Step-by-step calculation
- 1.Base flour: 500g
- 2.Water = 500g × 75% = 375g
- 3.Starter = 500g × 20% = 100g
- 4.Salt = 500g × 2% = 10.0g
- 5.Total dough weight = 500 + 375 + 100 + 10.0 = 985g
- 6.--- True hydration (including starter) ---
- 7.Starter flour contribution: 100g ÷ 2 = 50g
- 8.Starter water contribution: 100g ÷ 2 = 50g
- 9.Total flour = 500 + 50 = 550g
- 10.Total water = 375 + 50 = 425g
- 11.True hydration = 425 ÷ 550 × 100 = 77.3%
How Sourdough Calculation Works
- 1Enter the total dough weight you want and desired hydration percentage.
- 2Set the starter percentage (typically 15-25% of flour weight).
- 3The calculator uses baker's math to give exact flour, water, starter, and salt amounts.
About Sourdough Calculator

Frequently Asked Questions
What hydration should I use?
65-70% is a good starting point for beginners. Higher hydration (75-85%) gives a more open crumb but is harder to handle.
What is baker's math?
All ingredients are expressed as a percentage of total flour weight. Flour is always 100%, and everything else is relative to it.
