How to Calculate Menu Costing (Step-by-Step for Profit)

Menu costing is the process of converting your recipe into numbers:
  • how much it costs to make each dish (ingredient cost per dish)
  • what food cost % you are running
  • what selling price you need to hit profit targets

This guide explains how to calculate menu costing in a way that you can repeat when ingredients change.

Step 1: Build recipe cards + standard portions

For each menu item, create:
  • ingredient list
  • quantity used per dish (grams/ml/pieces)
  • standard yield (how much becomes the final usable portion)

Without standard portions, menu costing becomes guesswork.

Step 2: Convert ingredient unit prices

From invoices, get:
  • price per kg/litre/piece
  • unit conversion (e.g., 1 kg = 1000 g)

Your goal: make every ingredient cost “per unit you use in the recipe”.

Step 3: Calculate ingredient cost per dish

Use: 
Ingredient cost per dish = (Quantity used per dish / Purchase unit quantity)  Purchase price

Repeat for each ingredient and sum them.

Step 4: Add yield and wastage logic

Yield/wastage affects dish cost.

Common approaches:

  • Include wastage directly in the quantity used (simpler if your kitchen already tracks it)
  • Or apply a yield factor at the end (if yield changes but recipes remain stable)

Pick one approach and stick to it.

Step 5: Compute total food cost per dish

Total food cost is the sum of all ingredient costs for the dish: 
Total food cost per dish = sum(all ingredient cost per dish)

Step 6: Calculate food cost % and validate

Once you have food cost per dish, compute: 
Food cost % = (Food cost per dish / Selling price)  100

Validate by comparing:

  • food cost % trend over time
  • differences between categories (sandwiches vs beverages may differ)
  • outliers (items with unusually high food cost %)

Step 7: Set prices and update your QR menu

After costing, price your menu to hit your target contribution margin.

Then update pricing in your QR menu system so customers see correct prices and availability.

Common mistakes

Avoid:
  1. Using approximate serving weights
  2. Ignoring yield/wastage
  3. Not updating unit prices from purchase invoices
  4. Mixing delivery portion assumptions with dine-in
  5. Pricing a menu without checking the food cost % against targets

FAQs

1. Is menu costing only for fine dining?

No. Any restaurant with a multi-item menu needs repeatable costing, even small cafes.

2. Do I need a spreadsheet?

A spreadsheet is perfect to start, then you can move to tools once consistent.

3. How often should I update menu costing?

Monthly minimum, and immediately if ingredient prices change materially.

4. What if my menu has combos?

Cost combo items by summing costs of included dishes and applying yield where needed.

5. Can QR menus help costing accuracy?

They help with speed and accuracy of pricing/availability updates after costing changes.
