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.
