## How to Calculate MOS using the Calculator

In order to calculate the margin of safety using the calculator, the user only has to insert the following details into the calculator.

Actual Sales – It is the sum of the actual sales (net of returns) made by the Company during the accounting period for which you calculate the margin of safety. In addition, we can obtain the value of the actual sales by multiplying the actual sales unit by the selling price per unit. These details can be taken from the Profit and Loss Account of the company.

Sales at BEP – It is the level of sales at which the company neither makes any profit or loss. In other words, it is a no-profit no-loss situation for the company where it just covers all the variable costs for the product or service from the revenue generated. For calculating breakeven sales, we divide fixed cost from contribution per unit.
