Moving from Seattle to London
$150,000 in Seattle is worth £139,105 in London on a household net-cash basis. That is the equivalence figure this tool solves for: the London gross salary whose take-home, after taxes and local costs, lands in the same place as your Seattle take-home. Most people are surprised by how large the number is. Most of the gap is taxes.
The effective tax rate goes from 24.1% in Seattle to 35.8% in London. That 11.7-point jump is what the equivalence solver is working against when it finds the matching gross salary.
Healthcare in London is universal. Seattle households pay $4,490 in premiums and out-of-pocket costs per year, and that spending disappears in London. It won't show up in a take-home comparison, but it's real money.
London workers get 20 vacation days per year. Seattle averages 0. That 20-day gap does not appear in any salary comparison, but at a typical professional's daily rate it represents thousands of dollars of time that stays in your life rather than being bought back by your employer.
Living costs (housing, food, transit, discretionary) total $52,037 in Seattle and £46,542 in London at these scenario defaults. The breakdown table shows each line item separately, with source citations and last-updated dates available on hover.
