If you want to see how they work, take a look at the above spreadsheet.

I'm not going into detail, but I'll give you the 2 tips that you'll need. One of the tricks to creating a chart like this in Excel is knowing what type of chart to use, and how to make it work for a variable length amortization table. My loan amortization schedule and mortgage calculator are much more useful for use in evaluating and tracking real loans and mortgages. This file is intended for educational purposes only.
