RMR Calculator

Resting Metabolic Rate

Part of the Metabolism Series

Find your RMR and daily calorie estimate

You'll get two results: your Resting Metabolic Rate (RMR) and your Total Energy Expenditure (TEE), each explained.

Used because the standard RMR equation accounts for typical differences in body composition between sexes.

Enter your age to continue.

Uses the same unit system as your weight above.

Enter your height to continue.

This is used to calculate your second result, Total Energy Expenditure, below.

Here are your two numbers at a glance.

RMR

—

at rest

TEE

—

full day

Result 1

Resting Metabolic Rate (RMR)

—

calories / day

What your body burns just staying alive: breathing, circulating blood, running your organs. This is measured at complete rest, before any movement, exercise, or digestion. Think of it as your floor, not a target to hit.

Result 2

Total Energy Expenditure (TEE)

—

calories / day

Your RMR plus the energy you burn moving through your day, including the activity level you selected above. This is a rough estimate of your full daily calorie needs to maintain your current weight.

Both numbers are estimates, not measurements. Use them as a starting point to adjust from based on how your body actually responds over a few weeks, not as fixed targets.
