How much cash (if any) do you carry on you? According to a new survey, the amount of cash you should have on you is … $200. Why $200? Because it’s enough to handle a standard emergency – like if you’re at dinner and your credit card gets declined. Not surprisingly, not many people carry around that much cash. A survey from Money magazine found that 42 percent of people carry no more than $40 in cash, 30 percent carry between $41 and $99, 17 percent carry $100 to $199, and just 11 percent carry $200 or more.
