I understand the pros and cons of all these fixed investment products. However, does someone know of a calculator that lets one compare rates from all three at the same time in order to determine which rate is best. The calculator would need to incorporate the inherent benefits of each of these products. For instance, it would have to factor in compound interest for a bank CD, but not for a brokered CD (whose interest would earn a different rate), and no state tax for U.S. Treasuries, etc.. I should end up showing you what the net-net yield of each product would be at the end of the term so one could see which product would actually earn the most.
