Triple Whale Total Impact is the metric inside Triple Whale that estimates how much revenue your combined marketing spend actually generated, as opposed to what each ad platform claims on its own. It's an attempt to answer one question: if you strip out the overlap between Meta, Google, and TikTok all taking credit for the same sale, what's left?

That's the whole point of it. Platform-reported ROAS is notoriously inflated because every ad network uses its own attribution window and its own pixel, and none of them know what the others are doing. Triple Whale Total Impact exists to correct for that by modeling incremental revenue across all channels at once, instead of adding up five dashboards that each think they deserve full credit.
