Life Insurance 101

Most people who have life insurance don't know what kind they have, how much they have, or whether the amount is anywhere near what their family would actually need.

They signed up for whatever their employer offered during open enrollment — usually one to two times their annual salary — and haven't thought about it since. That coverage, for most families with a mortgage and children, is a fraction of what would actually be needed. The gap between what people think they have and what would cover their family's expenses for a meaningful period is almost always significant.

Life insurance is not complicated. The industry makes it seem complicated because complicated products generate higher margins. The actual decision most people need to make is simple: how much income would need to be replaced, for how long, and what's the cheapest way to provide that.

Who actually needs life insurance

Life insurance exists to replace income that would be lost if you die. If no one depends on your income — no spouse, no children, no one who would face financial hardship without your paycheck — you probably don't need it. A single person with no dependents and no one co-signed on their debt is not a candidate for life insurance. The premium is a cost with no real benefit in that situation.

The picture changes immediately if someone relies on your income. A spouse who earns less or not at all, children who need support for years, a family with a mortgage that requires two incomes to sustain — these are the situations life insurance is designed for. The question shifts from 'do I need it' to 'how much and what kind.'

Term vs. permanent — why term is almost always the right choice

Term life insurance covers you for a specific period — typically 10, 20, or 30 years. If you die during the term, your beneficiaries receive the death benefit. If you outlive the term, the policy expires. It's simple, transparent, and cheap relative to the coverage provided.

Whole life and other permanent policies cover you for your entire life and include a cash value component that builds over time. They cost five to fifteen times more per dollar of coverage than term insurance. The pitch is that you're building an asset while also getting coverage. The reality is that the investment component almost always performs worse than what you'd earn investing the premium difference in a low-cost index fund — and the fees inside permanent policies are rarely disclosed clearly.

The common financial planning guidance for the last several decades has been to buy term and invest the difference — get the coverage you need at the lowest possible cost, and put the money you'd have spent on a permanent policy premium into your own investment accounts. The math on this consistently favors term by a large margin for most people.

Permanent insurance makes sense in a narrow set of situations: estate planning for high-net-worth individuals, specific business arrangements, or in rare cases where someone is uninsurable and needs lifelong coverage. For most people in their 30s and 40s trying to protect their families, term is the answer.

How much coverage you actually need

The standard starting point is 10 to 12 times your annual income. On a $70,000 salary, that's $700,000 to $840,000 in coverage. The idea is that the death benefit, invested conservatively, would generate enough annual income to replace your earnings for a long period without drawing down the principal rapidly.

Adjust the number for your specific situation. Add your mortgage balance, because the surviving spouse needs to cover housing. Add several years of childcare or dependent care costs if applicable. If your spouse doesn't work, add more — the income gap is total rather than partial. If you carry significant debt, add that too. The 10 to 12x formula is a useful starting point, not a ceiling.

Term coverage in these amounts is cheaper than most people expect. A healthy 35-year-old can typically get a 20-year $1 million term policy for $40 to $60 a month. That coverage protects the family through the years the mortgage is largest, the children are young, and the financial exposure is highest — at a cost less than most streaming subscriptions combined.

Group life through your employer — the gap most people don't know about

Employer-provided group life insurance is typically one to two times your annual salary. On a $70,000 salary, that's $70,000 to $140,000. For a family with a mortgage, children, and a surviving spouse who earns less or not at all, $140,000 covers maybe two to three years of expenses. It's not nothing. It's also not enough.

Group coverage is also not portable. When you leave the job, the coverage ends. If you leave at 45 after a health diagnosis that makes you a rated risk for individual coverage, you're trying to buy life insurance when it's most expensive — or when it's unavailable. People who rely entirely on group coverage and then change jobs or get laid off discover this problem at the worst possible moment.

The group coverage is a benefit worth taking — it's usually free or low-cost. It's not a reason to forgo individual term coverage. The two serve different purposes: group coverage is a baseline provided by your employer, individual term is the actual protection plan.

When to buy — the window most people miss

Life insurance premiums are set based on your age and health at the time of application. Young and healthy means cheap. The same coverage that costs $45 a month at 32 costs $90 to $120 at 45, and meaningfully more if any health conditions have developed in the intervening years.

The right time to buy is when you first have dependents — when you get married, when a child arrives, when you take on a mortgage that requires your income. That's usually when the need is clearest and the cost is still relatively low. Waiting until you feel more settled financially means waiting until the premiums are higher and the window of easy insurability is narrower.

Some health conditions don't affect insurability at all. Others raise the premium meaningfully. A few make coverage difficult to obtain. You won't know which category you're in until you apply. Applying at 32 when you're healthy gives you the best possible outcome. Applying at 48 after a health event gives you whatever outcome the underwriters decide.

The coverage gap life insurance doesn't fill

Life insurance covers income loss from death. It doesn't cover income loss from disability — from being alive and unable to work for months or years due to illness or injury. Statistically, a working-age adult is more likely to experience a long-term disability than to die during their prime working years.

Disability insurance replaces a portion of your income if you can't work due to a covered condition. Many employers offer short-term and long-term disability coverage, and private policies are available for those without it. People who think carefully about their financial protection almost always have both. People who only think about life insurance are covering the less likely risk while leaving the more likely one unaddressed.

The years your family depends on your income are exactly the years term life insurance costs least. That window doesn't stay open forever.
