Would it be possible to "predict" what a persons pension total will be if historical data since February 2006 is available on a Excel spreadsheet? It is obvious that it will only be a prediction, and the actual amount will be influenced by a lot of factors. As a reference, I have attached the spreadsheet with the data since 2006. I have a colleague who needs to make a decision whether he can go of on 55, 60 or should he stay until 65. He currently is 50 years old.
