Geographic arbitrage means earning money (or holding investments) priced in an expensive economy while spending it somewhere cheaper. It works for FIRE because your target is roughly 25 times your annual spending: every $1,000 a year you stop spending removes about $25,000 from the number you need. Cut spending from $100,000 to $60,000 by moving and your target falls from $2.5 million to $1.5 million.
If you’re still working remotely, the effect doubles, because the money you stop spending becomes money you save. That’s why a move can take a decade or more off a FIRE timeline in a way coupon-clipping never will.
How much can geographic arbitrage cut your FIRE number? #
Start with the target itself. At a 4% withdrawal rate:
| Annual spending | FIRE number (x25) |
|---|---|
| $100,000 | $2,500,000 |
| $80,000 | $2,000,000 |
| $60,000 | $1,500,000 |
| $50,000 | $1,250,000 |
Now the timeline. Take a household with $140,000 of after-tax income, starting from zero and earning 5% a year after inflation.
- Before the move: spends $100,000, saves $40,000, needs $2.5 million. About 29 years.
- Moves but keeps the same income: spends $60,000, saves $80,000, needs $1.5 million. About 13.5 years.
Same job, same salary, roughly half the working years. The effect is smaller if your pay drops after the move, which is common when employers adjust salaries by location, so run the numbers with the pay you’d actually get.
To test your own version, Retire Goals has a FIRE Number calculator (spending divided by your withdrawal rate) and a compound growth calculator that shows how long a monthly contribution takes to reach a target. Plug in your current and post-move numbers and you have both timelines in a minute. Our guide on how to calculate your FIRE number covers choosing the withdrawal rate.
Domestic vs international geographic arbitrage #
Moving within the U.S. #
You don’t need a passport to benefit. Moving from a high-cost metro to a mid-sized city in a cheaper state can cut housing, insurance and state income tax at once.
- Housing: selling an appreciated home in an expensive area and buying for less elsewhere can free up hundreds of thousands of dollars to invest.
- State income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas and Wyoming have no broad state income tax, and New Hampshire and Washington don’t tax wages. Washington does tax large long-term capital gains, which matters to retirees selling investments. Retirees should also compare property taxes and how each state treats IRA withdrawals and pensions.
- Health care and services: costs vary a lot by region, so check premiums in the new ZIP code, not national averages.
Moving abroad #
Popular choices for early retirees include Portugal, Spain, Mexico, Costa Rica, Thailand and Colombia. Everyday costs in many of these places run well below a U.S. metro, and private health insurance can cost a fraction of U.S. premiums. Check a specific city on cost-of-living sites like Numbeo and in expat forums, not a country average, and add 15% to 20% for costs locals don’t have: flights home, international health cover, visa renewals.
Working vs retired #
- While working (active arbitrage): you keep a remote salary from an expensive market and pay local prices. This is where savings rates of 50% or more come from.
- After retiring (passive arbitrage): your portfolio stays the same but your spending drops, so your withdrawal rate falls. A 4.5% withdrawal in San Diego might be a much safer 3% somewhere cheaper.
What are the tax traps of geo-arbitrage? #
Taxes decide whether a move is as good as it looks.
- U.S. citizens are taxed on worldwide income wherever they live. The Foreign Earned Income Exclusion covers wages and self-employment income only, so it does nothing for IRA withdrawals, dividends or capital gains. Retirees rely more on the foreign tax credit and on tax treaties.
- Your new country may tax you too. Some tax foreign dividends, pensions or even Roth withdrawals that the U.S. treats as tax-free. Special regimes for new residents change often, so read the current rules or pay for one session with a cross-border tax adviser before you commit.
- Leaving a high-tax state takes proof. California and New York are known for auditing former residents. Change your driver’s license, voter registration, mailing address and primary bank, and keep records of where you spend your days.
How does health insurance work if you move? #
Inside the U.S., the ACA marketplace is state-based, so premiums and plan choices change when you move. The extra pandemic-era subsidies ended on December 31, 2025, per HealthCare.gov, so price a plan in your new area before assuming it’s cheap. Our guide to health insurance in early retirement walks through the options.
Abroad, Medicare generally doesn’t cover care outside the U.S., and ACA plans require U.S. residence. You’ll use the local public system if you’re eligible, local private insurance, or international expat coverage. Factor that into the move before you factor in the cheap rent.
The risks people underestimate #
- Currency swings. If your portfolio is in dollars and your rent is in euros or pesos, a weaker dollar raises your cost of living overnight.
- Distance from family. This is the most common reason moves get reversed. Video calls don’t replace being there for a parent’s surgery.
- Local inflation. Expat hot spots tend to get expensive as more remote workers arrive.
- The cost of undoing it. Moving back costs money too. Keep that cushion in your plan.
- Brokerage access. Some U.S. brokers restrict accounts for customers living abroad, and EU residents often can’t buy U.S.-domiciled funds because of EU disclosure rules. Check your broker’s policy before you go.
Step-by-step: test a move before you make it #
- Run the numbers. Current spending and savings versus realistic post-move spending, savings and pay.
- Slow-travel first. Live in the city for one to three months, ideally off-season. Rent an apartment, buy groceries, deal with an internet installer.
- Sort out legal residence. Many countries offer retirement or passive-income visas and remote-worker visas, but requirements (minimum income, health insurance, time in the country) differ and change. Use the country’s official consulate site.
- Set up money logistics. Low-fee ways to move money, a card without foreign transaction fees, and a plan for your mailing address.
- Give it six months before judging. The first months in a new place are rarely representative.
If you move abroad, Retire Goals shows amounts in your phone’s currency or one you choose in Settings. It doesn’t convert between currencies, so keep each goal in the currency you actually spend.
Frequently asked questions #
Is geographic arbitrage legal for remote employees? #
Yes, but your employer has to be on board. Working from another state or country can create tax, payroll and employment-law obligations for the company. Tell HR where you’ll be before you move, not after.
Can I get Social Security if I retire abroad? #
In most countries, yes. The Social Security Administration pays benefits to U.S. citizens living in most countries, with a short list of exceptions, and it offers an online tool to check a specific country. Medicare is a different story, since it generally won’t pay for care abroad.
How does geo-arbitrage affect Coast FIRE or Barista FIRE? #
It makes both easier. With lower living costs, a part-time job covers a bigger share of your spending, so the portfolio you need for Barista FIRE shrinks, and a coasting phase is cheaper to fund.
What happens to my U.S. brokerage account if I move abroad? #
Most people keep their accounts, but rules vary by broker and by country. Some firms limit trading or new purchases for non-residents, and a few close accounts. Ask your broker in writing before you move, and don’t rely on a relative’s U.S. address as a workaround without checking whether that’s allowed.
