Can someone tell me what this number represents please?
That’s the total of all your envelopes. If everything is correct, that should equal the total of all your accounts on the Accounts tab.
That’s the total amount you have remaining in the budget. It includes all the money still in your envelopes including any Unallocated funds.
From this it looks like you have 488.33 in other, non-monthly envelopes, yes?
The ‘Total’ specifically comes from the funds you have available in the Accounts you’re tracking. So, between the two Accounts you have, you have a total of 1150 available to budget with.
Hope that helps!
