2
Review Your Break-Even Results
The calculator displays three result cards -- Break-Even Units, Break-Even Revenue, and Net Profit / Loss. The Insights panel shows contribution margin, margin of safety, return on costs, and a revenue breakdown. Scroll down for the cost-volume-profit chart and scenario analysis table.

Example Calculation

A product-based business wants to find out how many units it must sell to cover all costs, given $30,000 in fixed costs, $20 variable cost per unit, and a $50 selling price with 1,500 expected unit sales.

Tips

Cut Fixed Costs to Lower Your Threshold

Reducing fixed costs directly lowers the break-even point. For example, cutting $5,000 from $30,000 in fixed costs (at a $30 contribution margin) drops the break-even from 1,000 to 834 units -- 167 fewer units to sell before turning a profit.

Raise Price for a Bigger Contribution Margin

A $5 price increase (from $50 to $55) raises the contribution margin from $30 to $35, reducing break-even units from 1,000 to 858 -- a 14.3% reduction. Small price adjustments can have outsized effects on profitability.

Trim Variable Costs Per Unit

Lowering variable costs by $3 (from $20 to $17) increases the contribution margin to $33, dropping break-even to 910 units -- a 9.1% improvement. Negotiate supplier rates or optimize production to achieve this.

Monitor Margin of Safety Regularly

A margin of safety above 20% gives you a healthy buffer. At 1,500 expected units and a 1,000-unit break-even, you have a 33.3% margin of safety -- meaning sales could drop by 500 units before you incur losses.

Understanding Your Break-Even Point in 2026

The Break-Even Point Calculator helps you determine the exact number of units you must sell -- and the revenue you must generate -- to cover all costs. By separating fixed and variable expenses, it reveals your contribution margin, margin of safety, and projected profit or loss at any sales volume. Whether you are launching a new product or evaluating pricing strategies in 2026, knowing your break-even point is foundational to sound financial planning.

The Break-Even Formula Explained

The break-even point depends on three variables: fixed costs, variable cost per unit, and selling price per unit. The core formulas are:

Contribution Margin = Selling Price - Variable Cost Per Unit
Break-Even Units = Fixed Costs / Contribution Margin
Break-Even Revenue = Break-Even Units x Selling Price
Margin of Safety = (Expected Units - Break-Even Units) / Expected Units x 100

Metric	Formula	Example ($30K FC, $20 VC, $50 Price)
Contribution Margin	Price - Variable Cost	$50 - $20 = $30
Break-Even Units	Fixed Costs / CM	$30,000 / $30 = 1,000
Break-Even Revenue	BE Units x Price	1,000 x $50 = $50,000
Margin of Safety	(Expected - BE) / Expected	(1,500 - 1,000) / 1,500 = 33.3%

💡 The contribution margin ratio (60% in this example) tells you how many cents of every revenue dollar go toward covering fixed costs. A ratio above 50% is considered strong in most industries.

Worked Example: Finding the Break-Even Point

A small manufacturer has $30,000 in fixed costs (rent, utilities, salaries). Each unit costs $20 in materials and labor and sells for $50. The company projects selling 1,500 units this period.

Contribution Margin: $50 - $20 = $30 per unit
Break-Even Units: $30,000 / $30 = 1,000 units
Break-Even Revenue: 1,000 x $50 = $50,000
Net Profit at 1,500 units: (1,500 x $50) - $30,000 - (1,500 x $20) = $75,000 - $60,000 = $15,000

At 1,500 units, the business earns $15,000 in profit with a 33.3% margin of safety -- meaning sales could fall by 500 units before hitting the break-even threshold.

💡 If you sell multiple products with different margins, consider using a weighted-average contribution margin. Our Business Break-Even Calculator can handle multi-product scenarios.

Pricing Sensitivity and Strategic Levers

Small changes in price or cost structure can dramatically shift the break-even point. A business with $30,000 in fixed costs and a $30 contribution margin breaks even at 1,000 units. But raising the price by just $5 increases the contribution margin to $35 and lowers break-even to 858 units -- 14.3% fewer. Similarly, cutting variable costs by $3 yields a $33 contribution margin and an 910-unit break-even.

Scenario	CM	Break-Even Units	Change
Baseline ($50 price, $20 VC)	$30	1,000	--
Price +$5 ($55)	$35	858	-14.3%
Variable cost -$3 ($17)	$33	910	-9.1%
Fixed costs -$5K ($25K)	$30	834	-16.7%

Understanding these levers is critical for 2026 planning. With rising input costs in many sectors, even modest efficiency gains or pricing adjustments can materially improve your break-even position and overall profitability.

Frequently Asked Questions

What is the break-even point?

The break-even point is the level of sales, in units or revenue, at which total costs exactly equal total revenue -- resulting in zero profit and zero loss. It represents the minimum performance threshold a business must achieve to avoid losing money. Every unit sold beyond this point contributes directly to profit.

How do I calculate break-even units?

Break-even units are calculated by dividing total fixed costs by the contribution margin per unit (selling price minus variable cost per unit). For example, $30,000 in fixed costs divided by a $30 contribution margin ($50 price minus $20 variable cost) equals 1,000 break-even units.

What is contribution margin and why does it matter?

Contribution margin is the difference between the selling price per unit and the variable cost per unit. It represents the portion of each sale that goes toward covering fixed costs and, eventually, generating profit. A higher contribution margin means fewer units need to be sold to break even, making the business less vulnerable to sales fluctuations.

What is a good margin of safety for a business?

A margin of safety above 20% is generally considered healthy. It measures how far actual or projected sales exceed the break-even point. For instance, if you expect to sell 1,500 units and break even at 1,000, your margin of safety is 33.3%, meaning sales could decline by a third before you start losing money.

Can this calculator be used for service businesses?

Yes. Instead of physical units, define a measurable unit of service such as billable hours, client sessions, or projects. The variable cost per unit becomes the direct cost of delivering one service unit, and the formula works identically.

How does changing fixed costs affect the break-even point?

Fixed costs and the break-even point move in direct proportion. If you double your fixed costs, your break-even point doubles. Conversely, reducing fixed costs by $5,000 (from $30,000 to $25,000 with a $30 contribution margin) lowers break-even from 1,000 to 834 units -- a meaningful improvement in financial risk.
