What Drives the Premium?
Life insurance rates are set by underwriting teams who assess the likelihood that a policyholder will die during the term. The core calculation combines actuarial tables, medical data, and individual risk factors into a single premium amount.

Key Risk Variables
Insurers evaluate several categories: age, gender, smoking status, medical history, and family disease patterns. Each factor carries a specific multiplier that adjusts the base rate.
Health and Medical Evidence
Recent medical exams, laboratory results, and physician reports inform the insurer's view of a applicant's current health. Conditions such as hypertension or diabetes increase risk and raise premiums.
Lifestyle and Occupation
High‑risk jobs (e.g., pilots, construction workers) or hobbies (skydiving, scuba diving) add to the risk profile. Non‑smokers and those who exercise regularly typically receive lower rates.
Policy Structure and Coverage Amount
Term life insurance is generally cheaper than whole life because it covers only a set period. The death benefit size also scales the premium: a $1 million policy costs more than a $200 000 policy.
Actuarial Modeling
Actuaries use mortality tables and statistical models to estimate expected payouts. The insurer's expense load, profit margin, and regulatory requirements are then added to produce the final premium.
Comparative Table of Typical Rate Influencers
| Factor | Effect on Premium | Typical Adjustment |
|---|---|---|
| Age | Higher age increases risk | +10% per decade after 30 |
| Smoking | Significant health risk | +50%–200% |
| Medical Condition | Specific diagnoses add risk | +5%–30% per condition |
| Occupation | Job hazard level | +0%–20% |
Final Premium Determination
After compiling all data, the underwriting team calculates the base premium, adds insurer overhead, and applies any discounts (e.g., for non‑smokers, bundled policies). The result is the monthly or annual payment the policyholder must make to maintain coverage.
