Hours required weekly to hit target income at given hourly rate and billable percentage

Freelance Capacity Math

Freelance capacity planning works backward from target income. Target divided by hourly rate equals billable hours needed annually. That divided by billable percentage (portion of work hours actually billable) equals total hours needed. Divided by working weeks gives required weekly hours. Most freelancers discover they can't sustainably hit optimistic income targets because required total hours exceed 50-55 weekly — the practical limit before burnout. The calculator makes capacity constraints visible before committing to unrealistic targets.

Typical Freelance Billable Rates

Established consultants: 60-70% billable. Mid-career freelancers: 50-60%. Early-career freelancers: 30-50% (more time on business development, unpaid work). Agency employees: 65-80% billable (more structure). Solo service businesses: 40-55% (running business consumes non-billable hours). Higher billable percentage requires strong systems, established client base, and disciplined time management. Billable percentage less than 40% signals business development issues or over-investment in administrative tasks.

Worked Example for Mid-Career Freelancer

Target income 100,000. Hourly rate 100. Billable 60%. Working weeks 48. Billable hours annual 1,000. Hours per week billable 20.8. Total hours per week 34.7. Equivalent 4.3 work days weekly. Feasible target — 35 hour total work week is sustainable. Increasing target to 150,000 with same parameters requires 52 total hours weekly — edge of sustainable. 200,000 requires 69 hours weekly — unsustainable long-term. Either raise rate, improve billable percentage, or accept lower income target.

What the Calculator Does Not Model

Specific ramp periods where billable percentage starts low. Seasonal patterns affecting specific months. Vacation and illness reducing effective weeks. Rate increases achievable over time. Specific industry norms for billable hours. Team scaling (hiring subcontractors to extend capacity beyond personal hours). The calculator shows snapshot capacity math; real freelance businesses involve capacity building trajectory and strategic scaling decisions.

Increasing Capacity Without Working More

Raise hourly rate annually — biggest lever without adding hours. Improve billable percentage through better systems (CRM, time tracking, templates). Add subcontractor capacity (project-by-project contractors extend hours available). Productize services (fixed-price packages with predictable hours). Drop lowest-profit clients to focus time on highest-value work. Each lever compounds; combined approach can increase effective income 50-100% without more working hours. Calculator shows current constraint; strategy determines how to expand capacity intelligently.
