Does such a thing exist?

I'm a little handy with the old Excel macros and I'm thinking about producing a spreadsheet thingy that works out how much you'll need to allocate for forthcoming bills and other regular payments then tells you exactly how much money you're allowed to spend on a day-to-day basis. Kind of an automated pocket money programme/nagger.

Is there such a package already out there that anyone knows of, or should I go for it and get programming? :think:
