Calculate your Basal Metabolic Rate—the calories your body burns at rest.
Want to understand your metabolism? Use the Free BMR Calculator. It is the Best Basal Metabolic Rate Tool to see exactly how much energy your body needs just to stay alive.
Basal Metabolic Rate is the number of calories your body requires to perform its most basic, life-sustaining functions (breathing, circulation, cell production) if you stayed in bed all day.
BMR is calories burned at rest. Total Daily Energy Expenditure (TDEE) takes your BMR and adds the calories you burn through walking, working, and exercising.
Yes. Muscle tissue burns more calories at rest than fat tissue. Standard BMR calculators estimate based on average body compositions. Very muscular individuals will have a slightly higher actual BMR.
As people age, they generally lose muscle mass and their cellular processes slow down, requiring fewer calories to sustain the body.
BMR is calories burned in a coma-like state. TDEE adds the calories you burn moving around.
Yes, biological gender affects muscle mass averages, which alters the BMR formula.
Yes, metabolism naturally slows down as you get older, which this tool accounts for.
Yes, this free bmr calculator is entirely free.
It gives you the foundational number needed for any serious diet plan.
