Body Mass Index (BMI) is a key factor in life insurance underwriting, and being significantly overweight or obese can increase your premiums or affect your eligibility. Understanding how insurers use BMI helps you anticipate the impact on your application.
Each insurer has its own height-weight tables and build guidelines, which can vary significantly.
How Insurers Use BMI
Insurers use BMI as one indicator of health risk, combined with other factors like blood pressure, cholesterol, and family history. A BMI between 18.5 and 25 is considered normal, 25 to 30 is overweight, and over 30 is obese.
Most insurers offer Preferred rates up to a BMI of about 28 to 30 and Standard rates up to about 33 to 35. Above that, table ratings or declines become more likely.
When BMI Doesn’t Tell the Whole Story
BMI doesn’t distinguish between muscle and fat. Athletes and physically active people may have high BMIs due to muscle mass while being in excellent health. Some insurers take this into account with additional measurements or by giving more weight to other health indicators.
Your overall health profile matters more than BMI alone.
Strategies for Overweight Applicants
If your BMI puts you in a higher rate class, consider losing weight before applying — even 10 to 15 pounds can make a difference. Work with an independent agent who knows which insurers have the most generous build tables. Some companies are significantly more lenient with weight than others.
If you can’t improve your BMI, ensuring all other health markers are excellent can help offset the impact on your premium.
