Methods and systems are disclosed for calculating borrowing cost of municipal debt instruments. In an embodiment, a method receives terms, yield curve and interest rate volatility data for a set of bonds and then specifies an evolution of interest rates for each of the bonds. The method receives an option value V for each of the bonds and determines proceeds P for each bond. The method obtains an Option-Adjusted True Interest Cost (OATIC) for the bonds by adding the option values V to the proceeds P and finding a single discount rate that equates a present value of respective debt service for the bonds to P+V. In another embodiment, a system specifies an evolution of interest rates and receives an option value V for municipal debt offerings. The system selects a bond based on expected costs of bonds, which are calculated using OATIC values and identifies a preferred bond.
