What is Google Ads ROI?
Return on Investment (ROI) is a performance measure used to evaluate the efficiency or profitability of an investment or compare the efficiency of a number of different investments. In the context of PPC, ROI indicates the financial success of paid advertising campaigns. It’s calculated by dividing the net profit (the profit after advertising costs) by the total advertising costs.
Google Ads ROI Formula
The ROI of a PPC campaign is calculated by our ROI calculator by taking the revenue that results from the campaign, subtracting the overall costs, then dividing by the overall costs. The result is expressed as a percentage. If the ROI is positive, the campaign has been profitable. If it’s negative, the costs have outweighed the revenue.

Google Ads ROI = ((Total Ad Revenue – Total Ad Cost) / Total Ad Cost) × 100
Explanation:
For a completed campaign:
- Total Ad Cost = Google Ad Spend + Additional Costs (e.g., agency fees)
- Total Ad Revenue = Actual revenue generated from the campaign
For a future campaign:
- Total Ad Revenue = Target Revenue
- Required Conversions = Target Revenue ÷ Average Revenue per Conversion
- Required Clicks = (Required Conversions ÷ Expected Conversion Rate) × 100
- Total Ad Cost = Required Clicks × Expected Cost-Per-Click (CPC)
This formula helps you estimate or evaluate the return on your advertising investment with accuracy.
How to Calculate Google Ads ROI with Example
Let’s say you run an online shoe store and decide to set up a PPC campaign for a new line of running shoes. Here’s how you might calculate the ROI:
- Cost of PPC Campaign: You spend $1,000 on your PPC campaign.
- Revenue Generated: The campaign results in 50 sales of the running shoes. Each pair of shoes sells for $100, so the total revenue is $5,000.
- Gross Profit: To calculate the gross profit, you need to subtract the cost of the goods sold from the revenue. If each pair of shoes costs you $40, the cost of the goods sold is $40 * 50 = $2,000. So, the gross profit is $5,000 (revenue) – $2,000 (cost of goods sold) = $3,000.
- Net Profit: To calculate the net profit, you subtract the cost of the PPC campaign from the gross profit. So, the net profit is $3,000 (gross profit) – $1,000 (PPC campaign cost) = $2,000.
- ROI: Finally, to calculate the ROI, you divide the net profit by the cost of the PPC campaign and multiply by 100 to get a percentage. So, the ROI is ($2,000 / $1,000) * 100 = 200%.
This means that for every dollar you spent on the PPC campaign, you made a return of $2. Therefore, this PPC campaign has a positive ROI.
Understanding Google Ads Costs
Before diving into ROI calculations, it’s essential to grasp the various costs associated with Google Ads. The primary cost is the Cost Per Click (CPC), which is the amount you pay each time someone clicks on your ad. Other cost models include Cost Per Mille (CPM), where you pay per thousand impressions, and Cost Per Acquisition (CPA), focusing on the cost per conversion. Additionally, there are indirect costs such as agency fees, creative production, and software tools. Understanding these costs is vital for accurate ROI calculation from the ROI calculator, as they all contribute to the total investment in your campaigns. By factoring in all expenses, you can get a true picture of your campaign’s profitability.
ROAS vs. ROI: What’s the Difference?
While both ROAS (Return on Ad Spend) and ROI (Return on Investment) are crucial metrics in digital marketing, they serve different purposes. ROAS measures the revenue generated for every dollar spent on advertising, focusing solely on ad performance. It’s calculated as (Revenue / Ad Spend). On the other hand, ROI considers the overall profitability by including all costs, not just ad spend. It’s calculated as ((Revenue – Total Costs) / Total Costs). For example, if you spend $1,000 on ads and generate $5,000 in revenue, your ROAS is 5:1. However, if your total costs (including production and fees) are $2,000, your ROI would be (($5,000 – $2,000) / $2,000) = 150%. Understanding the distinction helps you choose the right metric for your goals—ROAS for ad efficiency and ROI for overall profitability.
Metric | Formula | Focus | Use Case |
---|---|---|---|
ROI | (Revenue – Total Costs) / Total Costs | Overall profitability | Evaluating the success of the entire campaign, including all expenses |
ROAS | Revenue / Ad Spend | Ad performance | Measuring the effectiveness of ad spend in generating revenue |
Understanding the Google Ads ROI Result
Your Google Ads ROI is a critical indicator of how efficiently your ad spend is generating revenue. Performance can vary by industry, competition, and campaign setup, but here’s how to interpret your results:
- High ROI (Strong Performance):
A return of around 400% ROAS or higher (roughly a 4:1 ratio) means you’re earning $4 in revenue for every $1 spent—this is considered excellent performance and signals an efficient, profitable campaign. - Average ROI (Acceptable Performance):
A 200% ROAS (about 2:1) is generally seen as a benchmark across industries. At this level, you’re doubling your investment and achieving a positive return, though there’s still room for improvement. - Low ROI (Poor Performance):
If your ROAS is below 100% (less than $1 back for each $1 spent), your campaign is underperforming. This typically means your ad spend is exceeding the revenue generated, resulting in a negative return. In this case, adjustments to targeting, creative, or bidding strategy are necessary.
Understanding these ROI thresholds can help you determine whether your ads are driving growth or draining your budget—and when it’s time to optimize.
