Answer:
The excess of budgeted or actual sales over the break-even volume of sales.
Explanation:
The margin of safety is a measure in the break-even analysis that calculates either in units or amount terms the safe region for a business over break even point where there is no profit or no loss. This tells us how much the sales can fall before the company reaches break even.
For example, A company has 10000 units of budgeted sale while its break even point is at 8000 units. Thus, the margin of safety for such a company would be,
This means that the company is selling 2000 units in excess of its break-even quantity and that the sales can fall by 2000 units before the company reaches a point where it is earning no profit or no loss(break even).
