Sourdough Recipe Calculator
Sourdough Recipe Calculator
Split total flour and water between a starter and the final mix.
A sourdough formula can be balanced around total flour and total water, with part of each arriving through the starter.
Enter the starter hydration and prefermented flour share, then check what remains for the final mix. Keep starter percentage and flour percentage distinct.
How to use Sourdough Recipe Calculator
- Enter total flour including starter, target total hydration, flour held in starter and salt / total flour.
- Enter starter hydration.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
The split lets you weigh the starter and final ingredients without counting the same flour or water twice.
Before you use the result
Prefermented flour percentage is not starter mass percentage. A formula that already has too much starter water is rejected.
Questions about Sourdough Recipe Calculator
Why can a requested formula be rejected?
A starter amount may already contribute more water than the target allows. Change the formula rather than treating a negative remaining quantity as an ingredient.
What should I check before using Sourdough Recipe Calculator?
Check Total flour including starter, Target total hydration, Flour held in starter and Salt / total flour. Use the exact units shown beside the controls and replace any example values with your own inputs.
