A study by JPMorgan has found that your average American small business has about 27 days worth of reserve cash on hand to cover expenses if inflows suddenly stopped, according to
Bloomberg. This was the conclusion reached after analyzing 470 million transactions by 570,000 small businesses last year. While 27 days is the average, the data showed great variability from this figure depending on the type of business: restaurants, for instance, actually had an average of just 16 days of cash reserve, while real estate companies had about 47.
