About Dough Calculators
Dough Calculators is a small set of free tools for home bakers: sourdough hydration, pizza dough, starter feeding, and baker's percentage. No accounts, no paywalls, and no ads placed inside the calculator panels themselves.
How these tools are built and checked
Every formula on this site is checked against at least two independent, current baking references before it ships, and cross-referenced against professional sources like King Arthur Baking's own published methodology where one exists for that specific calculation. Where sources genuinely disagree, and in baking, they often do, that disagreement is stated plainly on the relevant page rather than papered over with a single confident-sounding number. Each calculator page links to a sourcing note explaining exactly how its numbers were verified.
