This is a sample worksheet, it is what some call a template.  It is setup
1,4,2R
to show you how you can use "TurboCALC(tm)" to do a family budget.
1,6,2R
To use the template you just put numbers in for each expense catagory and
1,7,2R
put in the amount for the income figure at the bottom.  The worksheet will
1,8,2R
calculate the total expenses and the amount that you can save or must take
1,9,2R
from savings.
1,11,2R
"TurboCALC(tm)" can forward reference cells and come up with the correct
1,12,2R
answer, even if the forward cell comtains a formula!  An example of this
1,13,2R
is shown after the "Budget" below.
1,15,2R
At the end of this worksheet is a sample of the technique used for the
1,16,2R
Internal Rate of Return function.  While this function is very nice, it
1,17,2R
does take time to calculate.
