Find your Basal Metabolic Rate (BMR) — the number of calories your body needs just to keep functioning at complete rest.

How This Is Calculated
BMR (Basal Metabolic Rate) is the energy your body burns at complete rest — breathing, circulating blood, and keeping cells alive — before any daily movement or exercise is added.
The Formula
Men: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5. Women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age − 161.
To find your total daily calorie burn including activity, multiply your BMR by an activity factor — use the TDEE calculator to do that automatically.
BMR is your resting baseline—not your daily calorie target.
Your total calorie needs also depend on movement, exercise, digestion, and day-to-day variation. Use the TDEE Calculator for a fuller daily estimate.
