It’s quite simple actually! Here are step-by-step instructions for using the calculator.

1. Choose your unit of measurement in either imperial (lbs and inches) or metric (kg and cm).
2. Select your gender.
3. Enter your age, weight, and height.
4. Pick your activity level:
   • Sedentary (office job)
   • Light Exercise (1-2 days/week)
   • Moderate Exercise (3-5 days/week)
   • Heavy Exercise (6-7 days/week)
   • Athlete (2x per day)
5. Type in your body fat percentage (optional but can give more accurate results).
6. Calculate TDEE

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

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

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

Katch-McArdle Equation

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

Revised Harris-Benedict Equation

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.

TDEE Components

Total daily energy expenditure has several elements. These variables influence your weight differently, helping you maintain it. To determine how daily exercise impacts your body mass, use our online TDEE calculator for weight loss or gain.

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.

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.

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.

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%

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.
