Calculator

Overweight calculator: find your BMI, WHO category, and how much weight sits above the healthy-range ceiling for your height, in metric or US customary units.

Your BMI
27.7
Overweight
WHO classification: Underweight <18.5 · Normal weight 18.5–24.9 · Overweight 25–29.9 · Obese ≥30. BMI does not account for muscle mass, bone density, or body composition.

Enter your height and weight to calculate BMI and see how far above the healthy weight range's ceiling your current weight sits.

How to Use the Overweight Calculator

Toggle Metric or US units, then enter height and weight — the result shows your BMI category and, if applicable, how far your current weight sits above the healthy range's upper edge.

The Healthy Weight Calculator answers "what's my target range?" This one answers the next question: how far off is my current weight from the top of that range? Same underlying WHO numbers, opposite direction — target range in one tool, gap to that range in this one.

BMI = kg ÷ m²
Healthy-Range Ceiling (kg) = 24.9 × Height(m)²
Excess = Weight − Ceiling (when Weight exceeds it)

When weight sits at or below that ceiling, there's no "excess" figure to show — the calculator says so plainly rather than forcing a negative number onto the screen.

The Same BMI Limitations Apply Here

Everything the site's BMI Calculator says about BMI's blind spots carries over unchanged: it can't tell muscle from fat, and it's less reliable for athletes, older adults, pregnant people, and anyone under 20. An "excess" figure here measures distance from a population-level line, not a personalized target — a strength athlete flagged this way isn't carrying that gap in body fat.

Two people can show an identical excess-weight number for very different reasons — different frames, different muscle mass, different life stage — which is exactly why this figure works better as a conversation starter with a professional than as a number to chase down on its own.

This tool is for general information, not medical advice. Talk to a doctor or registered dietitian about what your weight, BMI, or any body-composition figure means for you specifically.
