Break-even analysis tells you exactly how much you need to sell to cover all your costs — the point where revenue equals expenses and profit is zero.
Formula: Break-even Point = Fixed Costs / (Selling Price - Variable Cost per Unit). If fixed costs are $50,000, selling price is $25 per unit, and variable cost is $15 per unit, the break-even point is 5,000 units.
This analysis is essential before launching a product or business. It answers the critical question: "Is this venture financially viable?" Every unit sold beyond the break-even point generates pure profit.
