The Tdee Calculator calculates Total Daily Energy Expenditure by combining BMR with activity level. This Tdee Calculator uses an established clinical or fitness formula to give you a personalised estimate in seconds. Results are for educational reference — for specific health decisions, discuss with your doctor.

The formula behind this calculator: TDEE = BMR x activity multiplier, ranging from 1.2 (sedentary) to 1.9 (extremely active). As a practical example: A BMR of 1,500 for someone moderately active (x1.55) gives a TDEE of about 2,325 calories. All results are calculated instantly in your browser — no data is stored or transmitted.
