How It Works
The calculator estimates your Total Daily Energy Expenditure (TDEE) and suggests a caloric surplus needed for healthy weight gain.
📏 Formula Used:
Calories Needed = TDEE + Caloric Surplus
For example, if your daily TDEE is 2,500 calories and you aim to gain 0.5 kg (1 lb) per week, you need an extra 500 calories per day, totaling 3,000 calories daily.
Weight Gain Recommendations Table
| Goal Weight Gain | Extra Calories Needed Per Day | Expected Weekly Gain |
|---|---|---|
| 0.25 kg (0.5 lb) | 250 calories | ~0.25 kg (0.5 lb) |
| 0.5 kg (1 lb) | 500 calories | ~0.5 kg (1 lb) |
| 0.75 kg (1.5 lb) | 750 calories | ~0.75 kg (1.5 lb) |
| 1 kg (2 lbs) | 1000 calories | ~1 kg (2 lbs) |
📌 Note: A safe and sustainable weight gain rate is 0.25–0.5 kg (0.5–1 lb) per week. Gaining too quickly may lead to excess fat storage instead of muscle gain.

FAQs
What is Zeta Calculator used for? Zeta Calculator is a fun and informative tool that provides general estimates for weight-related calculations. While we work hard to ensure accuracy, these calculations should be treated as rough guidelines rather than definitive medical advice.
How accurate are the calculations? While we strive for precision, many factors affect individual weight changes that cannot be accounted for in a general calculator. Results should be considered estimates only.
How many calories are needed for weight gain? Generally, a surplus of approximately 7000 calories is associated with gaining 1 kg of body weight. This means consuming 500-1000 extra calories daily might lead to gaining about 0.5-1 kg per week. However, individual results can vary significantly based on metabolism, activity level, and other factors.
Can I maintain my current weight? Weight maintenance typically involves balancing calorie intake with energy expenditure. The exact numbers vary for each person based on factors like age, activity level, metabolism, and overall health.
How quickly can weight changes occur? Weight change rates vary significantly between individuals. Factors affecting this include:
- Current health status
- Activity level
- Metabolic rate
