How do I calculate my net paycheck?

Divide your annual salary by your number of pay periods to get gross pay. Then subtract federal income tax, state income tax, FICA (7.65%) and any pre-tax deductions like 401k and health insurance. A $75,000 salary paid biweekly has a gross paycheck of $2,884 and nets approximately $2,087 after taxes in an average state.

Does 401k reduce my paycheck taxes?

Yes. Traditional 401k contributions are pre-tax meaning they reduce your taxable income before federal and state taxes are calculated. A $200 biweekly 401k contribution reduces your gross paycheck by $200 but only reduces take-home by $156 because you save $44 in taxes.

What is FICA tax on my paycheck?

FICA is 7.65% of gross wages — 6.2% for Social Security and 1.45% for Medicare. Social Security only applies to the first $184,500 of annual earnings. Medicare applies to all earnings. On a $2,884 gross paycheck FICA is approximately $221.

Quick Answer

A $75,000 annual salary paid biweekly gives a gross paycheck of $2,884 before deductions. After federal tax ($432), state tax ($144 in an average state) and FICA ($221) the net paycheck is approximately $2,087. Adding a $200 401k contribution reduces take-home to $1,931 but saves $44 in taxes because 401k is pre-tax.

A paycheck calculator shows your net pay — what actually hits your bank account — after all federal and state income taxes, FICA contributions and pre-tax benefit deductions. Unlike a simple salary calculator a paycheck calculator accounts for pay frequency, 401k contributions, health insurance premiums and other deductions that affect your taxable income.
