Baker's Percentage Calculator

Baker’s percentage expresses every ingredient in a bread or pastry formula as a percentage of the total flour weight, with flour fixed at 100 percent. Because every other ingredient is stated relative to that one baseline, a formula scales to any batch size, in grams or ounces, without changing a single ratio, which is what prevents the drift in flavor and texture that plain volume scaling introduces.

Hydration, salt, sweeteners, fat, and yeast are the ingredients most often tracked as percentages, since each has a known target range that predicts dough behavior, fermentation speed, and crumb structure well before the dough is mixed.

List every ingredient in the formula as a weight in a single unit, with one row reserved for flour as the 100 percent reference. Multiple flour types can be combined into that one row, or kept in separate rows while their combined weight still supplies the reference total. Quantities convert freely between grams and ounces without changing any ratio, since baker’s percentage measures weight rather than volume.

An optional yield figure records the total dough weight the formula should produce, for planning a target number of loaves, rolls, or pizza dough balls. A multiplier scales the entire formula by a constant factor, such as 2 for a double batch or 0.5 for a half batch, while every ingredient’s percentage of flour stays identical.

Formula: percentage = (ingredient weight ÷ flour weight) × 100. The flour row always reads 100 percent by definition.

Read each percentage as the amount relative to flour. A hydration of 65 percent means water weighs 65 percent of the flour. Typical ranges include hydration at 58 to 75 percent for lean breads, salt at 1.8 to 2.2 percent, instant yeast at 0.2 to 0.8 percent for direct doughs, sugar at 2 to 10 percent in enriched doughs, and fats at 2 to 15 percent depending on style. Use these targets to compare formulas and predict fermentation speed, crumb structure, and crust color.

Lean Bread: a formula of flour 1000 g, water 650 g, salt 20 g, and instant yeast 3 g yields water at 65 percent, salt at 2 percent, and yeast at 0.3 percent. Doubling the multiplier to 2 produces a double batch with every ratio intact, and the yield figure then estimates total dough weight for planning pan counts or boule sizes.

Enriched Dough: a formula of flour 500 g, milk 300 g, sugar 60 g, butter 75 g, egg 50 g, salt 9 g, and yeast 5 g yields milk at 60 percent, sugar at 12 percent, butter at 15 percent, egg at 10 percent, salt at 1.8 percent, and yeast at 1 percent. Dropping yeast to 0.6 percent slows fermentation for a cold retard and extends proofing time.

Can multiple flours be used? Yes. Combine flours into one flour row for a single base, or keep them in separate rows to see each flour’s individual weight while their combined total still serves as the 100 percent reference.

Grams or ounces? Grams give finer precision in small batches; ounces work as well. Ratios stay identical either way, since baker’s percentage is unit-independent.

What about recipes listing cups and tablespoons? Weigh ingredients before entering them. Volume measurements vary with packing and brand, which reduces the accuracy of percentage-based scaling.

How is a hydration target reached? Set water to the desired percentage of flour. For a formula that tracks true hydration, subtract the water contributed by other liquids or eggs from that target.

How does yield scale with the recipe? A base yield multiplied by the scaling factor gives the updated total dough weight, which maps to pan sizes, loaf counts, or dough ball weights.
