What Are Carbohydrates?
Carbohydrates (carbs) are one of the main macronutrients your body uses for energy. When you eat carbs, your body converts them into glucose, which fuels your muscles and brain.
There are two main types:
- Simple carbs (sugar, fruits)
- Complex carbs (rice, oats, potatoes)
How to Use the Carb Calculator

You’ll get your recommended daily carb intake in grams.
How Carbs Are Calculated
Carb intake is based on your total calorie intake and macronutrient split:
- Protein intake is set first
- Fat intake is calculated next
- Remaining calories come from carbohydrates
Carbs (g)=Calories−(Protein calories+Fat calories)4Carbs\ (g) = \frac{Calories – (Protein\ calories + Fat\ calories)}{4}
Since each gram of carbs = 4 calories.
