Key Operating Metrics
We manage our business by tracking several operating metrics, including: daily active users, or DAUS, hours engaged, and
average bookings per daily active user, or ABPDAU. As a management team, we believe each of these operating metrics
provides useful information to investors and others. For information concerning these metrics as measured by us, see "Note
Regarding Operating Metrics" in the Appendix of this document.
Daily Active Users (DAUS). We define a DAU as a user who has logged in and visited Roblox through our website or
application on a unique registered account on a given calendar day. If a registered, logged in user visits Roblox more than once
within a 24-hour period that spans two calendar days, that user is counted as a DAU only for the first calendar day. We believe
this method better reflects global engagement on the platform compared to a method based purely on a calendar-day cutoff.
DAUS for a specified period is the average of the DAUS for each day during that period, so 30 days, for example, in the month of
September. Other companies, including companies in our industry, may calculate DAUS differently. We track DAUs as an
indicator of the size of the audience engaged on our platform.
Hours Engaged. We define hours engaged as the time spent by our users on the platform, which includes time spent in
experiences, which refer to the titles that have been created by developers, and within platform features such as chat and
avatar personalization. Users can personalize the size and body shape of their avatars as well as equip their avatars with items
acquired from the Avatar Marketplace, a marketplace that allows users to acquire items such as clothing, gear, simulated
gestures, or emotes, and other accessories.
Average Bookings per Daily Active User (ABPDAU). We define average bookings per DAU, or ABPDAU, as bookings in a
given period divided by the DAUS for such period. We use ABPDAU as a way to understand how we are monetizing across all of
our users through the sale of virtual currency and subscriptions.
