## Quick Answer

Estimate how many calories you burn per day based on your age, sex, weight, height, and activity level. Use your TDEE to set calorie targets for weight loss or muscle gain.

## Definition

A Total Daily Energy Expenditure (TDEE) calculator estimates how many calories a person uses in a day by predicting basal metabolic rate (BMR) and multiplying it by an activity factor. This calculator implements one equation, Mifflin-St Jeor, and applies one of five activity multipliers from 1.2 to 1.9. The output is a prediction from population data rather than a measurement of an individual's expenditure, and it is commonly used as a starting reference point for maintenance, deficit and surplus calorie planning.

## How to Use

1. **Enter your basic info** — Type your age, sex, height, and weight in either metric or imperial units.
2. **Select your activity level** — Choose from sedentary, lightly active, moderately active, very active, or extremely active based on your weekly exercise.
3. **Read your TDEE** — View your Total Daily Energy Expenditure in calories per day. This is the rough amount you burn daily.
4. **Adjust for your goal** — Read the figures the panel shows above and below maintenance. They are plain addition and subtraction against the estimate, not recommendations: intake below maintenance produces a deficit and intake above it produces a surplus.

This calculator provides estimates for educational and planning purposes. Always consult a qualified professional for specific advice on financial, medical, legal, or other regulated decisions.
