What this calculator measures
Salary is only one part of employer cost. Benefits, employer payroll charges, insurance, equipment, workspace, software, recruiting, and administration can materially change the employee total. Contractor cost depends on rate, approved hours, duration, and any agency or platform fees.
Financial comparison does not determine legal classification. Control, independence, integration, duration, local labor rules, and tax obligations may override the label used by the parties.
Common use cases
Use this model when the inputs describe the same decision, period and customer or product scope.
- Compare modeled annual employer cost with the cost of hiring a contractor for a defined schedule.
- Use the result with the recorded inputs: Employee annual salary, Benefits as % of salary, Employer taxes and insurance, Annual employee overhead, Contractor hourly rate, Contractor hours per week, Contractor working weeks.
- Compare multiple scenarios before making a employment & freelance decision.
Formula
The estimate compares entered financial costs and does not determine worker classification or legal obligations.
Formula breakdown
- Employee cost should include salary plus employer-paid payroll taxes, benefits and other relevant employment costs.
- Contractor cost should include the contract rate and any additional fees or management costs borne by the business.
Employee vs Contractor: formula, inputs and interpretation
The estimate compares entered financial costs and does not determine worker classification or legal obligations.

Example input values
Worked calculation and answer
A $75,000 salary with benefits equal to 18%, employer taxes and insurance of 9%, and $8,000 overhead produces a modeled employee cost of $103,250. A contractor at $65 per hour for 30 hours over 48 weeks costs $93,600 before any agency fee, creating a modeled difference of −$9,650.
Variable definitions and checks
- Employee annual salary (salary): Use a numeric value at least 0. Check its reporting period and definition before comparing it with other inputs.
- Benefits as % of salary (benefits): Use a percentage value at least 0. Check its reporting period and definition before comparing it with other inputs.
- Employer taxes and insurance (payroll): Use a percentage value at least 0. Check its reporting period and definition before comparing it with other inputs.
- Annual employee overhead (overhead): Use a numeric value at least 0. Check its reporting period and definition before comparing it with other inputs.
- Contractor hourly rate (contractorRate): Use a numeric value at least 0. Check its reporting period and definition before comparing it with other inputs.
- Contractor hours per week (hours): Use a numeric value at least 0. Check its reporting period and definition before comparing it with other inputs.
- Contractor working weeks (weeks): Use a numeric value at least 0. Check its reporting period and definition before comparing it with other inputs.
When the result may mislead
The calculation reflects the variables named above, not unentered taxes, platform terms, reporting delays, financing charges or external forecasts. For comparisons, keep the same units and reporting period and change one assumption at a time.
Scenario comparison
An employee with $80,000 salary plus $20,000 of employer taxes and benefits costs about $100,000 before other overhead.
A contractor billing $60 per hour for 1,600 hours costs $96,000 before agency fees or other charges.
How to interpret the result
Compare the same work scope and expected output. Contractors may bring specialist speed or flexibility, while employees may provide continuity, availability, institutional knowledge, and broader responsibilities.
Run several utilization scenarios. Contractor hours can expand, and employee cost per productive hour changes with leave, training, meetings, and workload.
What a good result looks like
The cheaper nominal option is not necessarily the better option; continuity, control, skill scarcity and workload duration also matter.
Compare equivalent scope and expected productive capacity.
Common mistakes
- Do not compare employee salary alone with a fully loaded contractor invoice.
- Do not use the calculator to determine legal worker classification.
When this metric can mislead you
Actual employee cost varies with benefits, leave, equipment and jurisdiction.
Worker-classification law can make a financially attractive contractor arrangement legally inappropriate.
How to use the result in a decision
Use the calculation for budgeting after defining the same work scope for both options.
Confirm employment classification and tax obligations separately with qualified guidance.
Assumptions and limitations
- All employee percentages are applied to base salary.
- Contractor hours and weeks are billable at one rate.
- Currency and time period are consistent.
- Worker classification, severance, overtime, tax, recruitment risk, productivity, and contract terms require separate review.
Frequently asked questions
Should paid leave be added to employee cost?
Salary normally continues during paid leave, so it is already included in annual salary dollars but affects productive-hour comparisons.
Should contractor tax be added?
The hiring organization generally compares the invoiced cost it expects to pay. Tax treatment and withholding depend on jurisdiction and classification.
Can the cheaper option still cost more overall?
Yes. Rework, turnover, management time, knowledge loss, delays, and classification risk can outweigh the headline financial difference.
