Plan daily macro grams from calorie and ratio targets.
Overview
Macronutrient planning assigns calories across protein, carbohydrates, and fats to support body composition, recovery, and performance goals.
A macro calculator converts percentage splits into gram targets using energy densities: protein and carbs at 4 kcal/g, fats at 9 kcal/g. This makes meal planning more actionable.
Macro targets are starting points and should be adjusted based on progress, hunger, training load, and lifestyle adherence.
Steps
Enter maintenance, deficit, or surplus calorie target.
Select percentage distribution for protein, carbs, and fat.
Tool converts each calorie share into grams.
Ensure macro percentages sum to 100 percent.
Refine targets based on weekly progress trends.
Math
Protein g = (Calories x Protein%)/4; Carb g = (Calories x Carb%)/4; Fat g = (Calories x Fat%)/9
Each macro has a known calorie density. Dividing allocated macro calories by its kcal-per-gram value yields daily gram targets.
Worked cases
Protein 180 g, Carbs 240 g, Fat 80 g
Daily macro plan = 180P / 240C / 80F.
Protein 190 g, Carbs 143 g, Fat 63 g
Plan favors satiety and lean-mass retention support.
Protein 175 g, Carbs 385 g, Fat 62 g
Higher carbs support sustained training output.
