Employees see their own payroll tax withholding, but employers owe a separate, additional set of payroll taxes on top of gross wages — a real cost that's easy to underestimate when budgeting for a new hire. This calculator finds the employer-side payroll tax burden — Social Security, Medicare, and FUTA — on a given amount of gross wages.
How it works
Enter the gross wages and the applicable Social Security, Medicare, and FUTA rates (defaults reflect commonly-cited flat percentages). The calculator applies each rate to the gross wages and sums them for the total employer tax burden.
- Enter gross wages ($).
- Enter social Security rate (%).
- Enter medicare rate (%).
- Enter fUTA rate (%).
- Click Calculate to see your results.
Examples
$5,000 in gross wages
At standard rates, this generates $310 in Social Security tax, $72.50 in Medicare tax, and $30 in FUTA tax — a total employer burden of $412.50.
Who should use it
- Budgeting the true cost of a new hire beyond their gross salary.
- Estimating employer payroll tax obligations for cash flow planning.
Industry applications
- Small business payroll and HR planning
- Accounting and bookkeeping
Advantages
- Breaks down each tax component separately for transparency.
- Uses adjustable rates so it stays accurate as tax rates change.
Limitations
- Does not automatically apply wage base caps — enter wages within the applicable cap for full accuracy near that threshold.
Common mistakes to avoid
- Forgetting that the Social Security wage base cap means this tax doesn't apply indefinitely to high earners' wages within a year.
- Using outdated tax rate figures instead of checking current IRS-published rates for the applicable tax year.
Best practices
- Verify current Social Security, Medicare, and FUTA rates (and any wage base caps) with the IRS or your payroll provider each year, since they can change.
Tips
- When budgeting for a new employee, remember the true cost is gross wages plus this employer payroll tax burden — often referred to as the "fully loaded" cost of an employee.
