About this calculator

The Baker's Percentage Calculator expresses ingredients as percentages of flour weight. It is useful for bread, pizza, sourdough, focaccia, and any dough formula where flour is the base.

Baker's Percentage Calculator method

The calculator applies the visible formula to the values entered. It is designed for practical planning and checking, so keep the assumptions visible when comparing scenarios.

ingredient percentage = ingredient weight / total flour weight x 100
ingredient weight = flour weight x percentage / 100

How to use the Baker's Percentage Calculator

Enter the total flour weight.
Enter water, salt, yeast, oil, sugar, or other ingredient weights.
Review each ingredient as a percentage of flour.
Use percentages to compare dough formulas.
Scale the flour weight to make a larger or smaller batch.
Adjust hydration and salt deliberately rather than by guesswork.

Worked examples

Basic dough formula

Input: 500 g flour, 350 g water, 10 g salt

Calculation: water = 350 / 500 x 100; salt = 10 / 500 x 100

Result: 70% hydration and 2% salt.

Scale from percentage

Input: 800 g flour, 65% water

Calculation: 800 x 65 / 100

Result: Use 520 g water.

When this calculator is useful

The Baker's Percentage Calculator expresses ingredients as percentages of flour weight. It is useful for bread, pizza, sourdough, focaccia, and any dough formula where flour is the base.

Use it as a quick planning tool before editing a recipe, placing an order, choosing packaging, or comparing options. For anything that affects safety, delivery terms, customer pricing, or a commercial commitment, check the final details against the original recipe, supplier, courier, or official source.

Inputs that matter most

Flour is 100%: All percentages are based on total flour weight, not final dough weight.
Hydration: Water percentage has a major effect on dough feel and crumb.
Salt: Salt percentage affects flavour, fermentation, and dough strength.
Scaling: Baker percentages make it easy to scale formulas accurately.

Common mistakes to avoid

Check 1: Preferment, levain, or starter flour and water may need to be included in total flour and water.
Check 2: Wet additions such as eggs, milk, honey, or oil affect dough feel.
Check 3: Wholemeal flour often absorbs more water.
Check 4: High hydration dough may need different handling techniques.

Planning notes

Area	What to check
Units	Keep grams, millilitres, centimetres, kilograms, and time units consistent.
Rounding	Round practical kitchen or shipping values after checking the calculated result.
Tolerance	Allow margin for packaging, recipe texture, oven variation, courier rules, or handling space.

Edge cases

Preferment, levain, or starter flour and water may need to be included in total flour and water.
Wet additions such as eggs, milk, honey, or oil affect dough feel.
Wholemeal flour often absorbs more water.
High hydration dough may need different handling techniques.

Limitations

This is general baking information. Use the result with recipe method, dough feel, and fermentation cues.

The calculator does not judge dough development, fermentation, or gluten strength.
Ingredient percentages are only as accurate as the weights entered.

Frequently asked questions

Why is flour always 100%?

Baker percentages use total flour weight as the reference point.

What is 70% hydration?

It means water weight is 70% of flour weight.

Do I include starter flour?

For accurate sourdough formulas, include flour and water from the starter or levain.

Is 2% salt normal?

Many bread formulas are near 2% salt, but taste and recipe style vary.

Can this scale pizza dough?

Yes. Pizza dough formulas commonly use baker percentages.

What does this mean?

This calculator is designed to help you understand the likely number before you make a decision or start an application.

Your result should be checked against official UK guidance, especially if your circumstances include dependants, exemptions, prior leave, or a complex immigration history.

Treat the figure as a planning tool rather than legal advice. Where the answer affects an application deadline or major payment, speak to an authorised adviser.
