The insurer (the life insurance company) calculates the policy prices with intent to fund claims to be paid and administrative costs, and to make a profit. The cost of insurance is determined using mortality tables calculated by actuaries. Actuaries are professionals who employ actuarial science, which is based in mathematics (primarily probability and statistics). Mortality tables are statistically-based tables showing expected annual mortality rates. It is possible to derive life expectancy estimates from these mortality assumptions. Such estimates can be important in taxation regulation.
The three main variables in a mortality table have been age, gender, and use of tobacco. More recently in the US, preferred class specific tables were introduced. The mortality tables provide a baseline for the cost of insurance. In practice, these mortality tables are used in conjunction with the health and family history of the individual applying for a policy in order to determine premiums and insurability. Mortality tables currently in use by life insurance companies in the United States are individually modified by each company using pooled industry experience studies as a starting point. In the 1980s and 90's the SOA 1975-80 Basic Select & Ultimate tables were the typical reference points, while the 2001 VBT and 2001 CSO tables were published more recently. The newer tables include separate mortality tables for smokers and non-smokers and the CSO tables include separate tables for preferred classes.

Recent US select mortality tables predict that roughly 0.35 in 1,000 non-smoking males aged 25 will die during the first year of coverage after underwriting.[2] Mortality approximately doubles for every extra ten years of age so that the mortality rate in the first year for underwritten non-smoking men is about 2.5 in 1,000 people at age 65.[3] Compare this with the US population male mortality rates of 1.3 per 1,000 at age 25 and 19.3 at age 65 (without regard to health or smoking status).
The mortality of underwritten persons rises much more quickly than the general population. At the end of 10 years the mortality of that 25 year-old, non-smoking male is 0.66/1000/year. Consequently, in a group of one thousand 25 year old males with a $100,000 policy, all of average health, a life insurance company would have to collect approximately $50 a year from each of a large group to cover the relatively few expected claims. (0.35 to 0.66 expected deaths in each year x $100,000 payout per death = $35 per policy). Administrative and sales commissions need to be accounted for in order for this to make business sense. A 10 year policy for a 25 year old non-smoking male person with preferred medical history may get offers as low as $90 per year for a $100,000 policy in the competitive US life insurance market.
