How to Read Your Results
Annual billable hours represent estimated client-chargeable capacity, not total time worked.
Annual billable revenue is potential fee income before expenses, taxes, and collection delays.
Monthly figures are annual averages; actual accounting work can be seasonal.
Compare scenarios by changing one assumption at a time to see what drives the result.
Use the realized hourly rate for fixed-fee work, not only a published hourly rate.
Assumptions & Important Notes
- Each example applies the same utilization rate throughout the year.
- The hourly rate is treated as the average realized rate for all billable work.
- Revenue is calculated from time billed and does not include VAT, sales taxes, or expenses.
- The examples use dollars only for illustration; the formula works with any currency.

Frequently Asked Questions
Can I use these examples for a fixed-fee accounting practice?
Yes. Use an effective hourly rate calculated as the expected fixed fee divided by the expected delivery hours.
Why do the examples show monthly averages?
They turn the annual estimate into a simple planning benchmark, although actual monthly workload may vary.
What happens if utilization increases?
Billable hours and estimated billable revenue rise in direct proportion if the schedule and hourly rate stay the same.
What happens if the hourly rate changes?
Estimated revenue changes in direct proportion, while billable-hour capacity does not change.
