TDEE Calculator
TDEE Calculator – Estimate Your Daily Calorie Requirements Accurately
The TDEE Calculator is a free online health and fitness tool that estimates your Total Daily Energy Expenditure (TDEE)—the total number of calories your body burns each day. By entering your weight, height, age, gender, and activity level, you can instantly determine your daily calorie needs for maintaining, losing, or gaining weight.
Understanding your TDEE is one of the most important steps in building an effective nutrition and fitness plan. Whether you're aiming for fat loss, muscle gain, or weight maintenance, knowing your daily calorie requirements helps you make informed dietary decisions.
What is TDEE?
TDEE (Total Daily Energy Expenditure) represents the total calories your body burns over an entire day. It includes calories used for basic body functions, digestion, daily movement, exercise, and other physical activities.
TDEE is calculated using your Basal Metabolic Rate (BMR) combined with an activity multiplier that reflects your lifestyle.
How Does the TDEE Calculator Work?
The calculator requires five simple inputs:
- Weight – Your body weight in kilograms.
- Height – Your height in centimeters.
- Age – Your current age.
- Gender – Male or Female.
- Activity Level – Your average daily physical activity.
Using these values, the calculator instantly estimates:
- Basal Metabolic Rate (BMR).
- Total Daily Energy Expenditure (TDEE).
- Calories burned through activity.
- Interactive calorie breakdown chart.
Formula Used
The calculator uses the widely accepted Mifflin-St Jeor Equation to estimate BMR.
Male BMR = (10 × Weight) + (6.25 × Height) − (5 × Age) + 5
Female BMR = (10 × Weight) + (6.25 × Height) − (5 × Age) − 161
After calculating BMR:
TDEE = BMR × Activity Factor
The activity multiplier depends on your selected lifestyle, ranging from sedentary to highly active.
How to Use This Calculator
- Enter your weight.
- Enter your height.
- Enter your age.

Example Calculation
Suppose you have the following details:
- Weight: 70 kg
- Height: 170 cm
- Age: 30 Years
- Gender: Male
- Activity Level: Moderately Active
The calculator estimates:
- BMR ≈ 1,618 kcal/day
- TDEE ≈ 2,500 kcal/day
