Inbound-worker tax regime: London. The 4-year FIG regime that replaced non-dom status relieves foreign income and gains, and it never touches a UK-earned salary. Overseas Workday Relief covers only duties performed outside the UK, capped at the lower of 30% of pay or GBP 300,000. Neither changes the take-home here.

Moving from San Francisco to London for a software engineer

$225,000 in San Francisco requires £173,271 in London to match on household net cash. The gap is real, but it is smaller than the nominal numbers suggest once taxes run their course. Progressive brackets compress the after-tax difference faster than a compensation benchmarking site would lead you to believe, because those sites show gross and stop there.

The effective tax rate goes from 30.6% in San Francisco to 35.5% in London. That 4.8-point jump is what the equivalence solver is working against when it finds the matching gross salary.

Unvested equity changes this calculation entirely. RSU value is not modeled in the defaults above, but if you are mid-cycle at your current employer, leaving means forfeiting grants you have already been working toward, and that difference can be larger than the annual take-home delta that drove the comparison in the first place. The Advanced section's "RSU / stock annual value" field is where you plug that number in. Equity-heavy comp favors lower-tax cities at vesting; the after-tax discount gets larger the bigger the grant.

On an employer plan the healthy years feel nearly free; it's the bad year that finds the gap. London is universal, so most of that tail risk goes away. San Francisco still runs $4,220 a year in premiums and out-of-pocket costs, and none of it shows up on an offer letter.

London engineers get 25 vacation days per year. San Francisco averages 0. That 25-day gap is real money at a senior IC's daily rate, and it does not show up on the offer letter.

No kids, employer healthcare, and a single high-bracket income: this is the configuration that makes San Francisco look best in a head-to-head comparison. It is also the configuration most likely to change. The family scenario page (linked below) models what shifts once childcare and a second earner enter the picture.

Common questions

How much do you need to earn in London to match a $225,000 salary in San Francisco?

About £173,271. cityparity solves for the London gross salary whose net cash (after taxes, housing, childcare, healthcare, and the rest) equals what you keep in San Francisco. It's an equivalence, not a raw conversion.

Is healthcare free in London?

London has universal healthcare, so there are no US-style premiums or large deductibles. cityparity counts that as real money you don't spend, which is part of why the equivalent salary is lower than the raw number suggests.

How much vacation and parental leave do you get in London?

London has about 33 paid days off a year (vacation plus public holidays) and 41 weeks of parental leave. cityparity surfaces these as deltas rather than dollars, because time off is part of the real comparison.
