How It Works

How to Calculate Total Employee Cost

Formula

Total Cost = Salary + (Salary x Benefits%/100) + Payroll Taxes

The true cost of an employee is typically 25-40% above their base salary. This "burden rate" includes health insurance, retirement contributions, payroll taxes, workers comp, and other benefits.

Worked Example

An employee with a $65,000 salary, 25% benefits cost, and $5,000 in employer payroll taxes.

salary = 65000benefits_pct = 25taxes = 5000
  1. 01Benefits cost = $65,000 x 25% = $16,250
  2. 02Total annual cost = $65,000 + $16,250 + $5,000 = $86,250
  3. 03Monthly cost = $86,250 / 12 = $7,187.50
  4. 04Burden rate = ($16,250 + $5,000) / $65,000 x 100 = 32.69%
