Labor Cost Calculator

Find the true hourly and annual cost of an employee by loading the base wage with payroll tax, benefits, and overhead — then scale it across your team.

Quick Facts

Formula
Burdened rate = Wage × (1 + Tax/Benefits% + Overhead%)
The load rates are applied on top of the base wage, not subtracted from it.
Model
Fully burdened labor cost (true cost of an employee)
Standard employer-cost method used for staffing budgets and hiring decisions.

How the Labor Cost Calculator works

The wage you offer an employee is only part of what it costs to employ them. Employers also pay payroll taxes, typically fund benefits, and carry overhead — equipment, training, workspace, administrative support — tied to the role. This calculator loads those costs onto the base wage to produce a fully burdened hourly rate, then scales that rate into an annual cost per employee and a total labor cost across your headcount.

The formula

For a base hourly wage W, a combined payroll tax and benefits rate T, and an overhead rate O (both expressed as decimals, e.g. 25% = 0.25), the fully burdened hourly rate is:

Burdened rate = W × (1 + T + O)

Multiplying the burdened rate by hours worked per week and weeks worked per year gives the annual cost per employee, and multiplying that by headcount gives the total annual labor cost:

Annual cost per employee = Burdened rate × Hours/week × Weeks/year
Total annual labor cost = Annual cost per employee × Number of employees

Worked example

Take a $25/hour base wage, 40 hours a week, 52 weeks a year, a 25% payroll tax and benefits load, and a 15% overhead load. The combined load is 40%, so the burdened rate is $25 × 1.40 = $35.00 per hour. Over 2,080 hours a year (40 × 52), that employee costs about $72,800 per year — roughly $20,800 above the $52,000 the base wage alone would suggest ($25 × 2,080). For a team of 10 employees at the same rate, total annual labor cost is about $728,000.

What moves labor cost most

  • Base wage: every load rate is a multiplier on the wage, so a higher base wage amplifies the dollar impact of the same percentage load.
  • Payroll tax and benefits load: statutory payroll taxes are fairly fixed, but benefits generosity (health coverage tier, retirement match, paid leave funding) varies widely and is usually the largest swing factor.
  • Overhead load: equipment-heavy or highly supervised roles carry more overhead than roles that need little more than a desk and a laptop.
  • Hours and headcount: annual and total cost scale linearly with hours worked per year and number of employees, so small rate changes compound quickly across a large team.

Assumptions and scope

This calculator applies flat percentage load rates on top of a single base wage; it does not model overtime premiums, tiered benefit costs, jurisdiction-specific tax brackets, or part-year proration. Payroll tax rates, benefit costs, and overhead vary by location, industry, and company policy, so treat the load-rate inputs as estimates you supply, not fixed constants. This tool performs computation only and is not personalized financial, tax, or HR advice — confirm exact payroll tax rates and benefit costs with your payroll provider or accountant before budgeting or pricing decisions.

Frequently Asked Questions

How is fully burdened labor cost calculated?
Multiply the base hourly wage by (1 + payroll tax and benefits rate + overhead rate) to get the fully burdened hourly rate. Multiply that rate by the hours worked per week and the weeks worked per year to get the annual cost per employee, then multiply by headcount to get the total annual labor cost.
What counts as payroll tax and benefits load?
Employer-side payroll taxes (Social Security, Medicare, and federal or state unemployment insurance) plus the cost of benefits you provide, such as health insurance, retirement contributions, and paid time off funding, expressed as a percentage of base wages.
What counts as overhead in this calculator?
Overhead covers costs beyond direct pay and mandated benefits, such as equipment, software licenses, training, workspace, and administrative support attributable to the role. Enter it as a percentage of base wages, or leave it at 0% to see payroll tax and benefits load on their own.
Why is the fully burdened rate higher than the wage I quote an employee?
The wage you quote an employee, such as $25 per hour, is only the base pay. Employers also owe payroll taxes and typically fund benefits on top of that wage, so the true cost of an hour of work is higher, commonly 25% to 50% above the base wage depending on the benefits package and overhead.
