What is a TDEE Calculator?
Understanding Total Daily Energy Expenditure (TDEE)
Your Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns daily, accounting for your Basal Metabolic Rate (BMR) and activity level. BMR is the energy your body uses at rest for essential functions like breathing, circulation, and cell production. TDEE builds on BMR by factoring in your physical activity, from sedentary lifestyles to intense workouts.
The TDEE Calculator on tooll.live uses the Mifflin-St Jeor Equation, one of the most accurate methods for estimating BMR, and multiplies it by an activity factor to calculate your TDEE. This offline tool requires no internet connection for calculations, ensuring fast, reliable results based on your inputs: age, gender, weight, height, and activity level.

How to Use the TDEE Calculator on tooll.live
Step-by-Step Guide to Calculating Your TDEE
Using the TDEE Calculator on tooll.live is straightforward. Follow these steps to get accurate results tailored to your fitness goals:
- Access the Calculator: Visit tooll.live and navigate to the TDEE Calculator under the health and fitness category.
- Enter Your Age: Input your age (between 10 and 120 years) to account for age-related metabolic changes.
- Select Your Gender: Choose male or female, as the Mifflin-St Jeor Equation adjusts BMR calculations based on gender-specific constants.
- Input Your Weight: Provide your weight in kilograms (20–300 kg range) for precise BMR estimation.
- Input Your Height: Enter your height in centimeters (80–250 cm range) to factor in body size.
- Choose Activity Level: Select from five activity levels:
- Sedentary (1.2): Little or 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.
- Extra Active (1.9): Very hard exercise and a physical job.
- Calculate: Click the “Calculate” button to instantly see your BMR, TDEE, and approximate daily energy cost.
- Review Results: Your results will display in a clear, organized format. Use the “Print” or “Share” buttons to save or share your results via email.
- Reset if Needed: Use the “Reset” button to clear inputs and start over.
Example Input for Clarity
For instance, a 30-year-old male, weighing 70 kg, standing 175 cm tall, and moderately active (exercising 3–5 days/week) would input:
- Age: 30
- Gender: Male
- Weight: 70 kg
- Height: 175 cm
- Activity Level: Moderately Active (1.55)
The calculator uses the Mifflin-St Jeor Equation:
- Male BMR = (10 × weight) + (6.25 × height) − (5 × age) + 5
- BMR = (10 × 70) + (6.25 × 175) − (5 × 30) + 5 = 700 + 1093.75 − 150 + 5 = 1658.75 kcal/day
- TDEE = BMR × Activity Factor = 1658.75 × 1.55 = 2571 kcal/day
This result helps users plan for weight loss, muscle gain, or maintenance by adjusting calorie intake accordingly.
Why Use the TDEE Calculator?
Benefits for Weight Loss
For those targeting TDEE calculator for weight loss, understanding your TDEE is crucial. To lose weight, you need to consume fewer calories than your TDEE, creating a caloric deficit. For example:
- A TDEE of 2571 kcal/day means consuming 2071–2271 kcal/day (a 300–500 kcal deficit) can lead to safe weight loss of 0.5–1 pound per week.
- The calculator’s activity factors ensure your caloric needs reflect your lifestyle, making it easier to plan meals or track macros.
Benefits for Muscle Gain
For TDEE calculator for muscle gain, the tool helps you determine the surplus needed to support muscle growth. Consuming 250–500 kcal above your TDEE, paired with strength training, promotes muscle hypertrophy. The precise activity level selection ensures your caloric surplus aligns with your workout intensity.
Benefits for Maintenance
If your goal is to maintain weight, the TDEE Calculator provides your exact caloric needs. This is especially useful for individuals with active lifestyles or those transitioning from weight loss to maintenance.

FAQs
What is the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the calories your body burns at rest for basic functions. TDEE (Total Daily Energy Expenditure) includes BMR plus calories burned through physical activity. The TDEE Calculator on tooll.live provides both metrics for comprehensive planning.
How accurate is the TDEE Calculator?
The calculator uses the Mifflin-St Jeor Equation, widely regarded as the most accurate BMR estimation method. However, TDEE is an estimate, as actual energy expenditure varies based on individual factors like muscle mass or metabolism. Always consult a professional for personalized advice.
Can I use the TDEE Calculator for cutting calories?
Yes! The TDEE calculator for cutting calories helps you determine your maintenance calories and create a safe deficit (e.g., 300–500 kcal below TDEE) for weight loss. The activity factor ensures your caloric needs align with your lifestyle.
Does the TDEE Calculator provide macro breakdowns?
While the current version focuses on BMR, TDEE, and energy cost, you can use the TDEE result to calculate macros manually (e.g., 40% carbs, 30% protein, 30% fat). Future updates on tooll.live may include macro-specific features for a TDEE calculator with macros.
Is the TDEE Calculator free to use?
Yes, the TDEE Calculator on tooll.live is completely free, with no subscriptions or hidden fees. It’s part of a wide range of tools designed to empower users.
How do activity factors affect TDEE?
Activity factors adjust your BMR based on your daily physical activity. For example, a sedentary lifestyle (1.2) results in a lower TDEE than a very active one (1.725). The TDEE calculator with activity factors ensures your results reflect your unique routine.
Can I embed the TDEE Calculator on my website?
Absolutely! The calculator’s code is available on tooll.live for embedding. It’s perfect for fitness websites or blogs targeting how to embed a TDEE calculator on website searches, enhancing user engagement with minimal setup.
Is the TDEE Calculator suitable for all ages?
Yes, it’s designed for ages 10–120, accommodating young adults, adults, and seniors. However, results are estimates, and users with specific health conditions should consult professionals.
How often should I recalculate my TDEE?
Recalculate your TDEE every 4–6 weeks or after significant changes in weight, activity level, or fitness goals. This ensures your caloric intake aligns with your current needs.
Why is the TDEE Calculator offline?
The offline functionality ensures fast, private calculations without relying on internet connectivity. Your data stays on your device, making it secure and accessible anytime.
