What Sourdough Calculator does
The Sourdough Calculator helps home bakers determine the precise ratios of flour, water, starter, and salt needed for a loaf. Users input their desired total dough weight or flour amount, and the tool outputs the corresponding quantities of each ingredient, along with the starter's required flour and water based on its hydration level. The result is a complete breakdown of total dough weight, total flour, total water, and overall hydration percentage, ensuring consistent results every time.
How to use the Omni Calculator Sourdough Calculator
- 1
Enter the total weight of dough you want to make
- 2
Input your starter's hydration percentage and the flour it contains
- 3
Specify the amount of starter you plan to use
- 4
Review the calculated amounts of flour, water, and salt for your recipe
Best for
Home bakers who want to scale sourdough recipes confidently or experiment with hydration levels while keeping ingredient ratios consistent.
Limitations
- Results are based on baker's percentages and may need adjustment for personal taste or flour type
- Does not account for autolyse periods or specific baking methods
- Requires a functioning starter with known hydration to calculate starter components accurately
Sourdough Calculator FAQ
- Can I use this calculator if I don't have a sourdough starter yet?
- Yes, you can input a starter amount of zero; the calculator will then provide standard flour, water, and salt ratios for a basic recipe without a live culture.
- What does 'total hydration' mean in the results?
- Total hydration is the combined water from both the main recipe and the starter, expressed as a percentage of the total flour weight, giving you the true water content of the entire dough.
- How do I adjust the salt amount if I change the flour weight?
- The calculator applies a fixed salt-to-flour ratio; increasing or decreasing the flour weight will proportionally adjust the salt to maintain the recommended percentage.
- Is the starter hydration separate from the main dough hydration?
- Yes, the tool has a dedicated field for starter hydration and flour/water, which it uses to calculate the starter's contribution before adding the main water and flour amounts.
