Frequent Asked Questions
What is a good Return on Investment (ROI) for Google Ads?
While a “good” ROI varies significantly by industry and profit margins, a common baseline benchmark is 200%, or a 2:1 ratio—meaning you earn $2 in revenue for every $1 spent on ads. For e-commerce businesses, a healthy target is often 400% (4:1) or higher. You can use this calculator to establish your current baseline and set realistic future targets.
How do I calculate my Google Ads Return on Ad Spend (ROAS)?
ROAS is calculated by dividing your total conversion revenue by your total ad spend. For example, if you spend $1,000 on a Google Ads campaign and it generates $5,000 in sales, your ROAS is 500% (or 5:1). This calculator automates that math to give you a clear picture of your campaign’s gross profitability.
What metrics do I need to prepare before using this calculator?
To get the most accurate estimate, you should have a few baseline figures ready. At a minimum, you need your projected or current ad budget, average Cost Per Click (CPC), expected landing page conversion rate, and your Average Order Value (AOV) or customer lifetime value.
What is the difference between ROI and ROAS in digital advertising?
ROAS (Return on Ad Spend) strictly measures the gross revenue generated directly from your ad spend without factoring in your business costs. ROI (Return on Investment) is a broader metric that calculates your actual net profit by factoring in your product margins, agency fees, and operating expenses. This calculator helps you look at the raw performance data to determine if the campaigns will ultimately be profitable.
Why might my projected Google Ads ROI be lower than expected?
A low projected ROI usually comes down to three factors: a high Cost Per Click (CPC) relative to your product price, a low landing page conversion rate, or targeting overly broad keywords that drive irrelevant traffic. If your results in the calculator look unprofitable, try adjusting your target conversion rate or average order value to see what operational changes are needed to make the campaign viable.
