How to Read Your Results
Maximum client capacity is the estimated number of average-sized clients that fit within target client-service hours.
Additional client capacity is zero when available client-service hours are negative or insufficient for one whole average client.
Available client-service hours show the difference between target client-work capacity and estimated current workload.
Current utilization compares current client workload with all workable team hours, not only the target client-service hours.
Team members needed is rounded up because part of a staff member cannot be scheduled as a whole staffing position.
Assumptions & Important Notes
- Each example treats clients as having a consistent average monthly workload.
- Available hours are monthly workable hours before utilization is applied.
- The selected utilization rate includes an allowance for non-client work.
- Examples do not model revenues, skills, service quality or timing of work.

Frequently Asked Questions
Can I use different hours per client for different service tiers?
Yes. Run separate estimates by client tier, or use a weighted average based on the mix you expect to serve.
Why do lower utilization targets reduce client capacity?
A lower target reserves more of the team's workable hours for non-client and unplanned work, leaving fewer hours for recurring client service.
Should I use a busy-month or average-month workload?
Use the period you are planning for. A busy-month estimate is generally more suitable for short-term intake and staffing planning.
What if the calculator shows capacity for less than one additional client?
Additional client capacity is rounded down to zero, although the remaining hours may still help absorb variable work.
