Nominal and Effective Interest Rates

In all our examples in the previous section, we implicitly assumed that payments are received once a year, or annually. However, some of the most familiar financial transactions in both personal financial matters and engineering economic analysis involve nonannual payments; for example, monthly mortgage payments and daily earnings on savings accounts. Thus, if we are to compare different cash flows with different compounding periods, we need to address them on a common basis. The need to do this has led to the development of the concepts of nominal interest rate and effective interest rate.
