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.
Three Carb Levels
Low carb (25%), moderate (50%), and high carb (60%) presets based on common dietary approaches.
Per-Meal Breakdown
See how many grams per meal whether you eat 3, 4, or 5 meals a day.
TDEE-Based
Uses Mifflin-St Jeor and activity multipliers for an accurate caloric baseline.
