Break-even ROAS

Break-even ROAS is the minimum Return On Ad Spend an advertising campaign must achieve to cover the cost of the goods sold (COGS) and the advertising expenditure itself, resulting in zero profit and zero loss.

Definition

Break-even ROAS is the minimum return on ad spend needed to cover all costs associated with a sale. It's calculated as:

Break-even ROAS = 1 ÷ Profit Margin

Example Calculation

  • Product sells for $100
  • Cost of goods: $30
  • Shipping: $10
  • Payment processing: $5
  • Other variable costs: $5
  • Profit margin: ($100 - $50) ÷ $100 = 50%
  • Break-even ROAS: 1 ÷ 0.50 = 2.0x

This means you need at least $2 in revenue for every $1 spent on ads to break even. Anything above 2.0x is profit; below is loss.

Why It's Your Most Important Number

Break-even ROAS sets your campaign benchmarks. Your prospecting campaigns should aim for 1-1.5x break-even ROAS, while retargeting should exceed it by 2-3x. Your blended ROAS across all campaigns should consistently beat break-even for sustainable growth.

Why It Matters

Without knowing your break-even ROAS, you're flying blind with your ad spend. It's the single number that tells you whether a campaign is profitable or losing money. Every advertising decision — budget allocation, scaling, killing underperforming campaigns — should be measured against your break-even ROAS. It's the foundation of profitable advertising.

Examples

  • •An e-commerce store sells a pair of shoes for $120. The total COGS (including manufacturing, shipping, and fees) is $72. The profit margin is ($120 - $72) / $120 = 40%. The Break-even ROAS is 1 / 0.4 = 2.5x.
  • •A subscription box company has a 60% profit margin on its first box. Their Break-even ROAS is 1 / 0.6 = 1.67x. They set a Target ROAS of 3.0x to ensure healthy profit.
  • •A business with low profit margins of 20% needs to achieve a Break-even ROAS of 5x (1 / 0.2). Any campaign performance below a 5x ROAS is unprofitable.

Common Mistakes

  • ✕Forgetting to include all variable costs in COGS, such as payment processing fees, shipping, and packaging, which leads to an inaccurately low Break-even ROAS.
  • ✕Using a single, company-wide Break-even ROAS for products or services with vastly different profit margins.
  • ✕Confusing Break-even ROAS with Target ROAS. The break-even point is the minimum floor, while the target ROAS should be set higher to achieve desired profit goals.
  • ✕Ignoring the metric entirely and focusing only on revenue, which can lead to scaling unprofitable advertising campaigns.
