E-Commerce Unit Economics & Break-Even ROAS Algebra

How to accurately compute true landed costs, platform referral commissions, and maximum allowable CAC

Break-Even ROAS Calculation Formula

Break-Even ROAS represents the exact advertising return required for a product sale to generate zero net profit or loss:

Break-Even ROAS = Retail Price / (Retail Price - Non-Ad Costs)

If a product sells for $50 and landed COGS + marketplace fees total $25, your gross contribution is $25, meaning your target ROAS must exceed 2.00x to achieve positive cash flow.

Margin % vs. Markup % Distinction

Conflating margin and markup is the #1 reason e-commerce brands misprice products and run out of working capital:

  • Net Margin %: (Net Profit / Selling Price) × 100. Margin can never exceed 100%.
  • Markup %: (Net Profit / Total Cost) × 100. A product costing $20 and sold for $60 has a 200% markup and a 66.7% margin.

Net Profit=Price−(Landed Cost+Platform Fees+Fulfillment+CAC)Break-Even ROAS=PriceGross Contribution\begin{gathered} \text{Net Profit} = \text{Price} - (\text{Landed Cost} + \text{Platform Fees} + \text{Fulfillment} + \text{CAC}) \\[10pt] \text{Break-Even ROAS} = \frac{\text{Price}}{\text{Gross Contribution}} \end{gathered}

Net profit is computed by subtracting all landed product expenses, marketplace referral commission (e.g. 15% Amazon or 6.5% Etsy), fulfillment pick-and-pack, and ad spend (CAC). Break-even ROAS represents the minimum ad return required to avoid losing money.

WooCommerce Wholesale & B2B Margin — Frequently Asked Questions

Authoritative answers to common questions, regulatory rules, and compliance guidance.

What is the difference between Margin % and Markup %?
Margin % is calculated as Net Profit divided by Selling Price. Markup % is Net Profit divided by Total Unit Cost. For instance, a product made for $50 and sold for $100 has a 50% margin and a 100% markup.
How do I calculate my Break-Even Target ROAS?
Divide the retail price by your gross contribution margin (Price minus all non-ad expenses). If a product sells for $50 and non-ad costs are $25, your gross contribution is $25, and your break-even ROAS is 2.0x.
What hidden fees should e-commerce sellers watch out for?
Be sure to factor in returns and restock fees (typically 3-8% in fashion/apparel), seasonal Amazon storage surcharges in Q4, and payment gateway chargeback buffer funds.
What is the difference between profit margin and markup percentage?
Profit margin is profit divided by revenue (the percentage of sales retained as profit). Markup is profit divided by cost of goods sold (how much cost is marked up to establish the selling price). A 50% markup produces a 33.3% gross margin.
What is considered a good gross profit margin for a business?
Benchmark gross margins vary by industry: SaaS and digital products typically achieve 70% to 85%, wholesale e-commerce averages 35% to 50%, and retail or grocery stores typically operate between 20% and 30%.
