To measure the ROI of a SaaS explainer video, use the baseline formula:
ROI = (Revenue generated from the video – Cost of the video) ÷ Cost of the video × 100%
Then track key SaaS metrics before and after: landing page conversion rates, demo/trial sign-ups, trial-to-paid conversion, sales cycle length, CAC, churn/retention, and support ticket volume. For example, if a landing page conversion rate increases from 2% to 3.5%, the resulting additional revenue can be compared to the video cost to calculate ROI.
