Free TDEE Calculator - Calculate Your Daily Calorie Needs
Calculate your Total Daily Energy Expenditure to find out how many calories you burn each day.
Formula & Methodology
This calculator estimates your Basal Metabolic Rate using the Mifflin-St Jeor equation, then multiplies it by an activity factor to determine your Total Daily Energy Expenditure — the total calories you burn in a day including exercise.
- BMR (Mifflin-St Jeor) = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5 (men: +5, women: -161)
- TDEE = BMR × Activity Multiplier
Worked Example
Using the TDEE Calculator: apply the formula above to your input values. For instance, BMR (Mifflin-St Jeor) = (10 × weight in kg) + (6.25 × height in cm) - (5 × age in years) + 5 (men: +5, women: -161), then TDEE = BMR × Activity Multiplier. The tool performs each step instantly and shows the result.
Frequently Asked Questions
What is TDEE?
Total Daily Energy Expenditure is the total calories you burn in a day, including your resting metabolism and all activity.
How is TDEE calculated?
It estimates your BMR with the Mifflin-St Jeor equation, then multiplies by an activity factor from sedentary to very active.
How do I use TDEE for weight goals?
Eat below TDEE to lose weight and above it to gain; matching it maintains your current weight.
