Case Pack / Inner Pack Calculator

Calculate order quantities, days of supply, reorder points, and shelf facings from case pack and movement data.

Case Pack / Inner Pack Calculator

Enter case pack quantity, shelf capacity, average daily movement, current on-hand, lead time, and target days of supply to calculate how many cases to order, when to reorder, and how long your stock will last. Optional shelf and unit dimensions compute facings, layers, and depth for planogram planning. A sawtooth inventory chart shows stock depletion and replenishment over time. Runs entirely in your browser — your data never leaves your machine.

What Is a Case Pack?

A case pack is the number of individual selling units packed in a single shipping case. Many products also have an inner pack — a smaller grouping inside the case (e.g., a case of 24 contains 4 inner packs of 6). Understanding the case pack structure is essential for ordering the right quantity: you can only order in full cases, so the actual units received are always a multiple of the case pack quantity.

Days of Supply and Reorder Points

Days of supply tells you how long your current inventory will last at the average daily selling rate. The reorder point is the stock level at which you need to place an order so that the delivery arrives before you run out, accounting for lead time. This calculator combines both metrics with the case-pack constraint to tell you exactly how many cases to order and when.

Automating Replenishment

This calculator handles individual item planning. For automated replenishment across a full assortment, I build ordering and inventory integrations that connect POS movement data with warehouse and vendor systems. See grocery and retail services or explore integration services. Also see the EOQ Calculator, Reorder Point Dashboard, and Safety Stock Calculator for related inventory planning tools.
