Baker's Percentage Calculator
Calculate dough hydration, salt percentage, yeast or starter percentage, and total dough weight from the entered ingredient weights. The flour-bag visualization shows the actual formula composition while keeping flour as the baker's-percentage reference.

How to use Baker's Percentage Calculator
- Enter the total flour weight, including every flour used in the final dough.
- Enter water, salt, and yeast or starter consistently; if using a preferment, decide whether its flour and water will be broken into the totals.
- Review hydration and ingredient percentages before scaling the formula or adjusting fermentation.
Calculator guide
Understanding Baker's Percentage Calculator
Baker's percentage expresses every ingredient relative to flour, which is always 100%. This makes dough formulas easier to scale and compare than ordinary percentages, because the ingredient percentages do not need to add up to 100%.
Calculation method
How the calculation works
Treat flour as 100 percent and express water, salt, and yeast weights relative to total flour weight. Divide water, salt, and yeast or starter weight separately by flour weight and multiply each ratio by 100. Add all entered ingredient weights for total dough weight. A 70% hydration result therefore means 700 g water for every 1,000 g flour.
Formula reading
Why the percentages exceed 100%
Baker's percentages describe ingredient loading relative to flour rather than slices of one whole.
A formula with 100% flour, 70% water, 2% salt, and 1% yeast totals 173% of flour weight.
Worked situations
Practical examples
- With 1,000 g flour and 700 g water, hydration is 70%.
- Twenty grams of salt against 1,000 g flour is 2% salt, not 1.16% of total dough weight.
- The example formula totals 1,730 g of dough before fermentation loss, bench flour, fillings, or toppings.
Better inputs
Useful tips
- Include flour and water from a levain or preferment when comparing true overall hydration between recipes.
- Record flour type and protein level because two flours can behave differently at the same hydration.
- Scale by multiplying the desired flour weight by each baker's percentage rather than multiplying rounded ingredient totals.
Before relying on the result
Limitations and common mistakes
- The calculator does not separate flour and water contained inside starter, eggs, butter, milk, fruit, or other mixed ingredients.
- Absorption, dough temperature, mixing, autolyse, fermentation, salt timing, and flour age affect dough behavior beyond the displayed ratios.
- Total dough weight is theoretical and does not subtract bowl residue, evaporation, or handling loss.
Reference
Key terms
- Baker's percentage
- Ingredient weight divided by total flour weight, with flour defined as 100%.
- Hydration
- Water weight divided by flour weight, expressed as a baker's percentage.
- Preferment
- A portion of flour and water fermented before final mixing, such as poolish, biga, or levain.
- Total formula
- A formula that includes all flour and water contributed by preferments and mixed ingredients.
Important note
Calculated from the entered quantities using the displayed scaling or conversion method. Ingredient properties, preparation losses, serving needs, and food-safety requirements remain application-specific.
Frequently asked questions
Should starter be entered as yeast weight?
Only for a quick simplified comparison. For a true total formula, split the starter into its flour and water contributions and include those in the flour and water totals.
Why do ingredient percentages not total 100%?
Each ingredient is compared with flour independently. Flour is the common 100% reference, not the whole dough.
Does higher hydration always make better bread?
No. Appropriate hydration depends on flour absorption, product style, mixing, fermentation, shaping skill, and desired crumb.
Can the result scale a recipe?
Yes. Choose a new flour weight and multiply it by each baker's percentage, while preserving any preferment breakdown and process assumptions.
