When marketers report a “10× return on ad spend”, they usually mean revenue / spend — completely ignoring gross margin. The honest ROI on a $10,000 campaign that generates $35,000 in revenue depends on your margin. At 60% gross margin, your real net ROI is 110%. At 25% margin (typical for retail), it’s a measly −13% — you actually lost money. This calculator does the proper math.

Why ROAS Lies (And ROI Tells the Truth)
ROAS (Return on Ad Spend) = Revenue / Ad Spend. This is a vanity metric. It tells you nothing about whether you actually made money.
True Marketing ROI = (Revenue × Gross Margin − Spend) / Spend. This is what you actually pocket. The difference between the two is enormous in low-margin businesses.
ROI Benchmarks by Channel
| Channel | Typical Net ROI | Notes |
|---|---|---|
| SEO content | 200–500% | High effort upfront, compounds for years |
| Email marketing (existing list) | 3000–4000% | Highest ROI of any channel |
| Google Ads (search intent) | 50–200% | Depends heavily on keyword cost vs CPL |
| Meta / Instagram Ads | 0–150% | Strong for impulse + retargeting; weak cold |
| Influencer partnerships | 50–300% | Highly variable; pick alignment over reach |
| Affiliate marketing | 100–400% | Pay only on conversion; great for SaaS |
| YouTube ads | 20–150% | Brand-building more than direct response |
Hidden Costs Most Calculators Ignore
- Production cost — agency fees, copywriting, design, photography. Often 20–50% of media spend.
- Tools and software — landing pages, email, analytics. ~$200–2,000/month.
- Your time / team time — internal labour at fair hourly rates.
- Refunds and returns — typically 5–15% of revenue, depending on industry.
- CAC payback time — if you’re acquiring subscription customers, the cash deployed today won’t come back for 6–18 months. Plan for cash flow.
Scaling a Profitable Campaign
- ROI > 100%, payback < 3 months: scale aggressively, double the budget weekly until ROI compresses.
- ROI 50–100%, payback < 6 months: scale gradually, optimise creative and audience.
- ROI 0–50%, payback > 6 months: hold spend, run experiments to improve creative / targeting.
- ROI < 0%: kill the campaign, redirect to better-performing channels.
