Break-even Volume
334 units

You must sell 334 units ($16,700.00 in revenue) to break even.

Required Revenue$16,700.00
Contribution Margin / Unit$30.00
Contribution Margin Ratio60%
Theoretical Exact Units333.33 units
Unit Contribution Analysis:
Each unit sold at $50.00 provides $30.00 towards paying off your $10,000.00 fixed overhead (a 60% contribution ratio). After selling 334 units, all fixed costs are completely covered and subsequent unit sales contribute pure operating profit.

How It Works

The Break-even Calculator identifies the exact sales volume needed to cover all fixed and variable operating costs, yielding zero profit and zero loss.

It also calculates contribution margin per unit and determines how many additional units must be sold to achieve a specific target profit goal.

Formula & Calculation

Break-even Volume Formula

Break-even Units = (Fixed Costs + Target Profit) / (Price − Variable Cost)
Fixed Costs=Overhead expenses independent of sales volume (rent, salaries)
Price − Variable Cost=Unit contribution margin
Target Profit=Optional profit goal (set to 0 for pure break-even)

Price per unit must strictly exceed variable cost per unit; otherwise, every unit sold generates a loss and break-even is mathematically impossible.

Step-by-Step Example

Example: Manufacturing a Widget

Find the break-even point with $10,000 fixed costs, $50 selling price, and $20 variable cost:

Step 1: Calculate unit contribution margin: $50.00 − $20.00→ $30.00 contribution/unit
Step 2: Divide fixed overhead by unit contribution: $10,000 / $30.00→ 333.33 units
Step 3: Round up to nearest whole unit: ceil(333.33)→ 334 units
Step 4: Calculate break-even gross revenue: 334 units × $50.00→ $16,700.00

The business must sell 334 units ($16,700 in revenue) to cover all operating costs.

Assumptions & Edge Cases

  • Contribution Margin Must Be Positive: If the selling price is less than or equal to variable cost per unit, the contribution margin is zero or negative, making cost recovery impossible. The calculator rejects this condition with an inline alert.
  • Discrete Unit Ceilings: In practical business operations, fractional units cannot be sold. Break-even volume is rounded up to the nearest whole integer unit.

Frequently Asked Questions

What expenses count as fixed costs versus variable costs?

Fixed costs remain constant regardless of production volume (office rent, insurance, administrative salaries). Variable costs scale directly with output (raw materials, packaging, direct assembly labor, payment processing fees).
