What you actually take home

On $43,680 gross, a single filer pays roughly $3,062 in federal income tax and $3,342 in Social Security and Medicare, leaving about $37,277 — an effective rate of 14.7%. That is before any state income tax: in a no-income-tax state it is the whole story, but elsewhere expect another 2–6% off. The paycheck calculator by state shows the figure for where you live, and the main calculator lets you add a 401(k) and other pre-tax deductions.

Unpaid time off

The $43,680 figure assumes you are paid for all 52 weeks. Take two weeks unpaid and it drops to $42,000; the hourly rate is unchanged, there are just fewer paid hours in the year.
