What is Macro Calculator?

▾

Macronutrients (macros) are the three main energy-providing nutrients: protein, carbohydrates, and fat. Tracking macros gives more control over body composition than simply counting calories, as each macro serves different physiological roles.

सूत्र

f(x)Grams = (Calories × percentage) ÷ calories per gram

How to Macro Calculator

▾

1Protein: 4 kcal per gram — builds and repairs muscle, satiety
2Fat: 9 kcal per gram — hormones, fat-soluble vitamins, brain function
3Carbohydrates: 4 kcal per gram — primary energy source, especially for exercise
4Grams = (Calories × percentage) ÷ calories per gram

Worked Examples

▾

Example 1

Given:2000 kcal, fat loss goal (35/30/35 P/F/C)

परिणाम:Protein: 175g · Fat: 67g · Carbs: 175g

Example 2

Given:3000 kcal, muscle gain (25/25/50 P/F/C)

परिणाम:Protein: 188g · Fat: 83g · Carbs: 375g

Macro Split Guidelines by Goal

▾

Goal	Protein	Fat	Carbs	Notes
Fat loss	30–40%	25–35%	25–40%	High protein preserves muscle
Maintenance	20–30%	25–35%	40–55%	Flexible, sustainable
Muscle gain	25–30%	20–30%	45–55%	Carbs fuel training
Ketogenic	20–30%	60–75%	5–10%	Special metabolic state
Endurance athlete	15–20%	20–30%	55–65%	High carb for glycogen

Frequently Asked Questions

▾

What is Macro?

Macronutrients (macros) are the three main nutrients that provide energy: protein (4 kcal/g), carbohydrates (4 kcal/g), and fat (9 kcal/g). Calculating your optimal macro split helps optimise body composition — whether losing fat, maintaining weight, or building muscle

Pro Tip

Fibre-rich carbohydrates (vegetables, legumes, whole grains) slow digestion and blunt blood sugar spikes, helping you feel fuller on fewer calories.

⭐

Did you know?

Fat has more than twice the calories per gram as protein or carbs (9 vs 4 kcal/g), which is why high-fat foods are so energy-dense.
