Show the maths

  1. Starter flour

    Starter × 100 ÷ (100 + starter hydration)

    200 × 100 ÷ 200

    100g

  2. Added water

    Total water − water in starter

    700 − 100

    600g

  3. Final dough

    Total flour + total water + salt

    1000 + 700 + 20

    1,720g

Sourdough FAQ

What does starter percentage mean here?

Starter percentage is starter weight divided by total flour, including the flour contained in the starter.

Does starter hydration affect the calculation?

Yes. The calculator separates the starter into its flour and water components at the selected hydration so neither is counted twice.
