What Underwriting Actually Is
Underwriting is the process an insurance company uses to assess how much risk you represent before issuing a policy and setting your premium. The insurer is essentially answering one question: given everything known about this applicant, how likely is a claim, and how large might it be?
Age is one input — it correlates strongly with mortality risk — but it is far from the only one. Insurers collect a range of information to build a fuller picture of your health, lifestyle, and personal history. Understanding those factors helps you anticipate how your application will be evaluated and why two people the same age can pay very different premiums.
Before applying, it can help to work through key questions about your coverage needs so you enter the process informed.
Underwriting
The process an insurer uses to evaluate an applicant's risk level, determine eligibility for coverage, and set the premium. It involves reviewing health, lifestyle, financial, and personal history information.
Risk Class
A category assigned to an applicant after underwriting that reflects their overall risk level. Your risk class directly determines your premium rate — the healthier and lower-risk your profile, the better your classification.
Flat Extra
An additional premium charge, expressed as a fixed dollar amount per thousand dollars of coverage, added because of a specific elevated risk such as a hazardous occupation or high-risk hobby.
Table Rating
A substandard risk classification applied when an applicant's health or history raises their risk above the standard level. Each table step increases the premium by a percentage above the standard rate, commonly 25% per table.
Paramedical Exam
A brief medical examination, typically conducted at your home or workplace by a licensed health professional hired by the insurer, that collects measurements and blood or urine samples used in underwriting.
MIB (Medical Information Bureau)
A member-owned organization that maintains a coded database of health information reported by insurers on previous applications. Insurers use MIB reports to verify application accuracy and detect inconsistencies.
Key Factors Underwriters Evaluate
Underwriters use a combination of the information you provide and records they pull independently. Here are the main categories they examine:
| Primary underwriting factors | Age, health history, current health, lifestyle, occupation, family history |
| Typical exam required | Paramedical exam (blood, urine, blood pressure, height/weight) |
| Tobacco impact | Smokers are placed in a separate rate class, typically paying significantly more than non-smokers |
| Table rating increment | Each substandard table step commonly adds ~25% above the standard premium |
| No-exam options | Simplified-issue and guaranteed-issue policies skip underwriting but carry limits on coverage amounts |
Health History
Your medical records — obtained through the MIB, pharmacy records, and attending physician statements — reveal past diagnoses, chronic conditions, surgeries, and prescribed medications. Conditions such as diabetes, heart disease, or a history of cancer are significant rating factors, though their impact depends on severity, treatment history, and how well the condition is managed.
Current Health Measurements
Most traditional policies require a paramedical exam: height, weight, blood pressure, and lab results (blood and urine). Your BMI and whether lab results flag conditions like elevated cholesterol or blood glucose directly influence your risk classification.
Lifestyle and Habits
Tobacco use is one of the most significant premium drivers outside of age itself. Smokers are typically placed in a separate rate class. Beyond tobacco, underwriters may also consider heavy alcohol use and participation in high-risk activities such as private aviation, rock climbing, or scuba diving.
Occupation and Hobbies
Certain jobs — commercial fishing, mining, or work at significant heights — carry elevated occupational risk. Similarly, some hobbies trigger an additional premium charge, called a flat extra, added on top of the standard rate.
Family Medical History
Hereditary conditions matter. A family history of early-onset cardiovascular disease or certain cancers can affect your classification even if you are currently healthy.
Driving Record and Criminal History
Multiple DUIs or serious moving violations signal elevated risk. A felony conviction can make coverage harder to obtain or result in a higher premium.

Always read policy documents carefully and consult a licensed insurance professional for guidance specific to your situation.
Risk Classifications and What They Mean for Your Premium
After reviewing all available information, underwriters assign each applicant to a risk class. While terminology varies by insurer, most companies use a tiered structure along these lines:
- Preferred Plus / Super Preferred: Excellent health, clean records, no significant risk factors. Lowest available premiums.
- Preferred: Good health with minor issues such as slightly elevated cholesterol that is well-controlled.
- Standard Plus / Standard: Average health for age; some medical history or mild risk factors present.
- Substandard (Table Rated): Notable health conditions or risk factors; premiums are charged at a percentage above standard — each "table" typically adds 25% to the standard rate.
Some applicants are declined entirely if the risk is considered uninsurable by the carrier. In those cases, a guaranteed-issue policy — which skips underwriting — may be an option, though these products carry lower death benefits and higher premiums per dollar of coverage.
Your Application Must Be Accurate
Life insurance applications ask about health and lifestyle in detail, and your answers are verified against medical records, pharmacy databases, and the MIB. Misrepresenting information — intentionally or accidentally — can result in a denied claim or policy rescission. Review every question carefully and disclose fully. If you are unsure how to answer something, ask a licensed agent before submitting.
If you are wondering whether your current coverage amount still makes sense, explore common reasons existing coverage falls short. Once you have a policy in hand, learning how to read the policy document ensures you understand exactly what you are paying for.
