Calculators
Calculate your daily macronutrient targets (protein, carbohydrates, and fat) based on your calorie goal and body composition objectives. Supports cutting, maintenance, and bulking presets.
Follow these simple steps to get instant, accurate results directly in your browser:
Input your daily calorie budget (from the Calorie Calculator) or current intake.
Choose your primary goal: Fat Loss (High Protein), Maintenance, Muscle Gain, or Keto.
Inspect your daily targets for protein (g), carbs (g), and healthy fats (g).
The Macro Calculator calculates your optimal daily macronutrient distribution—protein, carbohydrates, and fats—based on your body weight, calorie target, and fitness objectives.
While total calories dictate weight gain or loss, the distribution of macronutrients dictates body composition (muscle retention versus fat loss), athletic endurance, and hormonal health. The tool calculates grams and percentage ratios adhering to the Acceptable Macronutrient Distribution Ranges (AMDR) established by the National Academy of Medicine.
Calculations run in client-side memory, allowing you to fine-tune high-protein, balanced, or low-carb/keto dietary splits in complete privacy.
Protein = 4 kcal/g | Carbohydrates = 4 kcal/g | Fats = 9 kcal/g
Grams = (Total Daily Calories * Macro %) / Energy DensityCalculates required grams by dividing category calorie allocations by the caloric density per gram.
Daily Target = 2,000 kcal | Balanced Split: 30% Protein, 40% Carbs, 30% Fat Protein: (2,000 * 0.30) / 4 = 600 kcal / 4 = 150g protein/day Carbs: (2,000 * 0.40) / 4 = 800 kcal / 4 = 200g carbs/day Fats: (2,000 * 0.30) / 9 = 600 kcal / 9 = 66.7g fats/day.
Our calculation methodologies adhere to published guidelines from authoritative government agencies and standards bodies:
Displays macronutrient breakdown both in total daily grams and percentage of caloric intake.
Scales protein recommendations based on body mass and athletic training intensity.
Includes Balanced (40/30/30), High Protein (40/40/20), and Low Carb (20/45/35) splits.
Runs in-memory with zero data transmission.
Target 0.8–1.0 grams of protein per pound of body weight during calorie deficits.
Structure high-carbohydrate macro splits (55–65% carbs) for marathon and cycling training.
Calculate strict low-carb parameters (<50g net carbs) with elevated healthy fat proportions.
