What BMI is considered overweight?

For adults, BMI 25.0 to 29.9 is commonly categorized as overweight, and BMI 30 or above is categorized as obesity.

Why include waist circumference?

BMI does not show fat distribution. Waist circumference can add context for central adiposity and cardiometabolic risk, but it still does not diagnose disease by itself.

Is BMI 22 the ideal weight?

No. BMI 22 is only a reference point inside the adult healthy-weight range. A suitable goal depends on health history, body composition, symptoms, and clinician guidance when needed.

Overweight Calculator

Check adult BMI category, healthy-weight range, weight above BMI 24.9, waist context, and 5% and 10% weight-loss markers.

Adult Overweight Screening

This calculator estimates adult BMI category, the weight difference to the upper healthy-weight boundary, and practical 5% and 10% weight-loss markers. Waist circumference is included as an optional context signal.

BMI = \frac{weight _{k g}}{height _{m}^{2}}

Adult body mass index formula.

weight_{24.9} = 24.9 \times height_{m}^{2}

Weight at the upper adult healthy-weight boundary.

Why 5 Percent And 10 Percent Are Shown

CDC guidance commonly uses gradual, sustainable weight loss and notes that modest weight loss can improve health markers. The 5% and 10% markers are planning references, not mandatory goals.

weight_{- 5%} = 0.95 \times current weight

Five percent weight-loss marker.

Not a treatment recommendation

The calculator does not diagnose obesity, prescribe calories, or recommend medication, surgery, or a specific diet.
