# How to check whether the winning paywall still pays back the ad spend that bought it

Find out whether the paywall that converts more trials also earns back the ad spend that bought it. In the Revenue report, select **Install (App)** as the start event and **Subscribe (App)** as the revenue event. Then select **Day 0-30** as the view and group by **Channel** and **Ad Creative**. Compare cumulative return on ad spend (ROAS) with **Total Cost**, **Paying Users**, and **Total Revenue** for Paywall A and Paywall B, then export the table as a CSV file if needed. To set up this report step by step, watch the video.
