    Engineering Economy ,y de4ning its languageandnotations.

    Engineering Economy 'actors apply compound interest

    to calculate e0uivalent cash 3o) values. The ta,ulatedvalues at the end of the ,oo7 or you can use thefunctions in spreadsheets2 convert from one cash 3o)0uantity P- '- *- or 2 to another.

    *ssumptions:1. Fnterest is compounded once per period". Cash 3o) occurs at the end of the period&. Time # is period # or the start of period 1$. *ll periods are the same length

    a single dis,ursement or receipt a set of e0ual amounts in(out over a se0uence of periods !

    annuity a set of e0ual amounts in(out that change ,y a constant
