Common freelance fixed costs include health insurance, software subscriptions, equipment depreciation, coworking space fees, professional development, and estimated tax payments. Many freelancers underestimate these costs, leading to rates that are too low.

Variable costs for freelancers may include project-specific software licenses, subcontractor fees, stock assets, travel expenses, and platform commissions. Track these per-project costs to understand your true profit margin on each engagement.

Most freelancers can realistically bill 60-70% of their working hours, with the rest going to marketing, administration, and professional development. Plan for roughly 1,000-1,400 billable hours per year when calculating your break-even rate.
