What is Food-cost variance?
Food-cost variance is the daily delta between theoretical COGS (sales × recipe cost) and actual COGS (opening + purchases − closing stock). Chains without recipe-level inventory commonly run ±5–8%; with it, ±2% within 90 days is a realistic target (illustrative estimate, not measured data). The single most actionable F&B P&L metric.
Formula
Variance % = (Actual COGS − Theoretical COGS) / Net Sales × 100. Healthy band: ±2% on recipe-level inventory; ±5–8% without.
Worked example
A 6-outlet QSR chain runs at +6.4% food-cost variance in Q1 2026. Recipe-level deduction + LOOP anomaly alerts compress it to +1.9% by month 4, a ₫340M annualised margin recovery on ₫22Bn revenue.
Food-cost variance in day-to-day operations
Operators meet food-cost variance at three moments: when a system is first configured, when a second outlet opens, and when margin is reviewed. At each point the practical question is not the definition but who owns it, where the data lives, and how quickly a discrepancy surfaces.
If food-cost variance lives only in a spreadsheet or in a manager's head, it drifts. When it sits in the operating system alongside tickets, recipes, payments and delivery commission, a discrepancy shows up the next morning instead of at month end, and that gap is where the money is.
LOOP handles food-cost variance inside the same POS, KDS and inventory platform, running on devices you already own rather than dedicated hardware. Browse the full F&B glossary or see LOOP pricing.
What is Food-cost variance used for in F&B operations?
In multi-outlet restaurant and F&B operations, food-cost 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 Food-cost variance?
LOOP supports food-cost 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.
