Week 50 Day 3: Life Insurance: Replacing Income Your Family Depends On

The two types that matter: (1) Term life insurance: covers a specific period (10, 20, or 30 years). Cheap. A healthy 35-year-old can get $500,000 of 20-year term coverage for $25-$35/month. When the term ends, coverage stops. This is what most people need -- coverage during the years when their family depends on their income. (2) Whole life / permanent insurance: covers your entire life, builds a cash value component, and costs 5-10 times more than term. For 95% of people, this is unnecessary and suboptimal. The mantra: buy term and invest the difference. The savings from choosing term over whole life ($200-$400/month) invested in VTI will build far more wealth than the cash value of a whole life policy.

How much life insurance do you need? The DIME method provides a simple framework: (1) Debt -- total outstanding debts (mortgage, car loans, student loans). (2) Income -- multiply your annual income by the number of years your family would need support (typically until the youngest child finishes college or your spouse reaches retirement age). (3) Mortgage -- enough to pay off the home (if not already included in Debt). (4) Education -- estimated cost of children's education. Example: $200,000 mortgage + $80,000 annual income x 15 years ($1,200,000) + $100,000 education = $1,500,000. A $1,500,000 20-year term policy for a healthy 35-year-old costs approximately $60-$80/month. When do you NOT need life insurance? (1) You are single with no dependents. (2) Your children are financially independent. (3) Your surviving spouse has sufficient income and assets to maintain their lifestyle. (4) You are retired with enough savings and Social Security to support your spouse. Many people keep paying for life insurance decades after they need it. If your mortgage is paid off, your kids are grown, and your retirement is funded, cancel the policy and redirect the premium to investments. The exception: estate planning for ultra-high-net-worth individuals who use permanent life insurance inside an irrevocable life insurance trust (ILIT) to fund estate taxes. This applies to estates above $13.61 million and requires specialized legal planning.

The debate between term and permanent life insurance has been one of the most contentious topics in personal finance for decades. The insurance industry generates significantly higher commissions on permanent (whole life, universal life) policies -- typically 50-110% of the first year's premium versus 30-50% for term policies -- creating a structural incentive for agents to recommend permanent insurance. Belth (1985, 2015) has documented this conflict of interest extensively, showing that the internal rate of return on whole life insurance cash values typically ranges from 2-4% after accounting for mortality charges, administrative fees, and surrender charges -- well below the long-term return of a diversified stock index (7-10% before inflation). The 'buy term and invest the difference' strategy was formalized by Primerica in the 1970s and has been validated by independent analyses by Consumer Reports (2023), which found that a 35-year-old who purchased $500,000 of 20-year term insurance ($35/month) and invested the premium difference vs. whole life ($385/month difference = $350/month invested at 7%) would accumulate approximately $171,000 after 20 years in the investment account, compared to approximately $80,000-$100,000 in whole life cash value. The term + invest strategy outperformed in 100% of scenarios tested by at least 50%. The limited cases where permanent insurance is appropriate involve illiquid estate planning (providing liquidity to pay estate taxes on illiquid assets like a family business or real estate), guaranteed insurability (for individuals with chronic health conditions who may lose access to term coverage upon renewal), or Supplemental Executive Retirement Plans (SERPs) that use corporate-owned life insurance as a tax-advantaged compensation vehicle. For the vast majority of households with term-insurable breadwinners, the academically and financially optimal strategy remains: buy the cheapest term policy that covers the coverage period, invest the premium savings in low-cost index funds, and allow the policy to expire when the family no longer depends on the insured's income.
