Seasonal Demand Capacity Calculator
Find how many machines a seasonal build plan can actually deliver after downtime and first-pass yield losses. The result is compared with the output the sales plan needs.
What this calculator does
- Usable seasonal machine capacity from machines per cycle, build cycles, uptime and first-pass yield, against a seasonal target.
Formula used
- Gross seasonal capacity = machines per production cycle × seasonal build cycles
- Lost to downtime = gross × (1 − uptime ÷ 100)
- Lost to yield = gross × uptime ÷ 100 × (1 − first-pass yield ÷ 100)
- Usable seasonal capacity = gross − lost to downtime − lost to yield
- Seasonal variance versus target = usable capacity − target
Inputs explained
- Machines per Production Cycle: Machines completed per build cycle, from the build schedule.
- Seasonal Build Cycles: Build cycles available in the season, from the production calendar.
- Production Uptime: Share of scheduled time the line runs, from the uptime log.
- First-Pass Production Yield: Share of machines passing first time, from the build records.
- Target Seasonal Output: Seasonal output the sales plan needs, from the order book.
How to use the result
- Best suited to checking capacity before a seasonal commitment, deciding whether to add a build cycle.
- The model stops at the plant gate; transport, dealer preparation and field issues are outside it. Demand beyond the seasonal window is not leveled; capacity is measured inside the season only.
Current U.S. benchmarks
- Industrial natural gas averages $4.58 per Mcf (EIA, Jul 2026), down 1.3% from a year earlier, with industrial electricity at 9.77 cents per kWh. Process heating and refrigeration budgets track both.
- Steel mill PPI stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. New factory orders are up 8.5% year over year (Census).
- The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
Common questions
- Why is usable capacity below gross capacity? Downtime removes 129.36 machines and first-pass yield removes another 55.62 at the defaults, leaving 739.02 usable of 924 gross machines.
- What counts as production uptime? The share of scheduled build time the line actually ran. Planned maintenance and breaks are outside it; unplanned stops, shortages and breakdowns are inside it.
- How do I raise usable seasonal capacity? Add build cycles, lift uptime or improve first-pass yield. Each acts on a different loss row, so attack the largest lost row first.
- Does this replace a capacity plan? No. It sizes one line for one season. A full plan also covers labor, materials, tooling, storage and the dealer delivery schedule.
