Calorie Calculator

What is a Calorie Calculator?

Calorie Calculator is a tool that determines your daily calorie needs. Calories are the amount of energy your body needs, which depends on your weight, height, age, and activity level.

It is usually calculated based on the BMR (Basal Metabolic Rate) and TDEE (Total Daily Energy Expenditure) formulas.

• BMR: This is your body's basic calorie needs, which are needed just to maintain breathing, blood circulation, and other basic functions.
• TDEE: Adding your daily activity level to BMR gives you total calorie needs.

Our calculator does all these calculations automatically, so you don't have to do any complicated calculations. It shows you accurate and fast results, which is helpful in weight loss, weight gain and maintenance planning.

Calorie Calculator Formulas Explained

Our calculator determines daily calorie needs based on the BMR and TDEE formulas . It automatically gives results based on the user's weight, height, age, and activity level.

Basal Metabolic Rate (BMR)

BMR is the calories your body needs just to maintain basic functions—such as breathing, blood circulation, and cellular activity.

• Mifflin-St Jeor Equation:
  
  
• Men: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age in years) + 5
• Women: BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age in years) − 161

Total Daily Energy Expenditure (TDEE)

TDEE is the total daily calorie requirement, which is determined by adding activity level to BMR.

• Activity Multipliers:
  
  
• Sedentary (little or no exercise) → BMR × 1.2
• Lightly active (light exercise 1–3 days/week) → BMR × 1.375
• Moderately active (moderate exercise 3–5 days/week) → BMR × 1.55
• Very active (heavy exercise 6–7 days/week) → BMR × 1.725
• Super active (excessive physical activity) → BMR × 1.9

Calorie Adjustments for Goals

• Weight Loss: Healthy weight loss can be achieved by reducing about 500 kcal per day.
• Weight Gain: It is possible to gain healthy weight by increasing your daily intake by about 500 kcal.
