- View Calorie TargetsReview your maintenance TDEE and customized calorie targets for weight loss or muscle gain.
Achieving sustainable weight loss, building lean muscle mass, optimizing athletic performance, or maintaining a healthy body composition requires understanding your body's daily energy expenditure. The human body burns calories continuously through Basal Metabolic Rate (BMR—energy expended at complete rest), the Thermic Effect of Food (TEF), and Physical Activity Level (NEAT and exercise).
The EtoolMitra Calorie Calculator (Daily TDEE & BMR Maintenance) utilizes clinically validated metabolic equations—including the Mifflin-St Jeor Formula and the Harris-Benedict Equation—to compute your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE). By entering your age, biological gender, height, current weight, and weekly physical activity level (from sedentary office worker to intense athlete), the calculator determines your precise daily maintenance calorie baseline.
The tool generates customized daily calorie and macronutrient targets (Proteins, Carbohydrates, and Fats) tailored to specific body goals: Mild Weight Loss (0.5 lb/week - 250 calorie deficit), Standard Weight Loss (1.0 lb/week - 500 calorie deficit), Extreme Fat Loss (2.0 lb/week - 1000 calorie deficit), Weight Maintenance, and Lean Muscle Hypertrophy (+300 to +500 calorie surplus).
With dual Imperial and Metric unit support, visual macro breakdown charts, and practical nutrition guidelines, EtoolMitra provides a dependable, science-backed roadmap for your fitness and nutrition journey.

Frequently Asked Questions
Quick answers about Calorie Calculator: Daily TDEE & BMR Maintenance, formats, and specifications.
What is TDEE vs BMR?
BMR (Basal Metabolic Rate) is the calories your body burns at complete rest to survive. TDEE (Total Daily Energy Expenditure) is your total calories burned per day including physical activity and daily movement.
How many calories should I eat to lose 0.5 kg (1 lb) per week?
To lose 0.5 kg per week, aim for a daily calorie deficit of approximately 500 calories below your maintenance TDEE.
Is Calorie Calculator: Daily TDEE & BMR Maintenance completely free to use?
Yes, this tool is 100% free with no registration, no hidden subscriptions, and no usage limitations.
