Adjusting the ate of etun The fequency of compounding: Quoted (stated ate Effective ate Always use the effective annual ate to discount annual CFs, effective monthly ate to discount monthly CFs etc. The case of inflation: Nominal ate Real ate Always use the nominal ate to discount nominal CFs and the eal ate to discount eal CFs. 1 14 Effective to Effective: Example The annual inteest ate is 8%.
