About the FICA Tax Calculator
FICA (Federal Insurance Contributions Act) tax funds Social Security and Medicare and is withheld automatically from most US paychecks at fixed percentage rates.
Formula: Social Security Tax = Gross Wages × 6.2% · Medicare Tax = Gross Wages × 1.45% · Total FICA = Social Security + Medicare
This calculator uses the standard employee rates and does not apply the annual Social Security wage base cap or the additional Medicare surtax on very high earners.
