Breakeven analysis tells you the sales level where you stop losing money. The margin of safety answers the follow-up question: how far can sales drop before you're back at breakeven?

What is the margin of safety?

Margin of Safety = Actual Sales − Breakeven Sales

It's the cushion between what a company is actually selling and the point where it would start losing money.

Worked example

Say breakeven sales are $87,500, and actual sales are $107,500:

Margin of Safety = $107,500 − $87,500 = $20,000

Sales could drop by $20,000 before the company crosses back below breakeven and starts losing money.

A bigger margin of safety means more room to absorb a sales downturn before it becomes a loss. It's a quick way to gauge how exposed a company is to a drop in demand.
