BMR Calculator, or Basal Metabolic Rate Calculation

Basal Metabolic Rate Calculator Sign

This BMR and TDEE calculator will help you to calculate the total calories you would expend if you spent all day resting and doing nothing, which is also referred to as your "metabolism."

Plus, the calculator will use your calculated BMR to estimate your Total Daily Energy Expenditure (TDEE) for each of 5 different activity levels.

Finally, the calculator will also display a chart and graph showing your estimated BMR at each age over the next 20 years.

As you get older, your metabolism tends to slow down, making it increasingly difficult to maintain and lose weight.

Calculating your Basal Metabolic Rate at each age will help keep you abreast of where your activity level needs to be in order to lose or maintain weight (see Weight Calorie Tool for calculating caloric adjustments needed to achieve weight goals).

Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

Height:

Enter your height (without shoes on) in your selected unit of measurement. Inches for standard and centimeters for metric. Use the decimal equivalents for fractions (for 1/4 enter .25, for 1/2 enter .5, for 3/4 enter .75).

If you need to convert feet and inches to inches, expand the description to reveal a mini feet-to-inches conversion calculator.

Your Basal Metabolic Rate:

Based on your entries, this is your resting metabolic rate (metabolism), which is essentially the number of calories you would burn if you laid in bed all day.

Total Daily Energy Expenditure (TDEE):

Once you know your Basal Metabolic Rate, you can use that figure to estimate the total number of calories you burn per day. The following fields indicate your estimated total daily energy expenditure (TDEE) based on each of 5 activity levels.

None:None:No activity level:No activity level:

No activity level:

Little to zero exercise. This is equal to your BMR x 1.2.

Low:Low:Low activity level:Low activity level:

Low activity level:

Low exercise or sports 1 to 3 days per week. This is equal to your BMR x 1.375.

Medium:Medium:Medium activity level:Medium activity level:

Medium activity level:

Medium exercise or sports 3 to 5 days per week. This is equal to your BMR x 1.55.

High:High:High activity level:High activity level:

High activity level:

Intense exercise/sports 6 to 7 days per week. This is equal to your BMR x 1.725.

Intense:Intense:Intense activity level:Intense activity level:

Intense activity level:

Intense twice daily exercise, intense physical job. This is equal to your BMR x 1.9.

If you would like to save the current entries to the secure online database, tap or click on the Data tab, select "New Data Record", give the data record a name, then tap or click the Save button. To save changes to previously saved entries, simply tap the Save button. Please select and "Clear" any data records you no longer need.

Help and Tools

Adjust Calculator Width:

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".

Show/Hide Popup Keypads:

Select Show or Hide to show or hide the popup keypad icons located next to numeric entry fields. These are generally only needed for mobile devices that don't have decimal points in their numeric keypads. So if you are on a desktop, you may find the calculator to be more user-friendly and less cluttered without them.

Stick/Unstick Tools:

Select Stick or Unstick to stick or unstick the help and tools panel. Selecting "Stick" will keep the panel in view while scrolling the calculator vertically. If you find that annoying, select "Unstick" to keep the panel in a stationary position.

If the tools panel becomes "Unstuck" on its own, try clicking "Unstick" and then "Stick" to re-stick the panel.
