Carbohydrate Calculator

Estimate daily carb grams based on age, gender, height, weight, activity, and goal.

Formula & Methodology

Daily carbs (g) = (target calorie share for carbs × daily calories) / 4, since carbs provide 4 calories per gram.

Worked Example

On 2,000 calories with 50% from carbs, you need about 250 grams of carbohydrates per day.
