Calorie Calculator (TDEE)

Calculate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) to find calorie targets for maintenance, fat loss, or weight gain.

Summary:A calorie calculator estimates daily energy expenditure using the Mifflin-St Jeor formula and physical activity multipliers, providing daily caloric guidelines tailored for weight maintenance, deficit, or surplus.

How to Use Calorie Calculator (TDEE)

Follow these steps to use the TDEE Calorie Calculator: 1. Enter your age, select your gender, and input weight and height. 2. Select your weekly physical activity level from the dropdown choices. 3. Review your Basal Metabolic Rate (BMR) for baseline calories. 4. Analyze your Total Daily Energy Expenditure (TDEE) for fitness targets. Enter your measurements to calculate the estimate. This tool performs calculations locally in your browser.

Calorie Calculator (TDEE) Formula / How It Works

The calculator estimates BMR using the Mifflin-St Jeor equation and applies physical activity coefficients to determine daily calorie expenditure.

Formula:BMR calculated using Mifflin-St Jeor formula, then multiplied by activity multiplier.
Example Calculation:

For example, let's look at a 30-year-old male, 80 kg, 180 cm tall, with moderate exercise activity level. By entering these values into the tool, you will get a BMR of 1,775 calories and a TDEE of 2,751 calories for daily maintenance instantly.

Frequently Asked Questions

Basal Metabolic Rate. The number of calories your body burns to perform basic life-sustaining functions at complete rest.

Total Daily Energy Expenditure. The total calories you burn per day including all exercise and physical activity.

BMR is your resting calorie burn — the energy your body needs just to stay alive. TDEE builds on BMR by adding your daily activity calories. TDEE = BMR × Activity Multiplier. Use TDEE as your daily calorie budget.

The Mild Loss card shows your TDEE minus 250 kcal/day. This gentle deficit produces approximately 0.25 kg (0.5 lb) of fat loss per week — the most sustainable and least restrictive approach recommended for long-term weight management.

Consuming 300 to 500 calories below your TDEE creates a safe weight-loss calorie deficit. The Mild Loss card (−250) is ideal for beginners. The Cut card (−500) targets 0.5 kg/week loss.

Each card shows a recommended daily calorie intake for a specific goal. Cards with a minimum floor badge indicate the calculated deficit is below the safe minimum (1,200 kcal for women, 1,500 kcal for men). Never follow a calorie target below these floors without medical supervision.

The general minimum recommended daily intake is 1,200 kcal for women and 1,500 kcal for men. Eating below these levels without medical guidance risks nutrient deficiencies and metabolic adaptation. This calculator enforces these floors automatically on all goal cards.

Sedentary (little to no exercise), Light (1–3 days/wk), Moderate (3–5 days/wk), Very Active (6–7 days/wk), Extra Active (physical job and daily workouts).

The speed at which your body converts food intake into usable energy.
