Bulking Calories Calculator

Updated on


















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%)

🔹 How to Use the Calculator

  1. Enter your weight, height, and age.
  2. Select your gender.
  3. Choose your activity level.
  4. Enter bulking surplus % (commonly 10–20%).
  5. Click Calculate to see your daily bulking calories.

🔹 Example Calculation

  • Weight = 70 kg
  • Height = 175 cm
  • Age = 25
  • Gender = Male
  • Activity = Moderately active (1.55)
  • Surplus = 15%

Result:
Daily Bulking Calories ≈ 2,850 kcal

This is the estimated calorie intake to gain muscle while minimizing fat gain.

🔹 Benefits of Using This Calculator

  • Provides a personalized calorie target for bulking.
  • Helps avoid excess fat gain during bulking.
  • Adjusts for activity level and age.
  • Supports effective muscle growth and nutrition planning.
