Calculate the minimum hourly and project rate needed to achieve target annual net income after self-employment taxes, overhead, and non-billable time.
Accounts for the reality that only 50-70% of working hours are billable client time, while the rest is administration, marketing, and business development.
Beginner freelancers mistakenly assume 40 hours per week of client billing. In practice, invoicing, sales calls, marketing, and self-learning consume 30-40% of standard work weeks.
$120,000 net target, $10,000 expenses, 4 weeks vacation, 60% billable utilization.
Result: $157 / hour ($1,256 / day)
A common rule of thumb for US freelancers is to set aside 25% to 35% of every payment for federal self-employment and state income taxes.
