Life insurance exists to replace your income if you die and others depend on it. That's the entire purpose. Once you understand that clearly, most life insurance decisions become much simpler — and several expensive products become obviously wrong for most people.

Who Needs Life Insurance
You need life insurance if someone would suffer financially from your death. This typically means:
- A spouse or partner who depends on your income
- Children who depend on you for support
- Anyone who would be responsible for your debts (co-signed loans, jointly held mortgage)
You probably don't need life insurance if:
- You're single with no dependents
- Your spouse earns sufficient income independently
- You have enough assets that your family would be financially secure without your income
Children generally don't need life insurance (they have no income to replace). The pitch that you should "lock in their insurability" with a policy while they're young is a sales tactic, not a financial need.
Term Life Insurance: The Right Answer for Most People
Term life insurance provides a death benefit for a specific period (the "term") — typically 10, 20, or 30 years. If you die during the term, your beneficiaries receive the payout. If you don't, the policy expires and you paid for protection you fortunately didn't need.
What it costs: A healthy 35-year-old can buy a $500,000, 20-year term policy for approximately $25–40/month. A $1 million policy: $40–65/month. These numbers are genuinely inexpensive for the coverage provided.
Why it's right for most people: The need for life insurance typically peaks during the years when you have dependents and haven't yet accumulated significant wealth. A 30-year-old with young children, a mortgage, and limited savings has enormous financial exposure. A 55-year-old whose children are grown, mortgage is nearly paid, and retirement accounts are substantial has much less.
Term insurance matches coverage to the period of actual financial risk. By the time the 20-year term expires, most people have enough assets and reduced obligations that insurance is less critical.
Whole Life Insurance: What It Is and Who Needs It
Whole life insurance provides coverage for your entire life (as long as premiums are paid) and includes a "cash value" component that grows over time.
The premium comparison:
- Term: $500,000 coverage, 20-year term, 35-year-old = $35/month
- Whole life: $500,000 coverage, same person = $400–600/month
The difference — roughly $400–550/month — is the cost of the permanent coverage and the cash value component.
The cash value argument: Whole life insurance companies pitch the cash value as "forced savings" and a "tax-advantaged investment." Here's the reality: the internal rate of return on whole life cash value is typically 1–3% annually. After accounting for fees and the cost of the insurance component, it's a poor investment vehicle.
The "buy term, invest the difference" analysis: If you buy term at $35/month and invest the $450/month you save compared to whole life in a low-cost index fund earning 8%:
- After 20 years: approximately $264,000
- After 30 years: approximately $680,000
The whole life policy's cash value at 30 years on a $500,000 policy: typically $100,000–$200,000, depending on the specific policy.
When whole life makes sense:
- Estate planning for high-net-worth individuals needing lifelong coverage for tax reasons
- Funding the estate taxes on an illiquid estate
- Specific business succession planning scenarios
For the vast majority of people with normal financial situations, whole life insurance is an expensive product that poorly serves its stated purpose compared to term insurance combined with standard investment accounts.
How Much Coverage Do You Need?
Several frameworks exist for calculating coverage:
Income replacement method: 10–12 times your annual income. If you earn $70,000, you need $700,000–$840,000 in coverage. This gives your family approximately 10–12 years of income replacement invested conservatively.
DIME method:
- Debt: All outstanding debts (mortgage, car loans, credit cards, student loans)
- Income: Annual income × years until your youngest child is independent
- Mortgage: Remaining mortgage balance (if not already in debt)
- Education: Estimated college costs for each child
Add these together for your coverage amount. This tends to produce higher numbers than income multiples but accounts for specific obligations.
Practical starting point for a family: For a 30-something with a mortgage, young children, and one dependent spouse, $500,000–$1,000,000 in term coverage for 20 years covers most scenarios. Rates are low enough that erring on the side of more coverage costs only a few dollars per month.
Shopping for Term Life Insurance
Term life insurance is a commodity — the death benefit from one carrier is identical to another. Shop primarily on:
- Price — use comparison sites (Policygenius, SelectQuote) to see multiple carriers
- Financial strength rating — you want the insurer to be solvent in 20 years; look for A+ or A ratings from AM Best
- No-medical-exam vs. fully underwritten — fully underwritten policies are cheaper for healthy people; no-exam is faster but pricier
Buy term when you're young and healthy. Rates increase with age and health conditions. A 25-year-old pays roughly half what a 40-year-old pays for the same policy.
