Geographic arbitrage, moving to a cheaper place to make the same money go further, gets pitched online like a hack. It's not. It's a real strategy with real tradeoffs, and the spreadsheet version usually misses the parts that matter most.
The calculator below takes your current annual spending, your destination cost, your time horizon, and tells you what the move is actually worth, accounting for what you'd save and what that saving compounds to over time if you invest it.
Most online "cost of living comparison" sites give you a single number and a "you'd save 32%" headline. That number is almost always wrong in the direction of "too rosy." This one tries to be honest about the math, and it doesn't pretend the math is the whole decision.
Illustration only, not financial, tax, or relocation advice. Assumes your income is portable, that it does not fall when you move, and a constant 7% nominal return on anything you invest. The cost multiplier is a rough, editable starting point drawn from 2026 cost-of-living data, not a precise figure: real cost of living varies by household, neighborhood, and year far more than by region. Move the slider to match what you have actually researched. These figures capture only the financial gap; they deliberately do not price the personal, family, healthcare, legal, and tax tradeoffs in the list above, because no honest tool can. Excludes moving costs, buying or selling a home, currency risk, and double-taxation exposure.
Before the condo there was the RV. Two years, 48 states. I sat down to dinner with people in Wyoming who'd traded San Francisco salaries for a porch and never looked back, and with people in Florida who'd retired-arbitraged themselves into a town they couldn't stand. The math worked for both. Only one set was happy. That's the part the spreadsheet can't catch.
Then I bought a condo in Playa del Carmen in 2020 when the peso devalued. I've spent significant time in Mexico every year since. The cost-of-living math is real: a thoughtful, minimalist life there is roughly half the cost of the same life in the U.S. The savings are not a fantasy. But the math the spreadsheets don't show:
The first move is mostly upside. The second one is where you find out which of your friendships were real estate and which were friendships.
What the spreadsheet captures: rent, food, utilities, taxes, healthcare, transportation. Maybe insurance and currency exposure if it's a good one.
What it doesn't: the value of being twenty minutes from your aging parents. The cost of flights home for funerals you'll have to attend. The career-network attrition that happens slowly until one day you notice your inbox has stopped delivering opportunities. The tax complexity of a move you didn't plan well. The professional licensing reciprocity questions if your income depends on a license. The school-system disruption if you have kids. The medical-care quality difference if you have a chronic condition. The visa structure that may or may not let you stay as long as the spreadsheet assumes.
None of these kill the strategy. All of them affect the answer. The honest version of geographic arbitrage is: it works, often beautifully, for people who run the full math, not just the rent comparison.
Geographic arbitrage compounds best for: location-independent earners (remote employees, founders, freelancers), people in or near retirement with portable income, dual-income couples where at least one income is portable, and people whose biggest costs are HCOL-specific (childcare, real estate, state income tax). It works worst for: people whose income is geographically tied (W-2 in a specific industry cluster), people with strong existing community roots they're not willing to risk, and people whose family obligations require physical proximity.
For the people it works for, geographic arbitrage can shave 5 to 15 years off the path to financial independence. That's not a small number. It also isn't free.
A move abroad or across the country is a bet. Worst realistic case, can you survive it, upside, asymmetry: four questions before the deposit.
For people weighing a different place, pace or setup, the full map beyond the math.
It means moving somewhere cheaper so the same income goes further. It is a real strategy with real tradeoffs, not a hack. This calculator takes your current annual spending, the destination's cost relative to it, and how many years you would stay, then shows the yearly gap and what it compounds to if you invest it.
It can be, for people who run the full math and not only the rent comparison. The savings are real: the page notes a thoughtful, minimalist life in Mexico runs roughly half the U.S. cost. What the math leaves out: distance from aging parents, career network, schools, medical care, visas and tax complexity.
It tends to work for location-independent earners, people in or near retirement with portable income, dual-income couples with at least one portable income, and people whose biggest costs are tied to a high-cost area. It works worst when income is tied to a place, community roots run deep, or family needs you nearby.
That your income does not fall when you move, and that anything you invest earns a constant 7% nominal return. The cost slider is a rough starting point from 2026 cost-of-living data, meant to be adjusted to what you have actually researched. It excludes moving costs, home sales, currency risk and double taxation.

Who I work with: founders, business owners and families who want one fee-only advisor for the whole picture. Ongoing planning runs $150 to $500 a month; investment management is about 1% a year, lower as assets grow; no account minimum. Not ready for that? The Purpose Pit Stop is a half day for $750.
