Fixed Deposit vs Bond: After-Tax Return Comparison
Both fixed deposits (CDs) and bonds generate interest income subject to federal income tax. CDs compound interest, while bonds pay periodic coupon interest (simple interest per period). Over longer holding periods, compounding gives CDs an edge at the same rate.
Bonds may offer additional upside through price appreciation if interest rates fall, and Treasury bonds are exempt from state/local taxes. CDs are FDIC-insured up to $250,000, making them lower risk than corporate bonds.
