If upgrading (say from a $10/month to a $20/month plan 3 days into the subscription):

1. Calculate the fraction of the period used to this point under the previous plan, x.

3 days /30 days = 0.1 = x

Note: This is approximate, since months can have different numbers of days, there are leap years, etc.

2. Multiply x by the previous plan's billing amount, amount_prev to get how much to credit the customer back, credit.
