Most sandwich shop owners guess their baguette costs - and that's why they're losing money on every sale. I've seen countless shops estimate ingredient costs, only to discover they're actually losing €0.50-€1.20 per baguette. Here's how to calculate your exact cost price and stop the bleeding.
Inventory all ingredients
For an accurate cost price calculation, you need to literally count everything that goes on the baguette. Even the smallest ingredients like butter, salt, or herbs add up to your final cost.
💡 Example: Ham and cheese baguette
- Baguette: €0.65
- Ham (80g): €1.20
- Cheese (40g): €0.85
- Butter (10g): €0.08
- Lettuce (15g): €0.12
- Tomato (30g): €0.18
Total cost price: €3.08
Don't skip the 'invisible' ingredients like:
- Butter to spread on the bread
- Herbs and spices
- Sauces (mayonnaise, mustard)
- Packaging materials (bag, napkin)
Convert purchase prices to portions
You buy ingredients per kilo or per package, but only use a portion per baguette. Converting to grams is essential for an accurate cost price.
💡 Example: Converting ham
You buy ham for €15.00 per kilo and use 80 grams per baguette:
€15.00 ÷ 1000 grams × 80 grams = €1.20 per portion
For an accurate calculation you need:
- Purchase price per kilo or per piece
- Weight you use per baguette
- Kitchen scale for consistent portions
⚠️ Watch out:
Check your portions regularly. Many staff members give larger portions than planned, which increases your cost price without you noticing.
Include waste and loss
Not all ingredients you buy end up on baguettes. This is a mistake that costs the average restaurant EUR 200-400 per month - waste from spoilage, cutting loss, and leftovers increases your actual cost price significantly.
Common waste percentages in sandwich shops:
- Bread: 5-10% (unsold at closing time)
- Cold cuts: 3-8% (last slices, spoilage)
- Vegetables: 10-20% (wilted lettuce, overripe tomatoes)
- Cheese: 2-5% (rind, drying out)
💡 Example: Cost price with waste
Basic baguette costs: €3.08
Waste percentage: 8%
Actual cost price: €3.08 × 1.08 = €3.33
Calculate food cost percentage
Once you know the total cost price, you can calculate what percentage of your selling price goes to ingredients. For sandwich shops, a healthy food cost sits between 25% and 35%.
The formula: Food cost % = (Cost price ÷ Selling price excl. VAT) × 100
💡 Example: Food cost calculation
Cost price: €3.33
Selling price: €7.50 incl. VAT → €6.88 excl. VAT
Food cost: (€3.33 ÷ €6.88) × 100 = 48%
This is too high! You're not earning enough on this baguette.
⚠️ Watch out:
Always calculate with the price excluding VAT. The price on your menu includes 9% VAT. Divide by 1.09 to get the price excl. VAT.
Digital tools for cost price calculation
Manual calculations take time and create errors. Many sandwich shops use digital tools to automatically calculate cost prices and track changes when suppliers adjust their prices.
Benefits of digital cost price calculation:
- Automatic recalculation when prices change
- Overview of all baguettes in one system
- Direct food cost percentages per product
- Alerts when cost prices climb too high
How do you calculate the cost price of a filled baguette?
Make an ingredients list
Write down all ingredients that go on the baguette, including butter, herbs, and packaging. Weigh each portion you use and note the weight in grams.
Calculate costs per ingredient
Divide the purchase price per kilo by 1000 and multiply by the number of grams you use. For example: €15/kg ham ÷ 1000 × 80g = €1.20 per portion.
Add everything up and include waste
Sum all ingredient costs for the base cost price. Increase this by 5-10% for waste and loss. This gives you the actual cost price per baguette.
