## Computation

In the linear Cost-Volume-Profit Analysis model,^{[2]} the **break-even point** (in terms of Unit Sales (X)) can be directly computed in terms of Total Revenue (TR) and Total Costs (TC) as:

where:

**TFC**is**Total Fixed Costs**,**P**is**Unit Sale Price**, and**V**is**Unit Variable Cost**.

The Break-Even Point can alternatively be computed as the point where Contribution equals Fixed Costs.

The quantity is of interest in its own right, and is called the Unit Contribution Margin (C): it is the marginal profit per unit, or alternatively the portion of each sale that contributes to Fixed Costs. Thus the break-even point can be more simply computed as the point where Total Contribution = Total Fixed Cost:

In currency units (sales proceeds) to reach break-even, one can use the above calculation and multiply by Price, or equivalently use the Contribution Margin Ratio (Unit Contribution Margin over Price) to compute it as:

R=C Where R is revenue generated C is cost incurred i.e. Fixed costs + Variable Costs or Q X P(Price per unit)=FC + Q X VC(Price per unit) Q X P – Q X VC=FC Q (P-VC)=FC or Q=FC/P-VC=Break Even Point
