For a firm, the breakeven point is the quantity of the sales required by the firm to cover its total cost, i.e., Total revenue = Total cost. At this quantity of sales the firm's net income is zero.

We know that:

$Q(P-VC) - F = EBIT$

F includes both fixed operating cost and fixed financing cost.

Breakeven quantity is the quantity where EBIT = 0. So, we solve for Q where EBIT = 0.

$Q=\frac{(\text{Total Fixed Cost})}{(P-VC)}$

Example

Let's say we have the following data about a company:

Price per unit = $8

Variable costs = $6
