Formula & method
Payroll Tax & Take-Home Equations
Gross Paycheck = Annual Salary ÷ Pay Frequency · Taxable Pay = Gross − Pre-tax Deductions · FICA = Gross × 7.65% · Net Pay = Gross − FICA − Income Taxes − Pre-tax Deductions
Pre-tax deductions include 401(k) and health insurance. Income taxes apply to Taxable Pay.
Example
$75,000 salary paid biweekly (26 pay periods, $2,884.62 gross) with 6% 401k ($173.08), $69.23 health, $220.67 FICA, and 19% tax ($496.22) → Net Paycheck: $1,925.42 (66.7% take-home).
Key insights
Pre-tax deductions (like 401k contributions and HSA/health insurance premiums) reduce your taxable gross income dollar-for-dollar.
FICA taxes (Social Security 6.2% and Medicare 1.45%) total 7.65% on gross wages up to the annual Social Security wage base limit.
Biweekly pay schedules result in 26 paychecks per year, meaning two months each year will contain 3 paychecks ('bonus pay periods').
Increasing your 401(k) contribution by 1% reduces your net take-home pay by LESS than 1% because of tax savings.
