<prompt> Human: I just signed up for a Personal Capital account after spending the day handling personal investments, investing my wifes 401k roll-over, rebalancing my 401k, etc. I needed a better grasp of the 3 retirement accounts we have, investment account, bank accounts, etc.When I went to the recommendations section, it said Invest Your X of Idle Cash to Grow Your Portfolio. Now, some of that should legitimately be invested, such as small cash balances in my investments accounts, excess cash in checking, etc. But a chunk of that was cash sitting in savings -- my emergency fund. To be honest, Ive thought about doing the same thing. We make a decent amount of money 200Kyr. We are middle-aged and, barring any setbacks, should be well-off in retirement. I have access enough credit via credit cards to handle any emergency the savings would cover. Does it really make sense for a person in my situation to have cash just sitting there, losing value over time, rather than invested in at least a TIPS fund?Ive been an avid lurker here on rPersonalFinance for a while and didnt really find anything that speaks to this sort of thing in the prime directive, wiki or in the post history.So, fellow redditors, at what point in a persons financial life -- if ever -- is a personal savings account redundant?  <response>: We are middle-aged and, barring any setbacks, should be well-off in retirementProbably no need to take risk with every penny to your name, then. Id keep a healthy emergency fund.
