Fat Burning Calculator

Losing fat effectively isn’t about extreme dieting or endless cardio—it’s about understanding how your body uses energy. A proper fat loss plan starts with knowing how many calories you burn, how much you should eat, and how to balance your nutrients correctly.

The Fat Burning Calculator is a complete body analysis and fat loss planning tool. It helps you calculate your BMI, BMR, TDEE, daily calorie target, calorie deficit, weekly fat loss, and macronutrient breakdown based on your body data, activity level, and fat loss goal.

Whether your goal is slow, sustainable fat loss or a more aggressive transformation, this calculator gives you realistic numbers you can actually follow.

What Is a Fat Burning Calculator?

A fat burning calculator estimates how much energy your body needs to function and how many calories you should consume to lose fat safely.

This calculator goes beyond basic calorie math by combining:

  • Body measurements
  • Activity level
  • Fat loss goals
  • Diet preferences

The result is a personalized fat loss roadmap, not just a number.

What This Calculator Measures

1. Body Mass Index (BMI)

BMI helps classify your weight status (underweight, normal, overweight, obese) based on height and weight.

2. Basal Metabolic Rate (BMR)

BMR is the number of calories your body needs at rest to maintain vital functions like breathing and circulation.

3. Total Daily Energy Expenditure (TDEE)

TDEE represents how many calories you burn per day based on your activity level.

4. Daily Calorie Target

This is your recommended calorie intake for fat loss, adjusted to stay safe and sustainable.

5. Daily Calorie Deficit

Shows how many calories you are cutting daily to achieve your chosen fat loss goal.

6. Weekly Fat Loss Estimate

Displays expected fat loss in both kilograms and pounds.

Based on your selected diet approach.
