Calculate Your Total Daily Energy Expenditure
Our TDEE Calculator estimates your daily maintenance calories by combining your BMR with your activity level, providing a complete picture of your energy needs.
What is a TDEE Calculator?
A Total Daily Energy Expenditure (TDEE) Calculator estimates the total number of calories you burn each day. It starts by calculating your Basal Metabolic Rate (BMR)—the energy you burn at rest—and then adds the calories burned through physical activity. This final TDEE number represents your 'maintenance calories,' or the amount of energy you need to consume to stay at your current weight. It's the most important starting point for any weight loss, gain, or maintenance plan.
How It Works: BMR × Activity
The calculator follows a two-step process:
1. Calculate BMR using the Mifflin-St Jeor formula.
2. TDEE = BMR × Activity Multiplier (e.g., 1.2 for sedentary, 1.55 for moderate activity).
Frequently Asked Questions
What is TDEE?
TDEE stands for Total Daily Energy Expenditure. It is an estimation of how many calories your body burns per day when exercise is taken into account. It is calculated by first finding your Basal Metabolic Rate (BMR) and then multiplying that value by an activity multiplier.
How is TDEE calculated?
TDEE is calculated using the formula: TDEE = BMR × Activity Level Multiplier. Our calculator first finds your BMR using the Mifflin-St Jeor equation and then applies the appropriate multiplier based on the activity level you select (from sedentary to very active).
Why is TDEE important for weight management?
Your TDEE is your 'maintenance calories.' Knowing this number is crucial for weight management. To lose weight, you need to consume fewer calories than your TDEE (a caloric deficit). To gain weight or muscle, you need to consume more calories than your TDEE (a caloric surplus).
