Use this clinical TDEE calculator to find your Total Daily Energy Expenditure—the exact number of calories your body burns in a 24-hour period across rest, work, workouts, and digestion. Whether your goal is sustainable fat loss (a 500-calorie deficit), body recomposition, or lean muscle gain, knowing your true maintenance calories is the foundation of every nutrition plan.

TDEE = BMR × Physical Activity Level (PAL) Multiplier. Resting BMR is calculated via Mifflin-St Jeor or Katch-McArdle (using Lean Body Mass). Activity multipliers range from 1.2 (sedentary desk work) up to 1.9 (heavy athletic training twice daily), accounting for Non-Exercise Activity Thermogenesis (NEAT), Exercise Activity Thermogenesis (EAT), and the Thermic Effect of Food (TEF ~10%).
Total Daily Energy Expenditure (TDEE) is not a single static rate—it is the sum of four distinct metabolic engines operating inside your body every day:
Our TDEE calculator supports the three gold-standard clinical equations recognized by the Academy of Nutrition and Dietetics (AND) and the American College of Sports Medicine (ACSM).
| Activity Tier | Multiplier | Daily Step Count (Approx.) | Real-World Lifestyle & Workout Profile |
|---|---|---|---|
| Sedentary | BMR × 1.2 | Under 4,000 steps | Desk or remote job, driving commute, minimal planned exercise. |
| Lightly Active | BMR × 1.375 | 4,000 – 7,000 steps | Light exercise 1–3 days/week OR desk worker walking 30 mins daily. |
| Moderately Active | BMR × 1.55 | 7,000 – 10,000 steps | Lifting weights or cardio 3–5 days/week, or active on-feet retail/teaching job. |
| Very Active | BMR × 1.725 | 10,000 – 14,000 steps | Hard training 6–7 days/week OR physically demanding job + gym sessions. |
| Extra Active (Athlete) | BMR × 1.9 | 15,000+ steps | Heavy manual labor (construction/farming) or competitive 2x/day athletic training. |
(10 × 81.65) + (6.25 × 177.8) - (5 × 30) + 5 = 1,783 kcal/day. If he lifts weights 4 days a week (Moderately Active, 1.55), his TDEE is 1,783 × 1.55 = 2,763 kcal/day.Once you have your maintenance TDEE, adjust your daily calorie target based on your body composition goal:
| Fitness Goal | Daily Calorie Target | Expected Weekly Rate | Recommended Protein Target |
|---|---|---|---|
| Sustainable Fat Loss (Standard Cut) | TDEE - 500 kcal | Lose ~1.0 lb / week | 0.8 to 1.0 g per lb of body weight |
| Gentle Fat Loss / Mini-Cut | TDEE - 250 to 300 kcal | Lose ~0.5 lb / week | 0.8 to 1.0 g per lb of body weight |
| Body Recomposition (Lose Fat, Build Muscle) | TDEE - 100 to Maintenance | Weight stable; waist shrinks | 1.0 to 1.1 g per lb of body weight |
| Lean Muscle Bulk (Clean Surplus) | TDEE + 250 to 350 kcal | Gain ~0.5 lb / week | 0.8 to 1.0 g per lb of body weight |
Clinical Safety Note: The NIH and clinical dietitians recommend keeping daily intake above 1,200 kcal/day for women and 1,500 kcal/day for men unless supervised by a physician, to prevent lean muscle catabolism and micronutrient deficiencies.
BMR (Basal Metabolic Rate) is the minimum number of calories your body burns at complete rest just to keep vital organs functioning. TDEE (Total Daily Energy Expenditure) is your BMR plus all the calories you burn moving, working, exercising, and digesting food throughout the day. You should never eat below your BMR for extended periods without clinical supervision.
Choose Lightly Active (1.375) or Moderately Active (1.55). Because traditional weightlifting burns relatively few calories per hour (roughly 180 to 300 kcal) compared to 8 hours of sitting, desk workers who lift weights 3 to 4 days per week without getting 8,000+ daily steps usually find 1.375 to 1.45 reflects their real-world maintenance best.
Subtract 300 to 500 calories from your TDEE (a 15% to 20% calorie deficit). Because one pound of adipose body fat stores roughly 3,500 calories, a 500-calorie daily deficit creates a 3,500-calorie weekly deficit—resulting in roughly 1 pound of fat loss per week while preserving muscle mass.
Three common reasons: (1) choosing an activity multiplier one tier too high (fitness watches routinely overestimate exercise burn by 20% to 30%), (2) under-tracking liquid calories, cooking oils, and weekend meals, or (3) metabolic adaptation after months of dieting. Drop your daily target by 150 to 200 calories or add 3,000 daily walking steps and track your weekly average scale weight for 14 days.
Yes. A lighter body requires less energy to move and maintain, and prolonged dieting triggers adaptive thermogenesis (subconscious reductions in NEAT and resting expenditure). Recalculate your TDEE after every 10 to 15 pounds (4.5 to 7 kg) of weight lost.
For 85% of adults who do not know their exact body fat percentage, the Mifflin-St Jeor equation is clinically proven to be the most accurate (within 10% of indirect calorimetry). However, if you are relatively lean, muscular, and know your body fat percentage via DEXA or Navy tape test, Katch-McArdle is superior because it accounts for the higher metabolic demand of skeletal muscle.
