What this does and does not include

This compares take-home pay only — income tax and compulsory social contributions, nothing else. It does not adjust for rent, childcare, healthcare or schooling, and those differences are often larger than the tax ones. A salary that looks better in London can still leave you worse off once housing is paid for.

The exchange rate is the European Central Bank reference rate for 2026-09-04. Rates move; the tax arithmetic does not.
