Calorie Deficit Calculator

Calculate your daily calorie intake to achieve a calorie deficit for weight loss based on your Total Daily Energy Expenditure (TDEE) and desired deficit percentage. Enter your TDEE, select your deficit, and click Calculate to get your target calories.

How It Works

Input your TDEE (calories/day) using the keypad or keyboard. Select your desired deficit percentage (e.g., 10%, 20%, 30%), then click “Calculate” to view your target daily calorie intake. Share or embed the calculator using the provided buttons.

Formulas

Calorie Deficit Calculation:

Deficit (cal) = TDEE × (Deficit % / 100)

Target Calorie Intake = TDEE − Deficit

Important Notes

TDEE must be a positive integer.
Deficit percentages: 10% (mild), 20% (moderate), 30% (aggressive). A 20% deficit is often recommended for sustainable weight loss (500-1000 cal/day).
The keypad’s Clear button clears the TDEE input field.
