Estimate calories burned at rest.

BMR is the approximate number of calories your body uses at rest before training and daily activity are added in.

How it works

How to use the bmr calculator

BMR Calculator is intended for people who want to learn where maintenance calories start instead of only looking at final calorie targets. Use it to understand the resting calorie side of the equation before adding daily movement and training.

Enter your height, weight, age, and sex, then use the BMR result as the base for broader calorie planning. The calculator returns a BMR estimate.

BMR formulas estimate resting needs from population averages and do not directly measure your body composition or thyroid output. Do not diet from BMR directly. Use it with activity level to estimate maintenance or TDEE first.
