Employer Payroll Cost Calculator

Enter the salary, payroll tax rate, and benefits rate to find the total employer cost.

How it is calculated

Both employer on-costs are percentages of the same base salary and are simply added together. added cost = salary × (payroll_tax_pct + benefits_pct) ÷ 100 and total cost = salary + added cost. The salary is the yearly gross pay you agree with the employee, and the result is the yearly cost to the employer. Payroll tax is the employer's own share of social charges, and benefits cover items such as health cover, retirement matching and paid leave, expressed together as one percentage of salary. The tool does not look up the rates, which vary by country, state and salary level, and it does not cap contributions at wage ceilings. Zero rates are allowed. A negative value, an empty field or a payroll tax above 100% gives no result. Equipment, training, recruitment and office costs are outside the figure.

Worked example

An employee has a base salary of 60000. You estimate employer payroll taxes at 8% and benefits at 20% of salary. Step 1: combined on-cost rate = 8 + 20 = 28%. Step 2: added cost = 60000 × 28 ÷ 100 = $16,800.00. Step 3: total cost = 60000 + 16800 = $76,800.00 a year, or 6400 a month. The employee sees 60000 gross, but the business budgets 28% more than that for them.

Common mistakes

  • Entering the employee's own tax and contribution rate instead of the employer's share. The employee's deductions come out of their pay and do not add to your cost.
  • Typing a monthly salary and reading the result as annual. The result keeps the same period as the salary you entered.
  • Entering the benefits value as a currency amount rather than a percentage of salary. Divide the yearly benefit cost by salary and multiply by 100. A payroll tax above 100 gives no result, but a benefits figure is not capped, so a mistyped 2000 would be accepted.
  • Applying one payroll tax rate to a high salary when contributions stop at a wage ceiling. The tool applies the rate to the whole salary.
  • Leaving out costs beyond tax and benefits, such as equipment, software seats, training and recruiting, then calling the result the full cost of a hire.

About this calculator

The salary an employer quotes an employee is only part of what it actually costs to keep that person on the payroll. On top of base salary, employers must pay their share of payroll taxes — such as Social Security and Medicare contributions and unemployment insurance in the U.S. — and typically fund benefits like health insurance, retirement matching, and paid leave, all of which add up to what HR and finance teams call the fully loaded cost of an employee.

This fully loaded figure, often running 25–40% above base salary depending on the benefits package and jurisdiction, is the number businesses actually budget against when deciding whether to hire, not the salary line alone — using base salary for headcount planning routinely understates true labor cost. Salary plus payroll tax plus benefits, each set as a rate on pay, adds up to the full yearly cost of employing that person.
