Indexed retirement insurance contracts credit interest to your money by tracking the gains of a market index, like the S&P 500, but without the risk of losing any of your money whenever the market index is down. However, the interest rate credited to your money is not the actual gains in the market index, because your money is not actually invested in shares of the index, nor in the stock of any companies that make up the index. Which means that the interest rate credited to your money is only tracking the gains in the market index.
