Min/max inventory levels: Definition, Formula & Why It Matters

Also called: Min/max

Min/max inventory levels are a simple reorder rule: when stock falls to the minimum (your reorder point), you order back up to a set maximum. It gives clear guardrails for purchasing without complex forecasting.

Min/max inventory levels formula

Min = reorder point; Max = reorder point + order quantity; Order = Max − current stock

Example

With a min of 50 and a max of 150, hitting 50 units triggers an order of 100.

Why it matters for Reverb sellers

Min/max rules make restocking systematic, which matters when you manage many SKUs. They prevent both running dry and over-ordering, with almost no day-to-day decision-making.
