Accurate Macro Calculator
Determine your precise daily protein, carbohydrate, and fat requirements for optimal health, weight loss, or muscle gain.
How to Use the Macro Calculator
- Enter your age, gender, weight in kilograms, and height in centimeters.
- Select your daily physical activity level from the dropdown menu.
- Choose your primary fitness goal: lose weight, maintain, or build muscle.
- Select your preferred diet split (Balanced, Low Carb, or High Carb).

Key Features
Instant Results
Calculates your Total Daily Energy Expenditure (TDEE) and macro split in milliseconds natively on your device.
Clinically Proven Formula
Uses the Mifflin-St Jeor equation, recognized by dietitians as the most accurate model for resting metabolic rate.
Custom Goals
Built-in calorie buffers for safe weight loss (deficit) or effective muscle gain (surplus).
Flexible Diet Splits
Choose between balanced distributions, low-carb options, or high-carb athletic setups.
100% Privacy
Your health data never leaves your browser. All processing is strictly local and completely secure.
Mobile Friendly
Designed perfectly for tracking adjustments on the go from your smartphone or tablet.
How the Math Works
This tool combines your Basal Metabolic Rate (BMR) with your physical activity levels to find your daily energy needs. We use the Mifflin-St Jeor Equation:
Women: (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) - 161
After finding the BMR, it is multiplied by your Activity Factor (1.2 to 1.9) to get your TDEE (Total Daily Energy Expenditure). Depending on your selected goal, 500 calories are added (surplus) or subtracted (deficit). Finally, that target calorie number is divided into protein (4 kcal/g), carbohydrates (4 kcal/g), and fats (9 kcal/g) based on the chosen diet split.

What is a Macro Calculator?
A Macro Calculator is a specialized digital tool designed to help you determine exactly how many grams of macronutrients (protein, carbohydrates, and dietary fat) you need to consume daily. Rather than just focusing on total calories, tracking macros ensures your body composition changes appropriately—losing fat rather than muscle, or gaining muscle rather than excess fat.
Whether you follow a traditional Indian diet rich in carbohydrates, or a Western diet leaning heavily on proteins and fats, balancing these three pillars is the foundation of scientific nutrition. By manipulating these variables, you take complete control over your metabolism and recovery.

Is this tool free to use?
Yes, our Macro Calculator is completely free to use without any limits or hidden fees.
How accurate is this macro calculator?
It uses the clinically validated Mifflin-St Jeor equation, which is widely considered the most accurate formula for estimating basal metabolic rate.
Should I weigh my food raw or cooked?
Always try to weigh your food raw before cooking, as cooking methods can change the water weight and alter the accuracy of your tracking.
What if I miss my macros by a few grams?
Do not stress over small deviations. Being within 5 to 10 grams of your target for each macronutrient is perfectly fine for long-term progress.
How often should I recalculate my macros?
It is best to recalculate your macros every time your body weight changes by 2-3 kilograms, or if you change your primary fitness goal.
Why are protein targets important?
Protein is essential for muscle repair, growth, and overall bodily functions. It also provides the highest satiety of all macronutrients, keeping you full longer.
Can I eat any carbs to hit my targets?
Technically yes for body composition, but for overall health and energy levels, you should aim to get most of your carbs from whole, unprocessed sources like oats, rice, and potatoes.
What is considered a "Balanced" split?
A balanced split generally refers to taking 30% of your calories from protein, 35% from carbs, and 35% from fats. It is a great starting point for most people.
