How to price this work as a freelancer

The endpoints, environment access, sample maintenance, and technical review responsibilities define the quoted scope. Agree the inputs, deliverable, review rounds, and acceptance criteria before quoting. Include preparation, specialist review, equipment or licensing costs, and handover time where relevant. Price ongoing support separately from the initial engagement.

Start with the income you need to replace

Required hourly rate = (target salary + benefits budget + annual business expenses) ÷ (annual billable hours × share of revenue retained after fees).

For illustration, $100/hour × 25 billable hours/week × 48 working weeks = $120,000 revenue. After $20,000 in business expenses, that leaves $100,000 profit before personal taxes. Replacing a $100,000 salary plus $15,000 in benefits under those assumptions takes $112.50/hour, with no percentage fees.

These are editable planning assumptions, not rates surveyed for api documentation writer work. Your personal taxes, location, contract terms, and workload still affect the comparison.
