TDEE Calculator with Activity Level

About the TDEE Calculator with Activity Level

TDEE Calculator computes Total Daily Energy Expenditure — the number of calories you burn in a normal day including activity. It uses the Mifflin-St Jeor BMR equation (the most accurate for healthy adults) multiplied by a standard activity factor.

How to use

1. Select gender and enter age, weight (kg), height (cm).
2. Choose your activity level — sedentary through extra-active.
3. Click Calculate TDEE for maintenance and goal calories.

Benefits & key features

• Foundation for any nutrition plan — gain, cut or maintain.
• Shows daily calorie targets for five different goals.
• Transparent math: BMR and activity multiplier are both shown.
• Pairs with Protein Intake and Calorie Deficit for a full plan.

Pro tip

TDEE is a starting estimate. Track your weight for two weeks; if it's stable you're at maintenance; adjust by 100 kcal at a time.

Why choose toolsfy for Health & Fitness tools?

A BMI calculator that harvests your email address, a TDEE estimator that upsells coaching — the health-and-fitness web is riddled with dark patterns. toolsfy's tools compute the same peer-reviewed equations (Mifflin-St Jeor for TDEE, WHO BMI bands, U.S. Navy body-fat formula) without asking for anything more than the numbers needed to run the math.

Common use cases

• Personal trainers running quick BMI and body-fat estimates for new clients during their first consultation, with nothing logged or stored.
• Home cooks planning a short calorie-deficit cycle and wanting the daily target in plain numbers rather than a vague "app score".
• Patients preparing for a doctor's appointment by converting a mg/dL blood-sugar reading into mmol/L (or vice versa) before their consult.
