for the most current version of Stu Miller's spine calcuator, visit

This calculator is free and requires a spreadsheet program to run. If you don't have a spreadsheet program such as Excel. Sun Microsystems offers OpenOffice which is an excellent substitute for MS Office. There's a link to OpenOffice on Stu's website.
