Find your optimal daily carbohydrate intake.
This calculator estimates how many grams of carbohydrates you should eat each day based on your total calorie needs and preferred carb level. It first calculates your TDEE using the Mifflin-St Jeor equation and then applies your chosen carbohydrate percentage — low (25%), moderate (50%), or high (60%) — to give you a clear daily gram target.
