I have an Excel worksheet in which I keep track of my expenditures by categories. I could rearrange my columns as follows:

Column A = Monthly income

Column B = What's left after subtracting (in other columns) total expenditures from total income.

Column C = Mortgage expenditure each month

Column D = Life insurance expenditure each month

Now you figure out the type of spreadsheet you can put together and what you would put in the various columns. If you need help using Excel or any other similar program, simply press the F1 key for the Help section.
