What Baker's Percentage Calculator does
The Sourdough Calculator on SourdoughGuru applies baker's-percentage logic to total dough planning, hydration, levain ratio, and salt percentages. It generates ingredient weights in grams and supports both standard and reverse workflows, allowing users to define dough weight per loaf, number of loaves, and levain hydration. The tool includes controls for flour blends, optional inclusions, and starter-related calculations within a single interface, producing a final recipe card with precise gram weights and percentage breakdowns.

Best for
Home bakers who want a single interface to plan sourdough loaves, adjust hydration and levain ratios, and calculate ingredient weights in grams without switching between multiple tools.
Limitations

- Results depend on user-entered percentages and may require manual adjustment for personal taste
- Levain components are automatically accounted for, but users must avoid adding levain flour and water as separate ingredients
Baker's Percentage Calculator FAQ
- Can I use this calculator for recipes with multiple flour types?
- Yes, the tool includes flour blend controls where you can add and adjust percentages for different flours, and you can specify which flour your levain is made from for accurate calculations.
- Does the calculator account for the flour and water already in the levain?
- Yes, the tool automatically accounts for the flour and water within your levain based on its percentage and hydration, so you should not add those components as separate ingredients.
- Is there a way to scale the recipe without re-entering all percentages?
- You can scale the recipe by adjusting the dough weight per loaf or the number of loaves; the percentages remain constant while the gram weights update automatically.
- What happens if my total flour percentage does not add up to 100%?
- The calculator requires the total flour percentage to add up to 100% for accurate weight calculations; entering values that deviate may produce unexpected results.
