How to use the Return on Ad Spend Calculator.
Return on ad spend uses attributed revenue divided by advertising spend. It does not measure net profit, and results depend on the attribution window and treatment of refunds.
Make the workflow fit your task.
Align attributed revenue and advertising spend to the same campaign and reporting convention. State the attribution window and treatment of refunds, taxes and repeat purchases. Divide revenue by spend and keep profitability questions separate from this ratio.

Load this input into the prompt, then copy it to WebAct to try the task. Your result may differ from the illustration.
Decisions and troubleshooting.
Does a 3× ROAS mean the campaign earned three times its spend in profit?
No. ROAS uses revenue; product, fulfillment and other costs are not automatically deducted.
Why do the ad platform and analytics system report different ROAS?
Attribution models, windows and revenue definitions may differ. Reconcile those settings before judging the discrepancy.
