Retainer + Hourly Rate Calculator
The hourly rate that pays your bills is the rate that — multiplied by the billable hours you actually have, after taxes and business expenses — lands at your target take-home. This calculator solves it both directions. Enter a take-home goal and get the rate, or enter a rate and see the realistic annual take-home. Source-cited to the SBA, IRS Pub 535, and BLS.
After off-weeks budgeted.
Working weeks × billable hrs / wk.
Pre-tax, pre-expense top line.
Combined SE + federal + state, applied to revenue net of expenses.
Gross revenue minus annual business expenses, before income tax.
Green = take-home. Red = taxes. Gray = business expenses. The green portion is what you actually keep per dollar of client revenue.
| Hourly rate | Projected take-home |

| $50 / hr | $38,500 |
| $75 / hr | $57,750 |
| $100 / hr | $77,000 |
| $125 / hr | $96,250 |
| $150 / hr | $115,500 |
| $200 / hr | $154,000 |
| $250 / hr | $192,500 |
| $300 / hr | $231,000 |
Take-home at each rate, holding your current weeks / hours / tax / expense inputs constant.
- Most freelancers underestimate non-billable time. 60% billable utilization is realistic; 70%+ requires deliberate process or sales support.

Freelance rate math at a glance
Key facts
- The rate formula
- Required hourly rate = [desired take-home ÷ (1 − effective tax rate) + business expenses] ÷ annual billable hours, where billable hours = (52 − off-weeks) × billable hours per week. Solve backward from the take-home target — the rate is a derived input, not a guess.
- Realistic utilization
- 60% billable utilization is the realistic median for solo freelancers and consultants — about 25 invoiced hours on a 40-hour week. The other 40% goes to business development, proposals, admin, and unbilled project overflow.
- Budget the time off
- Budget at least 8 off-weeks per year into the rate — 4 weeks vacation, 1 sick, 2 federal-holiday weeks, 1 admin week — leaving 44 working weeks. Pricing as if you'll work 50 weeks and then taking 8 off is how freelancers end up underwater.
- Effective tax rate
- 30% is the working median combined effective tax rate for U.S. self-employed in the $100K–$150K bracket (~15.3% SE tax deductible at half, ~15–22% federal, 0–9% state). High-tax states at $200K+ push closer to 40%; no-income-tax states land nearer 25–27%.
- Retainer pricing
- Price a retainer at your hourly rate × estimated monthly hours × 1.1 to 1.3 — a premium for predictability and reserved capacity. Below 1.0× leaves money on the table; above 1.3× clients revert to hourly.

What this means
The hourly rate that pays your bills is not the rate that sounds impressive on a sales call — it's the rate that, multiplied by the billable hours you actually have, generates the gross revenue that survives taxes and business expenses to land in your bank account at your target number. Most freelancers price backward from a peer's rate or a vague "market rate" and end up either overworked at $75/hr or under-billed at $200/hr without knowing which. Pricing forward from a take-home target removes the guesswork.
The two assumptions that move this number more than anything else are billable utilization and effective tax rate. 25 billable hours per week (62% utilization on a 40-hour week) is what I consistently see as the realistic median for a solo operator across service practices — every hour above that has to come from sales support, productized scope, or process efficiency. 30% is the working effective tax rate for $100K–$150K self-employed in the U.S.; CA / NY / NJ at $200K+ runs closer to 40%. Get those two right and the calculator gives you a rate that actually clears.
Worked example
Solo consultant in Illinois targeting a $150,000 annual take-home. Effective tax rate ~30% (15.3% SE tax with the deductible half, ~22% federal marginal at this income, 4.95% IL flat). 4 weeks vacation, 1 sick, 2 holidays, 1 admin = 8 off-weeks → 44 working weeks. 25 billable hrs/wk → 1,100 billable hrs/yr. Annual business expenses of $18,000 (health insurance ~$10K, software / accounting ~$5K, retirement / disability ~$3K).
Required gross = $150,000 ÷ 0.70 + $18,000 = $232,286. Required hourly rate = $232,286 ÷ 1,100 = ~$211/hr. The takeaway: the consultant who's been quoting "$175/hr because that's what my last gig paid" is roughly $40K/yr short of their stated take-home goal, and the gap is invisible until the math is run. Either the rate has to move up, the off-weeks have to come down, or the income target has to come down — there is no fourth lever.
