Adjusted for Cocoa Content, the "Cheap" Bar Is the Most Expensive One on the Shelf

There is one number the chocolate industry does not advertise.

It is not the price on the shelf. It is the price per gram of actual cocoa inside the bar. Once you calculate that number for the products sitting next to each other in the supermarket aisle, the entire idea of what is expensive and what is affordable stops making sense in the way you assumed it did.

The Bar That Keeps Getting Lighter

If your regular chocolate block feels lighter than it did a few years ago, that is not your imagination.

Here is an excerpt from Stuff documenting the long history of shrinkflation for Cadbury 

“Cadbury has done the downsizing move before, which created a big backlash online.

In 2009, it cut the family block sizes from 250 grams to 200 grams. But after customers complained it lifted the block sizes back to 220 grams in 2013.

That lasted two years because in 2015 it chopped the family-sized 220g blocks to 200g.

It also cut share packs from 200g to 180g, cut baking chocolate chip packets by 30g and single Freddo frogs were trimmed by 3g.

All these changes were also made with the explanation that it was a way to help keep chocolate affordable by cutting costs.” source

The Calculation They Hope You Skip

Think of it like buying orange juice. If one bottle is 10% real juice and another is 60% real juice, the second one is obviously better value, even if it costs a bit more on the shelf. Chocolate works exactly the same way.

The calculation is simple. Take what you pay per kilogram, then factor in how much of that bar is actually cocoa. What is left is the real price of the chocolate part, with all the sugar, packaging, and filler removed.

When you adjust for cocoa content:

Ferrero has always been a premium gift which relies on its fancy presentation box however it’s chocolate coating only contains 16% actual cocoa. The rest is sugar, hazelnut, and a very nice box. Once you run the numbers, you are paying up to $550 per kilogram of real cocoa. You are mostly paying for branding.

Kitkat looks affordable at around $55 per kilogram. But with only 20 to 25 percent cocoa in the coating, the real cocoa cost lands between $220 and $275 per kilogram. Everything else is wafers, vegetable fat, and lots of sugar.

The classic Mars bar has been shrinking since 2009, going from 60 grams down to 47 grams today with no drop in price. Its coating is about 25 percent cocoa. Sugar is the first ingredient on the label. Then glucose syrup. Then vegetable oil.

Bennetto costs $75 to $87 per kilogram on the shelf. At 60 percent cocoa, the real cocoa cost works out to $125 to $145 per kilogram.

On special Cadbury has a cheap price per kilo which is expected but the point is that if you are looking for chocolate there is more to consider than just the sticker price.

This is especially the case when you factor in quality and ethical sourcing concerns plaguing brands like Cadbury and Nestlé.

Why The Cocoa Percentage Is Not Just A Number

Cocoa percentage changes what the product physically is.

Cocoa butter, the natural fat inside real chocolate, melts at body temperature. That is what produces the clean, smooth melt that distinguishes high-quality chocolate from confectionery coating. When cocoa butter is replaced with vegetable oil or palm oil to keep costs down, the texture changes noticeably. The melt becomes slower, waxier, and slightly greasy. The flavour becomes flatter because cocoa solids are where the complexity lives, and there are fewer of them.

At 60 percent cocoa, Bennetto has enough cocoa mass and cocoa butter that the product does not need to be engineered around cheap substitutes. No PGPR. No vegetable fats stretching the coating. The formulation does not require shortcuts because the base ingredient is strong enough to carry it.

In 2024, cocoa prices peaked above $13,000 per metric ton, the highest in recorded history. The industry-wide response from mass-market brands was to use less of it: smaller bars, higher vegetable fat content, more filler. Higher-cocoa brands absorbed the same cost pressure but from a different starting point. Because their formulations were never built on minimum-threshold cocoa levels, they had less room to dilute and less incentive to try.

What You Are Actually Buying

Bennetto has not quietly swapped its formulation. The cocoa percentage is still the cocoa percentage. The ingredient list is still short and readable. The sourcing is transparent.

If you have been buying the same supermarket bar for years, there is a reasonable chance the product inside the wrapper has changed more than once since you started buying it. The name is the same. The wrapper colour is the same. But the weight, the price, and in some cases the formulation have all moved, and none of those changes were advertised.

Run the calculation on whatever you are currently buying. Price per kilogram on shelf, divided by cocoa percentage. Then run it on Bennetto.

The maths makes the case more clearly than anything else will.
