The Core Formula
Recipe costing is straightforward in principle:
Recipe Cost = Σ (Ingredient Quantity Used × Current Price Per Unit)
Then to get food cost percentage:
Food Cost % = (Recipe Cost ÷ Menu Price) × 100
Industry target is typically 28–35% for food, lower for beverages. A dish selling for $22 with a $6.60 recipe cost sits at exactly 30% — healthy. The same dish after a supplier price increase that pushes recipe cost to $8.00 is suddenly at 36.4%, quietly eroding your margin on every cover.
The Fields That Matter
A complete recipe cost card should capture:
- Ingredient name and unit of measure (oz, lb, each, ml)
- Purchase price per unit from your most recent invoice
- Yield % — a 5 lb bag of onions doesn't yield 5 lb after trim; account for waste
- Portion quantity per serving
- Calculated cost per portion for each ingredient
- Total recipe cost and menu selling price
- Resulting food cost % and gross profit per cover
A Worked Example
Braised short rib, plated for one:
| Ingredient | Qty | Yield % | Unit Cost | Portion Cost | |---|---|---|---|---| | Short rib | 10 oz | 70% | $0.95/oz | $9.50 | | Demi-glace | 2 oz | 100% | $0.40/oz | $0.80 | | Potato purée | 5 oz | 90% | $0.12/oz | $0.60 | | Garnish/misc | — | — | — | $0.45 | | Total | | | | $11.35 |
At a $38 menu price, food cost is 29.9%. If short rib climbs to $1.15/oz, cost jumps to $13.28 and food cost hits 35% — time to reprice or reformulate.
Why Spreadsheets Break Down
Standalone recipe costing tools like those in some POS add-ons do this math well. The real problem is keeping ingredient prices current. Most operators update costs manually — quarterly at best — meaning their recipe cards are almost always stale.
How Hubstaurant Automates Recipe Costing
Hubstaurant reads your supplier invoices automatically and updates the price-per-ingredient in real time. Every recipe card connected to that ingredient reprices itself the moment a new invoice lands. You see margin drift the day it happens, not at month-end.
Because scheduling, POS analytics, and food-cost tracking live in the same system, you can cross-reference a dish's theoretical cost against actual usage from inventory — flagging discrepancies that signal waste or theft without logging into three separate platforms.
