This calculator is based on the industry-standard Revised Harris-Benedict Equation, validated for accuracy in total daily energy expenditure estimations.
The Best TDEE Calculator is a powerful tool designed to accurately estimate the number of calories your body burns per day. This calculation is essential for planning a diet whether your goal is weight loss, maintenance, or gain.

The calculation relies on two key steps: first, determining your Basal Metabolic Rate (BMR), and second, applying a multiplier based on your physical activity.
Step 1: Basal Metabolic Rate (Revised Harris-Benedict Equation)
Male BMR = 88.362 + (13.397 x Weight in kg) + (4.799 x Height in cm) - (5.677 x Age in years)
Female BMR = 447.593 + (9.247 x Weight in kg) + (3.098 x Height in cm) - (4.330 x Age in years)
Step 2: Total Daily Energy Expenditure (TDEE)
TDEE = BMR x Activity Multiplier
Variables
Understanding the inputs ensures the most accurate TDEE estimate:
- Gender & Age: Essential components of the BMR equation, accounting for metabolic differences.
- Height & Weight: These metrics contribute significantly to the total body mass needing fuel (calories).
- Activity Level: The multiplier that scales BMR to TDEE, based on how much you move daily.
What is best TDEE Calculator?
TDEE stands for Total Daily Energy Expenditure. It is the total number of calories your body uses in a 24-hour period to maintain all bodily functions, including breathing, digestion, movement, and exercise. It represents the true caloric “break-even” point for your body.
The TDEE calculator uses an established formula, like the Revised Harris-Benedict Equation, to first estimate your Basal Metabolic Rate (BMR) – the calories burned purely at rest. It then multiplies this BMR by an activity factor to account for your lifestyle and exercise habits, giving you the most comprehensive estimation of your daily caloric needs.
Knowing your TDEE is fundamental to any physique-based goal. To lose weight, you must consistently consume fewer calories than your TDEE (a deficit). To gain weight, you must consume more (a surplus). For maintenance, you aim to match your TDEE precisely.
How to Calculate best TDEE Calculator (Example)
Here is a step-by-step example for a 30-year-old male, 175 cm tall, weighing 75 kg, with a Moderately Active lifestyle (AF = 1.55):
- Determine BMR (Male): $BMR = 88.362 + (13.397 \times 75) + (4.799 \times 175) – (5.677 \times 30)$ $BMR = 88.362 + 1004.775 + 839.825 – 170.31$ $BMR \approx 1762.65$ Calories
- Apply Activity Factor: $TDEE = BMR \times Activity\ Factor$ $TDEE = 1762.65 \times 1.55$
- Final TDEE Calculation: $TDEE \approx 2732$ Calories per day.

Frequently Asked Questions (FAQ)
BMR (Basal Metabolic Rate) is the minimum number of calories required to keep your body functioning at rest. TDEE (Total Daily Energy Expenditure) is the BMR plus the calories burned through all daily activities and exercise.
How accurate is this TDEE calculator?While formulas like the Revised Harris-Benedict provide a very accurate estimate for the general population, they are still estimates. Factors like body composition (muscle vs. fat) or hormonal health can cause minor deviations from the calculated result.
Do I need to adjust my TDEE if I start exercising more?Yes. If your exercise habits change, you must select the corresponding Activity Level to get an updated, accurate TDEE. For example, moving from ‘Lightly Active’ to ‘Very Active’ will significantly increase your TDEE.
Should I eat exactly my TDEE?If your goal is weight maintenance, yes. If you aim for weight loss, you should eat less than your TDEE (a caloric deficit). If you aim for weight gain, you should eat more (a caloric surplus).
