How do I choose a life insurance policy?

For most people with dependents and a finite income-replacement need, term life is the right starting point — it's the most coverage per premium dollar. Add permanent coverage only if you have a specific estate or lifelong need.

The life insurance market offers a spectrum of products — term life, whole life, universal life, variable life — each with different premium structures, cash value features, and use cases. For most people, the decision is simpler than the industry makes it seem: match the product to the need. The III's guide to life insurance types is the clearest overview of how each product is structured.

Step 1 — Define what you're insuring against

Income replacement while dependents are young: term life is designed for this.
Permanent death benefit (estate planning, business succession, lifelong dependent): permanent life insurance addresses this.
Cash value accumulation: whole or universal life can serve this — but compare the internal rate of return to other savings vehicles before buying.
Mortgage payoff protection: decreasing term or standard term tied to the mortgage term.

Step 2 — Choose between term and permanent

Term life is pure insurance: you pay premiums for a fixed period (10, 20, or 30 years), and if you die during that period, the benefit pays. If you outlive the term, coverage ends with no residual value. It is the most cost-effective option per dollar of coverage. Permanent life insurance (whole, universal, variable) combines a death benefit with a savings or investment component — premiums are 5–15x higher for the same face amount. It's appropriate when you need coverage that doesn't expire.

Step 3 — Size the coverage amount

Start at 10–12x your annual gross income as a rough floor. Adjust up for: young children, high debt (mortgage + student loans + business), low existing savings, non-working spouse. Adjust down for: no dependents, substantial existing assets, children who are nearly independent. A more precise method: add up all debt obligations, multiply income by the number of years until your youngest child is independent, and add education costs — that's the DIME method.

Step 4 — Choose the term length

Match the term to the income-replacement window. A 35-year-old with a 30-year mortgage and a newborn child needs at least a 25–30-year term. A 50-year-old with college-age kids and a 10-year mortgage needs 10–15 years. Buying longer coverage than you need wastes premium; buying shorter creates a gap.

Step 5 — Evaluate the insurer's financial strength

Life insurance is a long-duration contract — you need the insurer to be solvent in 20–30 years. Check financial strength ratings from AM Best, Moody's, or S&P. Look for A or better from AM Best. State guaranty associations provide a backstop (up to $300,000 in most states) if an insurer becomes insolvent, but that's a last resort.
