Most freelance rate calculators online lie to you. They start with hourly rate and walk you backward, which is exactly the wrong direction. This one starts with what you actually want to take home, then layers in self-employment tax, business expenses, vacation, and the simple fact that you can only bill about 60 percent of your working hours. Plug in your numbers below to see the rate you actually need to charge.
How the freelance rate formula works
Working backward from take-home is the only way to land on a rate that pays your real bills.
- Pre-tax income needed = target take-home ÷ (1 − effective tax rate)
- Total business income needed = pre-tax income + annual business expenses
- Working hours per year = working weeks × hours per week
- Billable hours per year = working hours × billable percent
- Hourly rate = total business income ÷ billable hours
- Project rate = hourly rate × estimated project hours × buffer multiplier
Worked example
A typical US-based independent consultant who wants $100,000 take-home.
| Target take-home | $100,000 |
| Effective tax rate | 30% |
| Annual business expenses | $8,000 |
| Working weeks per year | 46 |
| Hours per week available | 40 |
| Billable percent | 60% |
Result: Pre-tax income needed = $142,857. Total business income = $150,857. Working hours = 1,840. Billable hours = 1,104. Hourly rate = $137. Most freelancers are charging $80 to $100 in this scenario and wondering why they feel broke. The math says $137.
Why billable hours are usually 50 to 65 percent
Sales calls, accounting, contract negotiation, slack messages, follow-ups, downtime between projects, sick days. The 100 percent billable freelancer is a myth. Use 60 percent if you have steady retainer work, 50 percent if you are doing project-based work with gaps.
What expenses to include
Software subscriptions, hardware amortization, office or coworking, accountant, professional liability insurance, health insurance (if not paid out of take-home), training, conferences. The number is usually larger than freelancers think the first time they add it up.
Hourly vs project pricing
The calculator gives you both. Use hourly rate for retainers and ongoing work. Use project rate for fixed-scope work, and apply a 1.2 to 1.5 buffer multiplier because scope creep is real and you cannot pad your hours after signing.
Frequently asked questions
- Should freelancers really charge $137 an hour for $100k take-home?
- Yes, if you want to actually take home $100,000 after taxes, expenses, and unbillable time. Freelancers who charge less are subsidizing their clients by paying themselves below market.
- What effective tax rate should I use?
- In the US, single-member LLC or sole prop with $100k take-home usually lands at 28 to 35 percent effective once you stack federal income tax, self-employment tax, and state. Use 30 percent as a starting point unless you have specific knowledge of your tax situation.
- How do I justify a higher rate to clients?
- Show the math, not the rate. A calculator is more persuasive than an invoice. If a client sees the breakdown of why $137 is the floor, they negotiate scope instead of rate.
- Can I embed this on my freelance site?
- Yes. The Buildroy calculator has an embed snippet you can paste into Squarespace, Webflow, WordPress, Notion (via embed block), or any platform that supports HTML embeds. Use it as a lead magnet.
- What if I work part-time freelance?
- Cut working hours per week proportionally. The same math applies. A part-time freelancer wanting $50,000 take-home at 20 hours per week with the same other inputs lands around $137 per hour too, because the math is per-billable-hour.
