Break-Even Formula
Break-even units = Fixed Costs ÷ (Price − Variable Cost). The difference between price and variable cost is "contribution margin" — what's left after making the product to cover fixed costs and generate profit.
Fixed vs Variable
Fixed costs stay the same regardless of sales: rent, salaries, insurance, software subscriptions. Variable costs scale per unit: raw materials, shipping, per-transaction fees. Knowing the split is critical for pricing.
Use Cases
New product launch: how many must we sell to justify development? Pricing tests: at what price does a discount pay off? Capacity planning: can the market support enough volume? Investor pitches: realistic timeline to profitability?
FAQ
What if my margin is negative?
Break-even is impossible — each sale loses money. Either raise prices or cut variable costs before scaling.
