  6. Calculate TDEE

Voila! The calculator will then provide your TDEE estimate results.

Watch how to use our calculator: 

How To Read My TDEE?

After you punch in the basic info (age, height, weight, daily activity level, and body fat %) required; you’ll see a few different approximate values. Now, these results are pretty simple to understand and we’ve provided a brief definition of each.

Maintenance calories calculated – The calculator provides the same results as a maintenance calorie calculator and this value is the number of calories you need to consume to maintain your current body weight.

Calories per week – This is the total number of calories you’ll eat in one week based on your fitness goals.

Ideal weight – This value is simply a recommendation for a healthy weight but the more muscle you have, the less you need to really worry about this part.

Body mass index (BMI) score – BMI score is based on your height and weight. Now, the ranges aren’t always 100% accurate, so if you happen to be within these numbers, consider your body fat level to gauge whether or not you have a healthy BMI [1].

  • 18.5 or less (Underweight)
  • 18.5 – 24.9 (Normal weight)
  • 25 – 29.9 (Overweight)
  • 30 – 40 (Obese)
  • 40+ (Extremely obese)

Tip: Also try our BMI and  reverse BMI calculator.

Macronutrients – Macronutrients are needed in large amounts so this is a big focus for meeting your recommended daily caloric requirements [2].

Now, macros aren’t typically included in a standard TDEE calculator since most tend to act only as a calories burned tool.

But, our TDEE formula includes both training day and rest day macros. So, you can know exactly how much protein, carbs, and fats to consume every day to reach your goals. And these numbers vary based on all of the required necessary information including weight, and activity level.

  • Protein is the building block of muscle tissue and the TDEE formula factors it into your diet based on your needs [3].
  • But, carbs are an essential energy source that can break down fast enough to support your high-intensity exercise. And carbs are proven to support anabolism which is necessary for muscle growth [4].
  • Fats are also very important for brain function, testosterone production, and metabolism regulation. So, all macros are taken into account for optimal health based on all factors that you enter in the calculator [5].

What is TDEE?

TDEE stands for total daily energy expenditure and this value is found by calculating how many total calories you burn on a daily basis from normal bodily functions and physical activity. A calorie or kilocalorie is the amount of heat needed to raise the temperature of one kilogram of water by 1 degree Celsius [6].

It’s like your body’s daily energy budget. Understanding your TDEE is crucial for achieving your fitness goals. Your TDEE can change as you gain muscle, lose weight, or become more active. It’s a guide for your nutrition that should be regularly revisited. Depending on your fitness goals, you may aim to eat less than your TDEE to lose weight, more than your TDEE to gain muscle, or adjust your macronutrient ratios to maintain your weight while changing your body composition.

How TDEE is Calculated

There are several equations for calculating TDEE but the Mifflin-St Jeor equation is known to be the most accurate (So, we’ll focus on this formula). 

According to one study, this equation is accurate to within 10% of RMR (Resting metabolic rate) [7].

This was determined by comparing Mifflin-St Jeor, Katch-McArdle to the Harris-Benedict, Owen, and World Health Organization/Food and Agriculture Organization/United Nations University [WHO/FAO/UNU] formulas.

TDEE Calculation Methods

First, we use the Mifflin-St Jeor formula to calculate your BMR (Basal Metabolic Rate), and then we calculate the results base on your physical activity level.

Mifflin-St Jeor Equation

Mifflin = (10.m + 6.25h – 5.0a) + s
m is mass in kg, h is height in cm, a is age in years, s is +5 for males and -151 for females

The formula for the Mifflin-St Jeor is as follows for each gender…

Men: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) + 5 
Women: 10 x weight (kg) + 6.25 x height (cm) – 5 x age (y) – 161

Katch-McArdle Equation

If you know your body fat percentage and fill out the field, the calculator will instead use the Katch-McArdle Formula.

Katch = 370 + (21.6 * LBM)
LBM = lean body mass

Revised Harris-Benedict Equation

MEN: (13.397m + 4.799h – 5.677a) + 88.362 
WOMEN: Harris-Benedict = (9.247m + 3.098h – 4.330a) + 447.593
m is mass in kg, h is height in cm, a is age in years

The new revised Harris-Benedict equation has been in use since 1984, and we calculate this as well for those who want it.

Thankfully, you don’t have to figure these numbers by hand, as you only need to enter a few basic fields to get an accurate result from this formula.

Although, you can simply plug the variables and see how it works.

BMR

The basal metabolic rate (BMR) is the amount of energy expended at rest. In other words BMR is the number of calories your organs need to function even if you do nothing all day, like stay in bed. Everyone needs a certain amount of calories and the BMR is this minimum number. 

Non-Exercise Activity Thermogenesis (NEAT)

NEAT includes calories burned during non-structured daily activities. Movement from room to room, taking the stairs to the office, etc. NEAT is person-specific. TDEE is based on NEAT and daily physical activity.

Thermic Effect of Food (TEF)

Thermal Effect of Food, or TEF is is the body’s energy used to digest food. TEF accounts for approximately 10% of daily energy expenditure. It involves breaking down proteins, carbs, and fats used by the body’s processes. Hormone synthesis, neurotransmitter production, tissue growth, etc.

Exercise Activity Thermogenesis (EAT)

Exercise activity thermogenesis (EAT) is the number of calories your burns when exercising, EAT typically accounts for 5% to 10% of your metabolism.

Check out the table below to determine how much each component of TDEE contributes to its overall calculations.

Component of TDEE Percent of TDEE 1600 kcal TDEE 2600 kcal TDEE 3600 kcal TDEE
TEF 8–15 128–240 208–390 288–540
EAT 15–30 240–480 390–780 540–1080
NEAT 15–50 240–800 390–1300 540–1800
BMR 60–70 960–1120 1560–1820 2160–2520

How Many Calories do I Burn Per Day?

To figure how many calories you burn in a day, you can use the Mifflin-St Jeor equation which we use for our TDEE calculator, as it already factors in your BMR or basal metabolic rate.

BMR is the amount of energy your body burns or needs to function at rest (breathing, body temperature regulation, etc.) [8].

So, your BMR plus activity level will determine how many calories you burn in a day. But, it’s important to know that the more muscle you have, the more calories you’ll burn. So these numbers can vary a bit.

According to research, the body burns about 50 additional calories per each pound of muscle that you have [9].

So, you might want to use our body fat calculator to get a better idea of just how much lean body muscle mass you’re carrying because you might be a fat-burning machine and not even know it… 

How Many Calories Should I Eat in a Day?

This is entirely independent of each individual’s current weight, BMR, TDEE, and goals (gain, maintain or lose weight). But, adjusting your calories by roughly 500 above or below your maintenance calories will help you achieve the desired outcome in the safest manner possible [10].

Keep in mind though, that the 500-calorie rule does not apply in all situations and may be most effective initially. In fact, it’s been called a 500-calorie deficit myth as of recent so we don’t recommend that everyone adjust their calories 500 calories below or above maintenance especially the farther along you are in your weight journey.

Our tdde calorie calculator can also provide you with the ideal caloric intake recommendation but once you know your maintenance calories, it’s smooth sailing if you’re aware of the following guidelines.

  • If you want to lose a pound a week, you’ll have to eat 500 calories less than your recommended maintenance calories each day.
  • If you want to gain one pound a week, you’ll have to eat 500 calories over your maintenance calories each day.
  • For maintenance, keep your caloric intake and activity levels consistent.

Use our calories to eat per day calculator, this calculator will give you the science backed estimate of your recommended daily calorie intake for weight loss or gain.

Study: In a study by the Department of Human Biology, Nutrition and Toxicology Research Institute Maastricht, Maastricht University, examining the effects of overfeeding and cold exposure on Total Daily Energy Expenditure (TDEE), results showed that both factors significantly increased TDEE. The changes in energy expenditure during both conditions were strongly correlated, as were fasting norepinephrine plasma concentrations. [11]

How Many Calories Should I Burn per Day?

If you want to lose one pound per week, then you’ll have to burn 500 additional calories each day below your maintenance calories.

But for a two-pound weight loss, you’ll need to burn 1,000 calories per day.

One pound of body weight equals 3,500 calories which are the number of additional calories you’d need to burn in one week to lose a pound [12].

But, to create a caloric deficit you can either eat less, exercise more, or do a little of both. So, if you’re the type who enjoys your food (Like the rest of us), then you can hit the cardio machine or go for a run to make up the deficit.

Barry M. Popkin, Ph.D., and the director of the Interdisciplinary Obesity Program at the University of North Carolina, Chapel Hill explained… “Essentially, we know of no way to burn more calories or up our metabolism than to move more” [13].

So, being active is always the best method for burning more calories.

Or, you can just cut back on your portions but always make sure to read the labels to keep track of your calories consumed throughout the day.

TDEE Calculator for Weight Loss

So, how do you use our TDEE Calculator to achieve your weight loss goals?

Our TDEE Calculator can be use easily as a weight loss calculator or a daily calorie intake calculator to achieve your fitness goals. To lose weight you eat less and to gain weight you eat more than your TDEE.

We also recommend that you use Macro Counting to hit your daily calorie intake and create a calorie deficit in order to lose weight in a healthy and sustainable way.

How to Calculate Macros

Our Calculator takes care of your macros, but we also have a macro calculator specifically for this purpose.

TDEE Macros Ratios

However, to calculate your macros without a calculator you’d need to know your TDEE first. And then you can follow the widely accepted and recommended ratio for macro percentages after you’ve added or subtracted 500 or so calories from your maintenance number.

Here are the macro percentages…

Bulking / Muscle Gain

  • Protein: 25-35%
  • Carbs: 40-60%
  • Fat: 15-25%

Cutting / Fat loss / Weight Loss

  • Protein: 40-50%
  • Carbs: 10-30%
  • Fat: 30-40%

Tip: Eat fewer calories for losing weight!

Maintenance Calories

  • Protein: 25-35%
  • Carbs: 30-50%
  • Fat: 25-35%

Our calculator gives you exact numbers rather than percentages and it also provides recomposition (Gain back lost muscle quickly) macro percentages as well.

However, everyone is different and can manipulate these figures in small increments to fit their needs.

Now, if you’re doing the ketogenic diet plan/lifestyle you will benefit from a different ratio of macro percentages since the goal is reaching ketosis; which utilizes fat as the main energy source rather than carbs [14].

Protein should also be in moderate amounts as too much can prevent proper ketosis…

Keto Macros

  • Fat: 70-80%
  • Protein: 20-25%
  • Carbs: 5-10%

Also try the keto macro calculator!

Key Factors Affect Your TDEE

  • Macronutrients (carbohydrates, proteins, and fats) are essential for maintaining energy levels and overall health and affect the TDEE as it can change the number of calories your body burns at rest and during physical activity.
  • Physical activity level plays a significant role in determining TDEE as it increases the number of calories your body burns.
  • Chronic dieting and weight cycling can lead to a decrease in TDEE.
  • Genetics plays a significant role in determining TDEE.
  • Sleep and stress management are essential for maintaining a healthy TDEE.
  • Hormone imbalances, such as an under-active thyroid or high levels of cortisol, can affect TDEE.
  • Age, as individuals age, their TDEE decreases.
  • Hydration plays a vital role in TDEE.
  • Chronic illness can affect TDEE
  • NEAT (non-exercise activity thermogenesis) can account for a significant portion of a person’s TDEE and can vary greatly between individuals. Increasing NEAT through simple activities can help to boost TDEE and aid weight loss.

Frequently Asked Questions

What Does TDEE Mean?

TDEE is an acronym for total daily energy expenditure which refers to the total amount of calories burned per day.

How to Calculate TDEE?

The easiest way to determine your BMR (Basal Metabolic Rate) is by using the Mifflin-St Jeor formula. Now to calculate your TDEE, simply multiply your BMR by your activity level. TDEE = BMR x 1.9

How accurate is TDEE for weight loss?

How accurate is TDEE (Total Daily Energy Expenditure) for weight loss? TDEE calculations help estimate daily caloric needs and are vital for creating personalized weight loss plans. Although not 100% accurate, TDEE estimations have an accuracy range of ±10% when users report their activity levels correctly. To optimize TDEE accuracy, use our reliable calculator, provide accurate data, and update your information regularly to ensure tailored weight loss strategies align with your specific goals.

What is the most accurate TDEE calculator?

What is the most accurate TDEE (Total Daily Energy Expenditure) calculator? For individuals without knowledge of their body fat percentage, the Mifflin-St Jeor equation is considered the most precise option, providing reliable estimates based on age, gender, weight, and height. However, for those with access to their body fat percentage data, the Katch-McArdle equation offers superior accuracy, as it factors in lean body mass to provide a more personalized and precise TDEE calculation. Both equations enable individuals to understand their daily caloric needs, essential for achieving fitness and weight management goals.

How many calories should I burn every day?

The number of calories you need to burn depends on what you’re trying to achieve. If weight loss is your goal, you’ll need to burn more calories than if you’re maintaining or gaining weight. To lose one pound per week, it’s typically recommended to burn 500 additional calories beyond your current daily maintenance level. Keep in mind, there are other factors that can impact how many calories you need to consistently see progress in the long run.

How many calories over TDEE should I eat to bulk up?

Start with 250-330 calories per day for a slow bulk to minimize fat gain. When you plateau, increase your calories by an additional 250 calories every day and repeat the process.

Does TDEE include exercise?

Yes. It’s the total amount of calories burned in a single day.

How often do I need to calculate my TDEE?

To ensure the accuracy of your TDEE calculation, it’s recommended to check it regularly if your activity levels or weight fluctuate. You may need to adjust the number to account for these changes.

Final Thoughts

In conclusion, the TDEE (Total Daily Energy Expenditure) calculator is an invaluable tool for anyone looking to better understand their caloric needs for optimal health and fitness. By taking into account your age, gender, height, weight, activity level, and goals, this calculator offers a personalized estimate of the number of calories you need to consume daily to maintain, lose, or gain weight Plus, you’ll get your BMI, recommended macros, and ideal weight estimate as well.

Keep in mind that the TDEE is merely a starting point on your path to improved health and fitness. Your TDEE may fluctuate as you make changes to your diet and exercise routines, so don’t forget to re-assess your caloric needs from time to time.

    In theory, if I consume any food within my TDEE limit, can I still lose fat?

      Per our dietitian expert: I would recommend focusing on a balanced and nutritious diet to support overall health and well-being, rather than solely relying on calorie intake to lose weight. While it is theoretically possible to lose weight while consuming any type of food within your TDEE limit, a diet that prioritizes nutrient-dense foods will generally lead to better long-term outcomes.

    Thank you, this is the best TDEE calc I have used… I have a question can you explain a bit more about macro ratio for the cutting / weight loss, would it be okay to increase carb intake by 5%?

      Glad you found the TDEE calculator helpful! To lose weight, have moderate to high protein, moderate fat, and lower carbs but increasing carb intake by 5% likely won’t hurt weight loss as long as you’re in a caloric deficit. Experiment to find what works best for you 🙂

    Hey can you explain me the difference between your BMR and your TDEE?

      BMR is the amount of energy your body needs to function at rest, while TDEE is the total number of calories your body burns in a day, including physical activity and exercise.

    The most accurate way to estimate your TDEE; I exercise 6 days a week for at least 35 min per day, which gave me a TDEE of 2300.. Good job 👍👍

    Hey… this calculator uses the Mifflin-St Jeor Formula for calculating Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE). Can you explain why this formula is considered the most accurate compared to other formulas like Harris-Benedict and Katch-McArdle?

      Hello Jackie, it’s great to hear from you. Our calculator employs the Mifflin-St Jeor Equation, the Katch-McArdle Equation, and the Revised Harris-Benedict Equation to calculate BMR and TDEE. The Mifflin-St Jeor Formula is often considered the most accurate because of its thorough approach, taking into account weight, height, age, and gender. This formula’s accuracy has been validated in recent studies and is found to be more precise across diverse populations. While the Katch-McArdle and Harris-Benedict formulas are also used, the Mifflin-St Jeor stands out for its consistency and reliability in estimating metabolic rates.

    I was also wondering the same + given that the TDEE calculator provides estimates within a 10% accuracy range of the Resting Metabolic Rate (RMR), what are the implications for individuals using this tool for precise dietary and exercise planning, and how can they compensate for this margin of error in practical application?

      Hey Rose, the calculator, using the Mifflin-St Jeor Equation, provides an estimate with a 10% accuracy range of the Resting Metabolic Rate (RMR), it’s important for individuals to consider this margin when using it for precise dietary and exercise planning. This tool offers a solid starting point, but individuals should monitor their body’s response to dietary and exercise changes and adjust accordingly. Tracking progress over time and making incremental adjustments based on real-world outcomes is key to compensating for this margin of error and achieving more personalized and effective results.

    This is very nice, I have a question.. how does your TDEE calculator adjust the estimated daily caloric needs based on different levels of physical activity, ranging from sedentary to athlete-level exercise, and what impact does this have on the accuracy of the TDEE estimation?

    Forum reply »

    • Tom Miller, CSCS Tom Miller, CSCS says:

      Hello Shyam Kumar, great question. our calculator adjusts the estimated daily caloric needs by integrating an individual’s self-reported activity level, which ranges from sedentary to athlete-level exercise. This inclusion is crucial for accurately determining the Total Daily Energy Expenditure (TDEE). The adjustment reflects the varying caloric requirements based on the extent of physical activity, ensuring that the calculated TDEE aligns more closely with an individual’s actual energy expenditure. This approach enhances the accuracy of the TDEE estimation, making it a more tailored tool for individuals with diverse lifestyle and exercise habits.

    Hi Tom,
    What happened to the old TDEE calculator that I found via Reddit? Did you guys discontinue it? I really liked the everyday tracker feature in it. Do you have any plans to bring it back anytime soon?

    Thank you,

      Hello Natalie,

      Thanks for your appreciation and your great question! Yes, when cutting, increasing protein intake while reducing carbohydrates can be beneficial. Protein is crucial for muscle preservation and recovery, especially during a calorie deficit. It’s also more satiating, which can help manage hunger. However, remember that carbs are important too, as they fuel your workouts and overall energy levels. It’s all about finding the right balance that works for your body and fitness goals. Keep tracking your intake and adjust as needed for the best results. Keep up the good work!

      Tom

    Unsure what I should pick in terms of Activity level…I feel I am somewhere between moderate and heavy. I will post my normal weekly activity:

    Strength Training Workouts are short but intense, 20-25 minutes with typically 40-55 seconds of work followed by 5-20 second rest periods depending on the week and what I am training for that week. I do that 4 times a week training legs, chest, back, arms/shoulders on a 2 on, 1 off, 2 on, 2 off weekly cycle. These workouts are followed by intense slamball finishing work with a 20, 30 or 40 lb slamball(overhead slams) doing AMRAP for 5 minutes. Heart rate usually is in the 145-160 range after that.

    Typically walk 14-15K steps a day at a pace of between 2.5-3.0 mph while working on my walking pad and then do 40 minutes of elliptical work 5-6 days a week at a pace of about 4 mph, which pushes my heart rate to around 135-140 bpm once I am done.

    What would you consider that type of activity level? Moderate or Heavy?

    I am 49 years old, 5’8″ tall and weigh 179 lbs. I have a thick, fairly muscular build(due to years of heavy weight training) and estimated 15% BF based on calipers and tape measurement calculations. Waist is around 33.8 inches. My upper 4 abs are very visible, lower abs are still covered by some fat which seems to be dwindling every day. Goal is to hit 165 lbs by early May, what would be the best path to get there in terms of calories/day. Also carb cycle weekly: HC(2300 cals), MC(2200 cals), LC (2064 cals), LC(2064 cals), HC(2300 cals), LC(2064 cals), LC(2064) with high carb days being Legs and Arms/Shoulder, Medium Carb being chest and lower carb being back day. All 3 non lifting days are low carb days.

    Do those calorie counts seem about right or are they too low? There are days when I am pretty hungry, but most days I am able to stay on track since I build out meal plans for the week ahead of time and have thing measured to the gram.

      Hi Matt,

      Based on your detailed description of your weekly activity, I would categorize your activity level as heavy. Your strength training sessions, slamball work, daily walking, and elliptical workouts are all significant contributors to your overall energy expenditure. For your goal of reaching 165 lbs by early May, it’s crucial to maintain a caloric deficit while ensuring you’re getting enough nutrients to support your workouts and muscle recovery.

      As for your current calorie counts, they seem to be well-structured for carb cycling, but if you’re experiencing hunger on certain days, it might be worth reassessing your caloric intake or macronutrient distribution on those days. Since everyone’s metabolism and body response are unique, I recommend monitoring your progress and adjusting your calorie intake as needed to ensure you’re on track to reach your goal while maintaining your energy levels and muscle mass.

      Best of luck on your fitness journey!
      Tom
