The most common food-cost mistake
The biggest mistake is reading plate-level ratios only and ignoring period-end inventory effects. That is how operations look healthy on paper but weak in cash performance.
Example 1: Plate-level food cost
- Selling price: 420
- Ingredient cost: 132
- Food cost: (132 / 420) x 100 = 31.4%
This may look healthy, but rising waste can still erode real margin.
Example 2: Period-level total food cost
- Beginning inventory: 480,000
- Purchases during period: 1,250,000
- Ending inventory: 390,000
- Cost of goods used: 1,340,000
If period food sales are 3,950,000, total food cost is 33.9%.
Example 3: Hotel outlet comparison
| Outlet | Sales | Food used | Food cost |
|---|---|---|---|
| Breakfast | 1,200,000 | 420,000 | 35.0% |
| Room service | 780,000 | 300,000 | 38.5% |
| Dinner restaurant | 1,970,000 | 620,000 | 31.5% |
In this case, room service is the first correction target.
Why prime cost must be included
Food cost alone is not enough for decision quality. It must be read with labor cost. If prime cost exceeds the 60-65% band, the model is under pressure.
Conclusion
Reliable food-cost control is a cadence, not a formula. Plate-level, period-level, and outlet-level tracking must run together.
