Baker's Percentage Calculator for Bread, Pizza, and Pastry
The baker's percentage calculator turns any recipe into clean ingredient ratios, where flour is always 100% and every other ingredient is a percentage of that flour. Enter how much flour, dough, or how many loaves you want, and it computes each weight for you in grams or ounces.
It is built for home bakers and pros who want to scale a formula up or down without redoing the math, dial in hydration, and compare recipes on equal terms. Start from a preset, edit the percentages, and read the exact weights instantly.
How to Use the Baking Ratio Calculator
Choose a preset recipe
Pick one of the 12 presets at the top — from Basic Bread and Baguette to Sourdough, Croissant, and Banana Bread. Each one loads the standard baker's percentages for that recipe.
Set how to scale
Use Scale by to calculate from Flour weight, Total dough weight, or Number of loaves (enter the loaf count and weight per loaf). The other ingredient weights follow automatically.
Adjust and customize
Edit any ingredient's name or percentage right in the table, or use Add ingredient for your own. The hydration indicator updates in real time as you change the liquids.
Copy or save
Toggle between grams and ounces with the unit button, copy the full recipe as text, or save it to reload later from the Saved Recipes panel.
Features
Baker's Percentage Math
Flour is fixed at 100% and every other ingredient is a percentage of it, so weights stay proportional at any batch size.
12 Preset Recipes
Start from balanced ratios for Basic Bread, Baguette, Pizza Dough, Ciabatta, Focaccia, Sourdough, Brioche, Croissant, Challah, Pancakes, Banana Bread, and Muffins.
Hydration Indicator
A color-coded bar reads your dough's hydration as Low, Medium, or High so you can see how wet or stiff the dough will be.
Three Scaling Modes
Calculate by flour weight, total dough weight, or number of loaves — whichever number you already know.
Gram and Ounce Units
Switch between grams and ounces with one tap; entered weights convert instantly and your choice is remembered.
Editable Ingredients
Rename ingredients, change any percentage, add new rows, or delete ones you don't need to build a fully custom formula.
Copy as Text
Copy the whole recipe — ingredients, percentages, weights, total, and hydration — to your clipboard in one click.
Save and Reload
Save your custom recipes to local storage and reopen them anytime from the Saved Recipes panel.
Frequently Asked Questions
What is baker's percentage?
Baker's percentage is a baking notation where each ingredient is expressed as a percentage of the total flour weight. Flour is set at 100%, and everything else is measured against it. For example, 65% water with 1000g of flour means 650g of water.
How do you calculate baker's percentage?
Divide each ingredient's weight by the flour weight and multiply by 100. The calculator does the reverse too: enter a flour, dough, or loaf amount and it multiplies each stored percentage by your flour weight to give the exact grams or ounces.
Why is flour always 100%?
Flour is the base reference, so every other ingredient is expressed relative to it. Setting flour at 100% makes scaling simple — change the flour amount and every ingredient adjusts proportionally without touching its percentage.
What is hydration in baking?
Hydration is the percentage of liquid — water, milk, or eggs — relative to flour. The indicator labels it Low below 58%, Medium from 58% to 72%, and High above 72%. Higher hydration gives a more open crumb but stickier, harder-to-handle dough.
How do I scale a recipe with baker's percentage?
Use the Scale by menu. Flour weight is best when you know how much flour you have, Total dough weight when you need a specific final weight, and Number of loaves when you set a count and a weight per loaf. The percentages stay the same; only the weights change.
Can I add my own ingredients?
Yes. Click Add ingredient below the table, type a name and percentage, and its weight is calculated automatically from your flour amount. You can also rename or delete any non-flour row to make the formula your own.
How do I save a recipe?
Use the save button to store the current recipe, then open the Saved Recipes panel to reload or delete it. Recipes are kept in your browser's local storage, so they stay on your device and are never sent anywhere.
