Three numbers and one honest look at the subscription. Count transport days, not attractions, before you buy a monthly ticket for a holiday.

The honest part
Break-even is roughly 6 Berlin AB days or 5 airport/Potsdam days per person. Estimate uses 24-hour tickets (AB 11.20 / ABC 12.90), small-group day tickets, and DB's Quer-durchs-Land day ticket for wider regional days.
For a short or central plan, single and 24-hour tickets are usually easier.
My rule: if you buy it only for this trip, cancel the same day the ticket appears correctly in your account.
