Enter your weight and the number of hours of inactivity to estimate the number of calories burned. This calculator uses the Basal Metabolic Rate (BMR) to provide an estimate for sedentary individuals.

Inactive Calories Burned Formula

The formula used to estimate the calories burned during inactivity is based on the Basal Metabolic Rate (BMR) calculated using the Mifflin-St Jeor Equation:

Calories Burned = (BMR / 24) * Hours of Inactivity

Variables:

  • BMR is the Basal Metabolic Rate, which is the number of calories required to keep your body functioning at rest.
  • Hours of Inactivity is the total number of hours spent without engaging in any physical activity.

To estimate the calories burned during inactivity, calculate the BMR using the Mifflin-St Jeor Equation and then multiply it by the hours of inactivity divided by 24 (the number of hours in a day).

What is Inactive Calories Burned?

Inactive calories burned refer to the energy expended by the body during periods of inactivity, such as sitting or lying down. The body burns calories to maintain vital functions like breathing, circulating blood, and regulating body temperature. This calculator provides an estimate of the calories burned based on the individual’s Basal Metabolic Rate (BMR) during a specified period of inactivity.

How to Calculate Inactive Calories Burned?

The following steps outline how to estimate the Inactive Calories Burned.


  1. First, determine your weight in pounds.
  2. Next, determine the number of hours of inactivity.
  3. Use the BMR based on the Mifflin-St Jeor Equation to calculate the calories burned per day.
  4. Finally, calculate the Inactive Calories Burned by multiplying the BMR by the hours of inactivity divided by 24.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Weight = 150 pounds

Hours of Inactivity = 8 hours
