Bonus coming? It isn't really taxed at 40%
That shrunken bonus check is withholding, not your real tax rate — the flat 22% federal supplemental rate plus payroll taxes comes out up front, and the difference reconciles when you file. See exactly what will land in your account before it arrives.

Why these calculators?
Most pay questions come up at a stressful moment: you just got a raise offer, you're leaving a job and want your unused vacation paid out, or you're weighing two offers that structure compensation completely differently. PaycheckKit turns each of those moments into a two-minute answer with the formula shown, so you can double-check the math yourself.
