How Much Life Insurance Do You Need?

Life insurance exists for one reason: if someone depends on your income, it replaces that income if you're gone. The hard questions are how much you need and what kind to buy. Here's a straightforward way to think about both.

Who actually needs it

If no one relies on you financially, you may not need life insurance at all. You most likely do if you have a spouse or partner who shares expenses, children, aging parents you support, or shared debt like a mortgage. The goal is protecting the people who depend on you, not insuring yourself for its own sake.

The DIME method

A common way to estimate coverage adds up four things:

• D — Debt: all debts except the mortgage (cards, car, student loans).
• I — Income: your annual income times the years your family would need it replaced.
• M — Mortgage: the remaining balance, so they can keep the home.
• E — Education: expected costs of your children's schooling.

Add those, subtract savings and any coverage you already have, and you have a working number. The life insurance needs calculator does this for you. Industry educators like the Insurance Information Institute outline the same approach.

Term vs whole life

For most families, term life is the right answer. It covers a set period (say 20 or 30 years) for a low premium — a healthy adult can often insure a large policy for the cost of a couple of streaming subscriptions. The idea is to be covered during the years others depend on you; by the time the term ends, the mortgage is smaller and the kids are grown.

Whole (permanent) life costs far more and bundles an investment component. It suits specific estate-planning situations, but for ordinary income protection, term gives you far more coverage per dollar. The National Association of Insurance Commissioners publishes a free, unbiased Life Insurance Buyer's Guide worth reading before you shop.

Practical tips

• Buy when you're young and healthy — premiums are largely set by age and health.
• Match the term to your need — long enough to cover the dependent years.
• Compare quotes — prices for the same coverage vary by insurer.
