Reverse BMI Calculator – Fast & Accurate BMI Reverse Calculation

Reverse BMI Calculator helps you work out the exact weight needed to achieve a target BMI based on your height. Unlike a regular BMI calculator, which takes your height and weight to find your BMI, a BMI reverse calculator does the opposite. It starts with your desired BMI and height, then calculates your required weight in both kilograms and pounds.

This tool is useful for setting fitness goals, tracking body composition, and understanding your BMI equation in detail. Whether you want to reverse calculate BMI for health reasons or simply learn how to calculate reverse BMI, this guide and calculator will give you accurate results instantly.

Frequently Asked Questions (FAQ) about the Reverse BMI Calculator

1. What is a Reverse BMI Calculator?

A Reverse BMI Calculator is a tool that helps you find the weight you need to achieve a specific BMI based on your height. Unlike a standard BMI calculator, which calculates BMI from your weight and height, the BMI reverse calculator works backward — starting with your desired BMI to give you the target weight in kilograms and pounds.


2. How do you perform BMI reverse calculation manually?

The BMI reverse calculation uses the BMI equation in reverse:

Weight (kg)=BMI×Height (m)2

To do this manually:

  1. Convert your height to meters.

  2. Square your height.

  3. Multiply the squared height by your target BMI.
    For example, if you are 1.7 m tall and your target BMI is 22, the calculation is: 22 × (1.7²) = 63.6 kg.


3. Is the BMI calculator reverse method accurate?

Yes, the BMI calculator reverse method is accurate for calculating target weight based on the BMI equation. However, BMI alone does not measure body fat percentage, muscle mass, or overall health. For more precision, you can use a BMI to body fat calculator alongside the reverse BMI calculation.


4. Who should use the reverse calculate BMI tool?

The reverse calculate BMI tool is useful for:

  • People setting weight loss or gain goals.

  • Athletes needing to meet a BMI requirement.

  • Individuals tracking progress for health checkups.

  • Anyone curious about how to calculate reverse BMI for better fitness planning.


5. How is the reverse BMI calculator different from a regular BMI calculator?

A regular BMI calculator takes your weight and height to find your BMI. The reverse BMI calculator starts with your height and target BMI to determine your ideal weight. This makes it ideal for planning and goal setting, rather than just assessing current status.
