Is It Common to Underestimate Costs When Planning to Retire Abroad?

By The Penny Plan Editorial Team Published July 13, 2026 5 min read

A cost-of-living comparison shows a country where rent, groceries, and everyday expenses cost a fraction of what they do at home, and retiring there starts to look like it stretches savings much further. That comparison is real, but it’s usually only part of the picture, and the gaps tend to show up after the move rather than before it.

In short

Yes, it’s common for early cost estimates to miss real expenses. Widely cited cost-of-living figures typically reflect averages for local residents and everyday categories like groceries and transportation, but they often leave out costs that specifically affect newcomers and retirees, including healthcare access, visa or residency fees, currency conversion costs, and periodic trips home. Those gaps can meaningfully change the math compared to the headline number.

Costs that don’t show up in general comparisons

Why the gap tends to widen over time

Cost estimates made before a move are often based on research done from a distance, using published averages or other expats’ informal accounts. Once someone is actually living somewhere, costs specific to their situation — a particular neighborhood, a particular health condition, a particular family circumstance — start to matter more than the general average ever could. This is part of why some retirees find that early confidence about affordability gives way to a more cautious recalculation after the first year or two, especially if they’re also navigating normal anxiety about market conditions affecting the funds they’re drawing from.

Building in a margin for the unknowns

Because so many of these costs are hard to estimate precisely from home, a wider buffer than the headline cost-of-living figure suggests is generally a reasonable planning approach. That might mean researching healthcare options specific to the intended country in detail, getting a clear picture of visa renewal costs over multiple years rather than just the first one, and understanding how income drawn from retirement accounts is taxed both at home and abroad. For those who haven’t finished building retirement savings before considering a move like this, the underestimated costs matter even more, since there’s less room to absorb a surprise.

What to weigh

Advertised cost-of-living numbers describe an average, not a specific retiree’s full situation. Costs tied to healthcare, legal status, currency, and staying connected to family back home are the ones that most often get left out of the early math, and they’re worth researching in detail well before any decision is finalized.
