How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

TDEE = BMR × activity multiplier. BMR (Basal Metabolic Rate) is calories at complete rest; multiply by your activity level (1.2–1.9) to get daily calorie needs. Eating at TDEE maintains current weight.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

How is TDEE different from BMR?

BMR is calories burned at rest. TDEE multiplies BMR by an activity factor to account for daily movement, exercise, and non-exercise thermogenesis.
