Measure your Return on Ad Spend to evaluate how effectively your advertising budget is generating revenue.
Revenue from Ads ($)
Ad Spend ($)
Use this calculator to measure ad revenue efficiency and compare campaign performance.
Add the amount spent on the campaign, ad group, channel, or keyword set you want to evaluate. Keep the time period aligned with your revenue data.
Add revenue attributed to the same advertising activity. Use platform data, analytics attribution, or ecommerce reporting consistently.
Run the calculator to divide revenue by spend. Review the result as a ratio or percentage to understand how efficiently ads produce sales.
Compare the result with target ROAS, break-even ROAS, margin, and channel benchmarks before scaling, pausing, or restructuring campaigns.
Make faster advertising decisions with a clear return-on-spend benchmark.
01
Understand which campaigns generate the most revenue for each dollar of media spend across Google Ads, Meta, marketplaces, or other paid channels.
02
Use ROAS with margin and fulfillment costs to avoid scaling campaigns that look strong in revenue but weak in contribution profit.
03
Shift spend toward campaigns, products, and audiences that clear your target ROAS while reducing waste in lower-return segments.
04
Turn ad efficiency into a shared target for marketers, finance teams, and agency partners reviewing campaign performance.
ROAS means return on ad spend. It measures how much revenue advertising generates for every dollar spent on campaigns, ad groups, channels, or keywords.
ROAS equals revenue attributed to ads divided by ad spend. If a campaign spends $2,000 and generates $10,000 in revenue, the ROAS is 5x or 500%.
A good ROAS depends on gross margin, fulfillment cost, customer lifetime value, and growth goals. A 4x ROAS may be strong for one brand and unprofitable for another with lower margins.
Break-even ROAS is the return needed to cover costs before profit. It is typically based on gross margin, so lower-margin products require a higher ROAS to stay profitable.
ROAS focuses on revenue generated by ad spend, while ROI compares profit against total investment. ROAS is useful for campaign efficiency, but ROI gives a fuller profitability view.
Use revenue attributed to the same campaign and time window as the ad spend. For better decisions, also review new versus returning customers, refunds, discounts, and contribution margin.
