Why Baker's Percentage Matters

Consistency: Hydration, salt, and yeast ratios stay identical no matter how much dough you're making.

Easy scaling: Double or halve a recipe by keeping percentages fixed and changing only the flour weight.

Recipe comparison: Quickly compare hydration levels or fat content across different bread or pastry recipes.

Professional standard: Used in commercial and artisan bakeries worldwide for formula documentation.

Baker's percentage (also called baker's math) is a system professional bakers use to express every ingredient in a recipe as a percentage of the total flour weight. Flour always equals 100%, and everything else — water, salt, yeast, sugar, fat — is measured relative to it. This makes it easy to scale a recipe for any batch size, from a single loaf to a 50 kg commercial mix, without recalculating every ratio by hand.

Formula

Baker's Percentage = (Ingredient Weight ÷ Total Flour Weight) × 100

How to Use This Calculator

1. Enter the ingredient weight (e.g., water, salt, sugar, butter) and select its unit (mg, g, dag, kg, oz, lb, st).
2. Enter the total flour weight used in the recipe, in the same or a different unit — the calculator converts automatically.
3. The baker's percentage updates instantly, showing that ingredient's weight relative to flour.
