Ad Spend ROI Calculator

A good ROAS varies by industry, but generally 4:1 (400%) is considered healthy for most e-commerce businesses. Break-even ROAS depends on your profit margins—if your margins are 50%, you need at least 2:1 ROAS to break even. High-margin products can be profitable at lower ROAS, while low-margin products require higher ROAS.

A good CPA should be significantly lower than your Customer Lifetime Value (CLV). As a rule of thumb, your CPA should be no more than 1/3 of your CLV to maintain healthy profit margins. For example, if a customer is worth $300 over time, your CPA should ideally be under $100.

Focus on improving your Quality Score (Google Ads) or Relevance Score (Facebook Ads) to lower costs. Test different audiences, ad creatives, and landing pages. Use retargeting to reach warm audiences with higher conversion rates. Implement proper conversion tracking to identify your best-performing campaigns and allocate budget accordingly.

It depends on your business model. E-commerce businesses often focus on ROAS because it directly measures revenue generated. Lead generation businesses typically focus on CPA since conversions (leads) need further qualification. For subscription businesses, consider Customer Acquisition ROI which factors in lifetime value.

CLV helps you understand how much you can afford to spend acquiring a customer. If your CLV is $500 and CPA is $50, you have a 10x return on your acquisition investment over the customer relationship. This perspective allows you to invest more aggressively in acquisition while competitors focused only on immediate ROAS underspend.
