Texas Instruments Business Analyst

Though originally designed specifically for financial use, current models also include basic scientific calculator and statistics functions.

The BA series competes directly with other mid- to high-end financial calculators, particularly the HP-12C and other models from TI competitor Hewlett-Packard.

[citation needed] The BA II Plus Professional is an upgrade to the base model introduced in 2004, including several additional worksheet functions such as net future value and modified internal rate of return.

Several companies, most notably Texas Instruments itself, have released emulators of the BA II Plus for various mobile operating systems.

In addition, Stokes Publishing formerly sold The Educator Business, a calculator designed for use on overhead projectors that emulated the BA II Plus.
