# Best TDEE Calculator

## Calculate Total Daily Energy Expenditure (TDEE)

### Our TDEE Calculator (Total Daily Energy Expenditure), calculate your daily calories burn and also display your BMR, BMI, LBM, FBM, Macros & many other useful statistics!

**TDEE **your **Total Daily Energy Expenditure** is an estimation of how many **calories you burn** per day when exercise is taken into account. It is calculated by first figuring out your **Basal Metabolic Rate**, then multiplying that value by an activity multiplier.

Since your **BMR **represents how many calories your body burns when at rest, it is necessary to adjust the numbers upwards to account for the *calories you burn during the day*. This is true even for those with a sedentary lifestyle. Our **TDEE calculator** uses the best formulas and displays your score in a way that’s easy to read and meaningful. **We are also the #1 TDEE Calculator discussed on the Reddit.**

**Out TDEE Calculator have a rich amount of parameters to calculate:**

**BMR**– Basal Metabolic Rate**TDEE**– Total Daily Energy Expenditure**BMI**– Body Mass Index**LBM**– Lean Body Mass**FBM**– Fat Body Mass**WTH**– Waist to Height**MFM**– Maximum Fat Metabolism**MRDC**– Minimum Recommended Daily Calories**Workout Calories****Rest Calories****Weeks to Goal**– Number of weeks to reach goal weight**Obesity Class**

**What is Total Daily Energy Expenditure?**

**Total Daily Energy Expenditure** (TDEE) is an approximate measurement of how many calories you are burning every day. Different than **Basal Metabolic Rate** (BMR), TDEE takes into consideration your daily activity or exercise.

While Basal Metabolic Rate calculates your energy expenditure at rest, **Total Daily Energy Expenditure** adjusts this number and multiply this value by a modifier that depends on the intensity of your daily activities.

**Is it necessary to calculate your Total Daily Energy Expenditure?**

**Calculating your TDEE is essential to adjust your calorie intake** in a real-life scenario. Your **BMR** shows how many calories you burn to keep your body functions, and nothing more. Thus, even if you’re sedentary, you will need to calculate your **TDEE** to find out your daily calorie expenditure.

If you’re physically active, you can input important data such as the intensity of your physical activity, and whether you’re trying to keep your weight, gain lean mass, or lose weight. The results will help you adjust your diet to your current goal and obtain the results you’re looking for in your training protocol.

**How does it work?**

Our Total Daily Energy Expenditure calculator works by obtaining the Basal Metabolic Rate using various formulas you can choose from, such as the **Harris-Benedict** and the **Mifflin-St. Jeor** Formula.

Then, it will automatically adjust the result by taking into consideration your number of workouts per week and your levels of activity.

You will only need to find out your current **weight**, **height**, **body fat percentage**, and **waist circumference**. The rest of the data will be filled according to your current levels of activity and your goals.

You will obtain useful data for your dietary management, such as the calories burnt in rest days vs. workout days, your **lean body mass** (LBM), and **fat body mass** (FBM).

In our **TDEE calculator**, you will also get other measurements you won’t find in other TDEE calculators, such as the **Maximum Fat Metabolism** (MFM) and the **Minimum Recommended Daily Calories** (MRDC).

### Some of The Formulas Used

**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

**Katch-McArdle Equation**

Katch = 370 + (21.6 * LBM)

where LBM is lean body mass

**Revised Harris-Benedict Equation**

Harris-Benedict = (13.397m + 4.799h – 5.677a) + 88.362 (MEN)

Harris-Benedict = (9.247m + 3.098h – 4.330a) + 447.593 (WOMEN)

m is mass in kg, h is height in cm, a is age in years

**Apply your results to achieve your fitness goals**

After calculating your **Total Daily Energy Expenditure** (TDEE), it will be easier to find out the best way to reach your fitness goals.

You can track your Body Mass Index (**BMI**) as well as your lean body mass (**LBM**) and fat body mass (**FBM**) to see how your body composition changes in response to your diet and exercise regime.

You will be able to see an estimate of how many **calories you’re burning in every workout** day and every rest day, and get a useful recommendation by considering the Maximum Fat Metabolism (**MFM**) and Minimum Recommended Daily Calories (**MRDC**) section.

**Maximum Fat Metabolism** (MFM) is a measure of the calorie deficit you need to reach to obtain the maximum fat loss without sacrificing your lean body mass, and it is useful if your goal is losing weight.

The **Minimum Recommended Daily Calories** (MRDC) will show you the minimum daily calories you should aim at if you want to gain lean mass or bulk up.

Our TDEE calculator gives you an estimate of how many weeks it will take for you to get to your desired final weight.

**FAQ**

- What is TDEE?
TDEE stands for Total Daily Energy Expenditure, is the estimated amount of energy in calories you burn per day when exercise is taken into account.

- How do you calculate TDEE?
TDEE is calculated by first finding the BMR (Basal Metabolic Rate) and then multiplying the value with an activity multiplier.

Our TDEE calculator first calculates your BMR using formulas such as the Harris-Benedict and the Mifflin-St. Jeor Formula and then multiplying the values with your ACTIVITY such as

*Sedentary (office job), Light Exercise (1-2 days/week), Moderate Exercise (3-5 days/week), Heavy Exercise (6-7 days/week) or Athlete (2x per day)*.- What is Harris-Benedict Equation
Harris-Benedict = (13.397m + 4.799h – 5.677a) + 88.362 (MEN)

Harris-Benedict = (9.247m + 3.098h – 4.330a) + 447.593 (WOMEN)

m is mass in kg, h is height in cm, a is age in years

- What is Katch-McArdle Equation
Katch = 370 + (21.6 * LBM)

where LBM is lean body mass
