是lumpsum 還是monthly到死。選擇比較好做了。
我的問題是: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 (假設還要活35年)。 AI給出的最低投資回報必須是8.85%。
又問同樣問題但沒yearly Inflation increase,AI說 5.45%。
我問了四次第一個問題AI才給出答案,前三次都說計算出錯了看來AI還需努力哈
