What is a Break-Even Calculator?

A break-even calculator helps entrepreneurs and business owners determine the exact point at which total revenue equals total costs — producing neither profit nor loss. Knowing your break-even point is one of the most fundamental steps in validating a business model, setting prices, and planning production volumes. It answers the critical question: "How many units do I need to sell before I start making money?"

This tool uses the standard break-even formula: Break-Even Units = Fixed Costs ÷ (Selling Price − Variable Cost per Unit). The denominator — selling price minus variable cost — is called the contribution margin per unit. All calculations happen instantly in your browser; no data is sent to any server.


How to Use

  1. Enter your total Fixed Costs — costs that don't change regardless of sales volume (rent, salaries, software subscriptions).
  2. Enter the Variable Cost per Unit — what it costs you to produce or deliver each individual unit (materials, shipping, commissions).
  3. Enter the Selling Price per Unit — the price you charge customers for each unit.
  4. Click ✨ Calculate to see your break-even units, revenue, and a visual chart.

Frequently Asked Questions

Break-Even Units = Fixed Costs ÷ Contribution Margin per Unit, where Contribution Margin = Selling Price − Variable Cost per Unit. For example, if fixed costs are $10,000, selling price is $40, and variable cost is $15, then contribution margin is $25 and break-even is 400 units.

Fixed costs stay constant regardless of how many units you produce — rent, insurance, annual software licences, and salaried employees. Variable costs change directly with production volume — raw materials, per-unit packaging, sales commissions, and shipping fees. Some costs (semi-variable) have both components; split them as accurately as you can.
