3,500 there (remote), $8,000 moveIncome unchanged. Gain here $2,000, gain there $3,500. Monthly gain $1,500. Break-even 5.3 months.
- $8,000/$5,500 here, $6,500/$4,500 there, $5,000 moveGain here $2,500. Gain there $2,000. Monthly gain −$500. No break-even — the move costs forever.
When to use which tool
- CYAN · STABLE — Break-even under 6 months — fast payback, move pays for itself within half a year.
- GOLD · GUARDED — Break-even 6-18 months — reasonable, only viable if you commit to staying past it.
- MAGENTA · CRITICAL — Break-even above 18 months or negative gain — skip, the move bets against itself.

Frequently asked questions
› What about taxes across states or countries?
Fold them into cost-there. Tax differential is often the biggest line item — use effective rate, not marginal. International moves need currency considerations and exit-tax treatment.
› Does it work for retirement relocations?
Yes — income is usually fixed (pension, Social Security, withdrawals). Compare cost-here vs cost-there at same income level. Move cost is one-time; break-even is typically fast because retirees plan to stay.
› What about intangibles — weather, family, schools?
The tool prices the financial floor. Intangibles live above that floor. A 12-month break-even with your family nearby is very different from a 6-month break-even 2,000 miles away.
› How should I use a decision framework in real life? How-to
Use a decision framework to expose the tradeoff, not to outsource the decision. Write down the inputs, compare the output with your constraints, then ask what would change the answer. The strongest use is scenario testing: base case, conservative case, and failure case.
› Is this financial, legal, or tax advice? Trust & accuracy
No, this is not legal, financial, tax, medical, or professional advice unless the page explicitly says that use case is supported. It organizes assumptions so you can inspect them. Verify high-stakes choices with qualified people who can review facts, contracts, regulations, and downside risk.
