Most people planning a move abroad ask the wrong first question. They ask “how much does it cost to live in [country]?” when the number that actually determines whether the move works is runway — how many months you can survive with zero income if things don’t go according to plan.
Visa delays happen. Freelance income dries up for a month. A remote job disappears. Runway is what keeps a rough patch from turning into a plane ticket home.
What Runway Actually Means
Runway isn’t your total savings. It’s a specific calculation:
- Liquid savings available for the move, minus
- One-time setup costs (visa fees, flights, shipping, security deposits, apostilles and certified translations), divided by
- Your estimated monthly cost of living at the destination
The number that’s left is your runway in months. Under 3 months is high-risk — one delayed visa approval or one slow month of freelance income can force a premature return. 6+ months gives real room to adjust, find income, or fix a surprise without panicking.
Why This Number Gets Skipped
Destination content — blog posts, YouTube channels, “best places to live” roundups — almost never talks about runway, because it’s not aspirational. It’s the boring math that happens before the exciting part. But skipping it is the single biggest reason first-time moves fail: people move with enough money to get there, not enough to stay through the inevitable rough first few months.
A Quick Example
Say you have $18,000 in liquid savings and you’re eyeing a move to Portugal.
- Visa fees, flights, shipping, and deposits: roughly $4,000
- Savings remaining after setup: $14,000
- Estimated monthly cost of living in a mid-size Portuguese city: $1,800
$14,000 ÷ $1,800 ≈ 7.7 months of runway.
That’s a solid position — enough time to find local income, absorb a slow month, or handle a surprise expense without your visa status or your bank account collapsing at the same time.
Now compare that to someone moving with the same $18,000 but choosing a destination where monthly costs run $3,000. Their runway drops to under 5 months. Same savings, same move — very different margin for error.
The Line-Items People Forget to Budget
Beyond flights and shipping, the setup costs that quietly eat into runway before you’ve even landed:
- Visa application and processing fees
- Apostilles and certified document translations
- Temporary housing while you search for a permanent place
- Currency conversion costs and international transfer fees
- International health insurance (often required for visa approval, not optional)
- A genuine emergency cushion — not folded into “living expenses”
All-in, these setup costs commonly run $5,000–$15,000 before day-to-day life even starts. Guides that only budget flights and a security deposit are setting people up to underestimate by thousands.
How to Actually Calculate Yours
- Total your liquid savings earmarked for the move.
- Subtract realistic one-time setup costs for your specific destination (research actual visa fees, don’t guess).
- Divide what’s left by a realistic monthly cost-of-living estimate — not the optimistic number from a “cheap countries to retire” listicle, the number that includes health insurance, a real housing budget, and normal life.
- That’s your runway in months. Be honest with yourself about whether it’s enough for your risk tolerance.
If you want a structured way to work through this instead of doing it on the back of an envelope, the free Move Abroad Readiness Audit walks through 27 questions covering exactly this — finances, timeline, and Plan B — and tells you in about 10 minutes whether you’re planning-ready or move-ready.
The Bottom Line
The question isn’t “can I afford to live there?” It’s “can I afford to live there and survive the unexpected?” Runway is the number that answers that. Calculate it honestly before you book anything.
