Work out the hourly and day rate you need as a freelancer from your target income, expenses, taxes and billable hours. Free, private, runs in your browser.
Gross revenue needed = (take-home income + expenses) ÷ (1 − tax rate). Billable hours = hours per week × billable share × working weeks. Your minimum rate is gross revenue ÷ billable hours. Most freelancers bill only 50–70% of the hours they work, so leave room for admin, sales and time off.
