How do you calculate weekly production capacity?

Multiply planned daily output by production days per week for gross capacity, then multiply by uptime and yield. At 5200 units/day over 5 days with 89% uptime and 97% yield, good weekly capacity is 22,445.8 units/week.

Why plan at the weekly level instead of daily?

Because customer commitments, S&OP and overtime decisions are usually weekly. Aggregating shows the compounding cost of losses: here downtime removes 2860 units and rejects remove 694.2 units from a 26,000-unit gross week.

What is a good weekly uptime?

For a steady five-day operation, 87-92% weekly uptime is typical and the 89% default sits right in that band. Mondays after a shutdown often run lower, so the weekly average matters more than any single day.

How many production days should I use?

Use only days the line is actually scheduled to run, not calendar days. Five is standard for a single-weekend-off operation; enter six or seven if you run weekends, and the gross and good figures scale directly.

How much capacity do I lose to downtime each week?

In this example, 2860 units/week vanish to downtime versus 694.2 to rejects. That ratio tells you reliability improvements would add roughly four times more weekly output than equivalent yield improvements.

When do I need overtime or an extra shift?

When the order book exceeds good weekly capacity. If demand tops 22,445.8 units/week here, you must add production days, lift uptime, or schedule overtime rather than assume the gross 26,000 is achievable.

Weekly Capacity Calculator

Weekly capacity rolls a line's planned daily output and number of production days into the good units it can ship across a full week. Plant managers and S&OP planners use it to commit weekly volumes, compare capacity against the order book, and plan overtime or extra shifts before a shortfall appears. The metric matters because weekly commitments aggregate every daily loss: a few points of downtime and scrap compound into thousands of missing units by Friday. Planning to gross weekly numbers is how backorders accumulate.

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
It computes good units per week from planned daily output times production days, derated by weekly uptime and good yield.

Formula used

Gross weekly capacity = planned daily output × production days
Good weekly capacity = gross weekly capacity × uptime × yield

Inputs explained

Planned daily line output:
Production days per week:
Expected weekly uptime:
Expected weekly good yield:

How to use the result

Use it for weekly production planning, comparing capacity to the order book, or deciding whether overtime or an added shift is needed.
It applies one average uptime and yield to the whole week; a bad day, a startup after a weekend shutdown, or a quality excursion can pull a given week below the calculated figure.

Current U.S. benchmarks

The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
