Starter Feeding Calculator

Build a feeding formula by flour amount or final starter weight, using familiar ratios with hydration, inoculation, and jar rise in view.

Build Mode
Feeding Ratio

Ratio means starter : flour : water. This is the way most bakers describe a feeding.

Starter Type
Advanced Options
Starter Hydration

Use this if your starter is kept at a hydration other than 100% or 50%. Enter the percentage and it will be reflected in your water calculation.

Use inoculation percentage instead

Inoculation is the amount of mature starter compared to the new flour. Lower percentages slow the build; higher percentages speed it up.

Equivalent inoculation: 25%

Equivalent ratio: 1:4:4

75°F

Balanced build. Good everyday feeding range.
