What Is ROAS and How Do You Calculate It?

ROAS tells you how much revenue each unit of ad spend returns.

Formula

ROAS = ad revenue ÷ ad spend. Spend 1,000 and earn 4,000: ROAS 4.

Break-even ROAS

Break-even ROAS = 1 ÷ gross margin. With 40% margin, break-even ROAS is 2.5.

Limits

ROAS ignores repeat purchases, organic halo and platform over-attribution. Pair it with MER and CAC.

Common mistakes to avoid

• Ignoring negative keywords and search term reports
• Judging success on clicks instead of enquiries and sales
• Following up leads hours or days too late
• Changing too many things at once, so you can't tell what worked

Quick checklist before you start

• Clear goal and budget for the next three months
• Weekly review of results and search terms
• A follow-up process for every enquiry
• Accounts and data in your business name
• Landing page that matches the offer

Key takeaway

ROAS (return on ad spend) explained: formula, examples, good benchmarks by margin and why ROAS alone can mislead. Start with one clear goal, measure results from day one and keep accounts and data in your own name, so you stay in control whatever partner you work with.
