Variables
- Flour Weight (Base – 100%): The mass of the primary flour used in the recipe. This value is always set as the denominator in the formula, equating to 100%.
- Water Weight: The mass of water, liquid starter, or other liquid ingredients. Typically ranges from 60% to 80% for bread.
- Salt Weight: The mass of salt. Essential for flavor and controlling yeast activity, commonly 1.8% to 2.2%.
- Yeast Weight: The mass of yeast (instant, active dry, or fresh). Its percentage depends on the type and desired fermentation time.

What is Baker’s Percentage?
Baker’s Percentage (also known as Baker’s Math) is a mathematical notation system used in baking that expresses the amount of each ingredient as a percentage of the total flour weight. Regardless of whether the recipe is for a single loaf or a commercial batch, the flour is always designated as 100%.
This system provides immense value to bakers because it establishes a universal, scalable ratio. By knowing the percentages, a baker can easily adjust the total yield (e.g., scaling up from 500g of flour to 50kg) while preserving the precise flavor profile and dough consistency. It is the fundamental language for communicating recipes professionally.
Crucially, the total percentage of a recipe in Baker’s Math is almost always over 100%, as it includes the 100% flour base plus all other ingredient percentages.
How to Calculate Baker’s Percentage (Example)
Follow these steps to calculate the percentages for a simple dough recipe:
- Identify the Flour Weight: Start with the flour weight. Assume $W_{\text{Flour}} = 500 \text{g}$. This is your base (100%).
- Determine Ingredient Weights: List all other ingredient weights. E.g., $W_{\text{Water}} = 350 \text{g}$, $W_{\text{Salt}} = 10 \text{g}$.
- Calculate Water Percentage: Divide the water weight by the flour weight and multiply by 100. $$ \text{Water } \% = (350 \text{g} / 500 \text{g}) \times 100 = 70.0\% $$
- Calculate Salt Percentage: Divide the salt weight by the flour weight and multiply by 100. $$ \text{Salt } \% = (10 \text{g} / 500 \text{g}) \times 100 = 2.0\% $$
- Summarize Results: The recipe is $100\%$ Flour, $70.0\%$ Water, and $2.0\%$ Salt. Total percentage is $172.0\%$.
Frequently Asked Questions (FAQ)
Is Baker’s Percentage the same as standard percentage?
No. Standard percentage is relative to the total weight of the final product (must always sum to 100%). Baker’s Percentage is relative to the flour weight (the base), meaning the total percentage will almost always exceed 100%.
Why is flour always 100%?
Flour is the main structural component of most baked goods. Establishing it as the 100% baseline allows bakers to quickly assess and compare the ratio of liquids (hydration), salt, and yeast across different recipes universally.
What is “hydration” in Baker’s Math?
Hydration is the baker’s percentage of water (or total liquid) relative to the flour. A higher percentage (e.g., 75%) indicates a wetter, often stickier dough, while a lower percentage (e.g., 60%) indicates a stiffer dough.
How do I use this calculator to scale a recipe?
First, enter the original recipe’s weights to find the percentages. Once you have the percentages, decide on your new desired flour weight (e.g., 1000g). You then multiply the new flour weight by the calculated percentages to find the new required ingredient weights.
