## Tools (1)

- `take_home_pay`: Net salary after income tax and social contributions for an employee in one of ten countries (uk, us, ca, au, in, br, pl, fr, de, es), computed live by the LifeByNumbers salary calculators (same operator). Takes a gross salary in local currency (annual by default, or monthly with period) and a country code, plus optional state and filingStatus for the US, province for Canada, region (england|scotland) for the UK. Returns gross, net and total deductions (each annual and monthly), a line-by-line breakdown typed as tax / social / contribution / repayment, effectiveRate, the tax year the figures apply to, currency, the assumptions behind the estimate and the upstream calculator page as source. Spain (es) is listed but answers covered:false because lifebynumbers.net computes it client-side only.
