Daily Calorie Needs Calculator
What Is a Daily Calorie Needs Calculator?
A Daily Calorie Needs Calculator estimates the number of calories your body needs per day based on your:
- Gender
- Age
- Height & weight
- Activity level
This value is also called your TDEE (Total Daily Energy Expenditure). Knowing this helps you plan your diet, whether your goal is weight loss, muscle gain, or maintenance.
How It Works
- First, we calculate your BMR (Basal Metabolic Rate) – the calories your body burns at rest.
- Then, we multiply BMR by your activity level factor to estimate your total daily calorie burn.
| Activity Level | Description | Multiplier |
|---|---|---|
| Sedentary | Little or no exercise | 1.2 |
| Lightly active | Light exercise (1–3 days/week) | 1.375 |
| Moderately active | Moderate (3–5 days/week) | 1.55 |
| Very active | Heavy workouts (6–7 days/week) | 1.725 |
| Extra active | Very intense + physical job | 1.9 |
How to Use Your Calorie Needs
| Goal | Action |
|---|---|
| Fat Loss | Eat ~10–25% fewer calories |
| Muscle Gain | Eat ~10–20% more calories |
| Maintenance | Eat equal to daily calorie need |

FAQs
Are daily calorie needs the same for everyone?
No. They vary by gender, age, body size, and lifestyle. Two people of the same weight may have different calorie needs.
Can I lose weight just by reducing calories?
Yes — a calorie deficit causes weight loss. But the best results come from combining this with exercise and good nutrition.
Do I need to count calories every day?
Not always. Use your estimated needs as a guide and track progress weekly. Tools like MyFitnessPal can help.
How often should I recalculate?
Update your calorie needs every time your weight or routine changes significantly (every 4–6 weeks is ideal).
