Weekly Capacity Calculator
Use this calculator when sales, planning, or operations needs a weekly capacity number for a line or value stream. It converts planned daily capacity into good weekly output after normal losses.
What this calculator does
- Calculate good units per week from daily output assumptions, production days, uptime, and yield.
- a planner needs to compare weekly demand with realistic production line capacity
- The result estimates good units the line can produce over the planned week.
Formula used
- Gross weekly capacity = planned daily output × production days
- Good weekly capacity = gross weekly capacity × uptime × yield
Inputs explained
- Planned daily line output: Use gross planned daily output before weekly uptime and yield losses.
- Production days per week: Include scheduled production days, not calendar days.
- Expected weekly uptime: Account for planned maintenance, meetings, and recurring downtime.
- Expected weekly good yield: Use expected good units after rejects and rework holds.
How to use the result
- Use it for S&OP, weekly scheduling, demand commits, and labor or overtime reviews.
- It does not model product mix sequence, material shortages, or changeover calendars unless reflected in the inputs.
Common questions
- What is Weekly Capacity for? Calculate good units per week from daily output assumptions, production days, uptime, and yield.
- What information do I need before using it? You need planned daily line output, production days per week, weekly uptime, and expected good yield.
- When is the result only an estimate? The result is approximate when the week includes unusual product mix, planned shutdowns, or unstable staffing.
- How can I use the result on the line? Use weekly capacity to compare against booked demand and decide whether to add shifts, pull ahead, or protect bottleneck time.
