Bakers Percentage Calculator
Calculate bakers percentage for your recipes with our free tool. Get precise conversions, nutritional info, and serving adjustments.
Formula
Ingredient Weight = Flour Weight x (Baker's % / 100)
In baker's math, flour is always 100%. Every other ingredient is expressed as a percentage of the flour weight. To find the weight of any ingredient, multiply the flour weight by that ingredient's baker's percentage divided by 100.
Worked Examples
Example 1: Classic French Bread Formula
Problem: Calculate ingredient weights for a French bread with 1000g flour, 68% hydration, 2% salt, and 0.8% instant yeast.
Solution: Flour: 1000g (100%)\nWater: 1000 x 0.68 = 680g (68%)\nSalt: 1000 x 0.02 = 20g (2%)\nYeast: 1000 x 0.008 = 8g (0.8%)\nTotal dough weight = 1000 + 680 + 20 + 8 = 1,708g
Result: Total dough: 1,708g with 68% hydration. Makes two standard loaves.
Example 2: Scaling a Brioche Recipe
Problem: A brioche uses 500g flour, 60% hydration (eggs + milk), 10% sugar, 2% salt, 2% yeast, 40% butter. Scale to 750g flour.
Solution: Flour: 750g (100%)\nLiquid: 750 x 0.60 = 450g (60%)\nSugar: 750 x 0.10 = 75g (10%)\nSalt: 750 x 0.02 = 15g (2%)\nYeast: 750 x 0.02 = 15g (2%)\nButter: 750 x 0.40 = 300g (40%)\nTotal = 750 + 450 + 75 + 15 + 15 + 300 = 1,605g
Result: Total dough: 1,605g. Total baker's percentage: 214%.
Frequently Asked Questions
What are baker's percentages and why do professional bakers use them?
Baker's percentages are a standardized formula notation used in professional baking where every ingredient is expressed as a percentage of the total flour weight. Flour is always 100 percent, and all other ingredients are relative to that base. For example, if a recipe uses 1000 grams of flour and 650 grams of water, the water is 65 percent in baker's math. This system allows bakers to easily scale recipes up or down while maintaining consistent ratios. Professional bakeries rely on this method because it makes it simple to convert a home recipe to commercial batch sizes, or to compare hydration levels and ingredient ratios across different bread formulas without doing complex calculations.
What is hydration percentage and how does it affect bread texture?
Hydration is the percentage of water relative to flour weight and is the most critical ratio in bread baking. Low hydration doughs around 55 to 60 percent produce dense, tight-crumbed breads like bagels and pretzels. Medium hydration at 65 to 70 percent yields standard sandwich breads and rolls with a moderate crumb structure. High hydration doughs of 75 to 85 percent create open, airy breads like ciabatta and focaccia with large irregular holes. Very high hydration above 85 percent is used for batters and extremely wet doughs. Higher hydration doughs are stickier and harder to handle but generally produce bread with better flavor development and a more open crumb structure.
