Calculate

The Bulking Calories Calculator helps you determine how many calories you should consume daily to gain muscle mass. It takes into account:

• Weight, height, and age
• Gender
• Activity level
• Bulking calorie surplus

It calculates your TDEE (Total Daily Energy Expenditure) and adds a surplus to support muscle growth.

🔹 Formula Used

Step 1: Calculate BMR (Basal Metabolic Rate)

Mifflin-St Jeor Equation:

• Male: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age + 5
• Female: BMR = 10 × weight(kg) + 6.25 × height(cm) - 5 × age - 161

Step 2: Calculate TDEE TDEE=BMR×ActivityFactorTDEE = BMR × Activity FactorTDEE=BMR×ActivityFactor

Step 3: Add Bulking Surplus BulkingCalories=TDEE×(1+Surplus%)Bulking Calories = TDEE × (1 + Surplus\%)BulkingCalories=TDEE×(1+Surplus%)
