Calorie Calculator
Calculate daily caloric needs based on activity and fitness goals. Plan macros effectively.
A calorie calculator estimates how many calories you need daily based on your age, gender, height, weight, and activity level. Understanding your calorie needs is the foundation of any weight management plan.
Examples
Weight Loss Plan
A 30-year-old male, 5'9", 185 lbs, moderately active: BMR ~1,780 cal, TDEE ~2,759 cal. To lose 1 lb/week, target ~2,259 cal/day.
Muscle Gain Plan
A 25-year-old female, 5'5", 135 lbs, very active: BMR ~1,362 cal, TDEE ~2,350 cal. To gain lean muscle, target ~2,600 cal/day with a 250-cal surplus.
Daily Calorie Needs by Activity Level (30-year-old, 5'10", 170 lbs male)
| Activity Level | Description | Estimated Calories/Day |
|---|---|---|
| Sedentary | Desk job, little exercise | 2,100 |
| Lightly Active | Light exercise 1-3 days/week | 2,400 |
| Moderately Active | Moderate exercise 3-5 days/week | 2,650 |
| Very Active | Hard exercise 6-7 days/week | 2,900 |
| Extra Active | Physical job + hard exercise | 3,200 |
Frequently Asked Questions
What is BMR?
Basal Metabolic Rate is the calories your body burns at complete rest just to keep you alive.
What is TDEE?
Total Daily Energy Expenditure is your BMR plus the calories burned through movement and exercise.
How important are macros?
Very. Protein preserves muscle during weight loss, fats support hormones, and carbs fuel activity.
Key Terms
- BMR (Basal Metabolic Rate)
- The number of calories your body burns at complete rest to maintain basic life functions.
- TDEE (Total Daily Energy Expenditure)
- Your total daily calorie burn including BMR, physical activity, and the thermic effect of food.
- Caloric Deficit
- Consuming fewer calories than you burn, which is required for weight loss.
- Macronutrients
- The three main nutrients that provide calories: protein (4 cal/g), carbohydrates (4 cal/g), and fat (9 cal/g).

Quick Tips
- •Track your food intake for a week before making changes to establish your actual baseline.
- •A 500 calorie daily deficit typically results in about 1 pound of weight loss per week.
- •Don't cut calories too aggressively — below 1,200/day (women) or 1,500/day (men) risks nutrient deficiency.
- •Adjust your target every 10-15 pounds lost, as your calorie needs decrease with weight.
