How to use this calculator
- Enter assigned full-time-equivalent staff.
- Set scheduled hours and working days for the same period.
- Enter the observed productive processing rate.
- Apply the share of time genuinely available for this work.
Estimate how many purchase orders a procurement team can process from staffing, productive hours, handling rate, and utilization.
Capacity = Staff × Hours per day × Working days × Orders per productive hour × Utilization
The result estimates maximum orders processed during the entered period at the stated productive utilization.
This is a throughput estimate. Complexity mix, rework, system downtime, and batching should be reflected in the observed processing rate or utilization.
Four staff × 8 hours × 22 days × 2 orders per hour × 75% gives capacity of 1,056 orders, based on 528 productive hours.
Only if rework is already reflected in the observed processing rate or productive utilization.
Yes. Full-time-equivalent staffing can be entered as a decimal when people split their time across duties.
It represents the share of scheduled time available for processing and cannot exceed all scheduled time.
Use a blended observed rate or calculate separate scenarios when complexity materially changes handling time.
No. It is a planning estimate based on the entered rate and availability assumptions.
