How the Weight Gain Calculator Works

This tool estimates your TDEE (Total Daily Energy Expenditure) using your age, sex, height, weight, and activity level. Then it adds a realistic calorie surplus and sets macro targets to prioritize protein.

  • Maintenance (TDEE): Your estimated daily calories to maintain weight.
  • Surplus: +250 to +500 kcal/day for steady gain (adjust based on results).
  • Protein: Generally 0.8–1.0 g per lb bodyweight (or 1.8–2.2 g/kg).
  • Carbs & Fats: Split the remaining calories based on preference and training demands.

Pick a Smart Surplus

Choose a pace that fits your training and recovery. Bigger surpluses can add weight faster, but may increase body fat. Start conservative, review progress weekly, and adjust.

Goal Pace Suggested Surplus Expected Gain Best For
Lean & Steady +250 kcal/day ~0.25–0.5 lb/week Recomposition, minimal fat gain
Balanced +350–400 kcal/day ~0.5–0.75 lb/week Most lifters & active adults
Faster Gain +500 kcal/day ~0.75–1 lb/week Hardgainers, short bulks

Recommended Macros for Lean Weight Gain

Use protein as your anchor, then fill in carbs and fats to match performance and appetite.

  • Protein: 30–50 g per meal; hit your daily target first.
  • Carbs: Fuel training and recovery (more around workouts).
  • Fats: Round out calories; emphasize quality sources.

Tip: If appetite is low, use more calorie-dense meals (healthy fats, carb add-ons) to hit your surplus without feeling stuffed.
