Enter your height, weight, and age into the calculator to determine your resting energy expenditure (REE).

REE Formula

The following formula is used to calculate a resting energy expenditure (REE):

Males:

REE = RDEE = 66.47 + 13.75 * (W) + 5* (H) – 6.76 * (A)

Females:

REE = RDEE = 65.51 + 9.65 * (W) + 1.84 *(H) – 4.68 (A)

Where REE is resting energy expenditure (kcal)
W is weight (kg)
H is height (cm)
A is age (years)

REE Definition

REE stands for resting energy expenditure. It is a measure of the total energy required for a person’s body to function while resting and doing no activities. This term is sometimes referred to as BMR.

REE is also sometimes referred to as RDEE which stands for resting daily energy expenditure.

Example Problem

How to calculate REE?

First, determine your height.
For this example, the person is measured to be 182.88 cm.
Next, determine your weight.
This person’s weight is measured to be 70kg.
Next, determine your age.
The person in this example is 20 years old.
Finally, calculate the REE.
Using the formula above, the resting energy expenditure is found to be:
REE = 66.47 + 13.75 * (W) + 5* (H) – 6.76 * (A)
REE = 66.47 + 13.75 * (70) + 5* (182.88) – 6.76 * (20)
REE = 1808.17 kcal.
