About Us


Engineered Finance is the creation of a couple of engineers who fill their downtime with complicated formulas and a strong desire to see all numbers in small, adjustable boxes on a computer screen. Since no financial tool would be complete without a disclaimer … here you go:

The spreadsheets promoted and sold on this site are intended for educational and entertainment purposes only. While they have been tested in a number of scenarios, it would be impossible to test them for every possible situation.

Many, if not all, of our spreadsheets involve tax calculations based on US Tax Code. US taxes are a complex labyrinth of tax laws (defined in Title 26 of the United States Code), Treasury Regulations (found in Title 26 of the Code of Federal Regulations), and official tax guidance (including revenue rulings, revenue procedures, notices, and announcements).

Tax laws are constantly changing and it would be impossible to account for every possible tax situation in these kinds of products. Instead, we have tried to cover the most common situations that we think would have the broadest applicability.

While every effort has been made to ensure that any calculations performed in these spreadsheets reflect current basic tax laws, these are not intended to be, nor should they be viewed as tax tools.

We do not provide financial or tax advice.
