Break-Even Calculator
Calculate the break-even point for a business or product in units and revenue.
The Formula
Break-Even Revenue = Fixed Costs / Gross Margin %
Contribution margin = $80 − $32 = $48
Break-even = $12,000 / $48
= 250 units / month
What Is the Break-Even Point?
The break-even point is the level of sales at which total revenue exactly equals total costs. Below it, you lose money. Above it, every additional unit sold generates profit. For any new product, business, or pricing decision, knowing the break-even point tells you the minimum you need to sell before the venture pays for itself. It is one of the most fundamental and useful calculations in business finance, and it takes only three inputs: fixed costs, variable cost per unit, and selling price.
Fixed vs. Variable Costs
Fixed costs stay constant regardless of how much you produce or sell — rent, salaries, insurance, software subscriptions, and equipment leases are examples. Variable costs change with volume — raw materials, packaging, shipping, sales commissions, and payment processing fees. The break-even formula is straightforward: Break-Even Units equals Fixed Costs divided by the Contribution Margin, where Contribution Margin equals Selling Price minus Variable Cost Per Unit. The contribution margin is what each unit contributes toward covering fixed costs before generating profit.
Using Break-Even Analysis in the Real World
Break-even analysis is useful before launching a product, setting a price, evaluating a large order, or deciding whether to expand. If your break-even requires selling 10,000 units per month but your realistic market is 3,000 units, the business model needs adjustment — raise the price, cut variable costs, or reduce fixed overhead. Running this calculation before committing resources prevents costly mistakes and forces you to stress-test your assumptions.
Frequently Asked Questions
What is the break-even formula?
Break-Even Units = Fixed Costs divided by (Selling Price minus Variable Cost Per Unit). To find break-even revenue, multiply break-even units by the selling price. Alternatively, Break-Even Revenue = Fixed Costs divided by the Contribution Margin Ratio, where Contribution Margin Ratio = (Selling Price minus Variable Cost) divided by Selling Price.
What are fixed vs. variable costs?
Fixed costs remain constant regardless of production volume — rent, salaries, insurance, loan payments, and software subscriptions. Variable costs scale with output — raw materials, packaging, shipping, and sales commissions. Some costs are semi-variable, like utilities, which have a fixed base plus a usage-based component.
How do I lower my break-even point?
Three levers: raise your selling price (increases contribution margin), reduce variable costs per unit (same effect), or cut fixed costs (lowers the hurdle entirely). In practice, a combination of all three is often most effective. Small improvements across all three levers can meaningfully reduce the number of units needed to reach profitability.
What is contribution margin?
Contribution margin is selling price minus variable cost per unit. It represents how much each sale contributes toward covering fixed costs. Once fixed costs are fully covered, contribution margin converts directly to profit. A higher contribution margin means fewer units needed to break even and faster profit growth above the break-even point.
Can break-even analysis apply to services?
Absolutely. Instead of units, think in terms of hours billed, clients served, or projects completed. A freelancer with $3,000 per month in fixed expenses and a $150 hourly rate with $10 in variable costs per hour needs to bill about 21 hours monthly to break even. Every billable hour beyond that generates profit.
