To calculate a contractor’s rate, you need to account for their base compensation, self-employment costs, benefits they don’t receive as an employee, and any location-based or industry-specific adjustments. Contractor rates are typically higher than employee salaries to reflect these additional responsibilities and risks.
What’s the basic formula?
A common formula used by businesses is:
Contractor rate = (Employee salary equivalent × 1.2 to 1.5) / billable hours per year
This markup accounts for:
- Lack of employer-paid benefits (health insurance, PTO, pension)
- Business expenses (equipment, software, insurance, taxes)
- Unpaid time (holidays, sick leave, downtime)
- Country-specific costs or currency adjustments
For example, if a full-time salary is $100,000:
→ $100K × 1.3 = $130K
→ $130K ÷ 1,800 billable hours = ~$72/hour contractor rate
Where does this apply?
Contractor rate calculations vary globally, especially where taxes, healthcare, and benefits are handled differently (e.g., U.S. vs. EU). Rates may also be project-based, hourly, or daily depending on contract terms and industry norms.
Who calculates the rate?
Both businesses and contractors may estimate rates — businesses for budgeting or offer purposes, and contractors to ensure fair compensation.
