Frequently Asked Questions

What is ROAS and what is a good ROAS?

ROAS (Return on Ad Spend) = Revenue from ads ÷ Ad spend. A ROAS of 4 means $4 revenue for every $1 spent. A 'good' ROAS depends on margins — ecommerce typically targets 3-5x, lead gen focuses on cost per lead instead.

How do I calculate Facebook ads ROI?

Facebook Ads ROI = (Revenue from FB ads − Ad spend − COGS) ÷ Ad spend × 100. Example: $10,000 revenue, $2,000 ad spend, $4,000 COGS → ROI = ($10,000 − $2,000 − $4,000) ÷ $2,000 × 100 = 200%. Our calculator does this instantly.

What is a good cost per acquisition (CPA)?

A good CPA must be less than your customer lifetime value (LTV). If your LTV is $200 and your CPA is $50, you have a 4:1 LTV:CAC ratio — excellent. If CPA exceeds your average order value, you're losing money on ads.

How do I improve my ad ROI?

Increase conversion rate (landing page testing), reduce CPA (audience targeting refinement), increase average order value (upsells/bundles), and cut underperforming ad sets. Also test creatives — ad fatigue kills performance after 7-14 days.

What is break-even ROAS?

Break-even ROAS = 1 ÷ Gross Margin. If your gross margin is 50%, your break-even ROAS is 2. Any ROAS above 2 is profitable, below 2 is losing money. Our calculator shows your break-even ROAS automatically.

Should I track ROAS or ROI for ads?

ROAS is simpler (revenue ÷ spend) and used by ad platforms. ROI factors in your product costs and gives a truer profitability picture. Use ROAS for quick optimization decisions, ROI for overall business profitability analysis.
