Life Insurance Fundamentals
Life insurance pays a death benefit to a beneficiary when the insured dies, providing financial protection against the economic loss of a human life. This chapter walks through the major product categories, how premiums are calculated, how cash value builds inside permanent policies, how applicants are classified by risk, and the business and estate planning uses for life insurance. Roughly fifteen out of every one hundred exam questions come from this material, so a solid grasp of term versus permanent, the universal life mechanics, and underwriting tools pays off heavily.
Term Life Insurance: Pure Protection
Term life provides a death benefit for a stated period — usually ten, twenty, or thirty years, or until a specified age such as 65 — and pays nothing if the insured survives the term. It is sometimes called pure insurance because no cash value builds up; every premium dollar buys current mortality protection and a share of company expenses. Level term keeps both the face amount and the premium constant for the term. Decreasing term keeps the premium level but reduces the face amount year by year, which fits a declining mortgage balance. Increasing term is rare and pairs with riders that add face amount as the insured ages. Annual renewable term (ART) starts cheap and is renewable each year at a higher premium based on attained age. Term is the least expensive way to obtain a large amount of pure death benefit when budgets are tight.
Renewability and Convertibility of Term
Two features make term policies far more useful than a simple promise to pay. A renewable provision lets the policyowner extend coverage for another term without giving new evidence of insurability, although the new premium reflects the older attained age. A convertible provision lets the policyowner exchange the term policy for a permanent policy — typically whole life or universal life — without a medical exam, again with no proof of insurability. The conversion period is usually limited (for example, the first ten policy years or before age 65). These features protect an insured whose health has deteriorated and who otherwise could not buy new coverage.
Whole Life Insurance: Permanent Coverage with Cash Value
Whole life is a permanent contract that promises to pay a death benefit whenever the insured dies, as long as premiums are paid, and builds a guaranteed cash value over time. Premiums are level and calculated to age 100 (or 121 under newer mortality tables); the early premiums are higher than the actual cost of insurance, and the excess is invested by the insurer to build reserves that fund the later years when mortality cost climbs. Ordinary or continuous-pay whole life is paid for the insured's lifetime. Limited-pay whole life concentrates the same lifetime coverage into fewer paying years — common variants are 10-pay, 20-pay, and paid-up at age 65 — which means higher annual premiums but earlier paid-up status. Single-premium whole life is paid in one lump sum and is fully paid up from day one.
Universal Life (UL): Flexible Premium, Adjustable Death Benefit
Universal life unbundles the three premium components — mortality charge, expense load, and interest credited — and shows them on each annual statement. The policyowner may, within limits, choose how much premium to pay and when, so long as the cash value remains large enough to cover the monthly cost of insurance. The death benefit can be set in two ways. Type I (Option A) is a level death benefit: as cash value grows, the pure insurance portion shrinks so the total payout stays the same. Type II (Option B) is an increasing death benefit: the policy pays the face amount plus the accumulated cash value, so the death benefit grows over time. Type II costs more because the net amount at risk does not decline. Interest credited to the cash value is tied to a declared rate, with a guaranteed minimum floor.
Indexed UL and Variable Life: Linking Cash Value to Markets
Indexed universal life (IUL) credits interest to the cash value based on the performance of a stock index such as the S&P 500, subject to a participation rate, a cap, and a guaranteed floor that prevents losses from a down market. The policyowner does not actually own shares; the insurer uses options to hedge the credited interest. Variable life and variable universal life (VUL) go further: the cash value is held in separate-account subaccounts that look like mutual funds, and the policyowner directs how it is allocated. Because the policyowner bears investment risk and gain, variable products are securities under federal law. A producer who sells variable life or VUL must hold a life insurance license AND a securities registration (FINRA Series 6 or 7) and deliver a prospectus to the prospect.
Specialty Forms: Survivorship, Endowment, and Modified
Several less common designs answer specific planning problems. A first-to-die joint life policy pays at the first death among two insureds and is sometimes used to fund a mortgage held by a couple. A second-to-die or survivorship policy pays only after both insureds have died, which makes premiums affordable and is used heavily for estate tax liquidity. An endowment policy traditionally paid the face amount at maturity (for example, age 65) or at death if earlier; almost all endowments now violate the federal definition of life insurance and lose tax advantages, so they are rare in modern markets. Modified whole life starts with lower premiums for the first few years and then steps up to a higher level, helping young buyers afford permanent coverage. Graded premium whole life works similarly, with the premium rising annually for a set period before leveling off.
How Premiums Are Calculated: Mortality, Interest, Expenses
Every life premium is built from three factors. Mortality is the projected cost of paying death claims, drawn from mortality tables that show how many of each one thousand insureds at a given age are expected to die during the next year. Interest is the earnings the insurer expects on the reserves it holds; a higher assumed interest rate lowers the premium because the company will need less from policyowners. Expenses include commissions to producers, taxes, salaries, and policy issue costs, all loaded onto the gross premium. Policyowners can pay annually, semi-annually, quarterly, or monthly, but the more frequent the mode, the higher the total annual outlay because of modal loading — a fee that compensates the insurer for lost interest and added billing costs.
Risk Classification and Underwriting Tools
Underwriting is the insurer's process for deciding whether to accept an applicant and at what price. Each applicant is placed in a risk class. Preferred Plus and Preferred are reserved for the healthiest, longest-lived applicants and receive the lowest rates. Standard is the average rate class. Substandard or rated applicants present higher-than-average mortality and pay a flat extra premium or a percentage table rating. Declined applicants are uninsurable, at least at this time. To reach these decisions the underwriter draws on a stack of tools: the written application, paramedical or full medical exam, an Attending Physician Statement (APS) from the applicant's doctor, a report from the Medical Information Bureau (MIB) that flags information disclosed on prior applications, an inspection report by a third-party investigator, a motor vehicle report (MVR), and drug or alcohol testing. The agent contributes the first layer of underwriting in the field by screening obviously poor risks and making sure the application is complete and accurate.
Insurable Interest, STOLI, and Replacement Concerns
Insurable interest is the legal foundation for buying life insurance on another person. A person has insurable interest in their own life, in a spouse or close relative, in a business partner, key employee, or someone owing them money. In life insurance, the interest must exist at the time the policy is issued, but it does not have to continue afterward — a divorced spouse, for example, may still hold a valid policy on the ex. California prohibits Stranger-Originated Life Insurance (STOLI) arrangements, where an investor convinces an insured to buy a policy with the intent of immediately transferring it to the investor for cash. STOLI lacks genuine insurable interest and is treated as wagering on a human life.
Business and Estate Uses: Key Person, Buy-Sell, ILIT
Life insurance solves several business and estate problems. Key person insurance is owned and paid by a business on the life of an employee whose death would damage the firm; the business is both owner and beneficiary, the employee is the insured, and the proceeds offset lost profits or the cost of replacing the worker. A buy-sell agreement makes sure that when an owner dies, the surviving owners can buy the deceased's share and the family receives cash instead of an unwanted business stake. In a cross-purchase plan, each partner owns a policy on every other partner; in an entity plan, the business itself owns one policy on each owner. For wealthy individuals, an Irrevocable Life Insurance Trust (ILIT) owns the policy and holds the proceeds outside the insured's taxable estate, providing liquidity to pay estate taxes and equalize inheritances between heirs who do and do not want family assets like a business or a farm.
