Sourdough starter feeding planner
Build a target starter amount with a stated seed:flour:water feeding ratio.
A clear answer. Here’s how.
Splits target mass in the seed starter : added flour : added water ratio, all by weight. Seed flour = seed mass/(1 + seed hydration/100), with the rest treated as water. Reports final flour, water and hydration. Predicts quantities only, without rise time, readiness or fermentation performance.

Worked example
A fixed demonstration, separate from the values you enter above.
- Target fed starter weight (g)
- 200
- Seed starter ratio part
- 1
- Added flour ratio part
- 2
- Added water ratio part
- 2
- Seed starter hydration (%)
- 100
Example result
- Seed starter
- 40 g
- Add flour
- 80 g
- Add water
- 80 g
- Total fed starter
- 200 g
- Total flour including seed
- 100 g
- Total water including seed
- 100 g
- Final hydration
- 100%
