Method and calculation
Mifflin–St Jeor resting energy is 10w + 6.25h − 5y plus the sex-specific constant.
Inputs and settings
BMR Calculator accepts Height (cm) (minimum 0.000001); Weight (kg) (minimum 0.000001); Age (years) (minimum 18, maximum 100); Formula constant (male, female).
Worked example
BMR Calculator example — Height (cm): 170; Weight (kg): 70; Age (years): 30; Formula constant: "male". Computed output: { "estimatedKcalPerDay": 1617.5 }
Output and limitations
BMR Calculator: Adult estimate only; individual energy needs vary.

BMR Calculator FAQs
BMR Calculator applies the following rule to your input: Mifflin–St Jeor resting energy is 10w + 6.25h − 5y plus the sex-specific constant. The worked example on this page uses the same processor as the result button.
BMR Calculator has these boundaries: Adult estimate only; individual energy needs vary. Start by checking the height (cm) field against the units or format shown.
BMR Calculator provides this sample: { "estimatedKcalPerDay": 1617.5 }. Use the sample button to reproduce it, then replace the inputs with your own values.
