One price changes.
Where does the review stop?
Change a supplier price to see the effect on three dishes, then explore the questions we would ask about the costing process.
Supplier update / Ready-to-use salmon
Original supplier price: €20 / kg
Extra weekly ingredient cost
At the sample sales volumes below.Where the change lands
Sample target: 55% food margin| Dish / weekly sales | Menu price | Food cost | Food margin | Status |
|---|---|---|---|---|
| Salmon bowl90 dishes / week | €18.00 | €8.52was €7.80 | 52.7%was 56.7% | Review |
| Crispy salmon bites70 dishes / week | €12.00 | €5.20was €4.80 | 56.7%was 60.0% | Within target |
| Grilled salmon60 dishes / week | €26.00 | €12.08was €11.20 | 53.5%was 56.9% | Review |
A price increase is the starting point. The next question is where the review process broke down.
What the diagnosis would examine
Review two dishes.
- PurchasingDid the new price reach the recipe costing sheet?
- ChefDo recorded quantities match the portions actually served?
- ManagerWho reviews margin changes, and what prompts that review?
The recommendation could be a clearer review routine, updated costing records or better use of existing tools. The diagnosis comes first.
What’s behind the numbers?
Food margin is (menu price − ingredient cost) ÷ menu price. All prices exclude VAT. This is the amount left after ingredients, before labour, rent and other costs; it is not net profit.
The sample recipes use 180 g, 100 g and 220 g of ready-to-use salmon. Other ingredient costs are €4.20, €2.80 and €6.80 per dish. Weekly sales stay at 90, 70 and 60 dishes. Only the salmon price changes.
The 55% target is an example setting for this demo. In a real business, targets and review responsibilities are agreed with the team.
