Sourdough Calorie Calculator โ€“ Estimate Calories per Loaf

Estimate calories for your sourdough recipe by entering ingredient weights. Includes guidance on common ingredients and adjustments.

What is this?

This calculator converts ingredient weights into estimated calories for an entire dough and per serving. It uses standard calorie values for common baking ingredients and adjusts for total dough weight to provide per-slice estimates.

Why important: Knowing calories helps portion control and recipe adjustment. Accurate calorie estimates require precise weights for each ingredient and an understanding that baking changes moisture (so cooked-loaf weight differs from raw dough weight) [1][2].

Calculator

Estimated total calories (raw dough) --

Uses: Bread flour ~364 kcal/100g, Rye flour ~345 kcal/100g, Starter ~182 kcal/100g (50% flour). Add-ins: based on selected ingredient

Estimated baked loaf weight (g) --

Assumes ~8% moisture loss during baking; adjust with measured bake losses for accuracy [1][2]

Calories per serving --

Divides total estimated calories by number of slices

Recommendations by Flour Type

Hydration Ranges

Low-calorie (per slice) n/a

Simple white or rye sourdough with minimal add-ins

Moderate-calorie (per slice) n/a

Includes seeds or olive oil; moderate add-ins increase calories noticeably

High-calorie (per slice) n/a

Contains butter, oil, honey, nuts โ€” expect significant calorie increase

Tips

๐Ÿ’ก Weigh ingredients precisely

Weigh all ingredients on a kitchen scale. Volume measures are too imprecise for calorie estimates; minor weight differences change totals noticeably [1].

๐Ÿ’ก Include starter composition

Starter contributes flour and water โ€” and therefore calories. Add the flour-equivalent from your starter to your flour totals when calculating calories [2].

๐Ÿ’ก Adjust for bake loss

Measure your typical moisture loss (weigh raw dough and baked loaf). This calculator uses ~8% loss by default; adjusting with your measured loss improves per-slice accuracy [1][2].

๐Ÿ’ก Account for dense vs open crumb

Open-crumb loaves retain less water and can weigh less per slice; denser loaves weigh more and therefore have more calories per slice even with the same recipe [1].

๐Ÿ’ก Use proper tools for portioning

Divide and weigh portions with a dough scraper and scale for consistent serving sizes.
