Using total dough as 100%
Baker's percentage uses total flour as the base, not total dough weight.

Baker's Percentage Calculator for Bread Formulas
Baker's percentage turns a recipe into a formula: every ingredient is measured against total flour. That makes bread recipes easier to compare, adjust, and scale without fragile spreadsheet math.
Baker's Percentage is always free in The Baker, so it is a low-risk way to start building repeatable formulas.
Formula method
What baker's percentage is
In baker's percentage, total flour is always 100%. Every other ingredient is shown as a percentage of that flour weight.
Core formula
ingredient % = ingredient weight / total flour weight * 100This makes dough formulas portable. If hydration is 72%, salt is 2%, and prefermented flour is 20%, those relationships remain clear even when the batch size changes.
Worked example
Convert a bread recipe into baker's percentages
Example formula: 1000g flour, 720g water, 20g salt, and 2g yeast.
| Ingredient | Weight | Baker's percentage |
|---|---|---|
| Total flour | 1000g | 100% |
| Water | 720g | 72% |
| Salt | 20g | 2% |
| Yeast | 2g | 0.2% |
Multiple flours
How multiple-flour formulas work
If a formula uses bread flour, whole wheat, rye, or prefermented flour, the flour weights are combined first. That combined flour weight is the 100% base.
For example, 800g bread flour plus 200g whole wheat flour equals 1000g total flour. The bread flour is 80%, the whole wheat flour is 20%, and every non-flour ingredient is calculated against the same 1000g base.
Scaling formulas
Scale from one loaf to larger batches
Once a formula is expressed in baker's percentages, scaling is controlled by total flour weight or target yield. The ingredient relationships stay the same while the batch gets larger or smaller.
Scaling example
new ingredient weight = total flour target * ingredient percentageIf you scale to 5000g flour, 72% water becomes 3600g water and 2% salt becomes 100g salt.
Common mistakes
Where baker's math gets error-prone
Forgetting flour blends
All flour types need to be included in the total flour base.
Manual scaling drift
Rounding each ingredient separately can slowly change hydration, salt, and preferment ratios.

FAQ
Baker's percentage calculator FAQ
What is baker's percentage?
It is a formula system where total flour equals 100% and every other ingredient is measured as a percentage of flour weight.
Is baker's percentage free in The Baker?
Yes. The Baker's Baker's Percentage tool is included in the free version.
How do I handle more than one flour?
Add all flour weights together first. That total is the 100% base for the full formula.
Can baker's percentages scale a bread recipe?
Yes. Once a recipe is expressed as percentages, you can calculate new ingredient weights from a new flour target or batch size.
