Break-Even Analysis Calculator for Startups

Break-even analysis is one of the first financial exercises every startup should perform. It answers the critical question: how many units (or customers) do you need to cover all costs? The formula is simple: Break-Even Units = Fixed Costs / (Price per Unit − Variable Cost per Unit). For example, if your monthly fixed costs are $10,000, you sell at $50, and each unit costs $20 to produce, you need 10,000 / (50 − 20) = 334 units per month to break even.

Use this tool to model different pricing strategies before launch. Try raising your price by 10% and see how dramatically the break-even point drops. Investors often ask for break-even projections in pitch decks — this calculator gives you the numbers instantly. You can also stress-test scenarios: what if variable costs rise 15%? What if fixed costs double after hiring? Knowing your break-even point helps you set realistic revenue targets and manage your runway effectively.
