Nobody signs up for twelve subscriptions on purpose. They arrive one at a time, each one small and reasonable. The trouble is not any single charge. It is that several of them tend to renew in the same week as your rent.
See them on the calendar

List every renewal with its date
Cancel the ones you would not sign up for today
Move the rest away from your tightest week
It is less about cutting back and more about timing. The same subscriptions, renewed on better days, can quietly lift your lowest balance of the month.
