Formula and Logic
This calculator uses standard small business accounting practices to compute total costs:
Employee Total Cost Per Year
Gross Salary + (Gross Salary Ă— Benefits Rate %) + (Gross Salary Ă— Payroll Tax Rate %) + Annual Overhead
Contractor Total Cost Per Year
(Annual Contractor Pay Ă— (1 + Management Overhead %)) Ă— Number of Contractors
Annual Contractor Pay is calculated based on your selected pay structure:
- Hourly: Hourly Rate Ă— Hours per Week Ă— Weeks per Year
- Monthly Retainer: Monthly Retainer Cost Ă— 12
- Project-Based: Project Cost Ă— Number of Projects per Year
Comparison Metrics
Cost difference is the absolute value between total employee and contractor costs. Savings percentage is the difference divided by the higher of the two total costs. Break-even rate shows how much contractor pay can increase before matching employee costs for a 1:1 hire ratio.
Practical Notes
These real-world considerations will help you interpret your results accurately:
- Employer payroll tax rates in the US typically range from 7.65% (FICA) to 15% including state taxes; check your local regulations for exact rates.
- Benefits rates for full-time employees often range from 20-30% of gross salary, covering health insurance, 401k matches, and paid time off.
- Contractor management overhead usually falls between 5-15% of total contractor pay, accounting for contract drafting, payment processing, and compliance checks.
- Contractors do not receive employment benefits, unemployment insurance, or workers’ compensation through your business, which reduces long-term liability.
- For seasonal or short-term work, contractors often have lower total costs even at higher hourly rates than full-time employees.

- Avoid unexpected overhead costs by factoring in hidden expenses like benefits and payroll taxes before hiring.
- Compare long-term vs short-term staffing costs to align with your business’s growth stage and cash flow.
- Justify staffing decisions to stakeholders with detailed, data-backed cost breakdowns.
- Adjust pay structures and overhead rates to test different scenarios for your trade, e-commerce, or service business.
Frequently Asked Questions
Does this calculator account for state-specific payroll taxes?
No, this tool uses a flat payroll tax rate input so you can enter your exact local, state, and federal tax obligations. Check with your accountant for region-specific rates.
Can I compare multiple employees and contractors at once?
Yes, use the “Number of Employees” and “Number of Contractors” fields to scale the calculation to your hiring plan. The results will show total costs for all hires in each category.
Are contractor project costs inclusive of materials?
No, enter only labor costs in the project-based field. Add material costs to your overhead or as a separate line item in your business accounting.
Additional Guidance
Pair this calculator with your business’s margin thresholds to determine if new hires will impact profitability:
- For e-commerce businesses, compare staffing costs against average order value and customer acquisition costs to ensure positive ROI.
- Trade businesses should factor in billable hour rates for employees and contractors to confirm that labor costs are covered by client billing.
- Review your results quarterly as tax rates, benefit costs, and contractor rates change over time.
- Consult a certified public accountant (CPA) to validate your inputs and ensure compliance with labor laws for contractors vs employees.
