The interest rates and terms for Liberty Bonds were determined by the U.S. Treasury Department based on market conditions and the government's financial needs. Interest rates for Liberty Bonds varied between 3.5% and 4.75% depending on the series, and the maturities of the bonds ranged from 5 to 30 years. Investors received interest payments semi-annually, and the bonds could be redeemed at maturity or, in some cases, earlier at the bondholder's request.
