Baker’s Percentage Calculator
Express water, salt, yeast, and other ingredients as percentages of flour weight and total the dough.
How to use this calculator
- Replace the example values with your own measurements or planning assumptions.
- Keep every value in the unit printed beside its field.
- Select Calculate and review the result together with the formula and limitations below.
Formula and method
Each ingredient percentage equals ingredient weight divided by flour weight times 100. Flour is always 100%, and total dough is the sum of all entered weights.
Results are hidden whenever an input changes or validation fails, so an old answer cannot be mistaken for a current calculation.
Worked example
Flour weight = 1000 g; Water weight = 700 g; Salt weight = 20 g; Yeast weight = 5 g; Other ingredients = 100 g. The calculator returns Hydration = 70%; Salt percentage = 2%; Yeast percentage = 0.5%; Other ingredients = 10%; Total dough weight = 1,825 g.
The worked example uses the same default values displayed in the calculator.
Limitations and safety
Frequently asked questions
Why is flour always 100%?
Baker’s math uses total flour weight as the reference amount, so every other ingredient is compared with flour.
Why might the real result differ?
Baker’s percentages describe formula proportions, not fermentation behavior or food safety. Flour absorption and dough performance vary by flour, temperature, mixing, and process.
How should I round the answer?
Keep extra precision while planning, then round up when purchasing whole containers, bags, pieces, or stock lengths. Follow the output labels and supplier packaging.
