How to use TDEE Calculator

Enter the body measurements and activity level, and the calculator will estimate total daily calorie use beyond rest alone.

What this calculator is for

This calculator is for maintenance-calorie planning and weight-management starting points. Unlike BMR, TDEE is meant to include daily movement and activity, so it is often the more practical number for ordinary meal planning.

Tips

Activity level drives the result strongly, so choose the option that matches your actual week, not your best week.
TDEE is still an estimate, and body weight trends are the best way to fine-tune it over time.
Maintenance intake can drift when sleep, stress, training load, or routine change, so revisit the estimate when life changes.

Method used

The calculator first estimates BMR with Mifflin–St Jeor, then multiplies that result by the selected activity factor to estimate total daily energy expenditure.

TDEE = BMR × activity factor.
Activity factors used here: sedentary 1.2, light 1.375, moderate 1.55, very active 1.725, extra active 1.9.
BMR is calculated with the same adult Mifflin–St Jeor equation used in the BMR calculator.
