Calculate the net carbs of any food. Enter the total carbs, fiber, and sugar alcohol and this calculator will estimate the net carbs in your food. This calculator can also determine the amount of fiber or sugar alcohol given the net carbs and two of the other variables.

Net Carbs Formula

Determining the net carbs is quite simple, and follows an easy formula.

Net Carbs = Total Carbs – Fiber – Sugar Alcohols.

To calculate net carbs, subtract the grams of fiber and grams of sugar alcohols from the total grams of carbs.

How to Calculate Net Carbs

Calculating net carbohydrates is a key process in many modern diets, including the Atkins and keto diets. That is because net carbs are the carbohydrates that your body can digest, and affect your body’s functions.

What’s the point of calculating net carbs?

Well, there could be several reasons. One, you could be on either a Ketogenic diet (also known as KETO) or an Atkins type of diet, where you are required to stay below a certain number of carbs per day. Two, you could be an athlete that tracks your macros. (Macros is short for macronutrients which consist of Fats/Carbs/proteins.) Three, you could have some type of diabetes where it’s important to watch your blood sugar levels. Or maybe you are just a health nerd that likes to track your good. 

Whatever the reason, the point of tracking net carbs as opposed to total carbs is that your body can’t break down fiber or sugar alcohols. This means that these carbs will not provide you with any calories and will not significantly affect your blood sugar levels. In essence, they go in one hole and out the other without providing nutrients. 

That’s not to say fiber isn’t important. Most people know that proper fiber intake is a key to a well-functioning bowel movements. In fact, it’s because they cannot be digested that they help with bowel movements. Your body cannot get nutrients from it, so it tries to force it out of the body, along with whatever it’s mixed but with. 

One last note on Net Carbs, specifically sugar alcohols. Sugar alcohols, or artificial sweeteners, do not significantly affect blood sugar or provide calories, but that doesn’t mean they have no effect on the body. There have been several recent studies that suggest they may have more negative impacts on the body. We suggest you do your own research.
