Gaining weight in a healthy and controlled way requires proper planning, especially for fitness enthusiasts, athletes, and bodybuilders. Simply eating more food is not enough; you need to understand how many calories your body needs and how much surplus is required for weight gain. Our Mass Gain Calculator helps estimate the calorie intake needed to gain body weight and muscle mass effectively.
This tool is useful for anyone trying to build muscle, improve physique, or increase body weight in a structured and healthy manner.
Instead of guessing your diet needs, this calculator gives a clear and practical guideline.

How Mass Gain Calculation Works
Step 1: Calculate Maintenance Calories

- High surplus = faster gain (more fat risk)
Step 3: Estimate Weight Gain
Weight gain depends on calorie surplus.
Example Calculation
Suppose:
- Age = 20
- Weight = 70 kg
- Height = 175 cm
