Quick start
Before you start
Turn baker’s percentages into a reproducible ingredient-weight formula, or work backwards from the final dough mass you actually need, while keeping preferment flour/water inside the same total flour and hydration authority.
Choose a mode, then have either total flour weight, target final dough weight, or the number and target weight of equal dough pieces. Enter your own hydration, salt and yeast percentages; preferment inputs are optional.
Total flour, water, salt, yeast, optional percentage-based extras, total dough mass, equal-piece information, baker’s percentages, preferment flour/water allocation and practical display-rounding difference.

Examples for home cooking and teaching
Choose a relevant example and check the assumptions before using it in your kitchen or lesson.
Start with the flour you have
Enter 1,000 g flour and your chosen percentages. The calculator derives water, salt, yeast, optional extras, total dough and any equal split you request.
Work backwards from pizza balls
Enter six 260 g dough balls and your chosen percentages. The calculator first sets the 1,560 g target, then derives the total flour and every formula ingredient from the total formula factor.
Plan bread dough pieces
Enter two 850 g loaf/dough pieces, or enter a 1,700 g final dough target, then use the same reverse baker’s-percentage maths for the ingredient split.
Use this againReturn when batch size, dough-piece weight, hydration, yeast, salt or prefermented-flour percentage changes.
Save one working formula on this device and reopen it with Load Saved Formula. My Resources detects only whether the known storage key exists; it does not inspect or display the formula payload.
Practical shortcut: Three clear modes keep flour-first, reverse target-dough and portion planning separate. Advanced preferment and extra-percentage inputs stay optional and never trigger fermentation-time predictions.
Trust & safety at a glance
Use the result for the decision it was built to support
A mathematically correct hydration or baker’s-percentage formula does not guarantee identical dough behaviour. Flour absorption, temperature, mixing, fermentation, handling and process remain separate variables.

How this Resource reaches its result
MethodDeterministic baker’s-percentage and target-dough calculator
Total flour is the 100% reference. Water, salt, yeast and optional extra ingredient masses are flour weight multiplied by their entered percentage. Reverse modes divide target total dough mass by the total formula factor. Prefermented flour is a partition of total flour, and preferment water is a partition of total formula water; neither is double-counted.
Can it be reproduced?Deterministic under this version
The same mode, target/flour weight, percentages, preferment convention and extras produce the same unrounded mathematical masses under the V16.4 contract. Rounding is display/export presentation only.
Evidence7 registered references · RecipeWanted review UNREVIEWED
Professional baking references support flour-as-100% baker’s percentage, formula-factor scaling/reverse scaling and accounting preferment flour/water inside the overall formula. RecipeWanted’s incompatibility guard is a conservative consequence of that accounting.
IndependenceNo paid or analytics influence over the result
Commercial inventory, analytics, saved-formula state and ecosystem links cannot alter formula factors, ingredient masses, preferment allocation or warnings. No runtime AI generates, repairs or adjusts the dough formula.
Uncertainty stays explicit: The calculator does not model flour absorption, dough temperature, ambient temperature, starter activity, yeast product equivalence, fermentation schedule, proof readiness, oven performance or bake time.

Bread & pizza dough calculator
Build a dough formula from flour, target dough or exact pieces
Start with flour weight, total dough needed, or the number and weight of portions. Baker’s percentages treat all flour as 100%: with 500 g flour, 60% water means 300 g water. A preferment is flour and water fermented before the final mix; its flour and water count inside the totals, not on top. Extra dough allowance is shown separately.
Formula authority — not fermentation prediction
Tool 11 calculates ingredient mass relationships only. It does not predict fermentation/proof time, dough temperature, starter activity, yeast-type equivalence, flour absorption, oven temperature, bake time, baked weight or food-safety status.
Presets are mathematical examples only. Replace them with the formula and process you actually intend to use.

Preferment allocation
Convention: prefermented flour is a percentage of total formula flour. Preferment water is part of total formula water. Neither is added twice.
Named flour allocation (optional)
These rows partition the existing total flour. They never add extra mass; any unallocated percentage remains “base flour”.
Other percentage-based ingredients (optional)
Use only ingredients intentionally expressed as baker’s percentages of total flour. These add mass and therefore belong in the formula factor.

How to read the result
Four controls that keep baker’s math honest
Named flour rows divide total flour; they do not add flour on top of the formula.
Preferment flour/water already exist in the overall flour/water totals and are subtracted from the final mix.
Reverse and portion modes can make extra dough, but requested target/piece mass remains visible separately.
Correct ratios do not determine fermentation, dough temperature, flour absorption, mixing or baking.

FAQ
Bread & pizza dough calculator questions
What does 100% flour mean in baker’s percentage?
All flour in the complete formula is added together and treated as 100%. Every other percentage is measured against that total flour weight. A flour blend still totals 100% flour; the blend rows only divide that flour into named parts.
Does hydration include water inside a poolish, biga or levain?
Under this calculator’s declared overall-formula convention, yes. Total hydration is total formula water divided by total formula flour. Preferment flour and water are allocations already inside those totals, so they are not added a second time.
Why can a preferment be rejected even if each percentage is within its own bound?
A preferment can mathematically demand more water than exists in the complete formula. If preferment water exceeds total formula water, final-mix water would become negative, so the calculator stops rather than displaying an impossible allocation.
Can I use the flour-blend rows for wholemeal, rye or another flour?
Yes, as an allocation of the existing total flour. The named blend percentages must stay at or below 100% combined. They do not change total dough mass. Changing flour type can change absorption and dough behaviour, so the same hydration may not handle identically.
What does production allowance do?
In target-dough or portion mode it increases the batch you make by the exact percentage you enter while preserving the requested net target or piece weights separately. It is an optional planning allowance for handling/process loss, not a prediction of how much dough your process will actually lose.
Does the calculator convert instant, active-dry and fresh yeast?
No. Yeast percentage is used exactly as entered. Yeast products differ and fermentation also depends on temperature, time, dough composition and process, so Tool 11 does not invent a yeast conversion or proof schedule.
Can this tell me how long to ferment or cold-proof the dough?
No. Baker’s percentage describes formula ratios, not fermentation kinetics. Flour choice, inoculation/yeast product, dough temperature, room/fridge temperature, mixing, salt, sugar, fat and desired outcome can all change the schedule.
Why are very small yeast quantities flagged?
A mathematically valid sub-gram value may be below the practical resolution of a normal kitchen scale. The calculator keeps the exact number but tells you when measurement precision deserves review.
Does the dough-piece weight predict baked pizza or loaf weight?
No. It is raw dough mass before baking. Baking and cooling change mass through moisture loss and other process effects, which this formula calculator does not predict.
Are the presets RecipeWanted recipes or recommended percentages?
No. Presets are labelled mathematical examples for testing the workflow. Replace every percentage and process assumption with the formula you actually intend to use before relying on the result.

Help RecipeWanted learn what is actually useful
Resources records aggregate usage statistics such as qualified tool views, whether a working surface is started, route-level value actions, coarse read depth, broad workflow/build-shape buckets and which non-commercial RecipeWanted handoffs are used. Build-shape signals are deliberately coarse (for example, a small/medium/large row-count bucket or a selected calculator mode): RecipeWanted does not send the recipe name, ingredient list, pantry items, allergen/dietary choices, free text or exact quantities to this analytics dataset; it does not create a visitor/session ID; and it does not store IP addresses, user-agent strings or referrer URLs in the analytics dataset.
Purpose: help RecipeWanted/QHE decide which free tools, workflows, supporting content and first-party integrations to improve next. Aggregate statistics may be reviewed internally across QHE only for that same RecipeWanted service-improvement purpose.
