Replenishment Cycle
The expected interval between consumable or replacement-part purchases.
Definition
A replenishment cycle is the expected time between needs for a consumable or wear item—such as a water filter cartridge or vacuum bag. Cycles vary by usage, product type, and environment.
Merchants should treat published intervals as estimates unless they have a defensible measurement basis. Reminder programs should remain optional and accurate.
Key points
- Usage-dependent; averages can mislead individual customers.
- Inventory planning may use cycles differently from marketing reminders.
- Overstated certainty damages trust.
- Label published intervals as estimates unless measurement supports them.
