Our Methodology
We evaluated insurers on five factors: AM Best financial strength rating (minimum A), NAIC complaint index (lower = fewer complaints), sample premium competitiveness, policy conversion and rider options, and J.D. Power individual life insurance satisfaction scores. All sample rates shown are for a healthy 35-year-old non-smoker unless stated otherwise.

1. Northwestern Mutual — Best for Whole Life and Dividends
168+ years old. Largest US life insurer by total value of life insurance in force.
Northwestern Mutual has held an A++ (Superior) AM Best rating — the highest possible — for over 65 consecutive years. As a mutual company, it's owned by policyholders rather than shareholders, which allows it to return profits as annual dividends. Northwestern has paid dividends every year since 1872.
Their whole life policies build substantial cash value over time and are a cornerstone product for high-income earners, business owners, and estate planning. Their term life is competitively priced for healthy applicants. The main drawback: you must work through a Northwestern financial advisor, and the sales process can feel pushy.
Best for: High-income earners seeking permanent life insurance with dividend-paying whole life. Those building cash value for supplemental retirement income.
Pros
- A++ financial strength (168 years)
- Dividends paid every year since 1872
- Exceptional claims-paying history
- Strong whole life cash value growth
Cons
- Must buy through a financial advisor
- Higher premiums than online-direct
- No online quote tool
2. State Farm — Best for Overall Value and Customer Service
America's largest property-casualty insurer also offers highly-rated life insurance.
State Farm consistently ranks #1 in J.D. Power's Individual Life Insurance Study for overall customer satisfaction. Their local agent network is unmatched — over 19,000 agents nationwide — making them ideal for buyers who want a trusted local advisor rather than an online application.
Their term life rates are competitive for standard and preferred health classes, and their Instant Answer Term product provides up to $50,000 in coverage with no medical exam. State Farm's whole life policies include a guaranteed interest rate and paid-up additional insurance options.
Best for: Buyers who want a local agent relationship, bundling with auto or home insurance, and consistent claims service. The reliable choice for most Americans.
Pros
- #1 J.D. Power satisfaction
- 19,000+ local agents
- Bundle discounts with auto/home
- No-exam term up to $50k
Cons
- Not available in Massachusetts
- No direct online application for all products
- Rates slightly above cheapest competitors
3. Protective Life — Best for Lowest Term Life Rates
Consistently among the cheapest term life rates in the US for healthy applicants.
If your primary goal is maximum death benefit for minimum premium, Protective Life is one of the most consistent low-price options for healthy applicants. Their Classic Choice Term regularly quotes 10–20% below industry average for preferred-plus health classes.
Protective offers term lengths from 10 to 40 years — the longest available — making them ideal for younger buyers who want to lock in low rates for extended periods. They also offer policy conversion to permanent insurance without a new health exam.
Best for: Healthy buyers aged 25–45 who want the cheapest possible term life premium and don't need a local agent relationship.
Pros
- Among lowest term rates nationally
- 40-year term available
- Conversion option without new exam
- Strong financial ratings
Cons
- Rates less competitive for tobacco users
- No agent network (broker-only)
- Online experience is basic
4. MassMutual — Best for Whole Life and Estate Planning
173-year-old mutual company. Strong dividend history and estate planning tools.
MassMutual (Massachusetts Mutual Life Insurance Company) has distributed dividends to eligible whole life policyholders every year since 1869. Their whole life products are premier choices for permanent insurance strategies including Infinite Banking Concept (IBC), key person insurance, and wealth transfer to heirs.
They also offer a strong Haven Term product (their direct-to-consumer term arm) starting at competitive rates with a fully digital application. Disability income insurance is another area where MassMutual excels, with robust own-occupation riders.
Best for: Business owners, high-net-worth individuals building permanent insurance for estate planning, and professionals needing disability income coverage alongside life insurance.
Pros
- A++ rating, 173-year history
- Dividends paid since 1869
- Haven Term for digital buyers

Cons
- Whole life requires agent
- Premium whole life isn't cheap
- Complex product lineup
5. Banner Life (Legal & General America) — Best Cheap Term Rates for All Health Classes
Subsidiary of Legal & General, one of the world's largest insurers. Very competitive term rates.
Banner Life (which operates as William Penn in New York) is part of Legal & General America, subsidiary of one of the world's largest insurers. They offer some of the most competitive term rates for tobacco users and substandard health classes, making them a go-to for brokers shopping coverage for clients who've been declined elsewhere.
Banner accepts coverage amounts as high as $10 million with competitive pricing, and their underwriting turnaround is typically faster than large mutual companies. Term lengths available from 10 to 40 years.
Best for: Budget-conscious term buyers, tobacco users, and applicants with common health conditions who want competitive rates without being declined outright.
Pros
- Excellent rates for tobacco users
- Competitive for standard health classes
- Fast underwriting
- Backed by massive global parent

Not sure how much coverage you need? Run our calculator before getting quotes.
Calculate How Much Life Insurance You Need →How Much Life Insurance Do You Actually Need?
The most common rule of thumb is 10–12x your annual income. But a more precise method is the DIME formula:
- D — Debt: All outstanding debts (mortgage, car loans, credit cards, student loans)
- I — Income: Annual income × number of years until your youngest child turns 18
- M — Mortgage: Remaining mortgage balance
- E — Education: Estimated college costs for each child
Add these four numbers together to get your minimum coverage need. For a 35-year-old earning $80,000/year with a $350,000 mortgage, two kids, and $30,000 in other debt, the DIME formula suggests approximately $1.7 million in coverage. A 20-year $500,000 term policy from Protective or Banner would run around $18–22/month as a starting point.
Term vs. Whole Life: Which Should You Buy?
| Factor | Term Life | Whole Life |
|---|---|---|
| Coverage period | 10–40 years | Lifetime (permanent) |
| Monthly premium ($500k, 35M) | $17–$28/mo | $300–$600/mo |
| Cash value | None | Builds over time |
| Best for | Income replacement, mortgage payoff | Estate planning, wealth transfer |
| Flexibility | Simple; expires at term end | Convertible, can borrow against |
| Verdict | Most people should start here | Consider after maxing retirement accounts |
Most financial planners recommend starting with term life and only considering whole life after you've maxed out your 401(k), Roth IRA, and other tax-advantaged retirement accounts. The premium difference — $250+/month — invested in low-cost index funds typically outperforms whole life cash value over a 20-year period.
