## Where is it mostly used?

In a business, the variable cost is mostly used and is an integral part while analysing the company’s break-even point. The break-even analysis is applied to scan the revenue or the unit that has to be sold to cover the total cost.

Break-even point in units = Fixed costs/(Sales price per unit – Variable cost per unit)
