Break-Even Point Calculator
Find how many units you need to sell to cover your costs.
About this tool
Calculates how many units you need to sell (and how much revenue that represents) before a product or service starts turning a profit — the point where total revenue exactly covers your fixed and variable costs, with nothing left over yet.
Everything is calculated locally in your browser — nothing you enter is sent anywhere.
Frequently asked questions
- What's the difference between fixed and variable costs?
- Fixed costs (rent, salaries, software subscriptions) stay the same regardless of how many units you sell. Variable costs (materials, per-unit shipping, payment processing fees) scale directly with each additional unit sold.
- What is "contribution margin"?
- The amount each unit sold contributes toward covering fixed costs, after its own variable cost is subtracted (price − variable cost). Once enough units are sold that their combined contribution margin covers all fixed costs, you've broken even — every unit after that is profit.
- What if price is lower than variable cost?
- You'd be losing money on every unit sold, so there's no break-even point — no volume of sales would ever cover costs at that price.
