About the Baker's Percentage Calculator
Baker's percentage is the language professional bakers use to communicate recipes precisely, regardless of batch size. Unlike home-kitchen volume measurements, baker's percentage expresses every ingredient as a percentage relative to the total flour weight — flour is always 100%. This elegant system makes it effortless to scale recipes up for a commercial bakery or down for a single loaf.
Understanding baker's percentage unlocks the science behind great bread. A baguette typically runs 65–68% hydration, while ciabatta pushes 75–80%. By expressing recipes this way, you can quickly compare formulas, troubleshoot sticky doughs, and fine-tune crumb structure. Salt usually falls between 1.8–2.2%, and commercial yeast between 0.5–1.5%.
This calculator converts your recipe into baker's percentages and back again. Enter your flour weight and each ingredient amount to see the percentages, or start from a target formula and calculate exact weights for any batch size. Whether you're perfecting a sourdough boule or scaling up a brioche for the holidays, baker's percentage keeps your ratios locked in.
When This Page Helps
Baker's percentage is the professional standard for bread formulas because it keeps flour, water, salt, yeast, and enrichments in a consistent frame no matter how large the batch. This calculator makes it easy to compare doughs, scale production, and spot hydration changes before they affect the bake.
How to Use the Inputs
- Enter your total flour weight in grams or ounces
- Add each ingredient name and its weight
- View the calculated baker's percentage for each ingredient
- Adjust the flour weight to scale the entire recipe proportionally
- Use preset recipes to explore common bread formulas
- Toggle between metric and imperial units as needed
Formula used
Baker's Percentage = (Ingredient Weight ÷ Total Flour Weight) × 100. Total Dough Weight = Sum of all ingredient weights. Hydration % = (Total Water Weight ÷ Total Flour Weight) × 100.Example Calculation
Result: Hydration: 68%, Salt: 2%, Yeast: 1%
With 1000 g flour, 680 g water gives 68% hydration (680/1000×100). Salt at 20 g is 2%, and 10 g yeast is 1%. Total dough weight is 1710 g.
Tips & Best Practices
- Weigh ingredients in grams for the most accurate baker's percentages
- Keep a notebook of your favorite formulas in baker's percentage for easy reference
- Hydration below 60% makes stiff doughs (bagels); above 75% makes open-crumb artisan loaves
- If using multiple flours, add them all together as the 100% flour base
- Salt between 1.8% and 2.2% is the sweet spot for most bread
- Preferments like poolish count toward total flour and water percentages
Understanding Hydration in Baker's Percentage
Hydration is the single most important number in a bread formula. It determines crumb structure, crust character, and how the dough handles. Low-hydration doughs (55–60%) produce tight, chewy crumbs like bagels. Medium hydration (63–68%) yields classic sandwich and French bread. High hydration (72–85%) creates the large, irregular holes prized in artisan ciabatta and focaccia.
Common Baker's Percentage Formulas
A classic French baguette formula is 100% flour, 66% water, 2% salt, and 0.7% instant yeast. Pain de campagne adds 10–20% whole wheat or rye. Brioche is enriched with 50–60% butter and 15–20% eggs, pushing total hydration (from eggs, butter, and liquids) well above 100%.
Tips for Scaling Recipes
When scaling up, increase mixing time slightly to fully develop gluten. When scaling down to a single loaf (300–500 g flour), you may need to adjust yeast slightly upward because fermentation is faster in small batches. Always recalculate salt precisely — even a 0.5% difference is noticeable in the final bread.

Frequently Asked Questions
Baker's percentage expresses each ingredient's weight as a percentage of the total flour weight. Flour is always 100%, and every other ingredient is relative to it.
Flour is the foundational ingredient in baking. Using it as the baseline makes it easy to compare recipes and scale them to any size.
It depends on the bread type. Sandwich bread runs 60–65%, baguettes 65–68%, ciabatta 75–80%, and focaccia can go up to 85%.
Most bread formulas use 1.8–2.2% salt relative to flour weight. Too little and the bread tastes flat; too much inhibits yeast activity.
Yes! Baker's percentage works for any flour-based recipe including cakes, cookies, pie dough, and pastries.
Multiply each percentage by your desired flour weight and divide by 100. For example, 68% hydration with 500 g flour = 340 g water.
