The present invention provides a method of providing a reusable calculation scale framework. The reusable framework may be used in an electronic commerce environment. Th e electronic commerce environment defines a calculation rule and a set of commerce object s. Typically, the commerce objects are line items in invoices, purchase orders or other commercial documents or records generated in connection with web-based transactions. The method comprises steps of providing a calculation scale look up interface, a range look up result interface, a multiplication product of the results returned by the two interfaces, an apportioned moneta ry value for each of the commerce objects. The method is particularly useful in implementations f or determining weighted shipping charges, discounts and taxes in various commercial environments. The environments may include a variety of calculation rules based on the circumstances in the commercial environment. The invention also provides a computer product for implementing the various methods. The computer product includes a recording medium such as a magnetic floppy disk, CD-ROM, hard drive or other suitable means. The products and methods a re particularly useful in association with web-based commercial software applications. The methods and products provide a calculation scale framework which may be reused to avoid programming changes despite frequent, and often significant, changes in commercial environments.
