About SourdoughCalc

SourdoughCalc is a free, fast, and accurate sourdough hydration calculator built for home bakers.

We believe great sourdough starts with the right ratios. Our calculator takes the math out of baking, so you can focus on technique, timing, and taste.

Why we built this

Most online calculators are either too complex, too cluttered with ads, or require signup. We built SourdoughCalc to be the opposite: free, instant, and beautifully simple.
