This free brioche butter percentage calculator scales an enriched brioche dough from your flour weight and your chosen butter percentage. Enter the flour and slide the butter percent up or down, and the tool gives butter, milk, sugar, yeast, salt and eggs to match, so rich and light versions both work.
Butter percentage is the single number that defines brioche. At 30 percent the bread is soft and lightly rich, at 50 percent it is the classic golden loaf, and above 70 percent it turns towards a cake-like crumb that needs gentle handling. Knowing the percent lets you compare recipes honestly instead of guessing from vague words like rich or light.
To use the tool, enter your numbers in the fields above and press the calculate button. The results table updates at once, and you can change any number and calculate again as often as you like.

The formula is baker percentages on flour: butter at your chosen percent, milk at 20 percent, sugar at 10 percent, instant yeast at 1.5 percent and salt at 1.8 percent. Eggs run at about one egg per 250 grams of flour, which keeps the dough yellow and tender without turning it into cake batter.
Example: for 500 grams of flour at 50 percent butter, the tool gives 250 grams of butter, 100 grams of milk, 50 grams of sugar, 7.5 grams of yeast, 9 grams of salt and about 2 eggs. Add the butter soft, in small pieces, only after the dough has come together, or the fat will coat the flour and weaken the gluten.
Tip: keep the butter cool but soft. Butter straight from the fridge tears the dough, while melted butter makes it greasy, so butter that dents easily with a finger but still holds its shape is exactly right.
Tip: expect a long, slow rise. Enriched doughs rise slower than lean doughs because fat and sugar slow the yeast, so give brioche a full first rise and a patient proof, and judge by size, not by the clock.
Tip: chill the dough before shaping. Cold brioche dough is firm and easy to braid or mould, while warm, buttery dough sticks to everything and loses its shape on the tray.
Common question: What butter percentage makes classic brioche? Around 50 percent of the flour weight is the classic middle ground: clearly rich, still sliceable, and golden. Drop to 30 percent for everyday sandwich brioche, or rise towards 70 percent for a dessert-style loaf.
Common question: Can I use salted butter for brioche? You can, but reduce the added salt a little. Salted butter varies by brand, so unsalted butter plus the measured salt in this tool gives the most repeatable result.
Common question: Why is my brioche dense? The usual causes are butter added too early, which weakens gluten, or under-proofing, which leaves the loaf tight. Add butter late, in pieces, and let the shaped loaf nearly double before baking.
Timing and storage matter as much as the numbers. Make the dough when you have time for a slow rise and a proper bake, not rushed between other jobs, because bread rewards patience far more than speed. Store finished bread in a way that protects the crust you worked for, and reheat gently rather than microwaving it soft.
A note on accuracy: weigh your ingredients with a kitchen scale, because cup measures vary by how flour is scooped and packed, and a 10 percent flour error changes hydration enough to notice. Check your scale with a known weight now and then, and keep the same units through the whole recipe so nothing gets converted twice by mistake.
This tool is free to use as often as you like. Bookmark it, run it for every batch, and let it carry the measuring while you focus on shaping, baking and enjoying the bread itself.
