Take-home pay is your gross salary minus federal income tax, state income tax, Social Security (6.2% up to the wage base), and Medicare (1.45%, plus 0.9% on income above $200,000 for single filers). Pre-tax deductions like 401(k) contributions and health insurance reduce the taxable portion further.

Your marginal tax rate is the rate on your last dollar earned — the top bracket your income reaches. Your effective rate is total tax divided by gross income, which is always lower than your marginal rate because earlier dollars are taxed at lower brackets.
