Finds the break-even point for a product or business: the number of units you must sell so that revenue exactly covers fixed costs plus variable costs. It also shows break-even revenue and the contribution margin per unit.
Launching a product or running a business without knowing the break-even point risks pricing that can never cover costs. The calculation separates what must be sold before profit exists, which anchors pricing, marketing, and budget decisions.
