Margin of Safety & Operating Leverage

Concept

Margin of Safety

The margin of safety measures how far sales can drop before the company reaches break-even. Margin of Safety = Actual Sales − Break-Even Sales. It can be expressed in dollars, units, or as a percentage.

Example

Calculation

Actual sales = $400,000. Break-even sales = $250,000. Margin of Safety = $150,000 or 37.5% ($150,000 / $400,000). Sales can drop by 37.5% before the company starts losing money.

Concept

Operating Leverage

Operating leverage measures how sensitive net income is to changes in sales. Companies with HIGH fixed costs and LOW variable costs have HIGH operating leverage — a small change in sales produces a large change in profit.

Key Point

Degree of Operating Leverage

DOL = Contribution Margin / Net Operating Income. If DOL = 4, then a 10% increase in sales produces a 40% increase in net operating income.
