How to price a cake: the honest UK guide for home bakers

If you've ever handed over a cake, taken £40 for it, and then worked out afterwards that you probably paid yourself £2.50 an hour for the privilege, this guide is for you.

Pricing is the single biggest thing home bakers get wrong. Not decorating, not piping, not buttercream consistency. Pricing. And the reason is simple: most of the "how to price a cake" advice online is either American (wrong currency, wrong tax rules, wrong costs) or written by someone who's never actually made a Number 3 smash cake at 11pm the night before a party.

So let's do this properly.

The rule nobody tells you

Your cake price needs to cover five things, not one:

1. Ingredients
2. Packaging and consumables
3. Electricity and gas
4. Your time
5. Overheads (insurance, website, subscriptions, mileage, a bit for the taxman)

If you're only costing ingredients, you're running a very expensive hobby. That's fine if you know that's what you're doing. It's not fine if you're trying to build a business.

Step one: cost your ingredients properly

This is where most bakers trip up straight out of the gate. You don't cost an ingredient by what the bag costs. You cost it by what you used.

Say a 1.5kg bag of self-raising flour is £1.20. Your recipe uses 400g. Your flour cost for that cake isn't £1.20, it's:

(400 ÷ 1500) × £1.20 = 32p

Do that for every ingredient. Every one. Eggs, butter, sugar, vanilla, food colouring, fondant, sprinkles, the lot. Yes, even the tiny pinch of salt. It adds up faster than you think, especially with decorations.

A few things bakers routinely forget to cost:

• Food colouring gel (a £4 pot, used sparingly, can still add 20-30p per cake)
• Vanilla extract (proper stuff is expensive)
• Edible glitter, sprinkles, wafer toppers (shockingly pricey per gram)
• Fondant and modelling paste (weigh what you used, not what you opened)
• Cake drums, dowels, cards (these are ingredients too, functionally)

Get in the habit of weighing leftover ingredients after a bake and working backwards. It's tedious once. After that, the numbers stay in your head.

Step two: add packaging

Packaging is where "£40 feels reasonable" quietly becomes "£40 is a loss." Count up:

• Cake box
• Cake board or drum
• Greaseproof paper or cellophane
• Ribbon
• Cake topper (if included)
• A thank-you card, if you do them
• Dowels and internal supports for tiered cakes

For a standard 8-inch buttercream cake in a proper box with a drum and a ribbon, you're easily looking at £3-£5 in packaging alone. For a tiered wedding cake, it can be £15-£20 before the cake itself enters the equation.

Step three: don't forget the oven

Nobody talks about this and it's daft because electricity in the UK isn't cheap.

A rough rule: a domestic fan oven uses around 2-2.5 kWh per hour. At a typical UK unit rate of about 27p per kWh (check your actual bill, tariffs vary), that's roughly 55-70p per hour of baking.

A celebration cake with three 8-inch sponges baked in batches, plus a mock-bake to warm the oven, can easily be 2 hours of oven time. That's £1.20-£1.50 in electricity alone. Add your mixer, hob for sugar syrups, fridge running harder because you've got buttercream chilling in it for two days - call it £2 per cake minimum.

If you're doing a big order and running the oven all day, track it honestly. It's genuinely one of your biggest hidden costs.

Step four: pay yourself

This is the hard one.

Write down what your time is worth per hour. Not what you think customers will pay. What it's worth. If you wouldn't clean someone's house for £8 an hour, don't decorate a cake for £8 an hour either.

National Living Wage in the UK is currently £12.21 an hour for over-21s (as of April 2025). That's the floor. You are a skilled person making a bespoke product. You should be charging more than that, not less.

A reasonable starting point for a home baker with a year or two of experience is £15-£20 an hour. Experienced bakers doing wedding and sculpted work should be charging £25-£35 an hour and often more.

Now the bit that'll sting: actually log your hours. A "simple" birthday cake is rarely under 4 hours once you count shopping, baking, cooling, crumb coat, chill, final coat, decoration, box-up, and cleanup. Often it's 6-8. A two-tier wedding cake with sugar flowers can be 15-20 hours easily.

4 hours at £18 = £72 for your time. On its own. Before ingredients. Before anything else.

That is why the cake you thought was worth £45 is actually worth £110.

Step five: overheads and the taxman

A slice off the top needs to go to things like:

• Public liability insurance (£50-£100/year typically)
• Your website, booking system or subscriptions (if you use BakeBase Standard, that's £50/month - £1.15 per cake if you do 40 a month)
• Food hygiene course renewals
• A portion of your kitchen costs (gas, water, cleaning)
• Petrol if you deliver
• And, critically, income tax and National Insurance

On the tax front, here's what matters in the UK right now:

• The trading allowance is £1,000 a year. If your gross income from baking is under that, you don't need to register with HMRC or file a return.
• If you earn over £1,000, you need to register for Self Assessment and file a tax return.
• From the 2027/28 tax year, the reporting threshold rises to £3,000 (the tax-free allowance is still £1,000 - you'll just report via a simpler online system between £1,000 and £3,000).

If you're earning above £1,000 and haven't registered, sort that out before it catches up with you. It always does.

A practical rule: set aside 20-25% of your profit in a separate account for tax. You'll thank yourself in January.

Putting it all together: a worked example

Let's price a two-layer 8-inch buttercream birthday cake with a drip, some piped rosettes, and a simple topper.

Now, some of you just winced. "I can't charge £141 for an 8-inch cake, nobody round here will pay that."

Two responses to that.

One: plenty of customers will pay that, and you're not the baker for the ones who won't. The baker charging £45 for that cake is burning out and will quit within 18 months. You are not competing with her. You're competing with proper cake businesses, and they charge what this cake is actually worth.

Two: if you genuinely can't get £141 in your local market, look at your costs honestly. Maybe your time estimate is off. Maybe you can streamline. Maybe your target market is wrong. But don't fix it by underpaying yourself. That's not a business, it's a slow-motion collapse.

The mistakes to avoid

1. Pricing by what your friends think is fair. Your friends don't run cake businesses and they're not your customers anyway.
2. Comparing to supermarket cakes. Tesco is not making you a custom Bluey cake with your child's name on it. Different product, different price.
3. Not charging for consultations and revisions. Endless WhatsApps back and forth about colour swatches is time. Charge for it, or set limits.
4. Deposits that are too small. A 50% non-refundable deposit protects you from last-minute cancellations. 25% doesn't.
5. Forgetting delivery. Petrol, time, and the risk of the cake sliding in the boot are not free. Charge mileage, properly.

Make it easier on yourself

Working all this out by hand for every enquiry is painful, which is why most bakers stop doing it and go back to guessing. That's the trap.

We built BakeBase partly because we watched too many talented bakers underprice themselves into giving up. The platform has a proper quote builder, tracks your ingredient costs and recipes, and lets you send a professional itemised quote in about 90 seconds. If you're on the waitlist, you'll be one of the first to use it.

In the meantime: price the cake. The whole cake. Not just the flour.

You're running a business. Act like one.
