Calorie Deficit How To Calculate


A calorie deficit is a fundamental concept in weight management, and it involves consuming fewer calories than your body needs to shed excess weight. Calculating your daily calorie deficit is an essential step towards achieving your weight loss goals. This Calorie Deficit Calculator guide will help you understand how to calculate the daily calorie deficit needed to reach your target weight.


The formula for calculating your daily calorie deficit is relatively simple. It takes into account the number of calories needed to lose 1 kilogram of weight, which is approximately 7700 calories.

Calorie Deficit = (Current Weight – Target Weight) * 7700 / (Number of Weeks * 7)

This formula allows you to determine the daily calorie deficit required to reach your desired weight within a specific time frame. Please note that individual results may vary based on factors such as metabolism and physical activity levels.

How to Use

Using the Calorie Deficit Calculator is a straightforward process:

  1. Enter your current weight in kilograms.
  2. Input your target weight in kilograms.
  3. Specify the number of weeks you’d like to take to reach your target weight.
  4. Click the “Calculate” button.

The calculator will then display the daily calorie deficit you need to achieve your weight loss goal.


For example, if your current weight is 75 kg, and your target weight is 70 kg, and you want to reach this goal within 8 weeks, enter these values into the calculator. Click “Calculate,” and the tool will provide you with the daily calorie deficit required to achieve your goal.
