Welcome to Omni's baker's percentage calculator, a simple and convenient tool to determine the proportion of a particular ingredient you need relative to the amount of flour you use. This proportion is called baker's percentage.

If you're a baking enthusiast, you've probably have heard that baking is an exact science. To achieve the desired outcome — whether it's a fluffy muffin, a pancake (our pancake recipe calculator has the best recipe out here), or cake — you must measure your ingredients precisely. One way you can implement a perfect recipe is to utilize the baker's percentage formula! Before you bake your batch made in heaven 🥧, come along to learn more about baker's percentage and to get answers to some questions, such as:

• What is baker's percentage?
• What is the baker's percentage formula?
• What is the baker's percentage in bread - and more!

## What is baker's percentage?

Baker's percentage (also known as baker's math) is a method to determine the proportion of ingredients when baking relative to the flour weight. You can use baker's percentage for many reasons, including:

• Needing precise proportions of ingredients with one unit of measure;
• Scaling recipes up or down without messing up the consistency of the dough or batter; or
• Experimenting with ingredients by changing only one of them while keeping other ingredient percentages constant.

## What is the baker's percentage formula?

Now, you are probably wondering how to calculate baker's percentage. Don't worry; the best is yet to crumb 😉. The formula for baker's percentage is quite simple:

baker's percentage = (ingredient weight / total flour weight) × 100%

To put the formula in perspective, we have an example for you. Let's say you were trying to bake a sourdough bread 🍞 that has the following ratio of ingredients:

Ingredient

Percentage

Flour

100%

Water

67%

Starter

20%

Salt

2%

For example, this would mean that we must add one part starter for each five parts flour we use in our recipe. "Part" can be any unit of weight — ounces, grams, kilograms, you name it!

So if you were to use 1.2 kg (1,200 g) of flour, then your measurements would be as follows:

Ingredient

Calculation

Weight

Flour

1,200g

Water

67 / 100 × 1,200 g

804 g

Starter

20 / 100 × 1,200 g

240 g

Salt

2 / 100 × 1,200 g

24 g

Simple enough? Try experimenting with your recipes with the help of the Omni baker's percentage calculator!

🙋 Remember that, in baker's math:

• Flour is always expressed as 100%; and
• The portions of all ingredients are not supposed to add up to 100%.

If you are a chemist, you may have noticed a similarity between the baker's percentage and measures of concentration. We explored them at our concentration calculator: we even have a percentage concentration to molarity calculator, that deals with the most similar measures to this cooking one!

## FAQ

### How do I calculate baker's percentage?

To calculate the baker's percentage for bread or any other baked goods:

1. Weigh the ingredient of your choice.
2. Divide the weight of your ingredient by the total weight of the flour.
3. Multiply the result by 100 to convert it to a percentage.
4. Voilà! You have now calculated the baker's percentage.

### What does 67% hydration mean in baker’s percentage?

67% hydration in baker's percentage displays how much water your dough or batter contains in proportion to flour. For instance, if you have 1,200 g of flour, 67% hydration means 804 g of water in the dough.

### What is the use of baker's percentage?

You can use baker's percentage in several ways, including scaling a dough or batter formula to make as many batches (or as few) baked goods as you desire — without messing up the recipe.

### What is the percentage of flour in baker's math?

The percentage of flour in baker's math is always 100%. Note that if you add up all percentages of ingredients in baker's percentage (including the flour) the sum will not equal 100%. The percentage indicates the quantity relative to the amount of flour.
