Break-even analysis separates fixed costs from costs that rise with each sale. This calculator assumes the price and variable cost per unit remain constant across the volume you test. It runs locally in your browser, and no account is required.

What does a break-even calculator show?
A break-even calculator finds how many units you must sell before revenue covers fixed and variable costs. Enter fixed costs, selling price and variable cost per unit to see the whole-unit sales target, required revenue, contribution margin and optional volumes for a target profit or planned sales level.
How to use
- 1Enter fixed costs. Use the total overhead for one period or project, such as rent, salaries, software and insurance for a month.
- 2Add unit economics. Enter the selling price and the variable cost attached to one item, booking or service unit.
- 3Read the break-even target. Review the required whole units, revenue, contribution per unit and contribution ratio.
- 4Test a scenario. Open Planning scenarios to add a target profit or planned unit volume, then compare the projected result.
Who it's for
- Small business owners setting a monthly sales target that covers rent, salaries and other overhead.
- Product teams testing whether a proposed price leaves enough contribution per unit to recover launch costs.
- Freelancers and service firms treating each project, booking or billable hour as one unit when planning capacity.
- Event and course organizers estimating how many tickets or seats must sell before a fixed venue or production budget is recovered.
FAQ
Is this break-even calculator free?
Yes. You can calculate break-even units, revenue, contribution margin, target-profit volume and projected profit without signing up or paying. There is no fixed calculation limit, and the inputs stay available only in the current browser session unless you copy the results.
Are my costs or prices uploaded?
No. The calculations run in your browser. The fixed costs, price, variable cost, profit goal and planned sales volume you enter are not sent to a calculation server or saved to an account.
What is the break-even point formula?
Break-even units equal fixed costs divided by contribution per unit. Contribution per unit equals selling price minus variable cost. For fixed costs of 12,000, a price of 95 and a variable cost of 38, contribution is 57 and the break-even point is 211 whole units after rounding up.
How do you calculate break-even revenue?
Multiply the whole-unit break-even target by the selling price to get the actionable revenue target. In continuous accounting terms, you can also divide fixed costs by the contribution margin ratio. The two figures can differ slightly when the exact unit result contains a fraction and must be rounded up.
What if variable cost is higher than the selling price?
There is no break-even volume when variable cost equals or exceeds the selling price. Each additional unit adds no contribution, or increases the loss, so selling more cannot recover fixed costs. Raise the price or lower the unit cost before calculating a viable target.
What is margin of safety in break-even analysis?
Margin of safety measures how far planned sales sit above the break-even point. This calculator reports that cushion as a percentage of planned units. A negative result means the plan remains below break-even; a positive result shows how much volume could fall before the business reaches the break-even line.
Can I use this for services instead of products?
Yes. Define one unit as a booking, project, subscription, ticket or billable hour. Use a consistent period for fixed costs and planned volume, and include only costs that change with each additional unit in the variable cost field.
