As per the display in "App Store Connect > Sales and Trends > Subscriptions > Summary", I'm wanting to understand how to calculate the 'Active paid subscriptions' figure for a particular period using only the subscription event data. This is for further analysis and calculation outside of App Store Connect. For example, if at the start of April I have 500 active paid subscriptions, then at the end of April I have 550 active paid subscriptions, what are the calculation of Subscription events that would make up this figure? I'd presume the formula would be: End of period subscriptions = start of period subscriptions + activations (includes trials) + conversions to standard price + reactivations - refunds - trial only activations - cancellations However when I compare the above calculation against what is reported by 'Active paid subscriptions' at the start and end of a period in App Store Connect it is not the same. What is the calculation of events across a period that determines the current 'Active paid subscriptions' figure?
