Frequently Asked Questions

How do I calculate ROI?▾

Basic ROI = (Net Profit / Cost of Investment) x 100. Example: you spend $5,000 on marketing and generate $20,000 in revenue at 50% margin ($10,000 gross profit). ROI = ($10,000 - $5,000) / $5,000 x 100 = 100% ROI. Simple ROI does not account for time - a 100% ROI over 5 years is worse than a 100% ROI in 6 months. For time-sensitive investments, use NPV (Net Present Value) or IRR (Internal Rate of Return) calculations.

What is ROAS and how does it differ from ROI?▾

ROAS (Return on Ad Spend) = Revenue from ads / Ad spend. Example: $10,000 ad spend generates $40,000 revenue = 4x ROAS. ROI accounts for profit margin; ROAS uses gross revenue. A 4x ROAS on a 25% margin product breaks even (4 x 25% = 100% cost recovery). ROAS is simpler for media buyers comparing campaign efficiency; ROI is more meaningful for business decision-making because it accounts for actual profit. Always clarify which metric is being discussed in marketing conversations.

What is a good ROI for marketing?▾

Marketing ROI benchmarks vary by channel: email marketing averages 36-42x ROI (highest of any channel). SEO delivers 500-1000%+ over multi-year timeframes. Paid search (Google Ads) industry average is 2-4x ROAS, varying widely by vertical. Social media advertising typically delivers 1-3x ROAS. Traditional advertising (TV, radio, print) ROI is harder to measure directly. Compare ROI against your cost of capital and alternative investment opportunities, not just industry averages.

How do you calculate marketing ROI?▾

The basic formula compares the profit generated by marketing against its cost: subtract the marketing cost from the revenue attributed to it, then divide by the marketing cost, usually expressed as a percentage or a multiple. For example, spending 1,000 to generate 5,000 in attributable revenue gives a strong positive return. The key challenge is accurate attribution, correctly linking revenue to the specific marketing that drove it, and deciding whether to measure against revenue or profit, since profit accounts for the cost of goods. A calculator handles the arithmetic once you supply spend and results; the harder part is measuring which sales your marketing actually caused, which is where analytics and tracking come in.

What is a good ROI for a marketing campaign?▾

It varies widely by industry, channel, and business model, so there is no universal number, but the return must at least exceed the cost, and typically by a healthy margin to account for overhead and the cost of the product or service being sold. A common benchmark cited is a return of several times the spend, though what counts as good depends on your margins: a business with high margins can accept a lower revenue-based return than one with thin margins. More useful than a fixed target is comparison, measuring channels and campaigns against each other and against your break-even point, and improving over time. A campaign is worthwhile when its return comfortably exceeds its full cost and beats your alternatives.

Why is attribution important for measuring marketing ROI?▾

Because ROI is only meaningful if you correctly connect results to the marketing that caused them, and attribution is how you do that. Customers often interact with several touchpoints, an ad, a search, an email, before converting, so deciding which marketing gets credit for a sale is genuinely difficult and directly affects the ROI you calculate for each channel. Poor attribution leads to wrong conclusions, cutting a channel that actually contributed or overfunding one that merely got the last click. Different attribution models (first-touch, last-touch, multi-touch) assign credit differently. Getting attribution reasonably right, usually with analytics and tracking, is what makes ROI figures trustworthy enough to guide budget decisions rather than misleading them.
