Freelance Project Profit Calculator

Freelance project profit is what is left after the hours worked (priced at the freelancer's opportunity cost), direct costs (subcontractors, software, materials), and tax on the residual. The headline project fee rarely equals the real profit. A project priced at 5,000 with 60 hours of work valued at 75 per hour and 300 in direct costs has 4,500 of time cost and 4,800 of total cost before tax — leaving a gross profit of only 200, well below what the fee suggests.

What the result means

The result is the project's net profit after all costs and tax. A negative figure means the project consumed more time-value and direct costs than the fee covered — in other words, the same hours spent elsewhere at the opportunity-cost rate would have produced higher net income. A positive figure indicates the fee covered all costs with margin to spare. The Effective Net Per Hour secondary metric divides the net profit by hours worked, giving a directly comparable hourly figure that can be set alongside the opportunity-cost rate.

Quick example

With project fee 5,000, hours worked 60, hourly opportunity cost 75, direct costs 300, and tax rate 25%, the calculation works out as follows: time cost equals 60 × 75 = 4,500. Gross profit equals 5,000 − 4,500 − 300 = 200. Tax at 25% on the gross profit equals 50. Net profit equals 150. Gross margin works out to 4% of the fee; effective net per hour is 150 ÷ 60 = 2.50.

Which inputs matter most

The inputs are Project Fee, Hours Worked, Hourly Opportunity Cost, Direct Costs, and Tax Rate. Hours worked and opportunity cost together drive the largest cost component for most service projects — the time cost (hours × rate) typically dominates the equation. Direct costs are usually a smaller proportional input but can shift the margin sharply on subcontractor-heavy projects. The fee is the only input on the revenue side, so any margin improvement on a fixed fee has to come from the cost side.

How the math works

Time cost equals hours worked multiplied by hourly opportunity cost. Gross profit equals project fee minus time cost minus direct costs. Net profit equals gross profit multiplied by (1 minus tax rate as a decimal) when gross profit is positive; when gross is negative, the loss is shown as-is rather than reduced by a tax shield (the shield only applies if other profitable work absorbs the loss). Gross margin equals gross profit divided by fee. Effective net per hour equals net profit divided by hours worked.

What this calculation does not capture

Multi-project averaging — a portfolio of mixed-profitability projects may make a single low-margin engagement worthwhile for reasons (referral pipeline, portfolio diversification) that this single-project view does not surface. Scope creep that drives hours above the original estimate during the work. Future revenue effects (repeat business, testimonials, case studies) tied to the engagement. Quarterly tax estimate timing in jurisdictions that require it. The output is one project's economics in isolation.
