Supermarket Replenishment Quantity with downstream consumption rate of 10 units/hr: a worked example

Suppose downstream consumption rate falls to 10 units/hr. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate supermarket replenishment quantity using consumption rate, replenishment cycle time, and a safety stock multiplier.

The inputs for this scenario

  • Downstream consumption rate: 10 units/hr (the input this scenario stresses; the baseline uses 20)
  • Replenishment loop cycle time: 4 hrs (held at the documented default)
  • Safety stock multiplier: 1.3 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Replenishment Qty = Consumption Rate x Cycle Time x Safety Multiplier.
  • Replenishment quantity (units) works out to 52 units at these inputs, and this is the headline figure for the scenario.
  • Base product works out to 52 value at these inputs.
  • Multiplier works out to 1 x at these inputs.
  • Factor A x B works out to 40 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where downstream consumption rate sits at 20 units/hr and the headline result is 104 units, this scenario comes in 50% below the baseline at 52 units.
  • It calculates the units a supermarket should hold by multiplying the consumption rate, the replenishment loop cycle time, and a safety stock multiplier. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Replenishment quantity (units): 52 units (headline result)
  • Base product: 52 value
  • Multiplier: 1 x
  • Factor A x B: 40 value
