Production Capacity

Production capacity is the maximum output a plant, production line, machine, or team can produce in a given period with its existing resources. It equals available production time divided by cycle time per unit. For example, one machine that makes 20 units per hour over an 8-hour shift has a capacity of 160 units per shift.

Capacity sets the ceiling on what operations can deliver, so it feeds supply planning, sales and operations planning (S&OP), and capital expenditure decisions. Most plans use effective capacity, which accounts for planned downtime, maintenance, and changeovers. That makes it a more realistic input for capacity planning and FP&A forecasts.

Running above capacity requires extra shifts or overtime, which raises average costs, and sustained utilization above 90–95% wears equipment and reduces responsiveness. Low utilization spreads fixed costs over fewer units, which raises unit cost and cost of goods sold (COGS).
