Answer:
MOS( in %) = 20%
Explanation:
Margin of safety (MOS) determines the amount by which expected sales exceeds the break-even point (BEP).
MOS can be calculated as follows:
MOS (units) = Budgeted sales - BEP
BEP= Fixed cost for the period / contribution per unit
Contribution per unit = Selling price - variable cost per unit
Contribution per unit = $10 - $5 = $ 5
BEP (units) = 100,000/ 5= 20,000
MOS (in units) = 25,000 - 20,000 = 5000 units
Margin of Safety as a %
(5000/25,000 ) × 100= 20 %
MOS( in %) = 20%
