Break-Even Point
Definition
The break-even point is the level of sales at which total revenue exactly equals total costs, resulting in zero profit or loss. Knowing the break-even point helps startups understand the minimum sales volume or revenue needed to cover all fixed and variable costs before generating any profit.
Formula
Overview
The break-even point is where a business transitions from losing money to making money on a per-period basis. It can be expressed in units sold or in revenue dollars. For subscription businesses, it is often framed as the number of paying customers needed to cover all costs.
The calculation requires three inputs: fixed costs (expenses that do not change with volume, like rent and salaries), price per unit, and variable cost per unit. Dividing fixed costs by the contribution margin per unit yields the break-even volume. Alternatively, dividing fixed costs by the contribution margin ratio yields break-even revenue.
For startups, the break-even point serves as a critical planning milestone. Understanding how many customers or how much revenue is needed to break even informs pricing decisions, hiring plans, and fundraising targets. Many seed-stage companies set a goal to reach break-even within a specific runway window as a backstop against fundraising risk.
Example
Fixed costs of $50K/month, subscription price of $100/month, variable cost of $20/month: break-even = $50K ÷ ($100 − $20) = 625 customers.
