Formula Used

Mifflin–St Jeor estimate:
Men: BMR = 10W + 6.25H − 5A + 5
Women: BMR = 10W + 6.25H − 5A − 161

How the formula is applied

The calculation links Age, Gender and Height ft in — height Feet to basal metabolic rate. BMR describes estimated energy needed for basic body functions at rest. Activity and other daily demands make total expenditure a different quantity.

Calculator Description

Enter Age, Gender and Height ft in — height Feet and the remaining scenario settings to review basal metabolic rate with this tool. BMR describes estimated energy needed for basic body functions at rest.

Estimate resting energy requirements using the equation selected in the form. Distinguish the baseline estimate from calories used during an entire active day.

BMR describes estimated energy needed for basic body functions at rest. Activity and other daily demands make total expenditure a different quantity.

Frequently Asked Questions

What information do I need for the BMR Calculator?

Prepare Age, Gender, Height ft in — height Feet, Height ft in and Weight lbs. Enter age, height and weight in the requested units, then check which equation and sex coefficient the selected method uses.

Is BMR the same as daily calorie expenditure?

BMR describes estimated energy needed for basic body functions at rest. Activity and other daily demands make total expenditure a different quantity. Predictive equations are not metabolic measurements and may fit some individuals poorly. The output is not a minimum diet prescription.

How can I check the bmr calculator with an example?

Use the full settings in the worked-example table. They produce Basal Metabolic Rate: 1510. Compare the method and units as well as the displayed number.

Which assumptions apply to this bmr calculator?

The displayed relationship is Mifflin–St Jeor estimate: Men: BMR = 10W + 6.25H − 5A + 5 Women: BMR = 10W + 6.25H − 5A − 161 Enter age, height and weight in the requested units, then check which equation and sex coefficient the selected method uses.

When should I verify the bmr calculator result elsewhere?

Predictive equations are not metabolic measurements and may fit some individuals poorly. The output is not a minimum diet prescription. For personal care, discuss the measurements and method with a qualified clinician.

How to Use This Calculator

  1. Enter age, height and weight in the requested units, then check which equation and sex coefficient the selected method uses.
  2. Fill in Age, Gender, Height ft in — height Feet and Height ft in; then complete the other fields shown for your selected mode. Use the field units rather than copying an unlabeled value.
  3. For a result check, reproduce the example beginning with Age = 30 and Gender = Female; copy the remaining settings from the detailed guide.
  4. Use the page's Calculate or Convert control, or read the updated result where the tool recalculates automatically. Locate Basal Metabolic Rate and any supporting breakdown.
  5. Interpret the result with this distinction in mind: BMR describes estimated energy needed for basic body functions at rest. Keep the selected inputs alongside the output when comparing scenarios.

Practical example and result check

Worked bmr calculator example. Set Age = 30; Gender = Female; Height ft in — height Feet = 5; Height ft in = 9; Weight lbs = 160. The corresponding output is Basal Metabolic Rate: 1510. BMR describes estimated energy needed for basic body functions at rest.

Before relying on the result

  • Confirm the units, dates, rates and time periods entered.
  • Review which costs, measurements or assumptions are included and excluded.
  • Change one important input at a time to understand the result sensitivity.
