ROAS vs ad ROI
ROAS is revenue per dollar of ad spend (revenue ÷ ad spend). ROI is profit per dollar of ad spend, expressed as a percentage: ROI = net profit ÷ ad spend × 100, where net profit subtracts cost of goods (via your gross margin) and the ad spend itself from revenue — not just the ad spend. A campaign can show a healthy 4.0 ROAS and still be a poor ROI once product costs are subtracted.

How to Calculate Ad Spend ROI
Enter your gross profit margin alongside spend, conversion rate, and order value. The calculator derives revenue and ROAS, multiplies revenue by your margin to get gross profit, subtracts ad spend to get net profit, and divides that by ad spend for your Marketing ROI %. The displayed Net Profit accounts for cost of goods, so it matches the ROI rather than contradicting it.
Worked example: ROAS vs ROI
$10,000 ad spend → $40,000 revenue at 35% gross margin:
- ROAS = $40,000 ÷ $10,000 = 4.0× (looks strong)
- Gross profit = $40,000 × 35% = $14,000
- Net profit after ads = $14,000 − $10,000 = $4,000
- Ad ROI = $4,000 ÷ $10,000 × 100 = 40%
Same campaign at 25% margin: gross profit = $10,000, net profit = $0, ROI = 0% despite 4.0× ROAS. This is why finance asks for ROI, not ROAS.

When to report ROI vs ROAS to finance
- ROAS for media buyers optimizing bids, creatives, and audiences day to day.
- ROI for CFO, board, and annual budget reviews — profit language, not revenue language.
- MER when attribution is unreliable and you need blended program truth.
Common mistakes
- Presenting 4× ROAS to finance without margin context — they will ask about COGS.
- Treating ROAS and ROI as interchangeable in reporting — different audiences need different metrics.
- Ignoring returns/refunds in revenue — net revenue lowers both ROAS and ROI.
- Using platform-reported revenue without reconciling to Shopify/ERP gross sales.
- Scaling on ROAS while ROI compresses — often means rising CAC or falling margin.
How to use this calculator
- Enter gross profit margin (required for ROI — this is what separates this page from basic ROAS).
- Enter ad spend, CPC, conversion rate, and order value (or revenue directly).
- Read ROAS for channel optimization and Marketing ROI % for profitability.
- Compare ROI to your hurdle rate (often 20–40% for growth-stage brands).
- Cross-check with MER for blended efficiency.
How to improve ad ROI
- Raise gross margin (pricing, COGS reduction) — improves ROI at the same ROAS.
- Improve conversion rate — more revenue and gross profit per click.
- Lower CAC via creative testing and audience refinement.
- Cut spend on sub-break-even campaigns (negative ROI).
- Run incrementality tests — reported ROI may be 30–60% lower than attributed.
Methodology & sources
ROI benchmarks assume COGS is captured via gross margin input. Attribution-inflated ROAS can overstate ROI by 30–60% on duplicated conversions — cross-check with MER before board reporting.

Return on Investment
Return on Investment measures the profitability of an investment by comparing the net profit (revenue minus all costs) to the total investment cost. In marketing, it considers all costs including media spend, creative production, technology, overhead, and operational expenses, making it a more comprehensive metric than ROAS which focuses specifically on ad spend.
Return on Ad Spend
Return on Ad Spend (ROAS) is a marketing performance metric that measures the revenue generated per dollar of advertising spend. Unlike ROI which considers all business costs, ROAS specifically evaluates advertising efficiency by comparing directly attributable revenue to ad spend. This metric is crucial for optimizing campaign performance, budget allocation, and overall marketing strategy.
Paid Media
Paid media encompasses all forms of advertising and promotional content where brands pay for placement, visibility, or engagement. This includes traditional advertising channels as well as digital platforms where payment is exchanged for audience reach, impressions, clicks, or other marketing objectives.
