Perhaps the only difference is that the Texas Instruments BA II Plus Professional has a sturdier build and a stronger keypad.Īdditionally, there are a few more minute upgrades to the Texas Instruments BA II Plus Professional version.
Though it contained a full set of TVM functions, it lacked the advanced scientific calculator functions of later models of the BA II. The BA-35 was targeted at students studying finance and was available from 1985 to the late 2000s. The short-lived TI-10 Profit Guide had similar functions in a pocket calculator size. Early models included a built-in clock module, which was removed for the 1998 revision. In addition, Stokes Publishing formerly sold The Educator Business, a calculator designed for use on overhead projectors that emulated the BA II Plus.Īn app on the Apple App Store is also available by Texas Instruments mirroring the Calculators design and functionality.įrom 1986 to sometime after 2010, TI produced the BA-20 (also known outside North America as the TI-620), which was a basic desktop calculator with the addition of dedicated cost, margin, and sell calculation buttons. Several companies, most notably Texas Instruments itself, have released emulators of the BA II Plus for various mobile operating systems.
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. It has not been made available in a solar-powered model. The 2014 revision includes larger display numbers, but the computation functions remain the same as previous models. It is permitted on several professional exams, including the international Chartered Financial Analyst exam. It has been available in three case designs, based respectively on 1989's TI-68, 1999's TI-30X IIS, and the 2013 revision of the TI-30Xa. It provides basic scientific calculator functionality alongside its financial functions, and provides most of its financial functions in the form of worksheets, where values are input as variables in a table when a computation is requested, the calculator plugs the values from the worksheet into the appropriate internal expression and returns the requested result. The BA II Plus is the main financial calculator sold by Texas Instruments as of 2015. Texas Instruments BA II Plus Professional
