Break-Even Calculator

Find exactly how many units you need to sell to cover your costs. See your profit zone at different sales volumes.

Selling price must be higher than variable cost per unit to break even.

What Is Break-Even Analysis?

Break-even analysis tells you the exact point where your revenue equals your total costs — no profit, no loss. Every unit sold beyond that point is pure profit. Every unit below it means you're losing money.

For product teams, break-even analysis answers the critical question: "How many units do I need to sell before this product starts making money?" This informs production run sizes, marketing budgets, pricing decisions, and go/no-go calls on new SKUs.

Break-Even Formula

Break-Even Units = Fixed Costs ÷ (Selling Price − Variable Cost per Unit)

The denominator (Selling Price − Variable Cost) is called the Contribution Margin per Unit

Worked Example

You're launching a premium protein bar. Your numbers:

  • Fixed costs: $12,000 (equipment lease, packaging design, certifications)
  • Variable cost per unit: $3.20 (ingredients, packaging, fulfilment)
  • Selling price: $6.99

Break-Even = $12,000 ÷ ($6.99 − $3.20) = $12,000 ÷ $3.79 = 3,167 units

You need to sell 3,167 bars to cover all costs. Unit 3,168 onward is profit ($3.79 per unit).

Fixed Costs vs Variable Costs

Fixed Costs Variable Costs
Rent / lease payments Raw materials / ingredients
Equipment depreciation Packaging per unit
Salaries (non-production) Shipping / fulfilment per unit
Insurance Payment processing fees
Packaging design (one-off) Sales commissions
Certifications / compliance Marketplace referral fees (e.g. Amazon 15%)

When to Use Break-Even Analysis

  • Before a production run — Know the minimum viable order quantity
  • Pricing decisions — See how price changes affect your break-even point
  • New SKU launches — Compare break-even across product variants
  • Channel planning — Different channels have different variable costs (DTC vs wholesale vs Amazon)
  • Investor conversations — Show the path to profitability with real numbers
  • Marketing budget setting — If break-even is 5,000 units at $2 CAC, marketing budget is $10,000

Break-Even by Industry

Typical contribution margins and what they mean for break-even speed:

Industry Typical Contribution Margin Break-Even Implication
Food & Beverage (DTC) 45-65% Moderate — offset by high fixed marketing spend
Beauty & Skincare 60-80% Fast break-even on low fixed costs
Supplements 65-80% Fast — but compliance/testing fixed costs high
Apparel 50-70% Moderate — inventory risk adds effective cost
Electronics / Hardware 25-45% Slow — high fixed R&D, tooling, certification
Food & Beverage (Wholesale) 20-35% Slow — need volume; thin margins per unit

Common Mistakes in Break-Even Analysis

  1. Forgetting channel fees — Amazon's 15% referral + FBA fees are variable costs, not fixed
  2. Using COGS instead of true variable cost — Include shipping, payment processing, returns
  3. Ignoring marketing spend — Customer acquisition cost is effectively variable at scale
  4. One break-even for multiple channels — DTC, wholesale, and marketplace have different economics
  5. Static analysis — Your break-even shifts as you scale (volume discounts lower variable cost)

Frequently Asked Questions

What's the difference between break-even in units and break-even in revenue?

Break-even units tells you how many products you need to sell. Break-even revenue is that number multiplied by your selling price — it's the total sales dollars needed. Both represent the same point; the revenue figure is useful for cash flow planning and sales targets.

What is contribution margin?

Contribution margin is the selling price minus variable cost per unit. It's the amount each unit "contributes" toward covering your fixed costs. Once fixed costs are covered, the contribution margin becomes your profit per unit. A higher contribution margin means faster break-even.

Should I include marketing costs as fixed or variable?

It depends. Brand-building spend (PR, content, design) is fixed. Performance marketing (paid ads with a known CAC) is effectively variable — you spend more as you sell more. For most e-commerce businesses, model paid acquisition as a variable cost by adding your target CAC to the variable cost per unit.

How does break-even relate to minimum order quantity (MOQ)?

If your manufacturer's MOQ is less than your break-even units, you'll need to sell through your entire first batch and reorder before reaching profitability. If MOQ exceeds break-even, you'll be profitable within your first order — but you need the upfront capital. Compare MOQ to break-even to understand your capital requirements.

What if I can never break even?

If your selling price is equal to or less than your variable cost, you can never break even — you lose money on every unit sold regardless of volume. You need to either increase price, reduce variable costs, or kill the product. This calculator will alert you when this occurs.

How do I factor in Amazon or Shopify fees?

Platform fees are variable costs. Amazon charges ~15% referral fee plus FBA fees per unit. Shopify charges payment processing (2.9% + $0.30). Add these per-unit costs to your variable cost input. For Amazon: Variable Cost = COGS + FBA fee + (Price × 0.15).

How accurate is break-even analysis for new products?

Break-even analysis is only as good as your cost estimates. For new products, variable costs often decrease at scale (volume discounts) and fixed costs are sometimes underestimated (unexpected certification, redesign). Run scenarios at your best-case and worst-case cost estimates to get a range rather than a single number.
