A healthy 40-year-old man can buy $500,000 of 20-year term life insurance for $48 a month with no medical exam. That is a real live quote for SBLI. Other companies charge $65 to $80 a month for the same policy, which means picking the wrong insurer costs $204 to $384 a year for identical coverage.
This guide ranks the 16 best life insurance companies on the four things that actually matter: prices you can verify, financial strength, complaint history, and customer satisfaction. It also covers the two topics most lists skip: how claims really get paid, and which insurer to call when you have a health condition.

What life insurance actually costs
Term life is cheap. A healthy 30-year-old pays about $25/mo for $500K 20-year term. Whole life costs 5-7x more for the same death benefit. Most young adults overestimate term costs by 10-12x — that misjudgment keeps millions uninsured.
Claims: will your family actually get paid?
No reviewer publishes denial rates, but complaint records are a proxy. Northwestern Mutual (0.08 index) and Guardian (low complaints) barely generate claim disputes. Companies that fight claims generate complaints — these two do not.
Life insurance with health conditions
Prudential is the most lenient for diabetes and high blood pressure. Banner Life is strictest (best rates go to the healthiest). Apply to the right carrier first to avoid wasted weeks.
How to actually buy life insurance
- Decide term vs permanent. 9 in 10 buyers should choose term.
- Calculate coverage: 10-12x annual income plus debts.
- Get 3 quotes. Same buyer, same policy, different prices.
- Apply honestly. Lying on the application voids the policy.
Red flags: when to walk away
- Agent pushes whole life when you asked for term
- “Guaranteed approval” with no health questions (overpriced)
- Pressure to decide today
- Cannot explain fees in plain English
