Why are billable hours different from working hours?
An independent worker may spend time selling, invoicing, learning and managing projects. Those hours are work, but the customer may not be billed for them. A realistic rate therefore starts with the number of hours that actually produce revenue.
What we put into the calculator
The illustrative annual income goal is $60,000, annual business expenses are $6,000, a simple 25% tax-planning buffer applies to the income goal, and 46 working weeks contain 20 billable hours each. This is not a tax-liability calculation.
The numbers behind the result
| Desired income after planning buffer | $60,000 |
|---|---|
| Revenue toward goal before 25% buffer | $80,000 |
| Business expenses | $6,000 |
| Total revenue target | $86,000 |
| Billable hours (46 × 20) | 920 |
| Average billed hourly rate | $93.48/hr |
What the result means
The model divides $60,000 by 0.75 to provide room for the chosen planning buffer, adds $6,000 in expenses, and spreads the resulting $86,000 across 920 billable hours. The answer is an average collected rate, not a suggested market price or a promise of profitability. Discounts, unpaid invoices and scope overruns would reduce actual receipts.
Try changing one assumption
Reduce billable hours from 20 to 15 per week. The same $86,000 revenue goal would then be distributed across just 690 hours, or approximately $124.64 per billed hour. Try increasing working weeks only if you expect to work them.
