I get paid nine months a year, and during those months, I save for the other three. Right now, it is one such month where I do not have any income coming in, but I have more than enough saved in my savings account to cover the expenses. So, my spending plan shows a negative number, which is disconcerting (and more importantly, is misleading - I have the money in dedicated savings accounts that I transfer to my checking account as necessary). There should be a way to account for spending from your saved liquid money.
