Calculating Retention Rates


I am brainstorming how I will calculate my user retention rates in Metabase. Previously I have done so by taking this month's number of users subtracting last month's number of users and dividing by the current total. I am wondering if this would be possible to do in a custom formula with the different time series? Or perhaps with two different questions?

Thanks in advance for your ideas!
