When you apply for life insurance, one of the first things an insurer does is evaluate your overall health and lifestyle to assign you a risk classification — commonly called a “life insurance class.” This classification directly determines your premium. The better your class, the lower your monthly payment. The difference between classes can be dramatic: two people buying the same $500,000 policy at the same age might pay wildly different amounts based on nothing more than their health profile.
Here’s what you need to know about how it all works — and what you can actually do about it.
The Main Life Insurance Classes
Insurers vary slightly in their naming conventions, but most use a tiered system that looks something like this:
Preferred Plus (or Elite/Super Preferred) is the top tier. These are the best rates available, reserved for people in exceptional health with a clean family history, no tobacco use, ideal weight, and low-risk lifestyle habits. Only a small percentage of applicants qualify.
Preferred is the second-best tier. You’re in excellent health, but perhaps you have one minor issue — slightly elevated cholesterol controlled by medication, or a family history of heart disease that doesn’t disqualify you outright. Most healthy adults who maintain good habits can realistically aim for this class.
Standard Plus is a step above average. You may have some mild health concerns that are well-managed, or you’re at the high end of the acceptable BMI range. Your rates will be noticeably higher than Preferred, but still reasonable.
Standard is the baseline for a healthy adult. Many people fall here simply due to average weight, slightly elevated blood pressure, or a family history with a few red flags. This is where the majority of applicants land.
Substandard (Table Ratings) applies when your health profile presents elevated risk. Insurers use a “table rating” system — Table A through Table J, or Table 1 through 10 depending on the company — where each table step adds a percentage (usually 25%) to the Standard rate. Someone with a serious chronic condition, a history of cancer, or a recent heart attack might fall here. Coverage is still available; it just costs more.
Tobacco/Smoker Classes run parallel to the above tiers. If you use tobacco or nicotine in any form, you’ll be placed in a smoker class, which typically means rates two to three times higher than a non-smoker equivalent. Most insurers also have smoker substandard tiers for tobacco users with additional health concerns.
What Insurers Actually Look At
During the underwriting process — which for most traditional policies involves a medical exam — insurers are evaluating a specific set of factors. Understanding these helps you know where you stand before you even apply.
Medical history is the foundation. Underwriters review your records going back years, looking at diagnoses, hospitalizations, prescriptions, and how well conditions are managed. Conditions like well-controlled type 2 diabetes or hypertension may only drop you one class; poorly managed or multiple conditions can push you into substandard territory.
Blood and urine tests reveal things you might not even know about yourself — cholesterol levels, glucose, liver and kidney function, and any signs of tobacco or drug use. Your numbers matter more than just having or not having a diagnosis.
Family history carries real weight, particularly for heart disease, cancer, stroke, and diabetes. Underwriters look at first-degree relatives (parents and siblings) and pay close attention to whether those relatives were young when they were diagnosed or died. A parent who had a heart attack at 45 is more concerning than one who had it at 75.
Height and weight (BMI) are a factor at every insurer. Most have build tables showing the maximum and minimum weights for each classification at a given height. Being significantly above or below ideal range affects your class, sometimes significantly.
Occupation and hobbies matter more than people expect. If you’re a commercial fisherman, logger, or pilot, your occupational risk may affect your rates. Avocational risks like scuba diving, skydiving, rock climbing, and motorsports can add flat extra charges or even lead to exclusions.
Driving record is reviewed, particularly for DUIs, reckless driving charges, and multiple moving violations in recent years.
Mental health history is considered, though practices vary. Serious conditions or hospitalizations within a certain window may affect classification; well-managed anxiety or depression with medication and therapy usually has minimal impact.
What You Can Control
Here’s the encouraging news: many of the factors that determine your class are modifiable. If you have flexibility on when you apply, the following can genuinely improve your outcome.
Stop using tobacco and wait. Most insurers require you to be tobacco-free for 12 months before qualifying for non-smoker rates; many require two to three years for their top-tier non-smoker classes. The rate difference is so significant that if you’re planning to quit anyway, it’s worth timing your application accordingly.
Improve your bloodwork. Cholesterol, blood glucose, and blood pressure are the big three. In the months before applying, focus on diet, exercise, and compliance with any prescribed medications. Work with your doctor to get your numbers into an optimal range. These metrics are measured fresh at your exam and can absolutely move your classification.
Lose or gain weight to hit a more favorable build table. Insurers publish build charts, and there are specific weight thresholds that determine what class you qualify for. If you’re a few pounds above the cutoff for Preferred Plus, getting into that range before your exam could save you thousands over the life of the policy.
Time your application strategically after a health event. If you recently recovered from surgery, completed cancer treatment, or were diagnosed with a chronic condition, waiting until you’re further from that event can improve your odds. Many health events require a certain number of years in remission or stable management before they stop affecting your classification significantly.
Choose a safer hobby — or at least hold off on disclosing a new risky one. This isn’t about being deceptive; it’s about timing. If you’ve been casually thinking about taking up skydiving but haven’t actually done it, applying before you start means the insurer can’t rate you for it.
Shop around. Different insurers weigh the same risk factors differently. One company may be very competitive for well-controlled diabetics; another might be more favorable to people with cardiac family history. An independent broker who works with multiple carriers is invaluable here — they know which companies “specialize” in rating your particular health profile favorably.
What You Can’t Control
Honesty is critical here. The factors below are real, they will be discovered during underwriting, and misrepresenting them on an application is grounds for a policy being rescinded — potentially leaving your family without the benefit when they need it most.
Age is the most fundamental pricing factor in life insurance, and there’s nothing to be done about it. Rates increase every year you wait, and the increase accelerates significantly after about age 50. The single best time to buy life insurance is as young and healthy as you can manage.
Genetics and family history are what they are. You can’t change who your parents were or what they died from. You can, however, make sure that your own health management (treating the conditions you may have inherited) is in the best shape possible.
Pre-existing conditions — particularly serious ones like a prior heart attack, stroke, certain cancers, or Type 1 diabetes — will affect your class. The question isn’t usually whether they’ll be rated, but how and by how much. This is where working with a broker who knows which carriers are most favorable for your condition pays off.
Certain occupations are unavoidable risks. If your career involves significant physical danger, some insurers will add charges or decline coverage. Others are more lenient. The best approach is finding the right carrier rather than expecting any single insurer to overlook your occupation.
Prior declinations can follow you. If you’ve been declined for individual coverage in the past, many insurers ask about it, and prior declines can complicate your next application. This is another reason to work with a knowledgeable broker who can match you to the right carrier the first time rather than shotgunning applications.
Practical Tips for Getting Your Best Rate
Think about your application as a performance you can prepare for. Know your numbers — blood pressure, cholesterol, glucose, BMI — before your exam. Take your exam in the morning, fasted, well-hydrated, and after a good night’s sleep. Avoid strenuous exercise 24 hours before, as it can temporarily affect certain lab values. Review your prescription history and be ready to explain all medications, since gaps or inconsistencies raise questions.
Get help. An independent life insurance broker costs you nothing (they’re compensated by the insurer) and can save you significantly by matching your health profile to the carrier most likely to give you the best class.
They can also do informal pre-screenings with underwriters at different companies before you formally apply, which protects your record from unnecessary declines.
Finally, don’t wait for “someday.” Every year you delay is a year older you are when you apply, and one more year during which something could change in your health — moving you from Preferred Plus to Standard, or from Standard to a table rating. The best class you’ll ever qualify for is the one available to you today.
