What this tool is for
BMR Calculator is built for wellness estimation inside health calculators when you need to estimates resting daily energy needs. It focuses on bmr instead of making you adapt a broad calculator to a narrow task.
When to use it
Use it when weight, height, and age are already known and you want a fast estimate before comparing options, checking a worksheet, or copying the result into another workflow.
Inputs
- Weight is one of the direct inputs used to calculate bmr. Use kg for this field.
- Height describes the size or distance used in the calculation. Use cm for this field.
- Age is one of the direct inputs used to calculate bmr. Use years for this field.
- Sex offset is one of the direct inputs used to calculate bmr. Use 5 male, -161 female for this field.
Formula
BMR = 10w + 6.25h - 5a + sex offset
Example
70 kg, 175 cm, age 30, male offset gives 1,648.75 cal/day.
What the result means
The result labeled "BMR" is the direct output of BMR = 10w + 6.25h - 5a + sex offset. In the worked example, 70 kg, 175 cm, age 30, male offset gives 1,648.75 cal/day.
