Break-Even Analysis Calculator
Calculate break-even point and contribution margin.
Break-Even Analysis Calculator models the sales volume or revenue required to cover costs in single-product or multi-product scenarios. Fixed costs are expenses that do not change directly with unit volume, such as rent, salaries, or software commitments, while variable costs rise with each unit sold. Contribution margin is selling price minus variable cost; it is the amount each sale contributes toward fixed costs and profit. In a multi-product mix, weighted contribution margin reflects how different products with different prices and costs combine at portfolio level. Break-even is the point where total contribution equals fixed costs, so profit is zero. This tool is useful for pricing, launch planning, and manufacturing decisions, but taxes, capacity limits, channel fees, returns, and demand uncertainty can change the real threshold.
