Ad Spend ROAS Calculator
Calculate return on ad spend (ROAS) and ROI from an advertising campaign.
About this calculator
Marketers reporting on ad campaign performance need two related but distinct numbers, ROAS and ROI, and mixing them up (or reporting only one) can make a campaign look better or worse than it actually was. This calculator takes revenue generated from ads and total ad spend, then computes ROAS as revenue divided by spend (shown as a ratio like 4:1) and ROI as net profit (revenue minus spend) divided by spend, expressed as a percentage. It's meant for marketers, agencies and small business owners evaluating whether a campaign was profitable and by how much, not just whether it generated more revenue than it cost. The distinction matters because a campaign can have a high ROAS ratio while still being only marginally profitable once the spend itself is subtracted out, this calculator surfaces both figures side by side instead of leaving you to compute ROI separately and risk missing that nuance.
Worked example
$8,000 revenue from $2,000 spend
Result: 4.00:1 ROAS, 300% ROI
