Choose how deeply to explain Capacity requirement
Capacity requirement: Convert unit demand and processing time into productive hours and required full-time capacity.
Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Capacity requirement to answer this question: convert unit demand and processing time into productive hours and required full-time capacity? Enter Units required per period, Processing minutes per unit, Productive hours per FTE, and 2 other inputs; the calculator shows Required full-time capacity. Try changing one number and watch what happens to Required full-time capacity. The answer tells you Required full-time capacity.
Age 15Explain it to a 15-year-oldConnect it to the formula
Productive hours should exclude leave, meetings, maintenance and ordinary downtime. A buffer protects the plan from demand and process variability. The rule is Required FTE = demand × minutes per unit ÷ 60 ÷ productive hours per FTE × buffer. Its input values are Units required per period, Processing minutes per unit, Productive hours per FTE, Capacity buffer (%), Current available FTE, and the main result is Required full-time capacity. Try changing one number and watch what happens to Required full-time capacity.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Required FTE = demand × minutes per unit ÷ 60 ÷ productive hours per FTE × buffer, evaluated from Units required per period, Processing minutes per unit, Productive hours per FTE, Capacity buffer (%), Current available FTE to produce Required full-time capacity. Productive hours should exclude leave, meetings, maintenance and ordinary downtime. A buffer protects the plan from demand and process variability. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Convert unit demand and processing time into productive hours and required full-time capacity.
Why the business model works
Productive hours should exclude leave, meetings, maintenance and ordinary downtime. A buffer protects the plan from demand and process variability.
Inputs and operating assumptions
This model uses Units required per period (at least 0), Processing minutes per unit (at least 0), Productive hours per FTE (at least 0.01), Capacity buffer (at least 0), Current available FTE (at least 0). Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Required FTE = demand × minutes per unit ÷ 60 ÷ productive hours per FTE × buffer
What the calculator produces
The primary output is Required full-time capacity; it also exposes Required productive hours, Capacity gap, Base units per current FTE. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.

Frequently asked questions
What does the Capacity requirement do?
Convert unit demand and processing time into productive hours and required full-time capacity.
How does the Capacity requirement work?
The calculator applies Required FTE = demand × minutes per unit ÷ 60 ÷ productive hours per FTE × buffer. Productive hours should exclude leave, meetings, maintenance and ordinary downtime. A buffer protects the plan from demand and process variability.
What can I learn from the Capacity requirement?
It connects company inputs to a transparent business result. Change one value at a time to compare operating scenarios.
Does MW SysArc receive or store what I enter?
No. The calculation runs locally in your browser. MW SysArc does not receive or store your calculation inputs.
How should I use the result?
Use the result as a practical reference. Review the inputs, assumptions and stated limitations before relying on it.
