Carbohydrate Calculator
The Carbohydrate Calculator helps estimate how many grams of carbohydrate correspond to a selected daily calorie target and carbohydrate share. It can be useful when planning a macronutrient target.
Carbohydrate formula
Carbohydrates provide about 4 calories per gram. When a calorie target and carbohydrate percentage are known, carbohydrate grams = daily calories Γ carbohydrate percentage Γ· 4.
Using the calculator
Enter the values requested by the calculator and check that a percentage is entered as a percentage rather than as a whole-number calorie value. Calculate the result to see the estimated grams of carbohydrate.
Putting the number in context
Carbohydrate requirements vary with activity, overall diet, goals, and individual circumstances. The calculated value is a planning estimate rather than a universal requirement.
