What is Break Even ROAS?
Break Even ROAS is the minimum Return on Ad Spend your advertising campaigns must achieve before ad costs are fully covered by revenue. At Break Even ROAS, you are not generating profit from advertising — but you are not losing money either. Any ROAS above this threshold means each ad-driven sale adds to net profit. Any ROAS below it means advertising is actively eroding your margin on every sale.
The formula is straightforward: Break Even ROAS = Selling Price ÷ Total Expense. Total Expense covers all variable costs per unit — product cost, shipping, packaging, marketplace commission, and payment processing fees. This gives you a single, actionable number to set as your campaign ROAS floor.
How to Calculate Break Even ROAS
To calculate your Break Even ROAS manually, follow these steps:
- 1Calculate Marketplace Fee: Selling Price × Marketplace Fee %
- 2Calculate Payment Fee: Selling Price × Payment Gateway Fee %
- 3Calculate Total Expense: Product Cost + Shipping + Packaging + Marketplace Fee + Payment Fee
- 4Calculate Break Even ROAS: Selling Price ÷ Total Expense
Worked Example
Selling $100 · Cost $40 · Shipping $10 · Packaging $5 · Marketplace 10% ($10) · Payment 3% ($3)
Total Expense = $68 · Break Even ROAS = $100 ÷ $68 = 1.47x
Why Break Even ROAS Matters in Ecommerce
Most ecommerce sellers optimise for a "good" ROAS without knowing what their specific break-even threshold is. A business with thin margins may need a ROAS of 3 or higher just to break even — while another product with stronger margins can be profitable at 1.5x. Without calculating your own Break Even ROAS, setting target ROAS values in ad campaigns is guesswork.
For sellers on Amazon, Flipkart, Shopify, or any marketplace running paid ads, Break Even ROAS is the foundation of every profitable advertising decision. It tells you exactly when to scale a campaign and exactly when to pause one — based on your own cost structure, not industry benchmarks.
Tips to Improve Your ROAS
Actionable ways to either increase your effective ROAS or lower your break-even threshold.
Improve product page conversion rate
Better images, clearer benefit copy, and strong reviews convert more ad clicks into sales without increasing spend.
Increase average order value
Bundles and cross-sells generate more revenue per click, improving ROAS without changing your ad budget.
Tighten audience targeting
Narrow targeting reduces wasted impressions and lowers cost per click on high-intent audiences.
Reduce product cost (COGS)
A lower break-even threshold makes campaigns profitable at a wider range of ROAS levels.
