This baker’s percentage calculator speaks the professional language of bread: every ingredient as a percentage of the flour weight (flour = 100%) — converting percentages to grams for any batch size, and any recipe back into percentages.
Why Percentages Beat Recipes
A gram recipe dies at one batch size; a formula in baker’s percentages scales from 300 g to 300 kg without arithmetic drama, and bakers worldwide can read it at a glance — “75% hydration, 2.1% salt, 20% levain” is the bread. Applied to pizza specifically: our Pizza Dough Calculator. Part of our Food Calculators collection.
Worked Example (Verified)
- 500 g flour at the default formula: water 65% = 325 g · salt 2% = 10 g · yeast 1% = 5 g → total dough 840 g — two modest loaves or one generous one plus rolls
- Double the bakery, not the thinking: flour 1000 g turns every line by inspection (650/20/10) — the percentages didn’t change, which is precisely their job
- Salt discipline: 2% is the professional anchor (1.8–2.2% the sane band); recipes written in teaspoons hide 1.2% and 3% disasters behind spoon geometry
- Pre-ferments count inside the flour total: a formula listing “bread flour 80, whole wheat 20” bases percentages on the combined 100 — as the input note says, flour lines define the base
Formula Literacy in One Pass
- Hydration is the headline number; every other percentage is supporting cast.
- Enriched doughs add sugar/fat/egg percentages (brioche butter runs 40–60%!) — the same math, richer inputs.
- Seeds and inclusions are percentages too (15–25% typical), added on top of the base formula.
- When a recipe misbehaves, percentages make it debuggable: “raise hydration 3 points” is an instruction; “add a splash more water” is a hope.

Frequently Asked Questions
What is baker’s percentage?
Each ingredient’s weight expressed as a percentage of the total flour weight, with flour defined as 100%. Water at 65% means 65 g per 100 g flour. Because everything keys off flour, formulas scale by changing one number — the flour weight.
How do I convert a recipe to baker’s percentages?
Divide each ingredient’s weight by the flour weight and multiply by 100. A recipe with 600 g flour and 420 g water is a 70% hydration formula. If the recipe has several flours, their combined weight is the 100% base.
What hydration should my bread be?
Sandwich loaves 58–65%, classic rustic breads 65–75%, ciabatta and focaccia 75–85%+. Higher hydration = more open crumb and stickier handling; whole-grain flours absorb more, so they run 3–8 points wetter for the same feel.
How much salt and yeast are standard?
Salt: 2% (band 1.8–2.2%). Instant yeast: ~0.5–1% for same-day doughs, as low as 0.1–0.3% for overnight ferments — time and yeast trade against each other, and percentages make the trade explicit.
Does baker’s percentage include the starter/levain?
Yes — levain is typically quoted as a percentage of flour (15–30% common), and rigorous formulas also fold the starter’s own flour and water into the totals. This calculator treats each line independently: add your levain as a line and keep its internal hydration in mind.
