Baker's Percentage Calculator

Flour is 100%; every other ingredient is a percentage of it — the bread ratio every formula is built on. Enter grams to get percentages, or percentages to get grams, and it solves the other column for you.

How it works

For each row: if you typed grams, the percentage is grams ÷ flour × 100. If you typed a percent, the grams are percent × flour ÷ 100. If both are filled, the grams value wins. The total dough weight is the flour plus every ingredient — handy for splitting into loaves.

FAQ

Why do the percentages add up to more than 100%?

They're percentages of the flour, not of the dough. 100% flour + 70% water + 2% salt = 172% total, i.e. the dough weighs 1.72× the flour.

How do I hit an exact dough weight?

Divide your target dough weight by the total percentage (as a decimal). Want 900 g of a 172% formula? 900 ÷ 1.72 ≈ 523 g flour, then let the calculator fill in the rest.

How does my sourdough starter fit in?

Levain is usually written as its own line (e.g. 20%). To see how it changes your real hydration, use the sourdough hydration calculator.

Is a "bread ratio" the same as baker's percentage?

Yes — a bread ratio expresses each ingredient relative to the flour (100%), which is exactly what baker's percentage does. A 5:3 flour-to-water ratio is the same as 60% hydration, so this works as a bread ratio calculator too.
