Please don’t read this as me telling you how to manage your finances, but I do similar to you. I save monthly for my car, a holiday etc etc.
For the sake of round numbers;
In - £1000
Holiday - £50
Bills - £500
Car - £50
Leaves £400 in my account. That’s my budget. I don’t need to worry about future pot transfers etc. It’s all done and dusted when I get paid with Salary Sorter.
Would this not solve your issue?
