Moving from Boston to Porto for a family
For a family of four, this comparison produces a different answer than a single-person look at the same cities. Childcare costs, parental leave policy, and the second earner's tax treatment all push the number. With a partner at 60% of the primary salary and two kids in daycare, a $280,000 household in Boston needs €228,064 in Porto to keep the same net cash.
Childcare is the biggest single swing factor in this comparison. Boston households pay $33,600 per year; Porto caps it at €360 via subsidy. That difference flows directly to net cash. A standard salary comparison won't show it at all.
Parental leave is similar: 10 weeks paid in Boston, 17 in Porto.
With kids in the house, healthcare is the line that quietly compounds. Porto runs a universal system, so a rough year doesn't turn into a billing event. The Boston side carries $10,916 a year in premiums and out-of-pocket costs, exposure that simply doesn't follow you across.
K-12 schools score higher on PISA 2022 in USA (489 (math 465, reading 504, science 499)) than in Portugal (478 (math 472, reading 477, science 484)), a 11-point gap on the OECD's standardized 15-year-old assessment. PISA is one signal; local school choice and curriculum philosophy matter at least as much.
Porto also adds 7 more vacation days per year (22 vs 15). With kids, that is school breaks actually covered without burning PTO.
The second-earner question is worth running separately. In high-childcare-cost cities, full-time daycare can eat most of a partner's after-tax income. In Porto, subsidized childcare changes that math entirely: both salaries actually make it to the household. Use the "Partner works in" toggle in the calculator to see what that shift does to your specific numbers.

Is healthcare free in Porto?
