How underwriters sort term applicants into risk classes

When two people the same age apply for the same $500,000 term policy and receive very different prices, the difference is almost never random. An underwriter has sorted each of them into a risk class, based on measurements and history, and the price follows the class. This post explains how that sorting works in practice: which facts go in, how they combine, what the labels mean, what a "table rating" and a "flat extra" add to a price, and which parts of the picture you can still change before you apply.

What a rate class is

A rate class is a pricing group. The insurer looks at the risk that you will die during the term and puts you in a group whose members it expects to die at about the same rate, then charges every member of that group the same price for the same age, sex, amount and term. The national tradition is to name the groups with words like preferred plus, preferred, standard plus and standard for nonsmokers, with separate tobacco versions and a substandard or "rated" range below. The names, the number of tiers, and the cutoffs between them differ from company to company. One insurer's "preferred" is another's "standard plus."

The guide on life insurance rate classes: preferred plus to substandard describes the tiers. This post is about the process that assigns them.

Two points to keep in mind throughout:

1. A class is a judgment about a pattern, not a diagnosis. An underwriter is not rating your health in a medical sense. She is estimating, from a table of past outcomes, how people with your combination of measurements have fared.
2. Insurers differ. Each company writes its own guidelines, and a measurement that costs you a tier at one company may not at another. That is why two quotes can differ even when the application is identical.

The inputs, one by one

Underwriters draw on several sources. The specifics depend on the insurer and the amount applied for, but the categories are consistent. Larger amounts and older ages generally bring more requirements; see the general explanation in underwriting.

Build

Height and weight are combined into a build category. Insurers publish tables, called build charts, that show the range of weights for each height that fit each class. Both too heavy and, at the extreme, too light can matter. Build charts are usually stricter for the top classes than for standard. The guide on life insurance, weight and build charts has more.

What you can influence: weight is the most changeable input for many applicants, but only over months. A weight change in the last week before an exam will not help, and a sudden large change can raise questions.

Blood pressure and cholesterol

An examiner or a lab measures your blood pressure and your cholesterol, and many insurers require a blood and urine sample for larger amounts. The cutoffs for the best classes are narrower than medical "normal." A reading that your doctor calls fine may land you in standard instead of preferred. Treated conditions are not penalized the same way at every company: some insurers look at readings on medication, others look at the history of the condition. See what a life insurance blood and urine test looks for for what the lab looks for.

What you can influence: the conditions under which the measurement is taken. Follow the instructions the examiner gives you before the visit, commonly about fasting and about avoiding things like heavy exercise or caffeine beforehand. Those instructions come from the paramedical company and the insurer, so use their wording, not a rule of thumb from an article.

Personal medical history

The application asks about diagnoses, hospital stays, surgeries, tests ordered, and medications. Records from the last several years carry the most weight. A single resolved event can matter less than a repeating pattern. Insurers also check prescription databases and the MIB file for history that confirms or contradicts your answers; see how insurers check your prescription history and The MIB report: what insurers know about your history. A medication can reveal a condition you did not mention, which is a reason to answer completely.

What you can influence: you cannot change the past, but you can answer accurately, gather dates and the names of treating doctors before the call, and pick the timing of the application relative to a recent event. Some events, such as a recent surgery, lead insurers to postpone, so ask an agent before you apply.

Family history

Insurers ask about parents and siblings who died or were diagnosed with certain conditions, typically heart disease, certain cancers and some hereditary conditions, before a stated age. The guide on how family medical history affects life insurance describes how this is used. A strong family history can cost a tier in the top classes, and it matters more when it appears alongside other risk factors.

What you can influence: nothing about the history itself. Answer to the best of your knowledge, ask a relative if you are unsure, and say "unknown" where it is unknown.

Tobacco and nicotine

Tobacco use is the single largest class divider. Cigarettes, cigars, chew, vaping and sometimes nicotine replacement can place you in a tobacco class, and insurers test for nicotine in the lab for many applications. Rules about how long you must be nicotine-free differ by company. The related guide is how quitting smoking lowers life insurance rates.

What you can influence: the time since you last used nicotine. This is often the only factor that moves your price by a large amount.

Driving, occupation, avocations and travel

A record of DUIs or serious violations, a hazardous job, dangerous hobbies such as private flying or racing, and travel to certain places can add surcharges or exclusions. These usually show up as a flat extra rather than a lower class.

Financial and other context

For larger amounts, insurers check that the coverage fits your income and need. That affects the amount offered, not the class.

How the inputs combine

Underwriting is not a weighted average in which a good number cancels a bad one. Most insurers set the class by the worst qualifying factor, or by a points system in which several moderate findings add up. A common structure looks like this:

This table is a simplification; each insurer's actual rules are more granular and are not public. The practical implication is that a single item, such as a blood pressure reading or a recent hospitalization, can cap your class regardless of how good the rest of the file is. When an applicant says "I'm healthy and got a bad price," the explanation is often one item.

Table ratings and flat extras

Below the standard range, an insurer may still offer coverage at a higher price. It does this in two ways, explained in detail in table ratings and flat extras explained.

A table rating adds a percentage to the standard premium. A common convention steps up in increments of 25 percentage points of extra mortality, so a rating labeled Table 2 corresponds to about 150% of standard mortality, and the premium rises by roughly half. The rating normally lasts for the policy term, although some companies will review it after a period of stable health.

A flat extra adds a fixed dollar charge per $1,000 of coverage for a number of years, often because of a hazard, such as flying a private plane, or a time-limited issue, such as a recent procedure.

Here is a hypothetical comparison with invented numbers. A 45-year-old applies for $500,000 of 20-year term.

The flat extra line deserves the arithmetic. $1.50 per $1,000 on $500,000 is 500 times $1.50, or $750 a year, which is $62.50 a month. Add that to $40 and the premium is $102.50. These are not prices, only a demonstration of how each surcharge works.

If you receive an offer with a rating, ask what caused it and whether it can be reviewed later; asking for a better rate class later explains how to ask.

What you can influence before you apply

The earlier you start, the more you can do. A few examples, none of which is a guarantee.

1. Time since nicotine. If you recently quit, ask each insurer what its required nicotine-free time is, and consider waiting if you are close.
2. Weight and blood pressure trends. If you are near a build or blood pressure cutoff, steady changes over several months show in your doctor's records and in the exam.
3. Pending medical events. If a test, procedure or medication change is scheduled, ask an agent whether to apply before or after.
4. Conditions of the exam. Schedule a morning appointment if fasting is required, follow the instructions you receive, and bring a list of medications and doctors.
5. Complete, accurate answers. A discrepancy between your answers and your records can result in a worse class and a later problem on a claim.
6. Several insurers. Guidelines differ. An independent agent or broker can submit the same facts to more than one company, and some applicants can request an informal preview from an underwriter before a formal application. Whether that is possible depends on the agent and the company.

Two things you cannot influence are your age and your family history, so do not spend effort there. Related reading from this blog on the next steps is a lower rate class than quoted: accept, negotiate or walk away and a 12-month plan to qualify for a better life insurance rate class.

Two applicants, one afternoon

This is a hypothetical to show how the pieces interact. Elena and Tom are both 42, both nonsmokers, both applying for $500,000 of 20-year term. Every number below is invented.

Elena has a build within the top range, a blood pressure reading of the kind that qualifies for the best class, no prescriptions and no family history in the categories the application asks about. Her lab results are in range. The underwriter has no reason to move her down, so she is offered the top class.

Tom is also in good health, but three things differ. His weight is a few pounds above the top-class limit on the insurer's build chart. His blood pressure was slightly high at the exam, which he later learned happens to him around medical visits. And his father had a heart attack at 58. Any one of these might cost a tier. Together they place him in standard.

Neither result is a judgment on their health. Now suppose Tom waits six months, loses the few pounds, and has a home blood pressure log his doctor can document. His father's history will not change, and the insurer may treat it as the deciding factor either way. A different insurer might weigh that history less heavily and place him higher from the start. That is why Tom's best move may be to have an independent agent send the same file to several companies at once, rather than assume that the first answer is the only one.

If the price gap between the classes in his quote is $8 a month, the cost of standard over twenty years is $8 times 240 months, or $1,920. If the gap is $25 a month, it is $6,000. The larger the gap, the more it pays to try.

What the amount and age change

The requirements are not the same for every applicant. A few patterns are worth knowing.

• Larger amounts bring more testing. Insurers commonly ask for a blood and urine sample, an exam, or medical records above certain amounts, and the thresholds rise or fall with age.
• Older applicants get more scrutiny. The same reading at 60 means something different from the same reading at 30, because the table of outcomes is different.
• Accelerated or no-exam programs use other data. Some insurers use prescription history, motor vehicle records and similar sources to decide without an exam. The class assigned can be lower than a full exam would have produced, or the price can be higher. See accelerated underwriting: approval without an exam for how those programs work.

What to do if the offer is worse than the quote

Quotes online are often based on the best class, and the offer reflects what underwriting found. That gap is common and is not necessarily a sign of an error.

• Ask the agent for the specific reason for the class.
• Ask whether the decision can be reconsidered with new information, such as a letter from your doctor or a repeat lab result.
• Compare the offer against a second insurer before accepting or declining.
• Check the premium against the coverage you need; a rated policy can still be the right choice if the alternative is no coverage.
• Before you walk away, remember that an insurer may report an application and its outcome to the MIB, so a later application elsewhere can see it.

Key takeaways

• A rate class is a pricing group assigned by an underwriter from build, blood pressure, cholesterol, personal and family history, tobacco use and other factors, and each insurer sets its own cutoffs.
• One item can cap your class, so a single borderline reading or event often explains a price that seems out of line with your overall health.
• Table ratings add a percentage to the standard premium; flat extras add a fixed amount per $1,000 of coverage, often for a limited time.
• Time since nicotine, weight trends, exam conditions and the timing of the application are the factors you can still influence.
• Answer accurately, compare several insurers, and ask what drove a rating so you can seek a review later.
