As a general rule, how much in “liquid” emergency savings should I have?
I recently started my first job and now have more money than I've ever had in my life (woohoo!) However I am curious how much I should keep in checking or savings accounts (i.e. things which can easily be converted into cash) instead of investing. Is there a rule of thumb?
I pay about ~40% of my salary in rent, but am in good health and don't have any amazing debt or payment obligations.
