Karl Bücher in the context of Break-even (economics)

The break-even point (BEP) in economics, business—and specifically cost accounting—is the point at which total cost and total revenue are equal, i.e. "even". In layperson's terms, after all costs are paid for there is neither profit nor loss. In economics specifically, the term has a broader definition; even if there is no net loss or gain, and one has "broken even", opportunity costs have been covered and capital has received the risk-adjusted, expected return. The break-even analysis was developed by Karl Bücher and Johann Friedrich Schär.
