Payroll Tax Calculator
Calculates total employer-side payroll taxes — Social Security, Medicare, FUTA, and SUTA — based on gross wages and applicable rates. Use it to budget labor costs or verify payroll runs.
About this calculator
Employers are required to pay several taxes on top of employee gross wages. Social Security (6.2%) and Medicare (1.45%) together form FICA, which employers match dollar-for-dollar. FUTA (Federal Unemployment Tax Act) is a federal unemployment insurance contribution, typically 6% on the first $7,000 of wages but often reduced by state credits. SUTA (State Unemployment Tax Act) rates vary by state and employer experience rating. The formula is: totalTax = grossWages × (socialSecurityRate + medicareRate + futaRate + sutaRate) / 100. Note that Social Security and FUTA have annual wage-base caps, so actual tax liability decreases once an employee's earnings exceed those thresholds. This calculator gives an accurate estimate when used with the correct effective rates for your specific situation.
How to use
An employee earns $5,000 gross wages. Rates: Social Security 6.2%, Medicare 1.45%, FUTA 0.6% (after state credit), SUTA 2.7%. Sum the rates: 6.2 + 1.45 + 0.6 + 2.7 = 10.95%. Total employer tax: $5,000 × 10.95 / 100 = $547.50. Of that, $310 is Social Security, $72.50 is Medicare, $30 is FUTA, and $135 is SUTA. The total employment cost for this pay period is $5,000 + $547.50 = $5,547.50.
Frequently asked questions
What is the difference between FUTA and SUTA payroll taxes?
FUTA is a federal tax that funds the national unemployment insurance system, while SUTA is a state-level tax that funds unemployment benefits paid to workers in that state. FUTA is set at 6% on the first $7,000 of wages, but employers who pay SUTA on time can receive a credit of up to 5.4%, reducing the effective FUTA rate to 0.6%. SUTA rates vary widely by state and are influenced by the employer's claims history — a concept called experience rating. High turnover industries typically face higher SUTA rates.
How do Social Security wage base caps affect employer payroll tax calculations?
Social Security tax only applies to wages up to the annual wage base limit, which is $168,600 for 2024. Once an employee's cumulative earnings for the year exceed this cap, neither the employer nor the employee owes additional Social Security tax on those wages. This means high-earning employees become less expensive in employer tax terms later in the year. FUTA has a much lower cap of $7,000 per employee, so it is typically exhausted early in the year for most workers.
Why should small businesses calculate employer payroll taxes separately from gross wages?
Employer payroll taxes are a real labor cost that does not appear in the employee's paycheck, making them easy to overlook in budget planning. For every $100,000 in gross wages, an employer can expect to pay roughly $7,650 or more in FICA alone, before adding unemployment taxes. Failing to account for these costs leads to underfunded payroll budgets and potential cash flow problems. Tracking employer taxes separately also aids in quarterly estimated tax deposits, which are legally required and carry penalties if missed.
