嗨，爱思考的PZer你好：
这个题目的目标是在本书的122页
The simplest way to bring this concept to life is to work with a basic case study. Imagine a family, the Smiths, with financial assets of US$25 million. (For the sake of simplicity, we are assuming that they do not pay taxes and that all assets are owned in a single structure.) The parents are in their mid-fifties, and the household spends about US$500,000 a year. They expect that inflation will average about 2% per year for the foreseeable future. They express four important goals and are concerned that they may not be able to meet all of them:
1 They need a 95% chance of being able to maintain their current expenditures over the next five years.
和分析
Module A and that the appropriately adjusted expected return for that module is 2.3%. Discounting a US$500,000 annual cash flow, inflated by 2% a year from Year 2 onwards。
也就是5年现金流是500,000, 回报为2.3%, inflation 是2%求现值，第二年才有Inflation。
PMT = 500,000， N= 5 I = 1.023/1.02-1
算出来是2478092，因为第二年才inflation 所以得出的数字需要除以1.02 也就是2429502。投资我们取千位也就是2430000。
