How "excess" weight is defined
The top of the healthy weight range is the weight that produces a BMI of 25 for your height. This calculator compares your current weight against that ceiling. Anything above it is reported as excess weight relative to the healthy band; if you are at or below the ceiling, the excess is zero.
It also shows your current BMI so you can see how far the number sits above the 25 threshold that marks the start of the overweight category.
Reading the breakdown
The pie chart splits your weight into the portion that fits within the healthy maximum and any excess above it. When you are inside the healthy range the chart is a single slice, which is the result you want to see.
Excess is shown in both kilograms and pounds. It represents the gap to the top of the healthy range, not a target you must reach all at once — gradual change is usually more sustainable.
Context for the number
Treat the excess figure as one signal among several:
- BMI ignores muscle, so very muscular people can read as overweight while lean.
- Waist measurement and body-fat estimates add useful detail.
- Where fat is carried matters as much as how much there is.
- Trends over weeks and months mean more than a single reading.
Health note
This calculator is a general guide based on BMI, not personalised medical advice. Weight goals should account for body composition, fitness and overall health. Speak with a doctor or dietitian before starting a weight-loss plan.
Formula
maxHealthy = 25·height²; excess = max(0, weight − maxHealthy)
