I’d definitely find this useful. For example; we are currently paying out for fees for our first house and to make sure this is easily identifiable, I have a section in my spending spreadsheet that keeps track.
I don’t really want this to be part of my overall spending, so having a dedicated pot that shows me it’s own balance and transactions spent from that balance would be handy. My spreadsheet has an opening balance for our savings and then entries for fees and any added savings over the months, with a total spent and a total balance remaining, nothing fancy.
However I’m still firmly in the Summary boat that it’s easier to ‘commit’ spend rather than have it come out of a dedicated bills pot. As I do a lot of my budgeting in a spreadsheet, I just take the ‘spending’ figure from this and input into Monzo. That means I don’t really take too much notice of the overall account balance and just keep an eye on the summary ‘left to spend’ figure, which mirrors what it shown on my spreadsheet that I update weekly.
