Why this Sourdough Feeding Timeframe Calculator is so helpful:

Timing your sourdough starter’s peak is one of the biggest challenges in baking. If you feed it too early or too late, it might not be at its strongest when you need it for baking. This calculator takes the guesswork out of the process by letting you choose when you want your starter to be ready, and it automatically selects the best feeding ratio for you. Whether you need your starter to peak in just a few hours or want a slower, overnight rise, this tool ensures that you get the right balance of starter, flour, and water every time. Perfect for bakers who want more control over their schedule without having to memorize complicated ratios!

How to Use This Calculator

1️⃣ Enter your total starter amount in grams. This is how much starter you want to maintain or use in your next bake.

​

2️⃣ Select your desired timeframe for when you want your starter to peak:

• 4-6 hours → Uses a 1:1:1 ratio (fastest peak)

• 6-8 hours → Uses a 1:2:2 ratio

• 10-12 hours → Uses a 1:3:3 ratio

• 12-14 hours → Uses a 1:5:5 ratio

• 16-24 hours → Uses a 1:10:10 ratio (slowest fermentation, ideal for overnight feedings)

​

3️⃣ Click "Calculate" to get the exact amounts of starter, flour, and water you need to feed your starter properly.

​

4️⃣ Use the results to mix your starter with fresh flour and water, then let it ferment until it's bubbly and active—ready for your next bake!
