カロリー過剰計算機

1日のカロリー過剰量と増量目標達成までの推定週数を計算。

はじめに

Calorie Surplus Calculator — Calculate your daily calorie surplus and estimated weeks to reach a weight-gain goal. Enter TDEE (kcal/day), Target calories/day, Goal weight gain (lb) to get an instant, accurate result.

計算式

Daily surplus = target calories − TDEE. Weeks to goal = (goal gain in lb × 3500) / (weekly surplus), using the same 3,500 kcal ≈ 1 lb approximation.

ステップごとの説明

  1. Enter the TDEE (kcal/day).
  2. Enter the Target calories/day.
  3. Enter the Goal weight gain (lb).
  4. Click Calculate to see your result instantly.

実例

Example: With TDEE (kcal/day) = 2200, Target calories/day = 2700, Goal weight gain (lb) = 10, the Calorie Surplus Calculator gives Daily Surplus: 500, Weekly Surplus: 3500, Weeks To Goal: 10.

よくある質問

How big should my surplus be for lean gains?
A modest surplus of around 200–300 kcal/day is generally recommended to minimize fat gain while building muscle.
Will all the weight gained be muscle?
No — a surplus alone doesn't guarantee muscle; resistance training is needed to direct the extra calories toward muscle rather than fat.
What inputs does the Calorie Surplus Calculator need?
You'll need to provide: TDEE (kcal/day), Target calories/day, Goal weight gain (lb). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Calorie Surplus Calculator?
The Calorie Surplus Calculator applies the formula exactly as calculated — Daily surplus = target calories − TDEE. Weeks to goal = (goal gain in lb × 3500) / (weekly surplus), using the same 3,500 kcal ≈ 1 lb approximation. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is this a medical diagnosis?
No. The Calorie Surplus Calculator provides an estimate based on standard formulas and general population data, not a medical diagnosis or personalized clinical advice. Individual results can vary — consult a doctor or other qualified healthcare provider for medical concerns.
Is the Calorie Surplus Calculator free to use?
Yes, the Calorie Surplus Calculator is completely free, requires no signup, and runs instantly in your browser.

カロリー過剰計算機について

The Calorie Surplus Calculator uses a real, verifiable formula — Daily surplus = target calories − TDEE. Weeks to goal = (goal gain in lb × 3500) / (weekly surplus), using the same 3,500 kcal ≈ 1 lb approximation. — so results are accurate every time, not an approximation.
