Feed your sourdough starter with the right amounts every time by working from a feeding ratio. A ratio written as starter to flour to water, such as 1:2:2 or 1:5:5, tells you how much fresh flour and water to add relative to the starter you keep. Enter how much existing starter you want to carry forward and your ratio, and this calculator returns the grams of flour and water to add and the total weight after feeding. A lower ratio like 1:1:1 ripens fast and suits same day baking, while a higher ratio like 1:5:5 slows fermentation for an overnight rise or fridge storage. It also shows the resulting hydration if flour and water differ. These are standard feeding maths used by bread bakers. Everything is computed locally in your browser.
A ratio like 1 to 2 to 2 means one part starter, two parts flour and two parts water by weight, and the tool scales it to your starter amount.
It gives grams of starter, flour and water for the feed based on your ratio and the starter weight you enter.
Feeding by ratio keeps the balance of old starter to fresh flour and water consistent, which controls how fast the starter ripens.
