How the employee cost calculation works
The calculator builds the cost from five components instead of applying one flat payroll-tax percentage to every salary. That distinction matters once wages cross the Social Security cap.
- Base salaryis the employee’s annual cash pay before bonuses, commissions, or equity.
- Federal employer payroll taxes use the 2026 rules in IRS Publication 15: 6.2% Social Security up to the $184,500 wage base, 1.45% Medicare with no wage cap, and a configurable FUTA rate on the first $7,000 of wages. Additional Medicare Tax is employee-only and has no employer match.
- Benefits are an editable percentage of salary for employer-paid health, retirement, leave, and other plans. The 20% default is a planning placeholder, not a national benchmark. The March 2026 BLS compensation table includes legally required benefits, so copying its headline share here would double-count some payroll costs.
- State taxes and workers’ compensation use your annual employer estimate. State unemployment wage bases, experience ratings, credit-reduction rules, and job-class premiums vary; check the Department of Labor state UI guidance and your policy documents rather than assuming one nationwide rate.
- Other overhead is an annual amount for role-specific equipment, software, training, recruiting, and work space.
Worked examples with the 2026 wage cap
At the default $60,000 salary, the calculator estimates $3,720 of employer Social Security, $870 of Medicare, and $42 of FUTA after the full state credit. With 20% benefits, no added state cost, and $3,000 of overhead, the estimate is $79,632 annually, $6,636 monthly, or a 1.33× salary multiplier.
At a $200,000 salary, Social Security stops at $11,439 instead of continuing as a flat 6.2% of all wages. The same default assumptions produce $14,381 of federal employer payroll taxes and a $257,381 annual total. This is the correction the earlier flat 7.65% method missed.
This is a planning estimate, not tax, payroll, legal, or accounting advice. Confirm taxable wages, credits, state rules, benefit costs, and insurance premiums with your payroll provider or qualified adviser before approving a hiring budget.
Employee cost calculator FAQ
How much does an employee cost beyond salary?
The total depends on federal and state payroll costs, benefits, workers' compensation, and operating overhead. This calculator shows each component separately and turns the result into an annual total, monthly cost, and salary multiplier.
Why does Social Security stop increasing at $184,500?
For 2026, the employer's 6.2% Social Security share applies only to covered wages up to the $184,500 wage base. The calculator automatically caps this component at $11,439 per employee.
Does the employer match Additional Medicare Tax?
No. The employer Medicare share remains 1.45% with no wage cap. The 0.9% Additional Medicare Tax withheld from certain higher-paid employees does not have an employer match.
Is FUTA always 0.6%?
No. The standard FUTA rate is 6.0% on the first $7,000 of wages, and the maximum state unemployment credit can reduce it to 0.6%. Credit-reduction rules or late state payments can produce a higher effective rate, so the calculator leaves FUTA editable.
How should I enter state unemployment and workers' comp?
Use an annual estimate from your payroll provider, state unemployment account, and workers' compensation policy. State wage bases, experience ratings, job classifications, and local rules vary too much for one national percentage.
Is the 20% benefits input a national benchmark?
No. It is an editable planning placeholder. Enter the employer-paid cost of your actual health, retirement, paid-leave, and other plans without duplicating payroll taxes already calculated elsewhere.
