Baker's Percentage Calculator

Flour = 100%; every other ingredient as a % of flour by weight. Universal scaling for breads and doughs.

Inputs

Instant yeast 0.7-1%; sourdough starter 15-25%.

Enriched dough 5-12%; lean dough 0%.

  • Total dough1,730.0 g

Step-by-step

  1. Each ingredient = flour × percentage.
  2. Water = 1000 × 0.7 = 700.0 g.
  3. Total = flour × (1 + sum of %s) = 1000 × 1.7300 = 1,730.0 g.

How to use this calculator

  • Enter flour weight you want to start with.
  • Enter hydration % (water as % of flour).
  • Enter salt, yeast, fat, sugar percentages.
  • Read the resulting dough composition.

About this calculator

Baker's percentage is the universal way to express bread recipes: flour is always 100%, every other ingredient is a percentage of flour by weight. A "70% hydration" sourdough means 700g water per 1000g flour. This makes recipes infinitely scalable — keep the percentages, change the flour weight to whatever you want. Standard ranges: hydration 60-85% (lean breads), salt 1.8-2.2%, instant yeast 0.5-1.5%, sourdough starter 15-25%, enrichments (fat/sugar) 0-15%.

Frequently asked

More than 2.5% inhibits yeast and is unpleasantly salty. Less than 1.5% makes dough slack and bland. The 1.8-2.2% sweet spot is universal in pro bakeries.
