How do I calculate my true CAC, not just what the ad platform reports?

Platform-reported CAC only counts that platform's spend against that platform's claimed conversions, it ignores agency fees, tools, creative production and the fact that Meta and Google are both taking credit for the same sale. True (blended) CAC is total acquisition spend across every channel and vendor, divided by total new customers in that period, full stop. Track this monthly per channel and blended, the gap between platform-reported and blended CAC is usually where founders discover they're less profitable than the dashboard suggested.
