According to RTrack’s MAU analysis for Roblox in January 2021, approximately 199 Million users were active on the platform in the 30 days preceding January 31st.
Estimated through RTrack’s monthly Roblox user sampling, the figure for January 2021 is just shy of 200 Million monthly active users.
Shown below in the interactive graph are RTrack’s MAU estimates going back to December 2019. Unfortunately MAU estimates were paused for 4 months between August and November 2020, and this gap has been filled in with extrapolated data, based on changes in other statistics such as web traffic, platform concurrent user estimates, and playtime estimates.
RTrack uses random user sampling to estimate MAU every month. 80,000 random user accounts are sampled, and the date on which their account was last online is used to determine whether they were active within the past month. Using an up to date figure for Roblox’s total user count, the percentage of sample online in the past month is then used with the number of accounts to calculate an estimate for that month’s MAU.
A Rolling 30 day active user graph & MAU over counts overtime, along with many other sets of data recorded about the Roblox platform including weekly & monthly engagement hour estimates are available with the RTrack Complete plan.
Disclaimer: This figure is an estimate, calculated using random sampling. It has not been confirmed or verified by Roblox, and is not an official figure. This should only be used as an indication of the general trend of MAU, not as an exact figure, and there is always a risk that this estimate is inaccurate. The only definite values of Roblox monthly active user counts are released by Roblox, on the Roblox blog.
