在进行固定资产长期投资决策中,要计算现金流量表,其中计算该表中各年度的现金净流量(NCF)的现值,如果用具有相应计算程序的电子计算机来处理,当然是很容易的事,但如果没有相应的电子计算机,或决策人员在外又要及时评价对比新方案时,就只有通过查“一元的现值”表,找出各年度的贴现率后,再乘以各年的现金净流量而求得。这种方法工作量大,效率低,容易出差错,精确度不高。在实践中,我们根据管理人员常用的电子计算器的运算功能,总结出一种用常用电子计算器计算各年现金净流量现值的方法,极大地提高了工作速度。现以“CA-SIO fx-8100型计算器”为例(凡具有存贮、乘方运算功能的计算器均可),介绍如下:
In making long-term investment decisions on fixed assets, it is necessary to calculate a cash flow statement, in which the current value of the net cash flow (NCF) for each year in the table is calculated. If it is processed by an electronic computer with a corresponding calculation program, it is of course easy. However, if there is no corresponding computer, or if the decision-makers are to evaluate and compare new plans in a timely manner, they can only find out the discount rate for each year by multiplying the discount value of each year by multiplying the annual value of each year. Cash flow is calculated. This method is labor-intensive, inefficient, error-prone, and inaccurate. In practice, based on the calculation functions of electronic calculators commonly used by management personnel, we have summarized a method for calculating the present value of net cash flow for each year using commonly used electronic calculators, which has greatly improved the working speed. Now take “CA-SIO fx-8100 type calculator” as an example (any calculator with storage and power calculation function can be used), introduced as follows:
