The break-even point is where Total Revenue = Total Costs (fixed + variable), i.e. profit = 0. It is calculated as: $Q_{BE} = \dfrac{\text{Fixed Costs}}{\text{Selling Price} - \text{Variable Cost per unit}}$. Below $Q_{BE}$, the process operates at a loss; above it, profit is generated. Understanding the break-even point is essential for pricing bioproducts, evaluating capital investment decisions, and assessing process scale-up viability.
