|---|---|---|
| Sedentary | Little or no 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 daily | 1.725 |
Step 6: Click Calculate
The tool will show:
- BMR (Calories)
- TDEE (Calories)

- Weight Loss Calorie Range
Formula Used in WW Calculator
This calculator uses scientifically accepted formulas to estimate energy needs.
1. BMR (Basal Metabolic Rate)
BMR is the number of calories your body needs at rest to maintain basic functions.
Mifflin-St Jeor Formula:
For Men:
BMR = (10 × weight) + (6.25 × height) − (5 × age) + 5
For Women:
BMR = (10 × weight) + (6.25 × height) − (5 × age) − 161
Example Calculation:
Weight = 70 kg
Height = 170 cm
Age = 25
For male:
BMR = (10×70) + (6.25×170) − (5×25) + 5
BMR = 700 + 1062.5 − 125 + 5
BMR = 1642.5 kcal/day
2. TDEE (Total Daily Energy Expenditure)
TDEE represents total calories burned per day including activity.
Formula:
TDEE = BMR × Activity Level
Example:
BMR = 1642.5
Activity = 1.55
TDEE = 1642.5 × 1.55 = 2546 kcal/day
3. WW Points Estimation
This tool uses a simplified estimation:
Formula:
WW Points = TDEE ÷ 70
Example:
TDEE = 2546
WW Points = 2546 ÷ 70 = 36 points/day (approx.)
4. Weight Loss Calorie Deficit
Healthy weight loss requires calorie reduction.
Formula:
- Moderate loss: TDEE − 500 kcal
- Faster loss: TDEE − 750 kcal
Example:
TDEE = 2546
- Moderate deficit = 2046 kcal
- Aggressive deficit = 1796 kcal
Example Calculation Table
| Metric | Value |
|---|---|
| Weight | 70 kg |
| Height | 170 cm |
| Age | 25 |
| Gender | Male |
| Activity Level | Moderately Active |
| BMR | 1643 kcal |
| TDEE | 2546 kcal |
| WW Points | 36 |
| Weight Loss Range | 1796–2046 kcal |
