Break Even Calculator

This break even calculator shows exactly how many units you need to sell to cover all your costs and reach your break-even point. Enter your fixed costs, variable cost per unit, and selling price, and it works out the break-even point in units, the revenue needed, and your contribution margin instantly.

It is built for business owners, entrepreneurs, and financial planners who want a fast break-even analysis before setting a price, launching a product, or committing to a sales target. Add an optional target profit, explore what-if scenarios with sliders, and read a live chart of revenue versus total cost.

Private by design: every calculation runs entirely in your browser. None of the costs, prices, or figures you enter are ever uploaded to a server, stored, or shared.

How to Calculate Your Break-Even Point

Enter your costs and price

Fill in Fixed Costs (rent, salaries, insurance), Variable Cost per Unit (materials, packaging, shipping per item), and Selling Price per Unit. Results update instantly as you type — there is no calculate button to press.

Review your results

See four key metrics at a glance: the Break-Even Point in units, the Break-Even Revenue needed, the Contribution Margin per unit, and the Margin Ratio as a percentage of selling price.

Set a target profit (optional)

Enter a desired profit amount to see how many additional units and how much revenue you need beyond break-even to reach your goal. A dashed line for the target also appears on the chart.

Explore what-if scenarios

Open the What-If Scenarios panel and drag the sliders to adjust your selling price or variable cost by up to 50% in either direction. The adjusted break-even point updates live so you can test pricing before committing.

Frequently Asked Questions

What is the break-even point?

The break-even point is the number of units you need to sell so that total revenue exactly covers total costs — both fixed and variable. At this point your profit is zero; every unit sold beyond it generates profit.

How do you calculate the break-even point in units?

Divide your fixed costs by the contribution margin: Break-Even Units = Fixed Costs ÷ (Selling Price per Unit − Variable Cost per Unit). This calculator runs that formula for you and rounds up to whole units the moment you enter your numbers.

How do I find the break-even point in sales revenue?

Multiply the break-even units by your selling price per unit. The calculator shows this as Break-Even Revenue — the total sales you need to bring in before you start making a profit.

What are fixed costs versus variable costs?

Fixed costs stay the same regardless of how much you produce — rent, salaries, insurance, loan payments, and subscriptions. Variable costs change with every unit — raw materials, packaging, shipping per item, and sales commissions.

What is the contribution margin?

The contribution margin is the selling price minus the variable cost per unit. It is how much each sale contributes toward covering your fixed costs. A higher contribution margin means fewer units are needed to break even.

Why does my break-even change when fixed costs change?

Break-even units equal fixed costs divided by the contribution margin, so higher fixed costs push the break-even point up and lower fixed costs bring it down. Use the What-If Scenarios sliders to see the same effect from changing your price or variable cost.

What does it mean when the result shows a dash?

A dash appears when your selling price is less than or equal to your variable cost per unit. In that case every unit loses money, so there is no break-even point. Raise your selling price or lower your variable cost to make break-even possible.
