You’ll have to keep track of your eating and exercising habits on your own. However, this handy calculator will provide you with an accurate baseline to start your fitness or health journey.  
In addition to total daily energy expenditure, our new highly accurate calculator (version 3.5) provides you with the following data.
Here’s some important information for you to be able to use this calculator effectively to achieve your goals.
If you’re searching for the best TDEE Calculator then look no further…
TDEE stands for total daily energy expenditure and this value is found by calculating how many total calories you burn on a daily basis. A calorie or kilocalorie is the amount of heat needed to raise the temperature of one kilogram of water by 1 degree Celsius (1).
So, calories are basically a measure of energy that fuels our physiological functions and activities.
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) (2).
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.
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 = (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

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
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
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.

It’s quite simple actually! Here are step-by-step instructions for using the calculator.
Voila! The calculator will then provide your TDEE estimate results. 
After you punch in the basic info (age, height, weight, 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. (3)
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 (4).
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.
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.
Components of total daily energy expenditure (TDEE)
BMR = basal metabolic rate
NEAT = non-exercise activity thermogenesis
TEF = thermic effect of food
EAT = exercise activity thermogenesis
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. 
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.
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) 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.
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… 
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 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.
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.
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 (11).
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(12).
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.
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.
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…
Tip: Eat fewer calories for losing weight!
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/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 (13).
Protein should also be in moderate amounts as too much can prevent proper ketosis…

TDEE is an acronym for total daily energy expenditure which refers to the total amount of calories burned per day.
If you’re honest with the information you input in the calculator then the estimate should be within 10% of an accurate number. But sometimes it will be necessary to adjust to get the most accurate results.
Our calculator is the best because it was developed by fitness professionals and medically reviewed by doctors. In addition to calculating your total daily energy expenditure, our calculator gives insightful information about your BMI, BMR, Ideal Weight, Calorie Intake, and Daily Macronutrients as a printable PDF report.
This depends on your goal because if you want to lose weight you’ll have to burn more calories than if your goal was to maintain or gain weight.
In general, it’s recommended to burn 500 additional calories over your current daily caloric maintenance to lose one pound per week. Although, there are several more factors that will determine how many calories you need to burn to consistently make progress over the long term.
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.
Yes. It’s the total amount of calories burned in a single day.
You should check your TDEE if your activity levels or weight changes as the number will need to be adjusted.
Calculating your total daily energy expenditure is no longer a stressful process.
But, nowadays we have a calculator for every goal which makes getting in shape and achieving your ideal physique entirely possible in a timely fashion. But, our TDEE Calculator is a fantastic way to establish a starting point from which you can customize to fit your needs.
You’ll learn your caloric requirements for each day and for the week. Plus, you’ll get your BMI, recommended macros, and ideal weight estimate as well.
So, what are you waiting for?… punch in your numbers so there’s no more guessing when it comes to you making progress.
