How it is calculated
ARPU = revenue for the period ÷ active users over that same period. The denominator includes every active user, even those who paid nothing that period, so ARPU usually comes out lower than the average paying customer's spend.
If you need the figure for paying users specifically, that's ARPPU (Average Revenue Per Paying User) — the same formula, but the denominator only counts users who paid at least once during the period. The gap between ARPU and ARPPU shows what share of users are monetized at all.
ARPU for periods of different lengths isn't directly comparable — monthly and annual ARPU are calculated separately and don't relate by a simple ×12, because the set of active users in a month usually isn't the same as over a year.
