# Estimating our Croct MAU from GA4 before picking a plan

Asked by Colin W on 2025-05-14. Tags: pricing, mau, analytics.

Building the budget sheet before we commit to a plan. GA4 shows roughly 34k
active users per month for us, fairly stable over the last two quarters.

Can I treat that as our Croct MAU one to one, or do the definitions diverge? I
can imagine bots, consent banners, and where the measurement actually happens
all pulling the numbers apart, but I dont know in which direction or by how
much.

Would rather size the plan right the first time than get surprised either way.

Close, but not one to one. Croct MAU means unique users who interact with the
site in a month. Conceptually that is near GA4's monthly active users, but
they are measured by different scripts at different points with different
consent gating, so treat the GA4 figure as an estimate, not a mapping.

Direction-wise, the biggest systematic difference favors you: known bots do
not count toward MAU on paid plans once bot filtering is enabled. Raw
analytics counts usually include a bot share, so the Croct number typically
lands below the GA4 number rather than above it.

For plan sizing at 34k: that is above Growth's included 20k MAU, so your
realistic options are Growth with pay-as-you-go overage covering the
difference, or a Scale quote if you would rather have the volume in the base
plan. Extra volume is purchasable either way, it is not a hard wall, so the
cost of estimating slightly wrong is an overage line item rather than an
outage.

Practical suggestion: run a month on the free plan first. You get the actual
MAU number from your real traffic, and the budget sheet gets a measured input
instead of a converted one.

The measure-first suggestion is the answer I needed. One free month gives
me a real number for the sheet. Marking accepted.
