Net Carbs Calculator


About Net Carbs Calculator (Formula)

A Net Carbs Calculator is a tool commonly used in the context of low-carb diets, such as the ketogenic diet. It helps individuals determine the net carbohydrate content of a food item by subtracting the fiber and certain sugar alcohols from the total carbohydrate content. This calculation is important for managing carbohydrate intake and making informed dietary choices. The formula for calculating net carbs involves simple subtraction.

The formula for calculating net carbs is:

Net Carbs = Total Carbohydrates – Dietary Fiber – Sugar Alcohols


  • Net Carbs represent the amount of carbohydrates that have a significant impact on blood sugar levels.
  • Total Carbohydrates is the sum of all carbohydrates in the food item.
  • Dietary Fiber is a type of carbohydrate that is not fully digested and does not significantly affect blood sugar levels.
  • Sugar Alcohols are sweeteners that are partially absorbed and have a smaller impact on blood sugar compared to regular sugar.

Using the Net Carbs Calculator involves these steps:

  1. Input: Enter the values of total carbohydrates, dietary fiber, and sugar alcohols present in the food item.
  2. Calculation: The calculator subtracts the values of dietary fiber and sugar alcohols from the total carbohydrates to calculate the net carbs.
  3. Output: The calculator displays the calculated net carbs in the food item.

This tool is particularly useful for individuals following low-carb diets who want to monitor their carbohydrate intake while still enjoying a variety of foods. It allows them to focus on carbohydrates that have a significant impact on blood sugar levels, helping them manage their diet more effectively.

For example, if a food item has 20 grams of total carbohydrates, 5 grams of dietary fiber, and 2 grams of sugar alcohols, the Net Carbs Calculator will provide you with the net carbs, which is 13 grams.
