Cost vs Revenue
How it works
Break-even analysis tells you exactly how many units you need to sell to cover all your costs. Below that number, you lose money. Above it, every additional sale is pure profit (minus variable costs). It's the single most important number for pricing decisions.
The formula
Why it matters for your business
Every business decision affects your break-even point. Hiring someone raises fixed costs. Changing your price shifts the entire equation. Understanding this relationship helps you make confident decisions about pricing, hiring, and expansion.
Pro tip
Most founders forget that break-even isn't just about units — it's about time. If you sell 10 units/day and need 500 to break even, that's 50 days of runway consumed. Connect this to your runway calculator for the full picture.
