TDEE Calculator

How the TDEE Calculator Works

TDEE = BMR × Activity Multiplier (1.2 for sedentary to 1.9 for very active)

This tool calculates the total calories your body burns daily by multiplying your Basal Metabolic Rate (BMR) by your physical activity factor. This number is the foundation for any diet plan, whether for weight loss or gain.

  1. 1

    Calculate BMR

    The tool calculates your basal metabolic rate from your weight, height, and age

  2. 2

    Determine Activity

    Select your daily and weekly physical activity level

  3. 3

    Calculate TDEE

    BMR is multiplied by the activity factor to get total daily burn

Use Cases

Weight Loss Diet Planning

Determine the calorie deficit needed for weight loss

Muscle Building Programs

Know the calorie surplus needed for muscle building

Weight Maintenance

Know the calories needed to maintain your current weight

Tips

  • 1

    Recalculate TDEE every 4-6 weeks as your weight changes

  • 2

    Be honest when assessing your activity level

  • 3

    Most people overestimate their physical activity

  • 4

    Start with a lower activity level and adjust based on results

Common Mistakes

  • Overestimating physical activity level

  • Not updating calculations after weight loss or gain

  • Ignoring non-exercise daily activity (walking, housework)

  • Relying on one number without adjusting based on actual results

FAQs

What's the difference between BMR and TDEE?

BMR is calories burned at complete rest, while TDEE includes all daily activities.

How much should I reduce from TDEE to lose weight?

A 500 calorie daily deficit leads to about 0.5 kg loss per week.

Is TDEE constant?

No, it changes with weight, age, activity level, and muscle mass.
