These life insurance policies allow their owners to make contributions, part of which goes to paying the cost of the insurance protection, and the balance can be invested in different investments.

There are drawbacks. The cost of the insurance protection rises over time, leaving less of the balance from payments you make to be invested. These financial products are also very complicated and may not generate the returns their owners expect. There are special cases where these insurance products make sense, usually for high net worth investors.

For most people, it's best to keep things simple. Buy a term life insurance policy to cover the need for financial protection in the case of death.

Term life policies are affordable. If there's money left to be invested, do that in a separate account with an online brokerage firm. You'll pay lower fees and enjoy fewer complications.
