Ask a biscuit supplier what a butter biscuit costs to make and you usually get one number. That number is made of seven moving parts, and in the last 12 months they moved in opposite directions.
This post takes a typical butter biscuit apart. It shows what each layer of cost is, how big it is, what happened to it over the past year, and which levers a manufacturer or a private-label buyer can actually pull. It is one worked example of should-cost analysis: estimating what a product ought to cost from its inputs, rather than taking the quoted price as given.
It is written for procurement and finance teams at industrial bakeries, and for retail buyers sourcing private-label biscuits. It is not about building a plant.
What does it cost to make butter biscuits?
The cost of making butter biscuits is mostly the cost of what goes into them. In our illustrative model, butter, wheat flour, sugar and egg make up 62% of unit cost, packaging 10%, energy 8%, and labour, overhead and margin the remaining 20%. Butter is the single biggest line, so the dairy market sets the tone, but energy moves fastest.
We use the same illustrative shares as our guide to responding to a supplier price increase, so the two posts can be read together. They are an assumption for teaching, not a measured industry average. Replace them with your own supplier’s breakdown as soon as you have it.
The cost stack of a butter biscuit
| Cost layer | Share of unit cost (illustrative) | What sits in it |
|---|---|---|
| Butter | 25% | The main fat, and the reason it is a butter biscuit |
| Wheat flour | 20% | Milled soft wheat, the bulk of the dough |
| White sugar | 12% | Sweetness, colour and spread in the oven |
| Egg | 5% | Whole egg, often as powder or liquid |
| Packaging | 10% | Tray, flow wrap or gift box, plus the printed carton |
| Energy | 8% | Mostly gas for the ovens, plus power for mixing and cooling |
| Labour, overhead, margin | 20% | Line staff, maintenance, depreciation, logistics and the maker’s margin |
| Total | 100% |
Cost shares are illustrative, matching our supplier price increase example.
Two things stand out.
First, butter carries more cost than wheat flour, although the dough holds more of the latter by weight. A biscuit’s cost is driven by its most expensive kilo, not its heaviest one.
Second, 80% of the cost is bought in. Ingredients, packaging and energy are all market-priced. Only the last 20% is under the plant’s own control, and even labour follows wage agreements. That is why a cost model for this product is mostly a commodity model.
For bakery manufacturers, this shape is typical of the short-dough category: shortbread, butter cookies, sablés and their private-label versions.
The recipe and where yield goes
Cost shares only make sense next to the recipe. A butter biscuit is a short dough: lots of fat, little water. Published recipes and the classic 3:2:1 shortbread ratio (wheat flour, butter, sugar by weight) put a typical recipe in these ranges:
| Ingredient | Typical share of dough weight | Job in the biscuit |
|---|---|---|
| Wheat flour | 40% to 50% | Structure |
| Butter | 25% to 33% | Texture, flavour, the “short” bite |
| Sugar | 15% to 25% | Sweetness, browning, spread |
| Egg | 0% to 10% | Binding and colour (shortbread uses none) |
| Salt, raising agent, flavour | under 2% | Small cost, small weight |
Ranges from published shortbread and butter biscuit recipes; individual products vary.
Not every kilo of dough becomes a kilo of sellable biscuit. Three losses sit between the mixer and the pack:
- Bake loss. A short dough carries little water, so it loses less weight in the oven than bread. But it still loses some, and the loss rises with darker bakes.
- Breakage and rejects. Butter biscuits are fragile. Broken pieces, misshapes and edge trim go to rework or waste.
- Giveaway. Under the EU average-quantity rules for e-marked packs, packers set fill weights slightly above the declared weight to stay compliant. Every gram above the label is ingredient cost given away.
Yield doesn’t get its own line in the cost stack, but it sits inside every ingredient line. We come back to it in the levers.
What moved in the last 12 months
Here is how each input changed over roughly the past year, using the latest available price against the same date a year earlier.
The details behind each bar:
- Butter. Butter prices in Europe (VPI, EXW) fell 22.9% between 22 Oct 2025 and 21 Oct 2026.
- Wheat flour. French wheat flour quotations (EXW Île-de-France, from the trade publication Réussir) rose 24.2% between 14 Oct 2025 and 13 Oct 2026.
- Sugar. The West-EU white sugar benchmark (VPI, DAP) rose 13.2% between 22 Oct 2025 and 21 Oct 2026.
- Eggs. The European whole egg powder market (caged, VPI) fell 22.9% between 23 Oct 2025 and 22 Oct 2026.
- Packaging. Our partner FBB boxboard price data (280 gsm, West-EU) shows a 3.3% fall from October 2025 to October 2026.
- Energy. German THE natural gas futures (front month, EEX) rose 115.3% between 13 Oct 2025 and 13 Oct 2026. We use the THE hub rather than TTF because many EU bakery gas contracts price off a national hub.
The ranges inside the year were wide too. Butter’s 12-month high was 37.8% above its low, white sugar’s 41.9% and egg powder’s 36.5%. A biscuit cost that looks stable on an annual comparison can swing hard from quarter to quarter.
A note on dates. Our supplier price increase guide used prices from about a week earlier and showed butter at -28.6% year on year. One week of difference in the base and end dates moved butter’s annual change by almost six points. That is normal for a volatile series, and it is why every percentage here comes with its dates.
What that did to unit cost
To turn price moves into a cost change, weight each one by its share of unit cost. A 22.9% fall in an input that is 25% of cost takes about 5.7 points off the total. A 115.3% rise in an input that is 8% of cost adds about 9.2.
| Input | Share of unit cost | 12-month move | Effect on unit cost |
|---|---|---|---|
| Wheat flour | 20% | +24.2% | +4.84 points |
| Butter | 25% | -22.9% | -5.73 points |
| White sugar | 12% | +13.2% | +1.58 points |
| Whole egg powder | 5% | -22.9% | -1.15 points |
| Packaging (FBB boxboard) | 10% | -3.3% | -0.33 points |
| Energy (THE gas) | 8% | +115.3% | +9.22 points |
| Labour, overhead, margin | 20% | held flat | 0 points |
| Total | 100% | +8.4% |
Our calculation from the moves above. Cost shares are illustrative.
Three readings of that table:
Ingredients nearly cancelled out. Butter and egg powder took 6.9 points off. Wheat flour and sugar put 6.4 back. Add packaging and the whole bill of materials, everything except energy, is down about 0.8%.
Energy is the whole story. At 8% of cost, it is the second-smallest line in the stack. It is also the reason unit cost is up. Without it, this biscuit would cost slightly less to make than a year ago.
The supplier guide’s 7.7% and this post’s 8.4% are both right. They use different dates and slightly different series (German sugar against West-EU sugar, liquid egg against egg powder, recycled board against FBB). The method is identical. What matters is that you match the series to what your supplier actually buys.
To put it in money: if a private-label 200 g pack costs the manufacturer €1.00 to make, +8.4% is about 8 cents a pack. Butter’s fall saved almost 6 cents of that; gas added just over 9.
Two limits are worth stating. The model applies the spot gas move to the whole 8% energy share, but most bakeries have bought part of their energy forward, and electricity follows its own path. And labour is held flat; if wages rose, add a line with the evidence.
The levers: what actually lowers biscuit production cost
Once you know the stack, you can see which levers are worth pulling. These apply whether you run the line or buy the finished biscuit and want to know what your supplier can do.
Lever 1: the fat in the recipe
Butter is 25% of cost, so the fat is the biggest single lever. Every 10% less butter in the recipe takes about 2.5 points off unit cost, before you pay for whatever replaces it.
The usual replacement is vegetable fat, often palm-based. Vegetable fat is cheaper per tonne than butter, which is why the swap exists. But the last 12 months show how the saving moves with the market. The West-EU RBD palm oil market (VPI) rose 4.5% while butter fell 22.9%. The gap between the two fats narrowed, so a reformulation priced a year ago would save less today.
Palm oil also didn’t buy stability: its 12-month high was 45.6% above its low, a wider swing than butter’s 37.8%.
And the fat is not just a cost line. Swap it and the product stops being an all-butter biscuit, which ends the claim on the pack and changes the taste. Palm brings its own sourcing requirements, including deforestation due diligence under the EU’s EUDR. For a premium butter biscuit, partial blends or a smaller pack usually beat a full swap.
Lever 2: sugar
Sugar is 12% of cost and rose 13.2%, adding 1.6 points. Cutting it is harder than it looks: sugar drives spread, colour and crunch in a short dough, and a lower-sugar biscuit often needs a new process, not just a new recipe. Where it makes sense, it is usually part of a health reformulation rather than a cost project.
Lever 3: pack format and cartonboard
Packaging is 10% of cost here, but that share depends heavily on the format. A tin or a premium gift carton can carry far more, and a large flow-wrapped family pack far less. Smaller packs and multipacks raise packaging cost per kilo of biscuit.
Board fell 3.3% this year, so the lever is not the board price. It is grams of board per kilo of product: carton weight, a printed sleeve instead of a full carton, or fewer packs per case.
Lever 4: how energy is bought and used
Energy was 8% of cost and added 9.2 points. Two parts:
- Buying. A bakery that fixed part of its gas a year or more ahead is not paying the 115% rise on all of its volume. Layered forward buying, where you fix a share of each future quarter in stages, smooths the move. If you buy finished biscuits, ask your supplier how much of its next 12 months of gas is already fixed.
- Using. Ovens burn gas while warming up and idling. Longer runs, fewer changeovers, heat recovery and tighter oven profiles all lower gas per tonne.
Lever 5: yield and giveaway
Yield is the lever nobody prices. If 5% of dough is lost to breakage and rejects and you bring that to 3%, you need about 2% less material per sellable kilo. On a 62% ingredient share, that is roughly 1.3 points off unit cost (our calculation, illustrative waste rates).
Giveaway works the same way. Overfilling every pack by 2% adds about 1.2 points to unit cost. Tighter checkweigher settings get that back without touching the recipe.
Neither shows up in a commodity price. Both show up in the cost of every pack.
Putting it to work
A biscuit’s cost is a weighted sum. Once you have the weights, every market move turns into points of unit cost you can check, and every lever has a size.
For the wider view of how wheat and butter trends feed bakery margins, see our post on how soft wheat and butter price trends impact your bakery margins.
To run this for your own products, build a should-cost model with your real recipe and cost shares, then link each line to a price series. If a supplier has just sent a price increase on biscuits, the supplier price increase guide linked above turns the same arithmetic into a seven-step response.
Vesper cost models do this automatically: your recipe, linked to live benchmarks for butter, wheat flour, sugar, egg, packaging and energy, so you can see what your biscuit should cost today and which input moved it.
Frequently asked questions
How much does it cost to make butter biscuits?
It depends on the recipe, the pack and the plant, so the useful answer is the cost structure. In our illustrative butter biscuit, ingredients make up 62% of unit cost (butter 25%, flour 20%, sugar 12%, eggs 5%), packaging 10%, energy 8%, and labour, overhead and margin 20%. Use your own supplier's breakdown where you have one.
What is the biggest cost in making butter biscuits?
Butter. In our illustrative cost stack it is a quarter of unit cost on its own, more than flour, even though flour is the heavier ingredient in the recipe. That is why a butter price move shows up in biscuit cost faster than almost anything else.
Why did biscuit production cost rise when butter prices fell?
Because energy rose much more. In the 12 months to October 2026, European butter fell 22.9% (VPI) while German THE gas more than doubled (+115.3%, EEX). Weighted by their shares of cost, butter took 5.7 points off unit cost and energy added 9.2. Flour and sugar added more, and the net result was about +8.4% in our example.
Does switching from butter to palm fat lower biscuit cost?
Usually, because vegetable fat costs less per tonne than butter. But the saving moves with the market: over the past year butter fell 22.9% while RBD palm oil rose 4.5%, so the gap narrowed. Palm oil was also more volatile, and a fat swap ends any all-butter claim on the pack, so price it as a product decision, not just a cost one.
How do I check if my biscuit supplier's price increase is fair?
Ask for the supplier's cost shares, then multiply each share by that input's price change from an independent index over the same period and add the results. Compare that figure with the increase they asked for. Our guide to responding to a supplier price increase walks through the full method.
