BMR Calculator

Estimate basal metabolic rate from the calculator's body-measurement inputs and inspect the result separately from activity needs.

Working with BMR Calculator

BMR represents an estimate of resting energy requirements before an activity multiplier is applied. Use the basal result to understand the difference between resting needs and the tool's total daily estimate. Review the input units carefully before interpreting either value.

How to use BMR Calculator

  1. Enter age, height, weight, and the available formula inputs.
  2. Choose an activity level and review the assumptions.
  3. Compare the basal and total daily estimates in the results.

BMR Calculator example

Compare the displayed basal estimate with the maintenance estimate for the same inputs. The activity factor accounts for the difference in this model.

What to expect from the result

Estimated BMR is not a measured metabolic rate or a recommended calorie intake. Individual health needs can differ from equation-based estimates.
