Your life insurance premium is not a mystery number. Underwriters build it from a short list of factors, and knowing the list tells you which levers you can actually pull to pay less.
1. Age
Age is the biggest factor. A $500,000 20-year term policy for a healthy non-smoking man costs about $21 a month at 30, $36 at 40, $85 at 50, and $215 at 60 in preferred health (Mozdex 2026). Women pay a bit less at every age: $18, $30, $68, and $175. You cannot change your age, but you can stop waiting. Every birthday raises the price of every policy you will ever be quoted.
2. Health class
After the exam, the insurer sorts you into a rate class: preferred plus, preferred, standard plus, standard, or a table-rated substandard class. The jump from preferred to standard adds roughly 25 to 35 percent to the premium. Our health class cost breakdown shows the dollar difference at each step, and our medical exam guide covers how to prepare.
3. Tobacco use
Smokers pay roughly two to three times what non-smokers pay. A 55-year-old man might pay $212 a month as a non-smoker versus $549 as a smoker for the same $500,000 policy. Most insurers require 12 months nicotine-free, verified by a urine test, before they reclassify you. Vaping counts as tobacco use at most carriers.
4. Coverage amount and term length
Premiums scale close to linearly with the face amount: twice the coverage costs roughly twice the premium, with a small per-policy discount at higher face amounts. Term length adds cost too. A 30-year term runs about $10 to $35 more a month than a 20-year term at the same face amount. Buy the term that matches the need. Paying for 30 years of coverage when the mortgage ends in 15 wastes money.
5. Gender
Women pay less because they live longer on average. The gap runs 10 to 20 percent at most ages. You cannot change this, and in a few states unisex pricing rules narrow it, but it is part of every quote.
6. Occupation and hobbies
Desk jobs price at standard rates. Hazardous occupations like roofing, commercial fishing, or piloting add surcharges. The same goes for hobbies: private aviation, scuba diving beyond recreational limits, and motorsports all raise premiums. Some carriers are more lenient than others on specific hobbies, which is another reason to compare quotes.
7. The carrier itself
Identical applicants get quotes that differ 30 to 50 percent between carriers. MoneyGeek’s 2026 survey found the cheapest term carriers, Transamerica and Banner Life, within a dollar a month of each other for a 40-year-old woman, while other well-known names priced $5 to $10 higher for the same profile. The carrier you pick is a factor you control completely. Our quote comparison guide shows how to shop without getting steered.
What you can actually change
Three of the seven are in your hands: buy young, quit nicotine a year before applying, and shop multiple carriers. Health class is partly in your hands through blood pressure, weight, and cholesterol. The rest you accept and price around. Nobody should pay a lazy premium. The market is competitive enough that 30 minutes of comparison shopping usually saves hundreds a year.
