What Is an Advertising ROI Calculator?
An advertising ROI calculator measures the percentage return generated by your advertising investment. It compares the revenue attributed to your ads against the total cost of running those ads, expressing the result as a percentage that shows profitability at a glance.
Unlike surface-level metrics like clicks or impressions, advertising ROI connects spending directly to business outcomes. A campaign generating 500,000 impressions means nothing if it doesn't produce revenue exceeding costs—and this calculator makes that distinction crystal clear.
Marketing directors and CMOs use this metric to justify advertising budgets to leadership, compare performance across channels, and determine which campaigns deserve additional investment. Profitable campaigns typically show an ROI of 200–800%.
Advertising ROI Formula
The advertising ROI formula subtracts your total ad cost from the revenue generated, divides by the ad cost, and multiplies by 100 to express the result as a percentage.
Advertising ROI = ((Revenue - Ad Cost) ÷ Ad Cost) × 100 Example ROI Calculation
$500 ÷ 100,000 = 0.005 × 1,000 = $5.00
How to Calculate Advertising ROI
Follow these steps to accurately measure the return on your advertising investment and identify your most profitable campaigns.
Track Revenue from Advertising
Set up proper attribution tracking to measure revenue directly generated by your advertising campaigns. Use UTM parameters, conversion pixels, and CRM integration for accuracy.
Your Google Ads campaigns generated $24,500 in tracked revenue from 340 conversions last month.
Calculate Total Advertising Costs
Sum all costs associated with your advertising—platform ad spend, agency fees, creative production, and any technology costs for tracking and optimization.
Ad spend: $5,000 + Agency fee: $1,000 + Creative: $500 = $6,500 total cost.
Apply the ROI Formula
Subtract total costs from revenue, divide by total costs, and multiply by 100 to get your ROI percentage.
(($24,500 - $6,500) ÷ $6,500) × 100 = 276.9% ROI
Compare ROI Across Campaigns
Calculate ROI for each campaign or channel individually. This reveals which investments are most profitable and where to shift budget for maximum return.
Google Search: 350% ROI, Facebook: 180% ROI, Display: 95% ROI—shift budget toward search.
