Quick Answer & Understanding Your Result
To calculate your Total Daily Energy Expenditure (TDEE), you must first determine your Basal Metabolic Rate (BMR) and multiply it by your specific daily physical activity factor (TDEE = BMR × Activity Multiplier).
Activity Multipliers Breakdown
- Sedentary (Desk Job / Little Exercise): BMR × 1.2
- Lightly Active (Light Exercise 1–3 days/week): BMR × 1.375
- Moderately Active (Moderate Exercise 3–5 days/week): BMR × 1.55
- Very Active (Intense Exercise 6–7 days/week): BMR × 1.725
- Extremely Active (Athletes / Heavy Physical Labor): BMR × 1.9
Applying TDEE for Body Goals
- Weight Loss (Cutting): Consume TDEE - 500 kcal/day to lose approximately 0.5 kg (1 lb) of body fat per week.
- Maintenance: Consume 100% of TDEE to stabilize current body weight.
- Muscle Gain (Bulking): Consume TDEE + 300 to 500 kcal/day alongside progressive resistance training.
Select your activity level and enter your physical metrics above to find your exact daily maintenance calories.
Formula & Calculation Logic
Mathematical FormulaBMR is computed via Mifflin-St Jeor and scaled by the physical activity coefficient.

Worked Examples Table
| Example | Input Values | Calculated Result | Explanation |
|---|---|---|---|
| Moderately Active Male (BMR 1,700 kcal) | 1,700 × 1.55 = 2,635 kcal maintenance. | ||
| Sedentary Female (BMR 1,300 kcal) | 1,300 × 1.2 = 1,560 kcal maintenance. |
