Common questions
What should a freelance Autonomous Systems Engineer charge per hour?
Aim for about $100–$145/hour (mid $120). That starts from the salaried-employee equivalent of $82/hour and adds markup for self-employment tax (~15%), your own benefits, and unpaid/non-billable time.
Why is a contract rate higher than the salary hourly rate?
A $170,147 salary is ~$82/hour, but employees get employer-paid taxes, health insurance, 401k, and paid time off. As a freelance Autonomous Systems Engineer you cover all of that yourself and only ~70% of your time is billable — hence the markup.
What annual income does that rate produce?
At $120/hour with ~70% billable utilisation, a freelance Autonomous Systems Engineer grosses roughly $174,720/year before business expenses — comparable to the $170,147 salaried median once you account for benefits you now self-fund.
