Preferment Calculator
Preferment Calculator
Divide an entered flour and water formula into preferment and final mix.
A preferment moves part of the recipe's flour and water into an earlier mix. The final dough still needs a balanced ingredient total.
Set the preferment share and hydration, then inspect the ingredients left for the final mix. Apply the entered yeast rate on its stated flour basis.
How to use Preferment Calculator
- Enter total flour, overall water / flour and salt / total flour.
- Enter prefermented flour, preferment water / flour and yeast / preferment flour.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
The division keeps the earlier mix visible while preserving the overall flour and water plan.
