TDEE Calculator

About the TDEE Calculator

Total Daily Energy Expenditure (TDEE) is the complete picture of your daily calorie burn — your BMR multiplied by your activity level. While BMR tells you what your body needs at rest, TDEE tells you exactly how many calories you burn in a typical day given your lifestyle. It is the single most important number for anyone managing their weight, because eating at your TDEE maintains weight, below it loses weight, and above it gains weight.

How It Works

TDEE = BMR × Activity Multiplier. Activity multipliers: Sedentary (desk job, little exercise) = 1.2; Lightly active (light exercise 1-3 days/week) = 1.375; Moderately active (moderate exercise 3-5 days/week) = 1.55; Very active (hard exercise 6-7 days/week) = 1.725; Extremely active (physical job + twice daily training) = 1.9. A person with a BMR of 1,800 who exercises moderately has a TDEE of 1,800 × 1.55 = 2,790 calories/day.

Tips & Best Practices

• ✓Most people overestimate their activity level — when in doubt, choose the lower multiplier.
• ✓A 500-calorie daily deficit from TDEE creates approximately 1 lb of fat loss per week.
• ✓TDEE increases on heavy training days and decreases on rest days — some use an average.
• ✓Non-exercise activity thermogenesis (NEAT) — fidgeting, walking, standing — can vary by 2,000 calories between individuals.
• ✓Recalculate TDEE every 4-6 weeks as your weight and fitness level change.

Who Uses This Calculator

Athletes optimizing performance nutrition, people on cutting or bulking cycles, and anyone who has hit a weight loss plateau use TDEE to precisely calibrate their calorie intake. Personal trainers use TDEE to design client nutrition programs.
