When you apply for life insurance, the price you’re quoted at the start isn’t necessarily the price you’ll pay. What you actually pay depends on the rate class the insurance company places you in after reviewing your health, lifestyle, and other risk factors — a process called underwriting. Understanding how rate classes work can help you know what to expect, and what you can do to land in the best possible class.

What Underwriting Is and Why It Exists

Underwriting is the process an insurance company uses to evaluate how much risk you represent before deciding whether to offer coverage, and at what price. Life insurance is priced on averages — actuaries calculate the expected cost of insuring large groups of similar people, and underwriting is how the company figures out which group you actually belong to. Without underwriting, healthy people would end up subsidizing higher-risk applicants through flat, one-size-fits-all pricing. Underwriting is what allows healthier applicants to get lower rates, and it’s also what allows the company to offer coverage at all to people with more significant health histories, just at an adjusted price.

The Typical Rate Class Tiers

While the exact names and criteria vary by carrier, most companies that fully underwrite policies use a similar tiered structure, roughly from best pricing to highest. Preferred Plus (sometimes called Preferred Best or Elite) is generally the top tier, reserved for applicants in excellent health with no significant family history of early disease, ideal build, and no tobacco use. Preferred is a step below — still very good health, but perhaps with a minor factor that keeps someone out of the top tier. Standard Plus and Standard cover applicants with average health for the general population — perhaps some controlled health conditions, a slightly elevated build, or other minor risk factors. Most insured Americans land somewhere in the Standard tiers.

Below Standard, applicants with more significant health conditions or risk factors may still qualify for coverage but at an increased cost, generally through one of two mechanisms. A table rating (sometimes labeled Table A through Table J, or Table 1 through Table 16 depending on the carrier) prices the policy as a percentage above the Standard rate — for example, a Table 2 rating might mean roughly 50% more than Standard, with each table typically adding another increment. A flat extra is a different mechanism: instead of a percentage increase applied to the whole premium, it’s a flat additional dollar amount charged per thousand dollars of coverage, often used for a specific identifiable risk, like a hazardous hobby or a past medical event, and sometimes structured to fall off after a set number of years (a temporary flat extra) rather than lasting the life of the policy.

What Factors Move You Between Classes

Underwriters weigh a combination of factors. Personal health history — conditions like high blood pressure, diabetes, high cholesterol, past cancer, or heart disease — is often the biggest driver, along with how well-controlled a condition is and how long ago it occurred. Family health history matters too, particularly whether close relatives had certain conditions at a young age. Tobacco and nicotine use (including vaping and even occasional cigar or chewing tobacco use) almost always moves an applicant to a separate, higher-priced set of tables regardless of how healthy they otherwise are. Build — the ratio of height to weight, sometimes supplemented with waist measurements — is evaluated against carrier-specific charts. Driving record, including DUIs or multiple moving violations, and hobbies like scuba diving, aviation, or motor racing can also add rating. Finally, occupation matters for jobs with elevated on-the-job risk.

Practical Tips to Get the Best Possible Offer

A few practical steps can meaningfully improve where you land. Avoid all nicotine products for at least the period a carrier requires to be considered a non-smoker — often 12 months, though this varies. Don’t make major health changes right before applying — starting a new medication, scheduling a procedure, or beginning treatment for a newly discovered condition right before underwriting can complicate your file; if you know a change is coming, it’s often worth discussing timing with your agent first. Be completely honest on the application — misrepresenting your health or habits can lead to a denied claim later, which defeats the entire purpose of having the policy, and most applications include a contestability period during which the insurer can investigate. Finally, consider timing around health improvements — if you’re actively working on lowering blood pressure, losing weight, or getting a condition under control, it may be worth waiting a few months for lab work and records to reflect that progress before applying, since underwriters generally look at your most recent and stable data.

Remember: Every Carrier Is Different

One of the most valuable things an independent agent can do is shop your specific situation across multiple companies, because rate class definitions, table rating scales, and how heavily any one factor is weighted all vary from carrier to carrier. A health history or build that lands in a lower tier with one company might qualify for a better class with another. That’s exactly why it rarely pays to assume the first quote you see reflects the best available offer for your situation.
