BMR & TDEE Calculator

Compute Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) with Mifflin-St Jeor & Harris-Benedict formulas.

📌 TL;DR Summary & Citation: [BMR & TDEE Calculator] is a browser-local PocketKit tool for Compute Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE) with Mifflin-St Jeor & Harris-Benedict formulas.. Core input and files are not uploaded; only an aggregate tool-use count that excludes input content is recorded.

How BMR and calorie estimates are calculated

The tool applies a common BMR equation to age, height, weight and sex, then multiplies the estimate by an activity factor to approximate daily energy expenditure. These population-based formulas do not replace medical assessment or nutrition advice.

  • Activity factors are easy to overestimate; choose a lower level for mostly sedentary routines.
  • Adjust plans using longer-term measurements rather than one calculation.

FAQ

Are BMR and daily expenditure the same?

No. BMR estimates resting needs; daily expenditure also applies an activity multiplier.

Is the result medical advice?

No. It is a formula-based estimate; seek professional advice for medical conditions, pregnancy or specialized nutrition needs.

Why do calculators give different results?

They may use different equations, activity factors or units, so modest differences are expected.
