About This Module

The Marketing ROI Calculator quantifies how effectively your advertising dollars translate into profit. By comparing the profit generated by a campaign against the total amount spent, you get a clear percentage that tells you whether a campaign is worth repeating, scaling, or cutting.

What Is a Marketing ROI Calculator?

Marketing return on investment measures the net profit a campaign produces relative to its total cost. The formula subtracts ad spend from the profit generated, then divides by ad spend, yielding a percentage. A positive ROI means the campaign earned more than it cost; a negative ROI means it lost money. This metric is essential for data-driven marketing because it provides a single, comparable number across vastly different campaign types, channels, and budgets. This browser-based tool makes the calculation effortless and completely free.

How It Works

Enter the total profit generated by the campaign, which is the campaign revenue minus cost of goods sold, excluding the ad spend itself. Then enter the total ad spend, including creative production and agency fees. Click Calculate and the tool instantly shows your ROI percentage along with contextual interpretation. All processing happens in your browser with no data shared and no login required. Run the calculation for each campaign to build a performance comparison across your marketing portfolio.

Best Use Cases
