Goal Calorie Calculator


Achieving your weight goals, whether it’s weight loss, maintenance, or gain, is greatly influenced by your daily calorie intake. Our Goal Calorie Calculator is a simple and efficient tool that can help you determine the right amount of calories to consume each day based on your specific weight goal and activity level. In this article, we will explain how to use this calculator effectively and provide insights into the science behind it.

Formula for Calculating Goal Calories

The Goal Calorie Calculator is based on a simplified approach to estimate your daily calorie intake. The formula can be summarized as follows:

  1. Calculate the total weight loss or gain needed, which is the difference between your current weight and your goal weight.
  2. Multiply this weight change by 7700, which is an approximate number of calories needed to lose or gain 1 kg of body weight.
  3. Divide the result by your chosen timeframe in weeks.
  4. Further adjust the outcome by your selected activity level.

How to Use

Our Goal Calorie Calculator is user-friendly and can be easily utilized by following these steps:

  1. Enter your current weight in kilograms.
  2. Input your goal weight in kilograms.
  3. Specify the timeframe in weeks within which you want to achieve your weight goal.
  4. Choose your activity level from the activity level dropdown menu, ranging from sedentary to extremely active.
  5. Click the “Calculate” button.

The calculator will instantly compute the daily calorie intake needed to reach your specified weight goal.


To better understand the calculator’s functionality, consider an example. Let’s assume you currently weigh 80 kg and your goal is to reach 70 kg in 12 weeks. You have a moderately active lifestyle with an activity level of 1.55. Using the formula provided:

  • Current Weight: 80 kg
  • Goal Weight: 70 kg
  • Timeframe: 12 weeks
  • Activity Level: 1.55

The calculation would be as follows:

  1. Weight Loss Needed = 80 kg – 70 kg = 10 kg
  2. Total Weight Loss in Calories = 10 kg * 7700 calories/kg = 77,000 calories
  3. Daily Calorie Intake = 77,000 calories / 12 weeks = 6,416.67 calories/week
  4. Daily Calorie Intake with Activity Level = 6,416.67 calories/week / 1.55 = 4,147.74 calories/day

So, your daily calorie intake for achieving the weight goal of 70 kg in 12 weeks with moderate activity is approximately 4,147.74 calories.
