To price a cake in the UK, add up your ingredient costs, add your overheads (energy, packaging, equipment wear), multiply your labour hours by an hourly rate you actually want to earn, then add a profit margin. A simple working formula is:
(Ingredients + Overheads + Labour) × 1.25 (or more) = Your Price
That 25% on top is your profit — not your wage. Your wage is already inside the labour figure. Most UK home bakers undercharge because they only count flour and eggs, forget their time entirely, and then wonder why they're exhausted and broke. Let's fix that properly.
Don't guess. Work out the cost of the amount you actually use, not the price of the whole bag.
For example, if a 1.5kg bag of caster sugar costs £1.50, that's £1 per kg, or £0.001 per gram. A recipe using 400g of sugar costs you 40p. Do this for every single ingredient — flour, butter, eggs, vanilla, food colouring, fondant, ganache, the lot.
A typical 8-inch two-layer vanilla sponge with buttercream might cost £4–£7 in ingredients. A heavily decorated celebration cake with fondant, fresh flowers, and gold leaf can easily hit £15–£25 in materials alone.
Don't forget the small stuff:
Tracking this by hand is tedious, which is exactly why so many bakers skip it — and lose money.
These are the costs that don't appear in the recipe but are very real.
Energy: Ovens are expensive to run. A typical electric oven uses roughly 2–2.2 kWh per hour. At around 25–28p per kWh (2024 UK average), an hour of baking costs roughly 50–60p — and that's before the mixer, fridge, and lighting. A cake needing 1.5 hours of baking plus prep could easily use £1–£1.50 in electricity.
Equipment depreciation: Your stand mixer, tins, turntables, and piping nozzles wear out. Add a small amount — even 50p–£1 per cake — to build a fund for replacements.
Other costs: Insurance (you should have it), your food hygiene certificate, website or social media costs, and mileage if you deliver.
A safe overhead estimate for a home baker is £2–£4 per cake, scaling up for larger or more complex bakes.
This is the step that separates a hobby from a business. Your time has value. Decide on an hourly rate — and please don't say minimum wage. You're a skilled maker. £12–£20 per hour is a fair and common range for UK home bakers, depending on your skill level and area.
Now be honest about how long a cake really takes:
A "simple" buttercream celebration cake often takes 3–4 hours of actual work. At £15/hour, that's £45–£60 in labour alone. A detailed two-tier wedding cake can take 8–12 hours.
If that number shocks you, that's the problem — most home bakers have been giving their labour away for free.
Labour pays you. Profit pays the business — it covers quiet months, lets you invest in better tools, and gives you breathing room. Add 20–30% on top of your total costs.
Let's price a single-tier, 8-inch buttercream birthday cake serving 20:
| Item | Cost |
|---|---|
| Ingredients | £6.00 |
| Overheads (energy, board, box, depreciation) | £3.50 |
| Labour (3.5 hrs × £15) | £52.50 |
| Subtotal | £62.00 |
| Profit margin (25%) | £15.50 |
| Final price | £77.50 |
You'd likely round this to £75–£80. If that feels high, remember: a high-street bakery would charge similar or more, and you're making it fresh, custom, and by hand.
Price per serving is a useful reality check. Divide your total by the number of slices.
If your calculated price falls far outside these, recheck your figures.
If you're selling cakes from home in the UK, you must register with your local council as a food business (it's free, do it at least 28 days before you start). You'll also want public and product liability insurance, and ideally a Level 2 Food Hygiene certificate. These costs belong in your overheads.
Pricing a cake isn't about picking a number that "feels right" — it's about adding up real costs, valuing your time properly, and building in profit. Once you've costed a few cakes this way, you'll spot exactly where your money leaks: the underpriced labour, the ingredient creep, the delivery you never charged for.
The hard part is doing this maths consistently for every recipe, every time ingredient prices change. If you'd rather your recipes cost themselves — pulling ingredient prices, calculating yields, working out cost per portion, and scaling batches automatically — PrepSheet does exactly that.
