What is the standard salt percentage for bread?

Most lean breads use 1.8%–2% salt relative to flour weight. Enriched doughs (brioche, milk bread) often sit at 1.5%–1.8% because fats and sugars offset flavor. Sourdough recipes commonly push to 2%–2.2% to slow wild-yeast fermentation and improve crust color.

Why express salt as a baker's percentage?

Baker's percentages stay constant no matter the batch size. Once you know a recipe works at 2% salt, you can scale to any flour weight and calculate salt in seconds — no re-testing required.

Can too much salt stop yeast?

Yes. Salt above roughly 2.5%–3% of flour weight starts to inhibit yeast noticeably. At 5%+ it can effectively halt fermentation. Staying in the 1.5%–2.2% range balances flavor with healthy yeast activity.

Does this work for sourdough?

Absolutely. Sourdough bakers often add salt after the autolyse (initial flour + water rest) to avoid slowing the starter prematurely. The percentage calculation is identical — just enter your total flour weight including any preferment flour.

Should I include preferment flour in the flour weight?

It depends on your formula style. Many professional formulas count total flour (preferment + main dough) as the base for salt percentage. Be consistent — if your recipe lists total flour, use that number here.

Summary

Enter your flour weight and target salt percentage to get the exact grams of salt needed, or reverse-calculate the percentage from a known salt weight.

How it works

Enter the total flour weight in grams — all baker's percentages are relative to flour.
Enter your target salt percentage (1.8%–2.2% is standard for most bread).
The calculator shows the exact grams of salt to add to your dough.
Use Reverse Mode: enter a known salt weight to find what percentage it represents.
Adjust hydration and salt together to see how ingredient weights shift with batch size.

Use cases

Scale salt precisely when doubling or tripling a bread batch.
Convert a printed recipe with gram weights into a reusable percentage formula.
Find the salt percentage in an existing recipe to compare it against baking standards.
Check whether a low-sodium bread formula falls within safe fermentation limits.
Teach baking students how salt affects gluten development and yeast activity.
Dial in consistent flavor across different loaf sizes without re-testing.
