Total carb / servings + net carbs (carbs − fiber). Critical for keto, diabetes management.

Inputs

Erythritol, xylitol — half-counted on most labels.

Step-by-step

  1. Per serving total = 280 / 4 = 70.0 g.
  2. Net = total − fiber − ½ sugar alcohols = 70.0 − 8.0 − 0.0 = 62.0 g.
  3. Keto target: net carbs <20-25g/day total.

How to use this calculator

  • Sum total carbs and fiber from ingredients.
  • Add sugar alcohols if applicable.
  • Set servings.
  • Read total + net per serving.

About this calculator

Total carbs vs. net carbs: total = all carbohydrates including fiber. Net = total minus fiber minus half of sugar alcohols (FDA convention used by keto trackers). Strict keto: <20-25g net carbs/day. Lazy keto: <50g. Standard low-carb: <100g. The FDA Daily Value reference is 275g/day on a 2,000 kcal diet (55% of calories from carbs). For diabetics, dividing carbs evenly across meals (45-60g/meal) helps blood-sugar control.

Frequently asked

Fiber isn't absorbed/metabolized like sugar/starch — it doesn't spike blood sugar. Net carbs better reflects glycemic load.
