Three Rate Tiers
Tax Estimation
The income breakdown uses these simplified effective rates:
- Federal Income Tax: 24% effective rate (assumes typical freelancer bracket with standard deduction)
- Self-Employment Tax: 15.3% (Social Security 12.4% + Medicare 2.9%)
- State Income Tax: Based on your selected state's flat or average effective rate
Note: 8 states have no income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming.
Why 25 Billable Hours/Week?
Most freelancers spend 40–50% of their time on non-billable work: client acquisition, emails, invoicing, admin, learning, and marketing. If you work 40 hours/week, realistically only 20–25 of those are billable. Overestimating leads to underpricing.
⚠️ Disclaimer
This is a planning estimate. Actual taxes depend on deductions, filing status, business structure, and IRS rules. The rates shown are simplified effective rates, not marginal rates. Consult a CPA or tax professional for precise numbers before making financial decisions.
