Every figure above is gross pay — what you earn before anything comes out.
Search for "$16 after taxes" and you will find sites that hand you one confident number.
Treat those carefully, because the honest answer depends on things only you know.
Four separate deductions decide what actually reaches your account:
Income tax, charged in bands. This is the part most people get wrong: moving
into a higher band does not tax all of your income at that rate, only the slice above the
threshold. Your effective rate is always lower than your top band.
Social security or national insurance — usually a flat percentage,
sometimes capped once you pass a certain income.
Where you live. Two people both earning $16 take home noticeably different
amounts if one lives somewhere with a regional or state income tax and the other does not.
What you have opted into — pension or retirement contributions, health
cover and similar. These come out before you ever see the money, and they differ per person
even inside the same company.
Because of the last two especially, a single "after tax" figure for $16 would be wrong for most
of the people reading it. Your most recent payslip is the only accurate source, and it already
has the number on it.
