About the TDEE Calculator
huge search volume for fitness calculators; rankable with clean macro breakdown and goal-based calorie targetsThe TDEE Calculator is a free online fitness and health tool designed to calculate your Total Daily Energy Expenditure (TDEE) — the total number of calories your body burns each day — using the Mifflin-St Jeor equation for Basal Metabolic Rate (BMR) adjusted for your activity level. Instead of showing just a single number, this tool outputs three complete goal plans: Cutting (weight loss), Maintenance, and Bulking (muscle gain), each with target calories and a full macronutrient breakdown in grams of protein, carbs, and fat. To build a complete health picture, pair this with our BMI Calculator for body composition tracking, our Body Fat Calculator for body fat estimation, our Calorie Calculator for general daily needs, our Calorie Burn Calculator for exercise-specific expenditure, our Water Intake Calculator for hydration planning, or our Ideal Weight Calculator to set healthy target weights.
Enter your age, gender, height, weight, activity level, and optionally your body fat percentage. The tool instantly calculates your BMR using the Mifflin-St Jeor equation (10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5 for men, −161 for women), then multiplies by your activity factor to determine TDEE. Three calorie targets are computed: Cutting (TDEE − 500), Maintenance (TDEE), and Bulking (TDEE + 500), each with a customized macro split optimized for the goal. Cutting uses 35% protein / 35% carbs / 30% fat to preserve muscle, Maintenance uses 30/40/30 for balanced health, and Bulking uses 25/50/25 for muscle growth. Each goal card visualizes the macro distribution with color-coded progress bars. If you enter your body fat percentage, your lean body mass is displayed alongside the results. All calculations are based on clinically validated equations and run entirely in your browser.

Frequently Asked Questions
What is TDEE and why does it matter?
Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a day, including your basal metabolic rate (BMR — calories burned at rest), the thermic effect of food (digestion), and physical activity. Knowing your TDEE lets you set precise calorie targets: eat below TDEE to lose weight, at TDEE to maintain, and above TDEE to gain weight or build muscle.
What is the Mifflin-St Jeor equation?
The Mifflin-St Jeor equation is the most clinically validated formula for estimating BMR. For men: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age(y) + 5. For women: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age(y) − 161. It was developed in 1990 and is considered the gold standard for BMR estimation in healthy adults.
What macro split should I use for cutting vs bulking?
This tool uses evidence-based macro splits for each goal. Cutting (weight loss) uses 35% protein, 35% carbs, and 30% fat — higher protein preserves muscle mass during a calorie deficit. Maintenance uses 30% protein, 40% carbs, and 30% fat for balanced nutrition. Bulking (muscle gain) uses 25% protein, 50% carbs, and 25% fat — higher carbs fuel intense workouts and recovery. You can adjust these ratios based on your personal preferences and dietary needs.
How accurate is the body fat percentage input?
If you know your body fat percentage from DEXA scan, caliper measurements, or bioelectrical impedance, entering it provides a more complete picture by showing your lean body mass. However, it is optional — the TDEE and macro calculations work correctly without it. The BMR and TDEE formulas use total body weight, not lean mass, so body fat does not affect the calorie calculations.
How much weight will I lose/gain per week with these targets?
A deficit of 500 kcal/day (Cutting target) typically results in approximately 0.5 kg (1 lb) of weight loss per week. A surplus of 500 kcal/day (Bulking target) typically results in approximately 0.5 kg (1 lb) of weight gain per week. Individual results vary based on metabolism, adherence, exercise type, and other factors.
Should I use metric or imperial units?
Both are equally accurate. The tool automatically converts between metric (kg, cm) and imperial (lbs, ft/in) systems. Choose whichever you are most comfortable with. If you use imperial, enter your height in feet and inches (e.g., 5'9") and weight in pounds.
