The short answer
For most people, life insurance is best treated as protection, not an investment. The phrase buy term and invest the rest captures the common-sense case: cheap term insurance covers your family, and the money you save versus permanent insurance goes into ordinary investments that usually grow faster and cost less. Permanent life insurance can have a place, but for the average family seeking growth, it rarely beats a low-cost investment account after fees.
So the honest answer is that life insurance is usually a good protection tool and a mediocre investment — and it is worth being clear about which job you are asking it to do.
When buy term and invest the rest wins
For a typical family that needs coverage for a set number of years — while raising kids or paying a mortgage — term insurance is far cheaper, and investing the premium difference in retirement accounts usually produces more wealth than a permanent policy's cash value, which is weighed down by insurance costs and fees. Our guide to indexed universal life shows how those fees erode returns in one popular permanent product.
The math favors term for most families because the cost gap, invested over decades, compounds.
When permanent insurance has a place
Permanent life insurance can make sense for specific goals: a lifelong need for coverage, estate liquidity, funding a special needs trust, or someone who has maxed out other tax-advantaged accounts and values the tax treatment. The key is buying it for the coverage and planning benefits, not as a primary investment. If it was sold to you mainly as a savings vehicle, get an unbiased second opinion. Our life insurance overview covers the honest use cases.
The takeaway: use life insurance to protect and plan; for pure investment growth, low-cost investments usually win — buy permanent coverage for its coverage, not its returns.
