cription

SAL

Amount obtained from sales

SBE

Break-even sales (amount that must be obtained from sales to break even)

MOS

Margin of safety (portion of sales amount above break-even point)

I

Example

What is the margin of safety ([MOS]) when the sales amount ([SAL]) is $1,200,000 and the
break-even sales amount ([SBE]) is $1,000,000?
• You can calculate the break-even sales amount ([SBE]) using Break-Even Point (page

15-11-1).

• You can also calculate the sales amount ([SAL]) or break-even sales amount ([SBE]) by

inputting the other two values and tapping the button for the result you want.
