ROAS Calculator
Measure the financial return generated from advertising spend and compute your exact breakeven ROAS threshold.
What is the ROAS Calculator?
Return on Ad Spend (ROAS) calculation measures the gross revenue generated directly for every currency unit invested in commercial marketing and advertising campaigns over time. It divides total attributed commercial sales revenue by aggregate advertising expenditure, modeling break-even performance thresholds and customer acquisition margins across active ad channels. This empowers performance marketing teams to identify high-performing advertising channels, eliminate unprofitable campaigns, and scale profitable customer acquisition budgets systematically.
The ROAS Calculator determines Return on Ad Spend (ROAS) ratio, campaign ROI percentage, net profit generated, and the minimum breakeven ROAS required to cover product margins.

Return on Ad Spend (ROAS) Formula
Calculates Return on Ad Spend (ROAS) by dividing gross ad-generated revenue by advertising expenditure, and computes the breakeven ROAS threshold required based on product gross margin.
Core ROAS Calculator Inputs & Terminology
Return on Ad Spend, calculated as total revenue generated divided by ad spend (e.g. 4.0x or 4:1).
The minimum ROAS needed so ad revenue covers both ad spend and product cost of goods sold (1 / Gross Margin %).
Net profit from advertising divided by ad spend expressed as a percentage.
The percentage of revenue retained after deducting direct product manufacturing or acquisition costs.
