⚠️ TDEE is an estimate based on population averages. Your actual expenditure may vary. Adjust based on real results over 2–4 weeks.

What is TDEE?

Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day, accounting for your basal metabolic rate (BMR) plus all physical activity. It's calculated by multiplying your BMR by an activity factor ranging from 1.2 (sedentary) to 1.9 (extremely active).

TDEE is your maintenance calorie level — eating at TDEE keeps your weight stable. Eating below TDEE creates a deficit (weight loss), while eating above creates a surplus (weight gain).

Activity levels explained

  • Sedentary (×1.2): Desk job, no structured exercise, minimal walking.
  • Lightly active (×1.375): 1–3 workout sessions per week, or a job with light movement.
  • Moderately active (×1.55): 3–5 sessions per week at moderate intensity.
  • Very active (×1.725): Hard training 6–7 days per week, or a physically demanding job.
  • Extra active (×1.9): Twice-daily training, athlete in competition period, or very heavy manual labor.

When to Use a TDEE Calculator

Use your TDEE (Total Daily Energy Expenditure) to set a calorie target for weight loss (eat 300–500 kcal below TDEE), weight gain (eat 200–300 kcal above TDEE), or maintenance. It accounts for your basal metabolic rate (BMR) plus activity level. TDEE is more accurate than generic 2,000 kcal recommendations because it's personalized to your weight, height, age, sex, and lifestyle. Pair it with a BMR Calculator, Calorie Deficit Calculator, Protein Intake Calculator, or Macro Calculator for a complete nutrition plan.

Activity Multipliers Explained

TDEE = BMR × Activity Multiplier. Common multipliers (Mifflin-St Jeor equation):

  • Sedentary (desk job, no exercise): × 1.2
  • Lightly active (1–3 days/week exercise): × 1.375
  • Moderately active (3–5 days/week): × 1.55
  • Very active (6–7 days/week hard exercise): × 1.725
  • Extra active (physical job + hard training): × 1.9

Most people overestimate their activity level by one category. If weight isn't changing as expected, try the next lower multiplier. TDEE is an estimate — track food and adjust by 100–200 kcal based on real-world results over 2–3 weeks.

Frequently Asked Questions

What is TDEE and how is it calculated?
TDEE (Total Daily Energy Expenditure) is the total calories you burn per day. It's calculated by multiplying your BMR (Basal Metabolic Rate, using Mifflin-St Jeor) by an activity factor: 1.2 for sedentary, 1.375 light, 1.55 moderate, 1.725 very active, 1.9 extra active.
How do I use TDEE to lose weight?
Eat 300–500 kcal below your TDEE per day for gradual fat loss (about 0.3–0.5 kg per week). Avoid going more than 1,000 kcal below TDEE, as aggressive deficits increase muscle loss risk and metabolic adaptation. Recheck your TDEE every 4–6 weeks as weight changes.
Which activity level should I choose?
Most people overestimate their activity level. If you work a desk job and go to the gym 3 times a week, choose 'Lightly active' (1.375) to 'Moderately active' (1.55). Start conservative and adjust based on real results after 2–4 weeks — if weight isn't changing, adjust calories accordingly.
What activity level should I choose?
Sedentary = desk job, little to no exercise. Lightly active = 1–3 days/week exercise. Moderately active = 3–5 days/week. Very active = 6–7 days/week intense exercise. Extra active = physical job + daily training. When in doubt, choose one level lower than you think.
How accurate is a TDEE estimate?
TDEE calculators have a margin of error of ±100–300 kcal/day compared to gold-standard methods like doubly-labeled water. Use the result as a starting point, track your weight for 2–3 weeks, and adjust by ±100–200 kcal based on actual results.
How accurate is a TDEE calculator?
TDEE calculators are estimates with a ±10–15% margin of error. Factors that affect accuracy include muscle mass (more muscle = higher BMR), hormonal status, sleep quality, and non-exercise activity thermogenesis (NEAT — fidgeting, walking, standing). Use TDEE as a starting point, then track your actual intake and weight change over 2–3 weeks and adjust by 100–200 kcal.
What is the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the calories your body burns at complete rest — just to maintain basic functions like breathing, circulation, and cell repair. TDEE adds the calories burned through all physical activity (exercise + NEAT). BMR is typically 60–70% of TDEE for sedentary individuals and 50–55% for very active people.
