How much should I charge? Price from the batch

The question small food businesses actually ask each other is not “what is my food cost %”. It is what do I put on the sticker: a tray of sausage rolls, a jar of jam, a grazing box, a loaf, a market-stall brownie. The answers that come back cluster into four folk rules. Three of them fail for the same reason: they never look at what this batch actually cost.

This is the price half. The cost half — why last month’s pack price quietly eats the margin — is our guide on costing a recipe when ingredient prices keep moving.

The four folk answers

1. “3× ingredients”

The old caterer’s heuristic: add up the shopping list and charge three times that. Some people meet it as the 3-2-1 rule. Pricing guides in 2025 still have to explain it, in order to say stop using it.

It fails because the shopping list is not the cost. Time is. Filling a hundred small jars, assembling a grazing box, or decorating a celebration order can take hours against a modest ingredient bill. Packaging, energy and waste never appear on that list either. Multiplying ingredients by three prices the mix and gives the making away.

2. Copy the neighbour

Look at Facebook or Instagram, find a similar product, charge the same. It feels like market research.

It fails because the neighbour is often asking the same question. FoodCore’s UK guide (15 June 2026) says this out loud: market rate is a sense-check, not a substitute for cost. Two businesses matching each other can both be losing money, especially if neither of them is costing from the pack they actually used this week.

3. Food cost 25–35% of selling price

A hospitality target (the kind of number Toast, KORONA and UpMenu publish for restaurants): ingredient cost should be a quarter to a third of the sticker, so ingredient ÷ 0.30 is treated as the minimum price.

It fails because it is a floor on ingredients only. Nobody has been paid, and a box, a jar or a label has not gone on. For a small producer the making is often the larger share; a restaurant percentage does not travel.

4. (Ingredients + labour + overhead) ÷ (1 − target margin)

The formula every pricing calculator now ships. Rearranged: if you want a 50% margin, divide the full cost by 0.5; if you want 40%, divide by 0.6. The literature quotes wide target ranges depending on whether you sell from home, do custom work, or sell wholesale — and those are their numbers, not ours.

This one is the right shape. The fight is over whether the three inputs are real. People know ingredients, guess time, invent an hourly rate, skip overhead, then undercut because the resulting number “looks high”. Wholesale versus retail is a second question the same threads spawn; it does not get easier if the cost underneath is a guess.

What actually belongs on the sticker

Start from the batch, not from Instagram.

1. A real pack cost, not a remembered one. The cost of what you made has to trace back to the supplier pack you used: what you were charged for that butter, that mince, that sugar, that jar, on that delivery. A typed estimate of what you usually pay is the same failure as last month’s price left sitting in a spreadsheet. Our costing guide is this step.
2. Packaging in the same number. A box, a bag or a jar is part of how the thing is sold, so it belongs in the unit cost you price from, not as an afterthought.
3. A sale price you chose, and a margin you can see. Type a price. Look at the margin on that real unit cost. If the margin is thin, the price is too low — or the cost moved and the price did not. That is the loop. It does not need a public calculator inventing ingredient costs, and it does not need us to pick an hourly rate for you.

Labour is a time, not a cost we can honestly invent. Overhead is a different set of books (rent, energy, the van, the market pitch) and folding a made-up percentage into the sticker mixes two systems that should stay separate. We will not publish an hourly rate or an overhead percentage and put our name on it. Those numbers have to be yours, from your books, or they are the same guess the folk rules were.

The invert is then a sum you can do on the real unit cost, once you have a target margin you chose: unit cost ÷ (1 − target margin). We do not run that sum for you in the app today, and we do not ship a no-signup calculator that pretends to.

How ProvenBatch shows this

Recipe cost is calculated from the actual supplier pack behind each ingredient line, not a typed-in estimate, so two batches of the same recipe made with two different packs genuinely cost two different amounts, because they do. On Products, that unit cost (the recipe’s cost per unit, plus the packaging on that product) sits next to the sale price you type. Margin and margin % are that price minus that cost. Pricing decisions live on one screen, against a number that came from a real pack.

What it does not do: it does not suggest a selling price, it does not invent a labour rate, and it does not fold overhead into the sticker. If the margin looks wrong, change the price — or go and look at the pack.

Receipt scanning keeps the pack prices current (photographed, forwarded by email, or uploaded as a PDF; the photo is read by AI and stored privately with your records), which is why this is a habit rather than a one-off costing. When a pack price moves, the margin on the product moves with it. That is the point of pricing from the batch.
