    2. 年值法

    將一方案所預期的現金流量,按其折現率(或最低可接受報酬率),轉變成等值的年值當量(Equivalent Uniform Annul Worth)以進行方案的評估,習慣上以AW(Annual Worth)來代表此一當量值,年值的計算方式如下式,實際上只是將計算出來的淨現值,乘上資金回收因子(將現值轉為年值)即可。

    公式在這個網站上

    AW:年值

    A:以初期為基準點的年值

    P:現值

    N:計畫預期使用壽年

    i:折現率

    此方法的決策準則為獨立方案評估時,在已知折現率、計畫預期使用壽年後,計算出AW,值若大於零,則該方案值得投資,而若是對於兩個以上互斥的方案評估時,則選擇年值較大的方案。

    Annual Worth(年値法)

    Many of the expenses a company must meet -- rent, wages, taxes -- occur on a regular periodic basis. It is therefore attractive to present investment options in terms of their equivalent uniform annual cost. The calculations for this approach are simple -- we convert present worth to equivalent annual worth by multiplying by the appropriate conversion factor -- but some care is needed in deciding what period of time to consider.

    For example, suppose we have a machine that we purchase for a given cost P, and which we expect to sell after N years for a salvage cost S. What is the equivalent annual cost of the machine? (This number is useful if we want to compare buying the machine outright with renting it for a period.) The equivalent cost is conventionally referred to as capital recovery, and can be calculated from

    CR=P(A/P,i,N) - S(A/F,i,N)

    where the first term on the right-hand side is known as the capital recovery
