The ingredients in a croissant cost very little. Its price reflects a production schedule that begins the previous day and a set of costs that run whether anything sells or not.

Lamination is measured in hours of waiting

A laminated dough is built by folding butter into dough repeatedly, with a rest and a chill between each fold so the butter stays solid and the gluten relaxes.

Those rests cannot be shortened without the layers merging, so the process occupies a working day regardless of how many pastries are being made.

Shaping, a final proof and baking follow, which is why bakeries producing these items start their day in the middle of the night.

Fermentation sets the schedule, not the baker

Yeasted and naturally leavened doughs develop on their own timetable, which shifts with the temperature of the room and the flour.

A baker cannot bring a proof forward to suit a rush, so production is committed hours before anyone knows what demand will be.

That commitment is why bakeries sell out rather than making more, and why the risk of unsold stock is priced into what does sell.

Skilled labour cannot be substituted easily

Shaping, judging proof and reading a dough by feel are learned over months, and a bakery losing an experienced baker loses capacity immediately.

Automating any of it requires equipment sized for volumes a small bakery does not have, so the labour stays manual.

Wages are therefore the largest line in the cost of most baked goods, well ahead of flour, butter and sugar combined.

Ovens and space cost money continuously

A deck oven runs for hours and consumes energy whether it is full or half empty, and heating it is a fixed cost per session.

Retarding cabinets, mixers and proving equipment all take floor space in premises rented by the square foot.

Those costs are spread across the items produced in a session, which is why small bakeries price higher per item than large ones at identical quality.

Waste is built into the model

Fresh baked goods have a shelf life of hours, and anything unsold at closing is either discounted, given away or discarded.

A bakery that never sells out is producing too much and absorbing that loss daily, so most deliberately underproduce.

The price of what sells therefore covers a share of what did not, which is a structural feature of selling something that cannot be kept.
