Daily Calorie & Macro Target
- 1Enter your Daily Calorie Goal (kcal).
- 2Select a macro ratio preset (Balanced 30/40/30, High Protein 40/30/30, Low Carb 35/20/45) or customize percentage split.
- 3View your target daily intake in grams for Protein, Carbohydrates, and Fat.
Macronutrients are the main energy-providing nutrients required by the body: Protein, Carbohydrates, and Fat. Distributing calorie targets into optimal macro ratios supports muscle preservation, energy, and hormonal health.
Essential for muscle repair and tissue synthesis.
Protein Grams = (Total Calories × Protein %) / 4Primary energy source for brain function and workout performance.
Carb Grams = (Total Calories × Carb %) / 4Crucial for hormone production, joint health, and nutrient absorption.
Fat Grams = (Total Calories × Fat %) / 9Protein = (2000×0.30)/4 = 150g | Carbs = (2000×0.40)/4 = 200g | Fat = (2000×0.30)/9 = 67gCarbs = 2000×0.40/4 = 200 g; Protein = 2000×0.30/4 = 150 g; Fat = 2000×0.30/9 ≈ 66.7 gCarbs = 2500×0.05/4 ≈ 31.3 g; Protein = 2500×0.25/4 ≈ 156.3 g; Fat = 2500×0.70/9 ≈ 194.4 g- Must Sum to 100%: Your macro percentage allocations (Protein % + Carb % + Fat %) must equal exactly 100%.
- Calorie Density Difference: Fat provides more than twice the calories per gram (9 kcal/g) compared to protein and carbs (4 kcal/g).
- Adjust to Training Goals: High protein ratios (35-40%) support muscle retention during caloric deficits.
How many calories are in a gram of protein, carb, and fat?
Protein and Carbohydrates contain 4 calories per gram. Dietary Fat contains 9 calories per gram.
Which macro ratio is best for muscle gain or loss?
Higher protein splits (30-40%) help preserve lean muscle during fat loss or build tissue during surplus. Balanced 30/40/30 works well for general fitness.
Why must the three percentages add up to 100%?
The split divides your calories among protein, carbs, and fat with nothing left over. The calculator requires the sum to be within 0.1 of 100% and otherwise returns no result.
What energy values per gram does it use?
4 kcal per gram of protein, 4 kcal per gram of carbohydrate, and 9 kcal per gram of fat.
