Baking Ratio Calculator

What the Baking Ratio Calculator does (and why baker’s percentages matter)

The Baking Ratio Calculator helps you scale bread (and many lean doughs) using baker’s percentage—a professional method where flour is always the reference point at 100%, and every other ingredient is expressed as a percentage of the flour weight. This makes recipes easy to scale up or down without breaking the dough balance.

In this calculator, you enter:

- Flour (grams) - Hydration % (water as a percent of flour) - Salt % (salt as a percent of flour)

Then it calculates:

- Water (grams) - Salt (grams) - Total dough weight (grams)

This is especially useful when you want to: - Make the same dough size with different flour amounts - Adjust hydration for a tighter or looser dough - Keep salt consistent while scaling

Key idea: flour is the anchor. If you change flour, everything else follows.

The core formulas (exactly what the calculator is doing)

Let:

- Flour weight = F (in grams) - Hydration percent = H (for example, 65) - Salt percent = S (for example, 2)

Convert percentages to decimals:

- h = H / 100 - s = S / 100

Then compute:

1) Water (grams) Water = F × h

2) Salt (grams) Salt = F × s

3) Total dough weight (grams) Total = F + Water + Salt

### Rounding behavior (important) The calculator rounds results like this: - Water is rounded to the nearest whole gram. - Salt is rounded to 1 decimal place. - Total is rounded to the nearest whole gram.

That rounding is practical for kitchen use, but if you’re doing very small test doughs, the rounding can slightly shift the final total.

How to use the calculator step-by-step

1) Choose your flour weight (grams) Decide how much flour you want in the mix. This is the base for everything else. If you’re scaling a recipe, start by setting flour to the amount you want to use today.

2) Set your hydration % Hydration is the water relative to flour. Typical ranges: - 55–62%: firmer doughs (often easier to shape) - 63–72%: medium to moderately wet doughs (common for many loaves) - 73% and up: very wet doughs (more open crumb, stickier handling)

3) Set your salt % Common salt levels for lean bread dough are around 1.8–2.2% of flour weight. Lower salt can make dough feel slack and taste flat; higher salt can slow fermentation and taste overly salty.

4) Read the outputs: Water, Salt, and Total Use the water and salt weights directly in your mix. The total is helpful if you’re targeting a specific dough weight for a pan, banneton, or number of loaves.

Worked examples (with real numbers)

### Example 1: Basic lean bread dough (500 g flour, 65% hydration, 2% salt) Inputs: - Flour F = 500 g - Hydration H = 65% - Salt S = 2%

Convert: - h = 0.65 - s = 0.02

Calculate: - Water = 500 × 0.65 = 325 g - Salt = 500 × 0.02 = 10 g - Total = 500 + 325 + 10 = 835 g

Outputs (with rounding): - Water: 325 g - Salt: 10.0 g - Total: 835 g

How to use it: Mix 500 g flour with 325 g water and 10 g salt to get about 835 g of dough.

### Example 2: Scaling up for two loaves (900 g flour, 70% hydration, 2.2% salt) Inputs: - F = 900 g - H = 70% - S = 2.2%

Convert: - h = 0.70 - s = 0.022

Calculate: - Water = 900 × 0.70 = 630 g - Salt = 900 × 0.022 = 19.8 g - Total = 900 + 630 + 19.8 = 1,549.8 g

Outputs (with rounding): - Water: 630 g - Salt: 19.8 g - Total: 1,550 g

How to use it: This gives you roughly 1,550 g dough total, which can be divided into two pieces of about 775 g each (before baking loss).

### Example 3: Small test dough (300 g flour, 60% hydration, 1.8% salt) Inputs: - F = 300 g - H = 60% - S = 1.8%

Convert: - h = 0.60 - s = 0.018

Calculate: - Water = 300 × 0.60 = 180 g - Salt = 300 × 0.018 = 5.4 g - Total = 300 + 180 + 5.4 = 485.4 g

Outputs (with rounding): - Water: 180 g - Salt: 5.4 g - Total: 485 g

How to use it: Great for experimenting with a new flour or technique without committing to a big batch.

Pro Tips for better results when scaling recipes

- Use a scale and stick to grams. Baker’s percentages assume weight, not volume. Measuring cups introduce big variability, especially with flour. - Treat hydration as a starting point, not a promise. Flour type, age, and humidity change absorption. If your dough feels too tight, hold back a small portion of water at first, then add as needed during mixing. - If you change flour type, expect to adjust water. Whole wheat and high-extraction flours often need more water; very refined flours may need less. - Salt affects more than flavor. It tightens gluten and can slow fermentation. If you reduce salt percentage, watch fermentation timing and dough strength. - Use the total dough weight output to plan your batch. If you need a specific dough size (for example, to fit a pan), you can iterate flour up or down until the total matches your target.

Common Mistakes (and how to avoid them)

1) Confusing hydration with “percent of total dough” Hydration is water as a percent of flour, not of the final dough. A 65% hydration dough does not mean 65% of the dough is water.

2) Entering percentages as decimals If you type 0.65 for hydration, the calculator interprets that as 0.65%, not 65%. Enter 65 (not 0.65). Same for salt: enter 2, not 0.02.

3) Forgetting that this calculator only covers flour, water, and salt Many recipes include yeast, starter/levain, sugar, oil, eggs, or milk. Those ingredients change the real total dough weight and sometimes the effective hydration. Use this tool as a clean baseline for lean dough ratios, then add other ingredients deliberately.

4) Not accounting for preferments or sourdough starter If you use a starter, part of your flour and water are already inside it. To stay precise, you’d subtract the flour and water contributed by the starter from your target flour and water. (This calculator doesn’t do that automatically, but you can still use it by planning your flour and water totals first.)

5) Rounding issues in very small batches Because water and total are rounded to whole grams, tiny doughs can shift slightly. For small tests, consider keeping flour amounts large enough that 1 g rounding doesn’t matter much (for example, 250 g flour or more).

Quick reference: the key terms you’re actually controlling

- Baker’s percentage: Ingredient weights expressed as a percent of flour weight (flour = 100%). - Flour weight: The base number that scales everything. - Hydration: Water percentage relative to flour; strongly affects dough feel and crumb. - Salt percentage: Salt relative to flour; affects flavor, gluten strength, and fermentation. - Ingredient ratio: The relationship between flour, water, and salt that defines the dough style. - Total dough weight: Flour + water + salt (in this calculator), useful for planning portions.

Use the calculator whenever you want consistent, scalable dough math: pick your flour amount, choose a hydration and salt level, and you instantly get the water, salt, and total—clean, professional ratios without guesswork.
