Small, accurate calculators for people who bake sourdough at home.

What’s here

Why another calculator

Most quick calculators treat the starter as if it were neither flour nor water, so the hydration they report is a few points off. Every calculator here counts what’s inside your starter and shows you both numbers, so you can follow any recipe the way it was written.
