A useful starting point.

Sourdough Bench provides educational calculators and explanations for planning sourdough quantities. This page describes their intended use and limits.

Check your inputs

Use a consistent weight unit and check what each percentage means. Review the quantities before weighing ingredients, especially when adapting a recipe with milk, eggs, fats, sweeteners, or other ingredients outside the calculator's scope.

Understand the result

A correct calculation does not guarantee a particular rise, crumb, flavor, or schedule. The tools do not assess whether a starter is healthy, whether food is safe to eat, or when fermentation is complete. See the calculator and content disclaimer.

Use the site considerately

You are welcome to use the tools to plan your own bakes and to share links. Please do not interfere with the site's operation or describe its outputs as a professional certification or a recorded baking trial.
