A store can be full and still under-earn when menu costs are updated too slowly. The fix is not more reporting. The fix is faster item-level decisions.
1) Context: Why Operators Search for “Menu Costing App”
The usual trigger is operational overload:
- ingredient prices changed, but menu prices did not
- recipe files are spread across multiple sheets
- owners cannot tell which items are actually carrying margin
A menu costing app is valuable only if it shortens the path from price change to menu action.
2) Table: Evaluation Criteria Before You Adopt
| Capability | Minimum standard | Failure mode if missing |
|---|---|---|
| Unit normalization | Case -> lb/oz/each conversion in-app | Inconsistent cost base |
| Yield/loss support | Ingredient-level usable quantity | Chronic undercosting |
| Sub-recipe rollups | Parent items auto-update | Hidden margin drift |
| Channel-aware costing | Dine-in vs pickup vs delivery inputs | Wrong channel pricing |
| Fast repricing output | Required price from margin targets | Slow decision cycles |
Do not buy features you will not operate weekly.
3) Formula: Menu Costing Decision Stack
plateCost = sum(ingredientCost per serving)
foodCostPercent = plateCost / menuPrice
contributionPerItem = menuPrice - plateCost - channelVariableCostsRequired price by target:
requiredMenuPrice = (plateCost + channelVariableCosts) / (1 - targetContributionMargin)This formula is where an app should save time versus spreadsheet work.
4) Worked Example: Three Items, One Repricing Decision
Assumptions include channel-variable costs for delivery-heavy mix.
| Item | Current price | Plate cost | Channel variable cost | Contribution | Contribution margin |
|---|---|---|---|---|---|
| Bowl A | $12.50 | $4.10 | $1.90 | $6.50 | 52.0% |
| Wrap B | $10.99 | $3.95 | $1.80 | $5.24 | 47.7% |
| Salad C | $11.49 | $4.85 | $2.10 | $4.54 | 39.5% |
If target contribution margin is 45%, Salad C is below floor and should be repriced or redesigned first.
Required price for Salad C:
requiredMenuPrice = (4.85 + 2.10) / (1 - 0.45)
= 6.95 / 0.55
= $12.645) Interpretation: Prioritize by Money, Not by Volume
| Pattern | What it means | Priority action |
|---|---|---|
| High-volume, low-margin item | Major cash leak | Reprice first |
| Low-volume, low-margin item | Limited impact | Defer or remove |
| High-margin, low-volume item | Upsell opportunity | Improve placement |
| Stable margin, high complexity | Process risk | Standardize prep and portions |
Use retained-dollar impact to set weekly workload.
6) Action: 30-60-90 App Adoption Plan
- Days 1-30: Migrate top 20 ingredients and top 10 SKUs.
- Days 31-60: Add sub-recipes and channel-variable cost layers.
- Days 61-90: Move to weekly recost and biweekly repricing cadence.
- Lock one owner review meeting per week (30 minutes).
- Report only three numbers: effective take rate, contribution per order, bottom-5 item leakage.
7) Operator KPI Set
minutes to recost top 10 itemsbottom-5 item contribution dollarspercent of sales from above-target items
If these improve, the app is working.
