Hydration, levain and a feeding schedule
Work out a dough from baker’s percentages, scale it, and time a starter feeding so the levain is ready when you mix. Everything runs in this page.

Starter feeding schedule
Build enough ripe levain for the mix above, plus a little left in the jar. Times use a peak window you set; they are a plan, not a guarantee — temperature changes how fast a starter rises.
FAQ
Is this sourdough calculator free?
Yes. It costs US$0 / KSh 0. An Android app is coming soon; this web page stays free.
What is baker’s percentage?
Total flour is 100%. Water, salt and levain are written as percentages of that flour weight. Hydration is water ÷ flour.
Is the levain part of the flour and water, or added on top?
Either. The default formula method keeps overall hydration honest by subtracting the flour and water already in the levain. “On top” adds a separately built levain after flour, water and salt are set, which raises the true hydration a little.
Is any data uploaded?
No. The calculator runs in your browser. Nothing is sent to a server.
