HP 30b Business Professional


The HP 30b is their mid-level RPN financial calculator. It is aimed primarily at professionals in real estate, finance, accounting, and business.

It is the best bargain in the premium financial calculator market, with some advanced features found on no other financial calculators, being comparable to more expensive models.

Note: For international deliveries, I can ship it in an envelope instead of a box, reducing the shipping fee to US$15 (instead of $27+). However, the calculator is not quite as well protected in an envelope. Please email me for details.
