What's My BMI? And Could It Save You Money on Life Insurance?

Body Mass Index (BMI) is a simple, widely used tool that helps gauge whether your weight falls within a healthy range for your height. Health professionals, including those at NSW Health, rely on it as a quick way to assess body weight in relation to height and identify potential health risks.

Understanding BMI Categories

Underweight: BMI less than 18.5

Normal weight (Healthy): BMI 18.5 to 24.9

Overweight: BMI 25 to 29.9

Obese: BMI 30 or higher

These categories come directly from reliable sources like NSW Health and align with broader Australian health guidelines.

While BMI isn't perfect—it doesn't account for muscle mass, age, gender, or body composition—it's a straightforward starting point for understanding your weight status.

Why BMI Matters for Life Insurance

When you apply for life insurance (such as life cover, total and permanent disability, or critical illness policies), insurers evaluate various factors, including your BMI.

• A higher BMI can sometimes lead to higher premiums or loadings due to increased health risks.

• On the flip side, maintaining a healthy BMI can unlock real savings.

Several insurers offer premium discounts—often lifetime—for applicants in certain BMI ranges at the time of application. These rewards recognise lower risk profiles and encourage healthier lifestyles. Common eligibility ranges around a BMI of 18.5 to 28.5 (or similar, like 19 to 28/29 depending on the insurer).

Discounts can range from 7.5% to 10% or more on premiums, sometimes up to 15%. Some require non-smoking status or no medical loadings, and others pair it with wellness programs. These are often applied automatically if you qualify during underwriting.

Note that exact ranges, discount percentages, and conditions vary by insurer and can change over time—always check current policy details or speak with a financial adviser or insurer directly.

The key takeaway:

A BMI in the healthy to moderate range can translate to noticeable, ongoing savings on your insurance premiums.
