Calculate your ideal freelance rate based on target income, billable hours, business expenses, and taxes. So you stop undercharging.
If your "target salary" is $80,000, the actual hourly rate to hit that take-home is much higher than $80,000 ÷ 2,000 = $40. You also need to cover:
The realistic multiplier from "W-2 salary equivalent" to freelance hourly rate is roughly 2-3x. So $80k W-2 = $80-$120/hr freelance, not $40/hr.
A 40-hour work week doesn't mean 40 billable hours. Realistic billable hours for most freelancers: 20-28 per week. Plan around 25 to leave buffer for sales, admin, training.
Freelancers don't get paid time off. If you take 4 weeks vacation + 1 week sick + holidays, you have ~46 working weeks. That's already 12% less revenue than 52 weeks.
