Our reverse BMI calculator helps you determine what weight you need to achieve your target BMI. Simply enter your height and desired BMI to calculate your goal weight.
Calculate Your Target Weight
BMI Categories
Underweight

Obese
30.0 or greater
About Reverse BMI Calculation
The reverse BMI calculator helps you determine what weight you need to achieve a specific BMI value. This is useful for setting weight goals based on BMI categories.
How It Works
The formula used is: Weight = BMI × (Height in meters)². For imperial units: Weight (lbs) = (BMI × Height in inches²) ÷ 703
Healthy BMI Range
According to WHO standards, a BMI between 18.5 and 24.9 is considered healthy for most adults. This calculator can help you find what weight would put you in this range.
Setting Healthy Weight Goals
Realistic Goals
Set achievable goals by aiming for a weight loss of 1-2 pounds (0.5-1 kg) per week. Gradual changes are more sustainable.
Personalized Approach
Remember that BMI is just one measure of health. Consider your body composition, fitness level, and overall health when setting goals.
Professional Guidance
Consult with healthcare professionals before starting any weight management program, especially if you have existing health conditions.

Understanding the Reverse BMI Calculator
The Reverse BMI Calculator is an innovative tool that works differently from a standard BMI calculator. While a traditional BMI calculator tells you your current Body Mass Index based on your height and weight, the Reverse BMI Calculator helps you determine what weight you need to achieve a specific target BMI.
How the Reverse BMI Calculator Works
The Reverse BMI Calculator uses the standard BMI formula but solves for weight instead of BMI:
Weight (kg) = Target BMI × [Height (m)]²
In the imperial system:
Weight (lbs) = (Target BMI × [Height (inches)]²) ÷ 703
Practical Applications of the Reverse BMI Calculator
The Reverse BMI Calculator serves several practical purposes:
- Setting Weight Goals: It helps individuals set realistic weight goals based on recognized health standards.
- Weight Management Planning: Healthcare professionals can use it to establish target weights for patients.
- Fitness Tracking: Athletes and fitness enthusiasts can determine optimal competitive weights.
- Health Improvement: People looking to move from an unhealthy BMI category to a healthier one can identify specific weight targets.
Setting Realistic BMI Targets
When using the Reverse BMI Calculator, it's important to set realistic and healthy targets:
- For most adults, a BMI between 18.5 and 24.9 is considered healthy.
- If your current BMI is significantly higher or lower than the healthy range, consider setting intermediate targets rather than aiming for dramatic changes all at once.
- A healthy rate of weight change is typically 0.5-1 kg (1-2 lbs) per week for weight loss, and slightly less for weight gain.
- Remember that BMI is just one health indicator and doesn't account for factors like muscle mass, body composition, or fat distribution.
Beyond the Numbers: Healthy Weight Management
While the Reverse BMI Calculator provides a numerical target, healthy weight management involves more than just reaching a specific number on the scale:
- Balanced Nutrition: Focus on a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats.
- Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity exercise per week, plus strength training activities.
- Behavioral Changes: Develop sustainable habits rather than following restrictive short-term diets.
- Mental Well-being: Maintain a positive relationship with food and your body throughout your weight management journey.
- Professional Guidance: Consider working with healthcare providers, registered dietitians, or certified fitness professionals for personalized advice.
Special Considerations for Different Populations
Different populations may need to consider additional factors when using the Reverse BMI Calculator:
- Athletes: May have higher muscle mass and lower body fat, potentially making standard BMI targets less relevant.
- Older Adults: May have different body composition and might benefit from slightly higher BMI targets (22-27) than younger adults.
- Pregnant Women: Should not use BMI for weight management during pregnancy; consult with healthcare providers for appropriate weight gain guidelines.
- Children and Adolescents: Require age and gender-specific BMI percentiles rather than adult BMI calculations.
- Different Ethnicities: Some research suggests that optimal BMI ranges may vary slightly for different ethnic groups.
Using the Results Responsibly
The weight calculated by the Reverse BMI Calculator should be used as a general guideline rather than an absolute target. When interpreting your results:
- Consider your individual health circumstances, body composition, and medical history.
- Focus on gradual, sustainable changes rather than rapid weight loss or gain.
- Use the calculator as one tool among many in your health management toolkit.
- Consult with healthcare professionals before making significant changes to your diet or exercise routine.
- Remember that health encompasses many factors beyond weight, including physical activity levels, nutritional status, mental well-being, and absence of disease.
Frequently Asked Questions About Reverse BMI Calculator
A Reverse BMI Calculator is a tool that calculates what your weight should be to achieve a specific BMI (Body Mass Index) value. Unlike a standard BMI calculator that determines your BMI based on your current height and weight, the Reverse BMI Calculator works backward—you input your height and desired BMI, and it tells you what weight would give you that BMI. This is particularly useful for setting weight goals based on health recommendations.
According to the World Health Organization (WHO), a BMI between 18.5 and 24.9 is considered healthy for most adults. If you're currently outside this range, it's often advisable to set intermediate targets rather than aiming for dramatic changes all at once. For example, if your BMI is 32, you might first aim for a BMI of 29, then 27, and so on. Always consult with a healthcare professional before setting weight goals, as individual health circumstances can affect what's appropriate for you.
The weight calculated by the Reverse BMI Calculator is mathematically accurate based on the BMI formula. However, it's important to understand that this calculation doesn't account for individual factors like body composition, muscle mass, or fat distribution. Two people of the same height and weight can have very different body compositions and health profiles. The calculated weight should be used as a general guideline rather than an absolute target, and ideally should be discussed with a healthcare provider who can consider your complete health picture.
The results from the Reverse BMI Calculator should be used as one tool in your overall health management strategy. If you're trying to reach a healthy weight, use the calculated weight as a general reference point, but focus on developing sustainable healthy habits rather than fixating on a specific number. This includes balanced nutrition, regular physical activity, adequate sleep, stress management, and regular health check-ups. If you're significantly above or below your calculated target weight, consider working with healthcare professionals to develop a personalized plan for reaching your goals safely and sustainably.
Athletes and individuals with high muscle mass should use the Reverse BMI Calculator with caution. BMI doesn't distinguish between muscle and fat, so athletes often have higher BMIs despite having low body fat percentages. For these individuals, other methods of body composition assessment (such as body fat percentage measurements) are typically more relevant for setting weight and fitness goals. Athletes should work with sports nutritionists, trainers, or sports medicine specialists to determine appropriate weight targets for their specific sport and body type.
While a BMI of 22 falls within the healthy range (18.5-24.9) and is often considered ideal by some health professionals, it's not necessary to aim for this exact number. The healthy BMI range encompasses a variety of body types and weights. What's most important is maintaining healthy habits and overall well-being, rather than achieving a specific BMI value. Some individuals may naturally maintain a BMI at the lower or higher end of the healthy range while being perfectly healthy. Focus on behaviors that promote health rather than fixating on a particular number on the scale or BMI calculation.
