Spreadsheets & Calculators

Calculators, spreadsheets and tables (plus a few articles not converted to web pages yet.)  

Some of these pages are in  in PDF format which requires Adobe Reader to open.
If you don't have Adobe Reader, you can download it here.

The calculators and balancing spreadsheets are in Microsoft Excel.  Most can be opened with Numbers if you have a Mac or they can be opened with Calc from Open Office, an open source office suite.

If you find the tools on this website helpful, please consider a small contribution to acknowledge the time and effort it
takes to develop and maintain them.  Thank you.
