Frequently Asked Questions
What is ROAS and how does it differ from ROI?
ROAS (Return on Ad Spend) measures gross revenue generated for every dollar spent directly on advertising (Revenue / Ad Spend). ROI (Return on Investment) measures actual net profit generated after subtracting all campaign costs including product cost of goods sold (COGS), agency retainers, shipping, and software fees ((Net Profit / Total Costs) * 100).
What is a good ROAS for digital advertising campaigns?
A common general benchmark is 4.0x (400% ROAS), meaning $4 in revenue for every $1 in ad spend. However, the required ROAS depends entirely on your product profit margin. A digital software company with 90% margins can be profitable at 1.5x ROAS, whereas a physical retailer with 25% margins requires 4.0x or higher to break even.
How do you calculate breakeven ROAS?
Breakeven ROAS is calculated by dividing 1 by your profit margin before advertising (Breakeven ROAS = 1 / Profit Margin). For example, if your product sells for $100 and costs $50 to make and deliver (50% margin), your breakeven ROAS is 1 / 0.50 = 2.0x (200%). Any campaign achieving above 2.0x ROAS is generating net profit.
Why should I include COGS and agency fees in my ROAS calculations?
Relying solely on ad platform dashboard numbers (like Meta or Google Ads ROAS) creates a false sense of profitability. If you spend $5,000 to generate $15,000 in sales (3.0x platform ROAS), but your product costs $12,000 to manufacture and fulfill, you actually lost $2,000. Including COGS reveals true bottom-line cash flow.
What is CPA and how does it impact ROAS?
CPA (Cost Per Acquisition) is the total ad spend divided by the number of paying customers acquired. If your Average Order Value (AOV) is $100 and your CPA is $25, your ROAS is 4.0x. Lowering CPA through conversion rate optimization directly boosts your ROAS.
Is my advertising budget and revenue data private?
Yes. All financial modeling, ROAS ratios, and funnel calculations run strictly inside your local browser memory. No budget figures, store revenues, or marketing metrics are sent to remote servers.
