Bread Dough Calculator

How to Use This Tool

Select your preferred measurement unit (grams or ounces) and flour type from the dropdown menus. Adjust hydration, yeast, and salt percentages to match your recipe or preference. Choose how you want to scale your dough: by total flour weight, total dough weight, or number of 500g loaves. Enter the corresponding scale value, then click Calculate Dough to see your ingredient breakdown. Use the Reset button to restore default values, or Copy Results to Clipboard to save your ingredient list.

Formula and Logic

This calculator uses standard baker’s percentage principles, where flour is always 100% of the base weight. All other ingredients are calculated as a percentage of the total flour weight:

• Water weight = (Flour weight × Hydration percentage) / 100
• Yeast weight = (Flour weight × Yeast percentage) / 100
• Salt weight = (Flour weight × Salt percentage) / 100
• Total dough weight = Flour + Water + Yeast + Salt

If scaling by total dough weight or number of loaves, the tool first calculates the required flour weight by dividing the target dough weight by the total percentage sum (100 + hydration + yeast + salt), then multiplying by 100 to get the flour base.

Practical Notes

These tips help you adapt calculations to real-world home baking scenarios:

• Whole wheat and rye flours absorb more water than all-purpose or bread flour, so use higher hydration percentages (70%+) for these types.
• Active dry yeast and instant yeast use the same percentage calculations, but active dry yeast should be proofed in warm water before adding to dough.
• For cost planning, all-purpose flour averages 2-3 cents per gram, while specialty bread flour costs 4-5 cents per gram in most grocery stores.
• One 500g loaf yields approximately 12-16 slices, so scale your dough to match your household’s weekly bread consumption to avoid waste.
• If converting between grams and ounces manually, remember 1 ounce equals ~28.35 grams.

Why This Tool Is Useful

Home bakers often struggle to scale recipes up for large gatherings or down for single servings, leading to wasted ingredients or undercooked loaves. This calculator eliminates guesswork by adjusting all ingredients proportionally, so you get consistent results whether making one small loaf or enough dough for a week of sandwiches. It also helps you experiment with different hydration levels and flour types without ruining batches, saving time and money on trial runs.

Frequently Asked Questions

Can I use this calculator for sourdough starter?

This tool calculates commercial yeast amounts. For sourdough, replace 20% of the flour weight with active starter (adjust hydration to account for the starter’s 100% hydration ratio, where half the starter weight is flour and half is water).

What if my dough is too sticky after using the calculated amounts?

Stickiness usually means high hydration or humid weather. Add 1-2% more flour (by weight) and reduce water by the same amount in future batches to adjust for your kitchen’s conditions.

How do I adjust the recipe for high-altitude baking?

At altitudes above 3,000 feet, reduce yeast by 25% and increase water by 1-2% to account for faster rising times and drier air. You may also need to shorten proofing times by 15-20 minutes.

Additional Guidance

Always weigh ingredients instead of using volume measurements (cups, tablespoons) for the most accurate results, as flour density can vary by 20% or more between scooped and sifted cups. Let dough rest for 10-15 minutes after mixing to allow flour to fully absorb water before adjusting consistency. Store unused dough in an airtight container in the fridge for up to 3 days, or freeze for up to 3 months (thaw in the fridge overnight before baking).
