Comprehensive Excel Evaluation Spreadsheet?

[Marty Uczen]

Not sure what forum this should be in. Please move if this is not the right forum.

I am looking for a spreadsheet that includes the following:

- Amortization Schedule tied to analysis sheet to separate interest expense from principal on an annual basis

- Income Tax rate input so I can analyze after tax cash flow results

Ultimately, I would like a detailed income sheet and cash flow statement to calculate ROI, Cash Return and to analyze hold or sell/reinvest scenarios based on the return on equity.

I looked through several spreadsheets under tools but could not find one that had enough elements to pull together. I know I am asking for a lot but even if I there were spreadsheets with a few elements each I could cobble together.
