The calculator included functions for solving financial calculations like time value of money, amortizing, interest rate conversion and cash flow. Business functionalities included percentage change, markup, currency exchange and unit conversions. It also had math capabilities such as trigonometry and graphing.

The calculator could also print via a built-in infrared transmitter to a supported infrared printer such as the HP 82240A or HP 82240B; which allowed you to print out the generated graphs.
