I honestly don’t know how it works?
Gets paid into bank.
Withdraws money to put into envelopes.
Puts money into bank.
Direct debits go out.
Am I missing something or is it pointless?
I suppose you could withdraw your salary minus the amount needed for direct debits, then divvy that remaining amount up and be strict about not spending from your bank account.
It's too faffy for me to do it with actual cash, but there is something incredibly helpful about tangibly moving money around. When you're doing this in theory it can get a bit wooly.
e.g. you have £800 left after bills
Think OK £125 per week food shopping, that's £500
Then £70 petrol
£30 school bits for kids
£50 put aside for a couple of takeaways
£150 for other spends/emergencies and if not needed, goes into holiday fund.
And then life happens. The school shopping costs £50, you spend £140 on food on a couple of those weeks, although one week you're just under £100 on your main supermarket shop although neglect to count the £20 run to the corner shop. Petrol only costs £65 so you think you're up. The takeaways actually come to more like £80. You fritter a total of £10-20 on chocolate, drinks, coffee, little snacks/£1 toys. (etc).
That's over half your spare/emergency fund for the month gone and you might not even realise. You think you've got £150 spare and actually you've only got about £70. You can get to the end of the month and wonder where the money even went. If you're really unlucky you'll have an emergency cost at the end of the month for £100, think oh it's OK because I had that money spare, but then find you're £30 in the red.
So portioning it out really helps (whether digital or physical) because if you take £140 out of the supermarket envelope, you will have £15 less the next week and you'll need to physically take it from somewhere else or spend less at the supermarket. When you spend £5 less on the petrol, you can either stick it into an envelope that's feeling a bit light or you can bung it in the "treats" one, then when you want a chocolate bar or whatever, you know whether you can actually afford one. You can't "mentally spend" the money twice.
