How much cash on hand should one have?
There are two or three issues here. One is, how quickly can you get cash out of your investments? If you had an unexpected expense, if you suddenly needed more cash than you have on hand, how long would it take to get money out of your Scott Trade account or wherever it is? I have a TD Ameritrade account which is pretty similar, and it just takes a couple of days to get money out. I'm hard pressed to think of a time when I literally needed a bunch of cash TODAY with no advance warning. What sudden bills is one likely to have? A medical bill, perhaps. But hey, just a few weeks ago I had to go to the emergency room with a medical problem, and it's not like they demanded cash on the table before they'd help me. I just got the bill, maybe 3 weeks after the event. I've never decided to move and then actually moved 2 days later. These things take SOME planning. Etc. Second, how much risk are you willing to tolerate? If you have your money in the stock market, the market could go down just as you need the cash. That's not even a worst case scenario, extreme scenario. After all, if the economy gets bad, the stock market could go down, and the same fact could result in your employer laying you off. That said, you could reduce this risk by keeping some of your money in a low-risk investment, like some high-quality bonds. Third, you want to have cash to cover the more modest, routine expenses. Like make sure you always have enough cash on hand to pay the rent or mortgage, buy food, and so on. And fourth, you want to keep a cushion against bookkeeping mistakes. I've had twice in my life that I've overdrawn a checking account, not because I was broke, but because I messed up my records and thought I had more money in the account than I really did. It's impossible to give exact numbers without knowing a lot about your income and expenses. But for myself: I keep a cushion of $1,000 to $1,5000 in my checking account, on top of all regular bills that I know I'll have to pay in the next month, to cover modest unexpected expenses and mistakes. I pay most of my bills by credit card for convenience --and pay the balance in full when I get the bill so I don't pay interest -- so I don't need a lot of cushion. I used to keep 2 to 3 months pay in an account invested in bonds and very safe stocks, something that wouldn't lose much value even in bad times. Since my daughter started college I've run this down to less than 1 months pay, and instead of replacing that money I'm instead putting my spare money into more general stocks, which is admittedly riskier. So between the two accounts I have a little over 2 months pay, which I think is low, but as I say, I'm trying to get my kids through college so I've run down my savings some. I think if I had more than 6 months pay in easily-liquidated assets, then unless I expected to need a bunch of cash for something, buying a new house or some such, I'd be transferring that to a retirement account with tax advantages.
