Male Female



Losing weight often involves a balance between the calories you consume and those you burn. The “How Many Calories a Day to Lose Weight Calculator” is a valuable tool that helps individuals determine the optimal daily calorie intake to achieve their weight loss goals. Understanding this calculation can contribute significantly to a successful weight loss journey.


The fundamental formula for determining daily calorie intake for weight loss is based on creating a calorie deficit. The formula is:

Calories for Weight Loss=Total Daily Energy Expenditure (TDEE)−Caloric Deficit 

The Total Daily Energy Expenditure represents the number of calories your body needs to maintain its current weight, and the Caloric Deficit is the reduction in calories necessary to lose weight.

How to Use?

  1. Input Your Information: Provide details such as age, gender, weight, height, and activity level into the calculator.
  2. Select Weight Loss Goal: Specify the desired rate of weight loss, typically ranging from 0.5 to 2 pounds per week.
  3. Calculate: Click the calculate button to determine your recommended daily calorie intake for weight loss.


Let’s consider an example:

  • Age: 30
  • Gender: Female
  • Weight: 150 pounds
  • Height: 5 feet 6 inches
  • Activity Level: Moderately active
  • Weight Loss Goal: 1 pound per week

TDEE=BMR×Activity Multiplier  Caloric Deficit=500×Weight Loss Goal (in pounds per week)

After calculating TDEE and Caloric Deficit, subtract the Caloric Deficit from TDEE to determine the recommended daily calorie intake for weight loss.
