Replenishment Rate
Definition
Replenishment rate is the percentage of customers who reorder a consumable product within its expected use cycle (e.g., a 30-day supply being reordered by day 45). Different from repeat purchase rate, which is any second order regardless of timing or product.
How operators actually use it
For replenishment-driven categories (coffee, supplements, pet food, beauty), replenishment rate is the strongest single signal of product-market fit. A 50%+ 60-day replenishment rate on a 30-day-supply product means the product is doing its job. Operators use replenishment timing to trigger automated SMS or email reminders 5-7 days before expected reorder, lifting the rate 10-15 points typically.
Common pitfalls and honest-cost notes
Reordering at the wrong size (customer buys 90-day supply when they used 30 days) confuses the metric. Track replenishment in unit-days consumed, not order count. Also: brands often celebrate high replenishment from heavy users while masking that 60% of customers never reorder at all. Segment your replenishment metric by usage-tier customer to find where the leak is.
