A new product can be priced right and still miss your budget

The proposed price is not a verdict

Every new listing arrives wearing a price, and the price is disarming precisely because it looks reasonable. It sits inside the range you already charge, so the eye accepts it. But a selling price is an input, not an answer. It only becomes a verdict after you take three things out of it: the tax the customer’s money isn’t really yours to keep, the cost of making or buying the thing, and any royalty or commission a third party skims off the top. What survives that subtraction is the product’s gross profit — and gross profit is the only quantity that can be compared to the budget you run the business on.

It’s worth being honest about the odds, because the trade repeats a scary one. You’ll often hear that 80% or even 95% of new products fail; that figure is a myth, traced back to nothing and kept alive by people with an interest in it sounding hard. When researchers actually counted, the failure rate for products that make it to launch settled at around 40%.[1] That’s the reassuring news and the sobering news in one number: most launches don’t fail, but two in five still do — and a good share of those die on economics that were knowable before a single unit was made. Taste and timing you can’t fully predict. Whether the margin clears your budget, you can.

Every business runs to a cost-of-sales budget — judge the newcomer against it

Ask an operator what margin a dish “should” make and you’ll get a number, because every business runs to one whether it’s written down or not. In UK hospitality the standard targets are well worn: food is usually costed to land around 28–32% of net sales, drink tighter at 18–24%, which is the same thing as a gross‑profit budget of roughly 68–72% on food and 76–82% on drink.[4] Whatever your own figure, that budget is the bar. A product isn’t “good margin” or “bad margin” in the abstract; it’s above your line or below it.

This is why a new product has to be judged against the budget, not against a gut sense of whether the price “feels dear.” The budget exists to protect a blended margin — the average across everything you sell that has to cover rent, wages and the light bill. Every line that sneaks in below budget quietly drags that average down, and it does so invisibly, because the till still rings. One under‑budget listing rarely announces itself; ten of them are why a busy site can turn over more and keep less.

Start from the margin, then read off the price

Here is the move most people do backwards. They pick a price that looks right and then check the margin, hoping it lands. Reverse it: start from the margin you need and let it tell you the price. That has an unfashionable name — cost‑plus, or target‑margin pricing — but survey after survey finds it’s how businesses actually price. In the euro‑area study of firms’ own reported behaviour, mark‑up‑over‑cost was the single most common method,[2] and the Bank of England’s survey of 654 UK companies found price‑setting predominantly cost‑based.[3] The market sets a ceiling you can’t sell above; your cost and your budget set a floor you can’t sell below and survive. Target‑margin pricing just makes you calculate the floor.

The arithmetic is one line. To hit your budget, the net price has to be the cost divided by the share of net revenue you’re allowed to spend on cost:

net price = cost ÷ (1 − gross‑profit budget), then add tax back on for the shelf price.

A £1.40 cost at a 65% gross‑profit budget needs a net price of £1.40 ÷ 0.35 = £4.00, which is £4.80 on the menu once 20% VAT goes back on. If a royalty or commission is in play, it simply joins the cost side of that fraction — the denominator becomes (1 − budget − rate), and the required price climbs to pay for the cut. That’s the whole of “how do I price it?”: not a hunch, a division.

Two listings, one budget

Put real numbers on it. Take a genuinely good product — costs £1.40, and the market will bear £5.40 on the shelf — with VAT at 20% and a 65% gross‑profit budget. On its own it clears the bar comfortably: £4.50 net, 31% cost, a 69% margin. Now add a routine 6% franchise royalty on net sales and watch a comfortable product slide under the line — and watch the two, and only two, ways back:

Same product, same budget. The royalty is treated as coming straight out of gross profit, the way a franchisee or platform seller actually feels it. On its own the product clears 65%, but a routine 6% royalty tips it under — and the only two ways back are a 40p price rise or a rate roughly a third lower. Those are the two levers, and a viability check hands you both numbers at once.

Notice what the headline price hid. At £5.40 the product looks well priced and comfortably profitable; it takes the royalty line to reveal it misses budget by two points. That’s not a rounding error — on a line doing hundreds of covers a period, two points of margin is real money leaking from a product everyone signed off as “fine.”

A 6% royalty is a nudge. A 30% commission is a different question.

The reason to compute the maximum rate a product can carry is that the cut varies wildly, and the arithmetic is unforgiving at the top end. A franchise royalty is typically 4–8% of sales;[6] a delivery platform is another order of magnitude. Uber Eats’ published UK rate is 30% of the order when it does the delivery, 13% when you deliver yourself;[5] across the main apps the full‑service figure sits around 25–35%. Drop a 30% commission into the same £5.40 product and it doesn’t need a 40p rise — it needs a different plan entirely.

Run it: £5.40 gross, less 90p VAT, less £1.40 cost, less £1.62 commission, leaves £1.48 — a 33% margin where you budgeted 65%. And here’s the part that stops a bad listing before it starts: at a 30% commission on the order value, with VAT taking another sixth, there is often no shelf price that clears a dine‑in gross‑profit budget at all. The tax, the commission and the margin you need can add up to more than the whole ticket before you’ve bought a single ingredient. That’s not a pricing failure, it’s the maths, and it’s exactly why delivery menus are priced up or run deliberately to a lower margin. A viability check tells you which world you’re in — “needs 40p” or “can’t work at any sane price” — in the time it takes to type the rate.

Three levers, and which one to pull

When a product misses budget there are exactly three things you can change, and it helps to know which is actually yours to move:

• The price. If you own it, target‑margin pricing gives you the number outright — then sanity‑check it against the market. If the market owns it (a platform, a keenly‑priced category), the price is a fact, not a lever, and you’re down to the other two.
• The cost. A cheaper spec, a better supplier price or a smaller portion moves the cost side of the fraction. It’s the slowest lever and the one most likely to change the product — useful, but rarely the thing you settle in the room.
• The rate. The royalty or commission is negotiable more often than people assume, and the maximum rate the product can carry at a sensible price is the single most useful number to walk into that conversation with. It turns “can you do better than 8%?” into “this line works at 5.5% and not above — here’s the arithmetic.”

Knowing the norms helps you know when to push. If a franchisor’s standard royalty already leaves you above budget, take the deal; if it doesn’t, you now know precisely how far it has to move. Same with a platform: if the product only clears budget at 13% and they’re quoting 30%, self‑delivery or a delivery‑specific price isn’t a preference, it’s the condition of the listing making money.

Gate on the percentage, size the prize in cash

One caution, because margin percentages can mislead in the other direction too. A product that beats budget but sells three a week matters less to the business than one that misses by a whisker and sells three hundred. So don’t stop at the percentage — run it through the forecast and read the cash. A point of margin on a high‑volume line is worth more than ten points on a curiosity.

That said, the percentage is still the right gate for a listing decision, precisely because it protects the blended margin every other product is helping to hold up. The discipline is to use both: let the budget percentage decide whether a line qualifies, and let the cash volume decide how much it matters — and if you do wave through something below budget, do it knowingly, because the volume earns its place, not because the price looked fine.

Before you say yes

Three habits turn this from a spreadsheet chore into a two‑minute reflex on every new listing:

• Price from the margin, not the gut. Compute the price your budget requires before you look at what “feels right.” If the market won’t bear that price, that is the answer — the product needs a cheaper spec or a lower rate, not a hopeful launch.
• Get the maximum rate before the meeting. Know the highest royalty or commission the product can carry at a sensible price, so you negotiate to a number instead of a vibe — and so you can spot instantly when a platform’s rate makes the listing impossible rather than merely tight.
• Gate on budget, size in cash. Let the percentage decide whether it qualifies and the forecast decide whether it matters. One under‑budget line dilutes the average that pays your bills; only wave it through when the volume genuinely earns the exception.

And keep one boundary clear: this is the economics gate, not the demand one. It tells you whether a product makes money if it sells — it says nothing about whether it will, or about what it might displace on the way. Whether the take‑up is genuinely new and what it quietly cannibalises from your existing range are their own questions, with their own articles. But those are the upside and the risk. The subtraction in this one is the floor — the part you can settle in advance, with the figures already in your costing sheet and the rate already on the table.
