How to calculate
Split a daily calorie target into carbohydrate, protein and fat grams.
Carbohydrate = calories*carb/100/4; Protein = calories*protein/100/4; Fat = calories*fat/100/9
Worked example
Daily calories: 2200; Carbohydrate share (%): 45; Protein share (%): 25; Fat share (%): 30.
Carbohydrate: 247.5 g; Protein: 137.5 g; Fat: 73.33 g.
Assumptions and limits
The percentages should total 100. Individual needs can differ with health, sport and clinical goals.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Split a daily calorie target into carbohydrate, protein and fat grams. The displayed figures use the inputs and formula shown on this page.
