Inventory variance
The difference between what your system says you should have in stock (theoretical) and what you actually counted (physical). Variance is the single best leading indicator of waste, theft, miscounted receiving or wrong recipes.
Deep dive: inventory variance
Variance is the difference between what a recipe says should have been used and what stock actually shows was used. On its own a single day's variance is noise — a scale rounding, a mis-keyed unit — but a variance line held per ingredient per outlet over a week is the closest thing an F&B operator has to an internal audit.
Read it by pattern rather than by size. Variance that appears on one ingredient across every outlet is usually a recipe that no longer matches the kitchen, or a supplier whose pack weight changed. Variance on one outlet across many ingredients points at receiving or at stock-count discipline. Variance that only appears on one shift, on high-value proteins, and disappears when a manager is on the floor, is a shrinkage conversation. LOOP flags any ingredient whose 7-day variance exceeds its threshold and names the outlet, the shift and the dishes that consumed it.
Formula
Variance % = (actual usage − theoretical usage) ÷ theoretical usage × 100
Worked example
Recipes for the week called for 62.0 kg of beef; stock movement shows 68.4 kg consumed → variance +10.3%.
At 285,000₫/kg that is 1,824,000₫ in one week at one outlet. A 3% tolerance would have been 530,000₫, so roughly 1,290,000₫ is recoverable through portion control or receiving checks.
What is Inventory variance used for in F&B operations?
In multi-outlet restaurant and F&B operations, inventory variance is an essential component — directly affecting service speed, order accuracy and margin. See the related terms below to understand where it fits in the broader stack.
How does LOOP support Inventory variance?
LOOP supports inventory variance natively in its POS + KDS + inventory platform for Vietnamese F&B chains — no plugin or third-party integration required. It's one reason multi-outlet operators pick LOOP as their primary operations system.
