The Life Insurance Health Classification System Explained

When you apply for life insurance, your insurer doesn't just ask if you're healthy — they assign you a specific health classification that directly determines your premium. These rating classes are the result of a detailed underwriting process that evaluates your medical history, lifestyle, and family health background. Understanding how this system works gives you a meaningful advantage before you ever fill out an application.

Most insurers use four core "standard" rating tiers, plus a tobacco-user track and a substandard/table rating system for higher-risk applicants. Here's how each class breaks down:

Only about 5% of applicants qualify for Preferred Plus — the most competitive classification available.

What Qualifies You for Each Rating Class

Underwriters evaluate a standardized set of health and lifestyle factors when placing you into a class. The criteria below reflect typical industry standards, though exact thresholds vary by carrier.

Preferred Plus / Elite

This is the top tier — and it's tough to earn. To qualify, you generally need:

• BMI between 18 and 29
• Blood pressure averaging no more than 136/86 over the past two years
• Total cholesterol between 120–300, with an HDL ratio no higher than 4.5
• No tobacco or nicotine use for at least 3–5 years
• No significant personal medical history (no major chronic conditions or hospitalizations)
• No immediate family members who died from heart disease or cancer before age 60
• Clean driving record — no more than 2 moving violations in the last 3 years, no DUIs
• No hazardous hobbies such as skydiving, private piloting, or motorsports

Preferred

This class is accessible to those in very good health with minor, well-controlled issues. You may have:

• Slightly higher cholesterol or blood pressure that is managed with medication
• A family history of disease, with no personal diagnosis
• Participation in a mildly risky occupation or sport (evaluated case-by-case)

Standard Plus

This class accommodates applicants who fall just outside the Preferred window. Common factors include mild overweight, a family member with early disease onset, or minor controlled conditions with otherwise clean labs.

Standard

The most common classification. Standard applicants may have:

• Controlled asthma, mild depression or anxiety, or a history of minor resolved illnesses
• Multiple prescriptions that are managed appropriately
• A non-ideal BMI or family history of chronic illness
• A few more driving violations or higher cholesterol levels

Standard vs. Preferred: How Much Does It Really Cost?

The financial difference between rating classes is significant — and compounds over the life of a policy. On average, each tier you move down adds roughly 15–25% to your premium. Between Preferred Plus and Standard, the gap can reach 30–50%.

Here's a real-world example for a $500,000, 20-year term policy for a 40-year-old male non-smoker:

Table Ratings: How High-Risk Applicants Are Priced

If your health profile doesn't meet Standard criteria, you won't necessarily be declined — you'll likely receive a table rating. This is a substandard classification that adds a percentage surcharge on top of the Standard rate.

Most insurers use a scale of Table 1 through 16 (or letters A through P), with each level adding approximately 25% to the Standard premium.

Tables 1–8 are the most commonly assigned. Tables beyond 8 reflect serious or multiple high-risk conditions. Common health conditions that typically result in table ratings include:

• Type 1 or Type 2 Diabetes — table rated unless perfectly controlled; uninsurable if A1C exceeds 10.1
• Heart disease or stroke history — table rated based on severity and time since event
• Sleep apnea — table rated unless compliant with CPAP treatment and well-managed
• Cancer history — may qualify for Standard or low table rating if in remission for 2+ years (basal cell skin cancer often excluded from penalization)
• Obesity — rated based on BMI and any associated complications
• Severe or ongoing mental health conditions — bipolar disorder, severe depression, or recent hospitalizations

Smokers and tobacco users are placed on a separate rating track entirely. Premiums for smokers can be 2 to 4 times higher than for non-smokers. Learn more about how tobacco use affects pricing in our guide on life insurance for smokers.

How to Improve Your Rating Class (And What to Do If You Disagree)

Steps to Take Before You Apply

The best time to work on your classification is before you submit an application. Here's what can make a measurable difference:

1. Quit tobacco — Most insurers require 12–24 months of nicotine-free status (verified via cotinine testing) to qualify for non-smoker rates. After 3–5 years, you may qualify for Preferred or better.
2. Lose weight — Wait at least 6–12 months after reaching your target BMI so underwriters see a sustained change, not a temporary fluctuation.
3. Manage blood pressure and cholesterol — Get labs done and work with your doctor. Bring those numbers into guideline range before applying.
4. Address driving history — Violations typically fall off your record within 3 years. If you've had a DUI, most carriers require at least 5 years before considering Preferred rates.
5. Limit risky hobbies — Disclosing participation in skydiving, private piloting, or motorsports will impact your rating. Some carriers offer exclusion riders instead of full table ratings.

How to Appeal a Rating Decision

If you receive a rating that seems too high, you have options:

• Request a formal review — Ask the insurer to reconsider, especially if you believe there was an error in how your medical records were interpreted.
• Submit additional documentation — Recent lab results, a letter from your physician, or documentation of treatment compliance can support a reclassification.
• Apply to a different carrier — Underwriting guidelines vary widely. A Standard or table rating at one insurer may qualify as Preferred Plus at another.
• Reapply after health improvements — If you've lost weight, quit smoking, or improved your health metrics, wait 6–12 months and reapply. Policies are underwritten at the time of application, so improvements made after approval don't change your existing premium — but they can unlock better rates on a new policy.

The life insurance underwriting process typically takes 4–8 weeks, giving you time to gather documentation and work with your agent if you want to challenge a preliminary decision.

Frequently Asked Questions

What is the difference between Preferred Plus and Standard life insurance?

Preferred Plus is the highest health rating class, reserved for applicants in exceptional health with ideal BMI, clean medical history, no tobacco use, and no significant family history of disease before age 60. Standard is the baseline class for average health, accommodating common controlled conditions like mild hypertension or asthma. The premium difference between the two can be 30–50% — translating to thousands of dollars in extra cost over the life of a 20-year term policy.

Can I get life insurance with a table rating?

Yes. Table ratings are specifically designed to extend coverage to higher-risk applicants who don't meet Standard criteria. You will pay more than someone classified as Standard — typically 25% more per table level — but you can still obtain meaningful coverage. Working with an independent broker significantly increases your chances of finding the most competitive table rating available for your specific condition.

How long after quitting smoking can I qualify for non-smoker life insurance rates?

Most insurers require you to be tobacco and nicotine-free for at least 12 to 24 months before qualifying for non-smoker rates, confirmed through a cotinine test during your medical exam. To reach Preferred or Preferred Plus classifications, most carriers require 3 to 5 years of documented nicotine-free status. If you quit recently, you can still get coverage now and reapply for better rates once you've met the timeline.

What health conditions automatically result in a table rating?

No single condition guarantees a specific outcome, but conditions commonly resulting in table ratings include Type 2 diabetes, heart disease, stroke history, sleep apnea (if untreated), obesity, significant mental health conditions, and certain cancer histories. The severity, duration, and level of management all influence where you land on the table scale. Cancer that has been in remission for 2+ years — especially basal cell skin cancer — may qualify for Standard or better at some carriers.

Can you appeal a life insurance health classification decision?

Yes. You can formally request a reconsideration from the insurer, typically by submitting additional medical documentation, recent lab work, or a letter from your treating physician. You can also apply to a different insurer, as underwriting guidelines vary significantly by company. If your health has genuinely improved, the most effective strategy is often to wait 6–12 months, document the changes, and reapply for a fresh policy at a potentially better rate.
