Break-even is the point where total revenue equals total costs, so the business makes neither a profit nor a loss. It is a vital tool for decision-making.
盈亏平衡点是总收入等于总成本的点，因此企业既不盈利也不亏损。它是决策的重要工具。
Break-even point (units) = Fixed costs ÷ (Selling price per unit – Variable cost per unit)
盈亏平衡点（单位数） = 固定成本 ÷ （单位售价 – 单位可变成本）
Margin of safety (units) = Actual output – Break-even output
安全边际（单位数） = 实际产出 – 盈亏平衡产出
The break-even chart shows the fixed cost line, total cost line, and total revenue line; the intersection is the break-even point. Limitations: it assumes all output is sold, costs are linear, and only one product.

毛利率 (%) = (毛利润 ÷ 收入) × 100
Net profit margin (%) = (Net profit ÷ Revenue) × 100
