Freelance Rate Mathematics & Utilization Formulas
Freelance pricing models account for unbillable business operations and self-employment tax burdens:
1. Annual Billable Hours Capacity
Billable Hours = [ (52 - Vacation) × Hours/Wk - (Sick + Holiday) × 8 ] × (Billable % / 100)
2. Tax-Adjusted Minimum Client Hourly Rate
Tax-Adjusted Rate =
(Target Net + Business Expenses) ÷ Billable Hours1 - (Tax Rate % / 100)
Step-by-Step Rate Derivation Breakdown
Step 1: Compute Total Annual Billable Hours
46 working weeks × 40 hrs/wk @ 70% billable = 1,288 billable hours/year (28 hrs/wk).
Step 2: Aggregate Total Gross Revenue Requirement
($80000 target salary + $12000 expenses) adjusted for 25% tax = $122,667 required gross revenue.
Step 3: Establish Client-Facing Minimum Hourly Rate
Client Rate=$96/hr ($533 Day Rate)
