How the calculation works
Required hourly rate = gross revenue needed ÷ total billable hours per year, where:
- Gross revenue needed (before tax) = target income + business expenses + self-funded benefits.
- Gross revenue with tax buffer = gross revenue needed ÷ (1 − tax buffer %). A 30% buffer means you gross up your target so that 30% of gross revenue covers taxes, leaving the target after tax.
- Total billable hours = (52 − weeks off) × billable hours per week.
The tax buffer is a planning estimate, not a precise tax calculation. Use the quarterly tax calculator or the 1099 vs W2 comparator for a calculation based on actual 2026 brackets.
Worked example
A freelancer targeting $80,000 take-home, billing 25 hours per week for 48 weeks per year (4 weeks off), with $5,000 in annual business expenses, $8,000 in self-funded benefits, and a 30% tax buffer:
| Item | Amount |
|---|---|
| Target income + expenses + benefits | $93,000 |
| Gross-up for 30% tax buffer ($93,000 ÷ 0.70) | $132,857 |
| Total billable hours (48 × 25) | 1,200 |
| Required hourly rate | $110.71 |
| Required day rate (8 hours) | $885.68 |
How billing more hours changes the rate
Increasing to 40 billable hours per week with no weeks off (2,080 hours/year) drops the required rate to about $63.87/hour. The gross revenue needed doesn't change — it just spreads across more hours.
Assumptions and limitations
- The tax buffer is a flat gross-up percentage, not a tax calculation. A 30% buffer is a common planning figure, but the right number depends on your actual income, deductions, and filing status. Use the quarterly tax calculator for a bracket-based estimate.
- Non-billable time (sales, admin, unpaid revisions, professional development) isn't modeled. If a third of your working hours are non-billable, your effective billable hours are much lower than the input suggests.
- This is a pricing floor, not a market rate. The calculator tells you the minimum you need to charge — whether the market will pay it is a separate question.
Frequently asked questions
- What tax buffer percentage should I use?
- For most single freelancers earning $50,000–$150,000, 28–32% is a reasonable starting point. Lower earners can use 22–25%; higher earners above $150,000 should use 35–40%. When in doubt, use the quarterly tax calculator to see your actual bracket-based estimate.
- Should I include 401(k) contributions in the tax buffer or as a benefit cost?
- Retirement contributions are tax-advantaged but still cost you cash. Enter them in "benefits you need to self-fund" to make sure the rate covers them. Don't double-count by also raising the tax buffer.
- Why does billing fewer hours raise my required rate so much?
- Your expenses and target income are fixed. The fewer hours you bill, the more each hour must carry. A freelancer billing 10 hours per week needs to charge several times more per hour than one billing 40, just to hit the same annual take-home.
