A freelance Data Scientist should charge about $75–$105/hour (≈ $680/day). That's built up from the salaried median of $122,407 — not the naive $59/hour, because contractors cover their own taxes, benefits, and unpaid time.
Suggested rate range
Day rate ≈ $680. At the market rate with ~70% billable time, that's roughly $123,760/year gross. Raise rates for specialised work, rush timelines, or high-value clients.
Common questions
What should a freelance Data Scientist charge per hour?
Aim for about $75–$105/hour (mid $85). That starts from the salaried-employee equivalent of $59/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 $122,407 salary is ~$59/hour, but employees get employer-paid taxes, health insurance, 401k, and paid time off. As a freelance Data Scientist 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 $85/hour with ~70% billable utilisation, a freelance Data Scientist grosses roughly $123,760/year before business expenses — comparable to the $122,407 salaried median once you account for benefits you now self-fund.
