Life insurance is one of those topics where the industry makes things way more complicated than they need to be — largely because more complex products mean higher commissions for agents. Here's the straightforward truth: most people need simple, affordable term life insurance. Almost nobody needs whole life.
Term Life vs. Whole Life: The Only Comparison You Need
| Feature | Term Life | Whole Life |
|---|---|---|
| Coverage period | 10, 20, or 30 years | Entire lifetime |
| Monthly cost (35-year-old, $500K) | $25–$45 | $350–$500 |
| Cash value | No | Yes (grows slowly) |
| Complexity | Simple | Complex |
| Best for | 95% of people | Very specific estate planning situations |
| Recommended by most fee-only advisors | Yes | Rarely |
The math is clear: A 35-year-old can get $500,000 of term coverage for $30/month. The same whole life policy costs $400+/month. The $370/month difference invested in an index fund at 7% for 30 years grows to over $440,000. You end up with more money AND more coverage with "buy term and invest the difference."
How Much Life Insurance Do You Need?
The standard method is the DIME formula:
- D — Debt: All outstanding debts (mortgage, car loans, student loans, credit cards)
- I — Income: 10–12× your annual income to replace earnings
- M — Mortgage: Remaining mortgage balance (if not included in Debt)
- E — Education: Estimated college costs for each child ($100,000–$250,000 per child)
Example: 35-year-old with family
- Debts: $30,000 (car + student loans)
- Income replacement: $80,000 × 10 = $800,000
- Mortgage: $280,000
- Education (2 kids): $300,000
- Total coverage needed: ~$1,400,000
Round up to $1,500,000. A 30-year term policy at this amount costs approximately $60–$90/month for a healthy 35-year-old.
Who Needs Life Insurance (And Who Doesn't)
You NEED life insurance if:
- You have a spouse or partner who depends on your income
- You have children
- You have a mortgage or significant debt someone else would be responsible for
- You're a stay-at-home parent (your services would cost $30,000–$50,000/year to replace)
- You co-signed loans with someone
You probably DON'T need life insurance if:
- You're single with no dependents
- You have no debt (or only debt in your name)
- You're retired with sufficient savings
- Your children are financially independent adults
- You have enough assets to cover final expenses and leave your desired legacy
The Best Time to Buy
Life insurance premiums are based on age and health. Buy when you're young and healthy — a policy purchased at 30 costs 30–50% less than the same policy at 40. And if you develop health conditions, you may not qualify at all later.
