是lumpsum 还是monthly到死。选择比较好做了。
我的问题是:Calculate investment rate required for future value to be $0, starting value $700000 (presumed lumpsum), annual withdraw $48000 (presumed yearly benefit should go with monthly) with a 3% (inflation) increase each year, for 35 years (假设还要活35年)。 AI给出的最低投资回报必须是8.85%。
又问同样问题但没yearly Inflation increase,AI说 5.45%。
我问了四次第一个问题AI才给出答案,前三次都说计算出错了看来AI还需努力哈
