Freelance Profit Margin Calculator

Formula and inputs

Revenue is billed income. Direct costs are what specific projects consume: subcontractors, project software, and travel. Operating expenses hold the practice's overhead: tools, insurance, workspace, equipment depreciation, accounting, and marketing. Net margin is what the business earns; what you pay yourself from it is a separate decision the margin makes possible or not.

Example scenario

Solo developer practice audit

A freelance developer billed $9,500 a month on average. Direct costs ran $700: an occasional subcontracted designer and project tooling. Overhead came to $2,800 monthly: software, health insurance, retirement set-aside, coworking, equipment, and bookkeeping.

• -Revenue: $9,500/month
• -Cost of goods sold: $700
• -Operating expenses: $2,800
• -Industry: consulting benchmarks

Net profit is $6,000 monthly, a 63 percent net margin, which is the developer's actual pre-tax compensation pool. Against a salaried alternative, the comparison must subtract self-employment tax and the benefits already counted here, and the result is closer than the $114,000 billing figure implies, though still favorable.

Common mistakes

• -Reading gross billings as income and discovering the gap at tax time.
• -Leaving health insurance, retirement, and equipment out of overhead because they feel personal.
• -Ignoring unbilled time: a 63 percent margin at 60 percent utilization is a different business than the same margin at 90 percent.

How to interpret the output

• -If net margin is strong but total profit is below a fair salary, the practice has a volume or rate problem, not a cost problem.
• -Subcontracting that drops margin below 50 percent on the subcontracted work is usually buying convenience, which is fine if chosen knowingly.
• -Watch overhead creep: solo practices accumulate subscriptions at a rate that compounds quietly.
