Why does usable capacity fall so far below gross?

Two losses apply in sequence. At the defaults, warehouse readiness removes 89.6 parts and handling yield removes another 123.65, so 906.75 of the 1,120 gross parts remain usable.

What is dealer warehouse readiness?

The share of stocked parts the warehouse can actually place in its storage locations. The rest sit in receiving, blocked or mislabeled, so they cannot be sold in the season.

Is a higher stocking yield always better?

Yes. Raising yield keeps more of what readiness placed, so usable capacity rises toward the gross total. It never lowers the usable count.

How should I set the stocking target?

From the seasonal sales plan for the parts family. If usable capacity lands below it, lift readiness or yield, or add cycles, rather than counting on parts that never reach the shelf.

Dealer Parts Stocking Capacity Calculator

Find how many parts a dealer can actually place on the shelf over a season, after losses to warehouse readiness and handling. The result is compared with the stocking target the network planned.

What this calculator does

Usable dealer parts stocking capacity from parts per cycle, cycles, warehouse readiness and handling yield, against a stocking target.

Formula used

Gross stocking capacity = parts per replenishment cycle × seasonal cycles
Lost to readiness = gross × (1 − readiness ÷ 100)
Lost to yield = gross × readiness ÷ 100 × (1 − yield ÷ 100)
Usable stocking capacity = gross − lost to readiness − lost to yield
Stocking variance versus target = usable capacity − target

Inputs explained

Parts per Replenishment Cycle: Parts the dealer stocks per cycle, from the order plan.
Seasonal Replenishment Cycles: Replenishment cycles in the selling season, from the dealer calendar.
Dealer Warehouse Readiness: Share of stock the warehouse can place, from the readiness audit.
Usable Stocking Yield: Share of stocked parts usable after handling, from cycle counts.
Target Stocking Capacity: Stocking target the dealer network plans, from the seasonal plan.

How to use the result

Best suited to sizing seasonal stock for a dealer network, finding where stocking capacity leaks.
The model treats each cycle as identical; peak cycles may stock more parts than the plan. Stock already on hand is not counted, only parts moved through the replenishment cycles.

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).
