How to Read Your Results
Daily billable hours show the chargeable portion of a typical workday.
Monthly billable hours are capacity estimates, not guaranteed client demand.
Monthly billings are gross fees associated with the estimated hours.
Annual billings use only the working months you enter.
Compare several utilization and rate scenarios rather than relying on one projection.
Assumptions & Important Notes
- The hourly rate is the average realized billing rate.
- Utilization applies consistently throughout each working month.
- All estimated billable time is invoiced at the stated hourly rate.
- Results exclude expenses, taxes, discounts, write-offs and unpaid invoices.

Frequently Asked Questions
Can I use fewer than 12 working months?
Yes. Using fewer months can model planned leave, seasonal closure or a partial operating year.
Why are my results shown before expenses?
The calculator models fee billing capacity. Costs and taxes vary by practice and are not included.
Should I use one rate for all services?
Use an average realized hourly rate, or run separate scenarios for service lines with materially different rates.
