I’m also a long termer.
i now also have chase savings pots. So my general expenses are in my current account aka ynab, things like pet insurance, costs for dd, bills etc.
then I put food money into my chase current account
then I have chase savings pots (you can have 10) with sinking funds eg holiday, vet bills, water bill , car savings , £1k of emergency savings
and I’ve also just started premium bonds which is where I plan to build up longer term emergency funds. I’m doing it on what I spend without saving per month, so essentially my income minus what I currently save. Have a princely sum of £75 here atm!!
