Overweight Calculator
Free Overweight Calculator: Check BMI, Healthy Weight & Excess Weight
The Overweight Calculator is a powerful online tool designed to help you determine whether your current weight falls within a healthy range based on your height, gender, and Body Mass Index (BMI). This calculator quickly analyzes your body measurements and shows whether you are underweight, normal weight, overweight, or obese according to standard BMI guidelines.
In addition to calculating BMI, this tool also estimates your healthy weight range, overweight threshold, obesity threshold, ideal average weight, and the amount of excess weight above a healthy BMI. It helps users understand how much weight they may need to lose or gain to achieve a healthier body composition.
This calculator uses internationally recognized BMI formulas and ideal body weight equations such as Devine, Robinson, Miller, Hamwi, Lorentz, Peterson, and Broca methods. By combining these formulas, the calculator provides more balanced and realistic weight recommendations for both men and women. The ideal average shown in the results is the average of these seven formulas and the weight at BMI 22.
The Overweight Calculator is useful for people starting a weight loss journey, fitness enthusiasts tracking progress, healthcare professionals, gym trainers, and anyone who wants to better understand their body weight status. Whether your goal is fat loss, maintaining a healthy lifestyle, or improving overall health, this tool provides quick and reliable insights.
The calculator supports multiple measurement units including centimeters, feet, inches, kilograms, and pounds, making it easy to use worldwide. It also displays target weights for BMI 22 and BMI 25, which are commonly used as healthy BMI goals. Age does not change the BMI result, but for anyone under 18 the calculator adds a note, because adult BMI categories do not apply to children and teenagers.
Quick answer: a man who is 170 cm tall and weighs 85 kg has a BMI of 29.4, which is in the overweight range. The weight at a BMI of 25 for that height is 72.2 kg, so the excess weight is about 12.8 kg. Enter your own height and weight above for your personal result.
What Is Overweight?
Overweight is a condition where a person's body weight is higher than the recommended healthy range for their height. It is commonly measured using Body Mass Index (BMI), which compares body weight to height.
A BMI between 25 and 29.9 is generally classified as overweight, while a BMI of 30 or higher is considered obese. Being overweight may increase the risk of several health conditions including diabetes, high cholesterol, heart disease, high blood pressure, fatty liver disease, and joint pain.
However, BMI is not a perfect measurement because it does not distinguish between muscle and body fat. Athletes and muscular individuals may have a higher BMI without having excess fat. That is why this calculator also provides additional weight analysis and healthy weight targets.
How BMI Is Calculated
BMI is calculated by dividing your weight in kilograms by your height in meters squared. BMI categories are generally classified as underweight below 18.5, normal weight 18.5 to 24.9, overweight 25 to 29.9, and obese 30 or higher.
The weights below show what these categories mean for someone who is 170 cm tall:
| Category | BMI | Weight at 170 cm |
|---|---|---|
| Underweight | Below 18.5 | Below 53.5 kg |
| Normal weight | 18.5 – 24.9 | 53.5 – 72.0 kg |
| Overweight | 25 – 29.9 | 72.2 – 86.4 kg |
| Obese | 30 or higher | 86.7 kg or more |

Is BMI Always Accurate?
BMI is a useful screening tool, but it may not always accurately measure body fat percentage. Muscular individuals may have higher BMI values despite having low body fat. Similarly, older adults may have normal BMI but lower muscle mass. For best results, BMI should be considered together with body fat percentage, waist measurements, physical activity, and overall health. The body fat calculator can help with that.
Why Maintaining Healthy Weight Matters
Maintaining a healthy body weight can improve energy levels, mobility, heart health, blood sugar control, sleep quality, and overall well-being. Being overweight may also increase the risk of high blood pressure, diabetes, heart disease, sleep apnea, joint problems, and reduced mobility. A balanced diet, regular physical activity, proper sleep, and stress management all play important roles in achieving and maintaining a healthy weight. To plan your daily energy needs, use the calorie calculator.
