Overweight Calculator
Find the kilograms and percentage by which you are above your ideal weight range for height.
About the Overweight Calculator
Overweight Calculator tells you how many kilograms you are above the upper limit of the WHO healthy-weight band for your height — and what percentage that excess represents. The healthy band is computed as BMI × (height ÷ 100)2 with the standard healthy BMI range of 18.5–24.9. If your current weight exceeds the 24.9 cap, the tool reports the excess in kilograms and as a percentage above the upper-ideal weight; if you fall inside the band, it tells you so; if you are below the lower bound, it flags potential under-weight. Use it as a quick screening tool — for athletes with high muscle mass, body-fat percentage is a more accurate marker.

Pro tip
If the report says you are below the lower-ideal weight, please consult a clinician — under-weight can be a sign of underlying nutritional issues. BMI is a screening tool; body-fat percentage is more precise for athletes.
