One Person Business Revenue Calculator
Most "how much can I make solo" math is fantasy because it forgets one thing: you can't bill 40 hours. This calculator applies a realistic capacity factor, then shows what the same business looks like if you productize. No signup — it runs entirely in your browser.
Your blended rate across all work.
Share of paid hours that actually get billed. Solo operators average 50–70%.
How this calculator works
The service model is honest arithmetic most calculators skip:
| Step | Formula |
|---|---|
| Billable hours / year | hours/week × weeks × capacity% |
| Gross revenue | billable hours × effective rate |
| Net take-home (pre-tax) | gross − (monthly overhead × 12) |
| $ per working hour | net ÷ (hours/week × weeks) |
The productized model multiplies price × customers × billing frequency. For recurring revenue it also estimates a churn-adjusted steady state so you don't over-count a number you can't hold.
Why capacity matters more than your rate
Doubling your rate is hard; protecting your capacity is a setting. A $100/hr operator billing 40% of their week makes less than an $80/hr operator billing 70%. That's the entire game of a one person business — which is also why the leverage move is to stop selling hours. When you're ready to make that jump, the tech stack decision framework helps you choose the tools that productize delivery, and the how-to-start guide covers picking the first productized offer.
