Real TDEE How it works

FREE TDEE CALCULATOR

Start with an estimate.
Then measure what actually happens.

This calculator gives you a starting estimate. Real TDEE is designed to improve on that starting point over time using your own weight and nutrition data.

Estimate your daily expenditure

For adults 18+. This is an estimate, not a direct metabolic measurement.

THE METHOD

A calculator is the beginning, not the answer.

We use the Mifflin-St Jeor equation for the starting resting-energy estimate. The activity multiplier estimates the rest of your day.

Later, Real TDEE will keep the formula estimate separate from your learned expenditure, which is based on what you record and what happens to your weight over time.

Designed for adults 18+. Not intended for pregnancy, breastfeeding, or medical nutrition treatment. If your health situation makes calorie targets unsafe or uncertain, use professional guidance.
