Calorie & TDEE Calculator
Last Updated: 8 April 2026
What is Calorie & TDEE Calculator?
The Mathematical Formula
BMR (Men) = (10 × weight) + (6.25 × height) - (5 × age) + 5 BMR (Women) = (10 × weight) + (6.25 × height) - (5 × age) - 161 TDEE = BMR × Activity Multiplier
📊 Practical Example
"A 30-year-old male weighing 80kg at 180cm height has a BMR of ~1,780 kcal. With moderate exercise (1.55x), his TDEE is ~2,760 kcal/day. To lose weight safely, he should target ~2,260 kcal/day."

Frequently Asked Questions
Q.What is TDEE?
TDEE stands for Total Daily Energy Expenditure. It represents the total amount of calories you burn in a 24-hour period, accounting for your Basal Metabolic Rate (BMR), exercise, and non-exercise movement.
Q.How accurate is the Calorie Calculator?
The Mifflin-St Jeor equation used here is considered the gold standard for healthy adults. However, factors like body fat percentage and metabolic health can cause slight variations.
Q.Should I eat below my BMR?
Generally, no. Eating below your BMR for extended periods can slow your metabolism and cause nutritional deficiencies. It's safer to target a deficit from your TDEE while staying near your BMR.
Q.How many calories are in 1kg of fat?
Consuming a deficit of ~7,700 calories roughly equates to 1kg of fat loss. A daily deficit of 500-1000 calories is usually recommended for sustainable weight loss of 0.5kg to 1kg per week.
