What actually determines your life insurance rate
The factors insurers price, ranked by how much they move your premium — and which ones you can still change.
What determines the price of life insurance?
Age and health drive most of it, followed by tobacco use, the amount of coverage, and the length of the term. Insurers also weigh your height and weight, prescription history, driving record, family medical history, and risky hobbies or occupations. Sex matters too, since women statistically live longer.
Two people the same age can be quoted premiums that differ by 400%. Underwriting isn't arbitrary — every factor maps to mortality data. Here's what moves the number, roughly in order of impact.
1. Age — the largest single factor
Mortality risk compounds with age, and so does price. Rates typically rise 8–10% per year of age in your thirties and forties, and accelerate sharply after 50. The difference between buying at 35 and buying at 45 on the same policy is often 60–80%.
Many insurers also price by insurance age, which rounds to your nearest birthday — meaning you can jump a full age band months before your actual birthday. If you're within six months of a birthday, applying now can genuinely save money.
2. Tobacco and nicotine use
The single biggest controllable factor. Smokers commonly pay two to three times what non-smokers pay for identical coverage. Most carriers require 12 months nicotine-free for non-smoker rates, and some want 24–60 months for their best classes.
Note that this usually includes vaping, cigars, chewing tobacco, and nicotine patches or gum. Carriers vary considerably on occasional cigar use — it's one of the areas where shopping between carriers pays off most.
3. Health conditions and medications
Diabetes, heart disease, cancer history, high blood pressure, sleep apnea, and mental health treatment all factor in. What matters isn't just the diagnosis but the control: well-managed diabetes with a good A1C is priced very differently from uncontrolled diabetes.
Insurers see your prescription history through pharmacy databases, so medications reveal conditions whether or not you mention them.
4. Height and weight (build)
Every carrier publishes a build chart. Falling outside it moves you down a rate class or into table ratings. Build charts differ meaningfully between carriers — the same person can be Preferred at one and Standard at another purely on this factor.
5. Family history
Death of a parent or sibling from heart disease or certain cancers before age 60 (sometimes 65) can disqualify you from top-tier classes even if you're in perfect health. It's one of the few factors nobody can change.
6. Driving record
Insurers pull your motor vehicle report. A DUI within three to five years is a serious problem; multiple moving violations signal risk-taking. This surprises people who assume driving affects only auto insurance.
7. Occupation and hobbies
Commercial fishing, roofing, logging, and aviation carry occupational ratings. So do scuba diving beyond recreational depths, private aviation, rock climbing, and motorsport. These usually produce a flat extra charge per thousand of coverage rather than a worse overall class.
8. The policy design itself
Coverage amount, term length, and product type all move the price. Interestingly, price per thousand often drops at breakpoints like $250,000, $500,000, and $1,000,000 — so $500,000 can occasionally cost less in total than $450,000. Always ask your agent to quote just above the next breakpoint.
What doesn't affect your rate
Your credit score doesn't directly set life insurance pricing the way it does auto or home. Gender does — women generally pay less due to longer life expectancy. And an existing policy elsewhere doesn't raise your rate, though total coverage across all carriers is reviewed for financial justification.
