Two kinds of coverage protect your income for the people who depend on it — one if you die, one if you can't work. Most people over-focus on the first and skip the second, which is backwards from a pure numbers standpoint.
Life Insurance: Term vs. Whole
Life insurance replaces your income for dependents if you die. There are two very different products sold under that name:
Term Life
- Covers a fixed period (10, 20, 30 years)
- Pure insurance — no cash value
- Costs a fraction of whole life for the same death benefit
- Coverage ends if you outlive the term
Whole Life
- Covers your entire life
- Builds cash value you can borrow against
- Costs 5–15x more than term for the same death benefit
- Complex fee structure that can be hard to evaluate
For most people with dependents, term life covers the actual need — replacing income during working years — for a much lower cost, freeing up money to invest separately (see Lesson 2 for the "buy term, invest the difference" math). Whole life can make sense for specific estate-planning needs or people who want the forced savings discipline, but it's frequently oversold as a general-purpose solution when term plus investing would serve most families better.
How Much Coverage Do You Actually Need?
A common starting estimate: 10× your annual income, adjusted for your specific situation — outstanding debts (mortgage, loans), years until kids are financially independent, and any existing savings that could offset the need.
Disability Insurance: The Coverage Most People Skip
Here's the uncomfortable statistic: over a full career, the odds of a disabling injury or illness that keeps you out of work for an extended period are meaningfully higher than the odds of dying during your working years — yet most people insure the smaller risk and skip the bigger one.
Disability insurance replaces a portion of your income (typically 50–60%) if illness or injury prevents you from working. Many employers offer basic short-term and long-term disability coverage — check what you already have before assuming you need to buy more, and pay attention to how the policy defines "disabled," since some only pay out if you can't work any job, not just your own.
How to Buy Term Life Insurance
Buying term life insurance is a short process once you know your number — here's how to get there.
- Calculate the coverage you need. A common rule of thumb is 10–12 times your annual income.
- Choose a term length matching your longest obligation. Until the mortgage is paid off, or until the kids are financially independent.
- Get quotes from an independent broker. They can compare multiple insurers at once instead of just one company's rates.
- Complete the medical exam promptly. Delays here are the single most common reason applications stall for weeks.
- Name a specific beneficiary, not just “my estate”. And update it after every major life event — marriage, divorce, a new child.
Key Takeaways
- Term life insurance covers the actual need — income replacement — at a fraction of whole life's cost.
- A common starting point is 10× annual income, adjusted for debts and dependents' needs.
- Disability is statistically more likely than death during working years, yet far less commonly insured.
- Check your employer-provided disability coverage before assuming you need to buy your own.
