Calorie Calculator: The Ultimate Guide to Daily Calorie Needs

The Calorie Calculator helps you estimate how many calories your body needs each day to maintain, lose, or gain weight. Based on your age, gender, height, weight, activity level, and fitness goal, it provides accurate daily calorie targets and macronutrient breakdowns for smarter diet planning.

What is a Calorie Calculator?

A calorie calculator determines how much energy your body burns daily. It combines your Basal Metabolic Rate (BMR) — calories burned at rest — with your Total Daily Energy Expenditure (TDEE), which includes physical activity.

How It Works

1️⃣ The calculator first computes your BMR using the Mifflin-St Jeor formula.
2️⃣ Then, it multiplies your BMR by your activity level to find your TDEE.
3️⃣ Finally, it adjusts calories based on your goal: subtract for weight loss, add for weight gain.

Macronutrient Distribution

• Protein: 30% of total calories
• Carbohydrates: 50%
• Fats: 20%

Why Track Calories?

• Understand your body's true energy needs.
• Plan meals that support your fitness goals.
• Balance your macronutrients effectively.
• Monitor progress and make adjustments easily.
