Bakery Costing: What a Costing App Must Get Right
Most bakery costings are wrong in the same five ways, and none of them are arithmetic errors. This covers pack-size conversion, yield loss, labour, overheads and the hidden consumables — and what to test before trusting any costing tool.
The five errors
Any one of these is survivable. Together they routinely make a product that looks 70% gross margin actually break even.
Pack-size conversion is the foundation
The single most useful thing a costing tool does is convert what you buy into what you use. You buy a 16 kg sack of flour for £18.40 and use 340 g. That is £0.391 — and doing that conversion by hand for twelve ingredients across thirty products is where errors and, more importantly, staleness enter.
Staleness is the bigger issue. A costing built by hand reflects prices on the day you built it. Ingredient prices move constantly, and a costing that is not repriced is a historical document. The free recipe cost calculator does the conversion; software does it and keeps doing it.
Yield, waste and what is actually sellable
A recipe makes a quantity of batter. It does not make that quantity of sellable product. Between the two sit evaporation in the oven, trim, the end pieces nobody buys, and breakages.
- Baking loss — commonly 8–12% for sponges, more for anything baked long and thin
- Trim — levelling and edging a tray, often another 5–10%
- Quality rejects — 2–5% in most hand operations
Cost per sellable unit is total batch cost divided by units you can actually sell, not units the maths says you made.
Pricing from a costing
Once cost per unit is right, the sell price follows from a target food-cost percentage. For baked goods sold direct, ingredient cost commonly lands between 15% and 30% of price — low, because labour dominates. Wholesale roughly doubles that percentage, which is why wholesale only works on volume and efficiency.
Our guide to pricing cakes for profit works through the method, and food cost percentage covers the targets.
What to test in a costing app
- Enter a 16 kg sack and use 340 g. Does it convert without you calculating?
- Build a sub-recipe, use it in two products, change it. Do both update?
- Set a waste percentage. Does cost per unit account for it?
- Change a supplier price. Does it tell you which products moved?
- Add labour and overheads. Are they in the unit cost or bolted on afterwards?
Frequently asked questions
How do I calculate bakery profit? Sell price minus true unit cost, where true unit cost includes ingredients at real pack prices, labour, consumables, overheads and yield loss. Most bakeries stop at ingredients.
What food cost percentage should a bakery aim for? 15–30% of sell price for direct retail. Consistently above 35% on direct sales usually means underpricing rather than expensive ingredients.
