Indexed universal life insurance is a type of permanent life insurance, which means it has a cash value component in addition to a death benefit. The money in your cash value account can earn interest based on a stock market index chosen by your insurer, such as the S&P 500 or the Nasdaq Composite. Funds don’t earn a fixed rate of interest but typically come with an interest rate guarantee. Indexed universal life (IUL) insurance policies can help you to build wealth while leaving behind a death benefit for your loved ones. These policies put a portion of the policyholder’s premium payments toward annual renewable term life insurance, with the remainder added to the cash value of the policy after fees are deducted.
