Reverse BMI Calculator – Find Your Target Weight for a Desired BMI

When you know the BMI (Body Mass Index) you want to achieve—say a healthy range—you can use a Reverse BMI Calculator to find out what your ideal weight should be for your height. Instead of calculating BMI from weight and height, this tool reverses the formula: you input your height and desired BMI, and it gives you the corresponding weight.

What Is a Reverse BMI Calculator?

A Reverse BMI Calculator is a tool that flips the usual BMI formula. Instead of:

BMI = weight ÷ (height²)

you use:

weight = BMI × (height²)

So if you know your height and the BMI you aim to achieve (for example, 22, 24, or some target healthy number), the calculator tells you what your weight needs to be to match that BMI. CountCalculate.com+1

This helps you set realistic weight goals instead of just guessing or relying on general weight charts.

Why Use a Reverse BMI Calculator?

Goal Setting: If you want a BMI in the “healthy” range (e.g. 18.5–24.9), this tells you the weight to aim for.
Personalized Targets: Different heights require different weights to reach the same BMI.
Clarity: Instead of converting your current weight into BMI and then estimating, this gives direct feedback.
Motivation & Planning: Helps in diet, fitness, and wellness planning by giving a clear target.

How It Works — Behind the Scenes

Input your height (in meters, cm, feet/inches, etc.).
Enter your target BMI (for example, 20, 22, 23.5).
The calculator uses the formula: Target Weight = Target BMI × (Height)² — if height is in meters, weight result is in kilograms.
You’ll get your ideal weight for that BMI.

Different units (metric or imperial) are handled internally by conversions. Calculator Academy+1

Example Use Case

Height: 1.70 m
Desired BMI: 22

Calculation:

Weight = 22 × (1.70)² = 22 × 2.89 = 63.58 kg

So to have a BMI of 22 at 1.70 m tall, your weight should be ~63.6 kg.

Limitations & Considerations

BMI is only a rough guide. It doesn’t distinguish between muscle mass vs fat, body composition, or fat distribution.
Health factors matter. Some people may be healthy outside the “ideal BMI” range depending on body type, medical conditions, etc.
Use with other measures. Waist circumference, body fat percentage, and fitness levels are also important indicators of health.
Consult professionals. Always check with doctors, nutritionists, or fitness experts before making big weight changes.
