Also, when working out your budgeting, be sure to include any debts that you're working on. I tend to pay mine off in lump sums, as you can see (those numbers are accurate unfortunately), but you might prefer making smaller monthly payments.
There's also a schedule for vehicle loans and other debts such as credit card bills.
This does assume that you have a working knowledge of Excel- I'm afraid that I'm not that good at explaining how to drag cells around.
Anyways... I hope it helps you guys as much as it's helped me plan out my budgeting. :)
