Understanding Margin of Safety
The margin of safety is the difference between a firm’s actual or planned output/sales and its break-even output/sales. It shows how much sales can fall before the business starts making a loss.
For Gowda Chanda Inc., the margin of safety is the gap between the planned output and the break-even output.
Calculating Price per Tonne
