Can someone explain to mw how pots work when you have averaged costs on a SOA.
I understand fixed monthly costs. For example £400 for groceries. All supermarket spends come out of that pot. Great.
How do people do non fixes costs such as birthdays. Say I put in £50 a month. If I have £100 in after two months and have 5 birthdays the following month, spending £20 each. So pot falls to zero. Then the next month I need £100 for Christmas. So now I am in negative. Do people have a constant float? So it always has a chunk in.
Am I overthinking this?
