Discrepancy in MixPanel Total: 4259 vs. 4652 Explained

·Aug 12, 2025 05:14 AM·

Hi guys, I am a bit caught up here, how come MixPanel is showing the wrong total? It shows 4259, but when I calculate each month, total comes out to be 4652. Am I missing out on something?

A represents the total number of unique users across the entire time window (January to July). Each user is counted only once, regardless of how many months they were active. B, on the other hand, is the sum of monthly unique users from January through July. In this case, the same user can be counted multiple times—once for each month they were active, so the total may include duplicates across months. Summary
A = unique users across the full period (deduplicated) which is what Mixpanel does
B = sum of unique users per month (not deduplicated) which is what you expect Mixpanel to show.
