Do the ingredient percentages need to add up to 100?

No. In baker’s math, 100% is always the flour. All other ingredients are expressed as percentages of the flour, so the total can be greater than 100%.

Can I include preferments, starters, or levain in this calculator?

Yes, but you need to account for their flour and water manually. You can either fold the preferment’s flour and water into the main flour and water totals or maintain a separate preferment formula and ensure the combined totals match your target baker’s percentages.

What hydration level should I start with?

Common starting points are 60–65% for sandwich loaves, 65–75% for many pizza and artisan breads, and 75%+ for high-hydration styles like ciabatta and focaccia. Use this calculator to move gradually between styles.

Should I round ingredient weights?

Yes. In practice, rounding to the nearest gram (or a practical value for very small amounts like yeast) is fine. Try to keep hydration and salt as close to target as possible for consistent results.

How should I treat inclusions such as seeds, nuts, or cheese?

You can either add them outside the baker’s percentage math or treat them as their own percentage of flour if you want consistency across batches. This calculator focuses on core dough ingredients; inclusions are typically handled separately.

Overview

This baker’s percentage calculator turns bakery-style formulas into exact gram weights. In baker’s math, flour is always 100%, and every other ingredient is expressed as a percentage of that flour weight. By entering your total flour weight and ingredient percentages, you get precise gram amounts for water, salt, yeast, sugar, and fat plus total dough weight and hydration—no spreadsheets required.

How to use this calculator

Choose how much flour you want in your final dough and enter that as Total flour weight (g). This becomes your 100% baseline.
Set your water, salt, yeast, sugar, and fat/oil percentages based on a known formula or the style of bread or pizza you want to make.
Review the output gram weights for each ingredient, the hydration %, and total dough weight.
If you need more or fewer loaves, adjust the flour weight and rerun the calculation—percentages stay constant, so the dough behaves the same at any batch size.
Experiment by nudging hydration or enrichment percentages to see how they change ingredient weights and total dough mass before you start mixing.

Inputs explained

Total flour weight (g): The total flour in your final dough, in grams. This is always treated as 100% in baker’s math. All other ingredient percentages are calculated relative to this number.
Water %: Water percentage relative to flour weight. This is your dough’s hydration. Typical ranges: around 60–65% for sandwich loaves, 65–75% for many pizza and artisan breads, and 75%+ for very open-crumb styles like ciabatta.
Salt %: Salt as a percentage of flour weight. Many formulas use roughly 1.8–2.5%. Higher salt levels increase flavor and tighten gluten but can slow fermentation.
Yeast %: Yeast as a percentage of flour weight. Higher percentages speed fermentation; lower percentages paired with colder temperatures support longer, slower rises. For sourdough, this might represent instant yeast-only formulas or supplemental yeast in hybrid loaves.
Sugar %: Sugar or sweetener percentage. Lean doughs often have little or no sugar, while enriched doughs (brioche, sweet rolls, certain sandwich breads) can be much higher.
Fat/Oil %: Fat or oil relative to flour weight. This can represent butter, oil, or other enrichments that soften the crumb and enrich flavor.

Outputs explained

Water weight (g): The exact grams of water required at your chosen percentage. This drives dough hydration and significantly influences handling and crumb openness.
Salt weight (g): The grams of salt to add. Accurate salt measurement keeps dough flavor and fermentation consistent from batch to batch.
Yeast weight (g): The grams of yeast you need for your chosen percentage and flour weight, which is especially helpful when working with small batches where teaspoons are imprecise.
Sugar weight (g): The grams of sugar or sweetener to add. This helps you fine-tune sweetness and browning without guessing.
Fat weight (g): The grams of fat or oil in the formula. This supports tenderness and richness in many breads and baked goods.
Total dough weight (g): The approximate total weight of the mixed dough, including flour and all other ingredients. Use this to plan loaf, roll, or pizza ball sizes.
Hydration %: Water weight divided by flour weight, expressed as a percentage. This is a key indicator of dough style and handling characteristics.

How it works

You start by entering a total flour weight in grams. In baker’s percentages, this flour weight is defined as 100% and acts as the anchor for every other ingredient.

For each ingredient, the calculator multiplies flour weight by (percentage ÷ 100) to get that ingredient’s weight. For example, with 1,000 g flour and 65% water, water weight = 1,000 × 0.65 = 650 g.

Total dough weight is then calculated by summing flour, water, salt, yeast, sugar, and fat weights. This helps you see how large the batch is and how many loaves or pizza balls you can divide it into.

Hydration is reported as hydration % = water weight ÷ flour weight × 100. Because water is defined as a percentage of flour, this value should match your water % input and gives you a quick sense of how wet the dough will be.

The calculator doesn’t directly manage preferments or multiple flours, but you can still apply the same logic by ensuring your flour and water inputs reflect everything that ends up in the dough, including levain, poolish, or biga contributions.

Formula

Ingredient weight = Flour weight × (Percent ÷ 100)\nTotal dough weight = Flour + Σ ingredient weights\nHydration % = (Water ÷ Flour) × 100

When to use it

Scaling a professional bread or pizza formula to different batch sizes without changing how the dough behaves.
Tweaking hydration, salt, and enrichment levels to experiment with new formulas while letting the calculator handle the gram conversions.
Converting cup-based recipes into baker’s percentage formulas so you can reliably repeat and scale them with a digital scale.

Tips & cautions

Small changes in hydration (even 1–2%) can have a noticeable impact on dough handling. Adjust in small steps and note what works best with your flour and environment.
Always weigh ingredients on a digital kitchen scale—volume measures are too inconsistent for accurate baker’s percentage calculations.
If you’re using preferments or sourdough starters, consider building a separate preferment formula using baker’s percentages, then folding its flour and water into your final dough totals.
Keep written records of successful formulas in baker’s percentage form so you can reproduce them at any batch size with this calculator.
The calculator assumes a single flour weight and does not automatically account for multi-flour blends or preferment contributions—those require you to aggregate flour and water manually.
It does not estimate fermentation times, proofing schedules, or temperature adjustments; those still depend on yeast activity, flour strength, and kitchen conditions.
Ingredient behavior can vary by brand and type (for example, different salts or flours), so treat the outputs as precise starting points that may still need small real-world adjustments.

Worked examples

Example 1: 1,000 g flour at 65% hydration, 2% salt

Flour weight = 1,000 g (100%).
Water% = 65 → Water weight = 1,000 × 0.65 = 650 g.
Salt% = 2 → Salt weight = 1,000 × 0.02 = 20 g.
If yeast = 1% and fat = 5%, the calculator will compute those weights and show total dough around 1,000 + 650 + 20 + yeast + sugar + fat g.

Example 2: Half batch, same formula

Flour weight = 500 g (still 100%).
At 65% water, 2% salt, and the same yeast/sugar/fat %, all ingredient weights are exactly half of the 1,000 g batch.
The dough behaves the same; you simply get half as much.

Deep dive

Use this baker’s percentage calculator to convert bakery formulas into precise gram weights for water, salt, yeast, sugar, and fat based on your flour weight. Enter flour grams and baker’s percentages to see ingredient weights, total dough weight, and hydration instantly.
