Most breakfast spots guess their bread costs and wonder why profits disappear. Purchased bread isn't calculated like homemade items – you're working with per-piece pricing plus waste factors. Skip the guesswork and you'll know exactly where your money goes.
Calculate cost price for purchased bread
Purchased bread works differently than scratch-made items. You're not adding up flour and yeast – you start with the purchase price per piece, then add everything you serve alongside it.
? Example croissant:
You buy croissants for €0.85 per piece and serve them with jam and butter.
- Croissant: €0.85
- Butter (10g): €0.12
- Jam (15g): €0.08
- Plate and cutlery: €0.05
Total cost price: €1.10
Account for waste and packaging loss
Here's what most places miss: not every croissant makes it to a customer. Damage during transport, items going stale, storage mishaps – it all adds up to 3-8% waste that you need to factor in.
⚠️ Note:
Add waste to your cost price. If 5% of your croissants don't sell, each sold croissant costs €0.85 / 0.95 = €0.89 instead of €0.85.
Different purchase formats
Bread arrives in various formats, and each needs its own calculation approach. Here's how to handle them:
- Per piece: Direct cost price, add waste
- Per kilo: Divide kilo price by number of pieces per kilo
- Frozen (to be baked): Add baking costs (energy + time)
- Pre-baked: Only include reheating costs
? Example per kilo:
You buy rolls for €4.20 per kilo. There are 8 rolls per kilo.
- Cost price per roll: €4.20 / 8 = €0.53
- With 5% waste: €0.53 / 0.95 = €0.56
- Plus butter and toppings: €0.25
Total cost price: €0.81
Include additional costs
The hidden costs will surprise you if you're not tracking them. Don't forget these in your calculations:
- Energy: For baking or reheating
- Packaging: Bags, napkins, cutlery
- Additions: Butter, jam, cheese, cold cuts
- Labor: Time for baking and plating
Calculate food cost percentage
Breakfast typically runs 25-35% food cost – a pattern we see repeatedly in restaurant financials. Use this formula to check where you stand:
Food cost % = (Cost price / Selling price excl. VAT) × 100
? Example food cost:
You sell a croissant with jam for €3.50 incl. 9% VAT.
- Selling price excl. VAT: €3.50 / 1.09 = €3.21
- Cost price: €1.10
- Food cost: (€1.10 / €3.21) × 100 = 34.3%
This falls within the normal range for breakfast.
Shelf life and inventory
Fresh bread doesn't wait around. Plan your orders based on actual sales data, not hope. Running out beats throwing away every single time.
⚠️ Note:
Bread you throw away costs you the full purchase price. With 10% waste, your actual cost price increases by 11%. Plan conservatively.

How do you calculate the cost price of purchased bread? (step by step)
Determine the base purchase price
Note what you pay per piece or per kilo. When purchasing per kilo: divide by the number of pieces per kilo to get the price per piece.
Account for waste and loss
Add 3-8% waste to your cost price. Divide your purchase price by (100% - waste%). With 5% waste: divide by 0.95.
Add all additions
Add the costs of butter, jam, toppings, packaging, and any baking costs. This is your total cost price per portion.
Calculate your food cost percentage
Divide your cost price by your selling price excl. VAT and multiply by 100. Aim for 25-35% for breakfast products.
✨ Pro tip
Track your actual waste percentage for 2 weeks on croissants and bread rolls specifically. Most breakfast spots underestimate this by 3-5%, which directly inflates their real food costs.
