Calorie Intake Calculator determines your recommended daily calorie intake for weight maintenance, loss, or gain based on your personal characteristics and activity level.
What is Calorie Intake Calculator?
The Calorie Intake Calculator uses scientifically validated formulas to calculate your Total Daily Energy Expenditure (TDEE) and recommend appropriate calorie intake for your goals.
Calorie Intake Formulas
Harris-Benedict Equation
BMR = 88.362 + (13.397 × weight) + (4.799 × height) – (5.677 × age) for men
BMR = 447.593 + (9.247 × weight) + (3.098 × height) – (4.330 × age) for women
Mifflin-St Jeor Equation
BMR = (10 × weight) + (6.25 × height) – (5 × age) + 5 for men
BMR = (10 × weight) + (6.25 × height) – (5 × age) – 161 for women

Activity Level Multipliers
| Activity Level | Daily Multiplier | Description |
|---|---|---|
| Sedentary | 1.2 | Little to no exercise |
| Lightly Active | 1.375 | Light exercise 1-3 days/week |
| Moderately Active | 1.55 | Moderate exercise 3-5 days/week |
| Very Active | 1.725 | Hard exercise 6-7 days/week |
| Extremely Active | 1.9 | Very hard exercise or physical job |
Calorie Adjustments for Goals
- Weight Maintenance: TDEE calories
- Weight Loss: TDEE – 500 calories
- Weight Gain: TDEE + 250-500 calories
