The BA II Plus, Without the Plastic
A free browser-based emulator of the TI BA II Plus, with dedicated finance calculators for TVM, NPV, IRR, bonds, amortization, statistics, and more.
Field notes
The site offers two interfaces for the same finance workflow: a key-by-key emulator and separate forms that expose substituted formulas, schedules, or charts. Its scope is unusually concrete, covering nine worksheet areas and 44 advertised keys, with details such as up to 24 uneven cash-flow groups for NPV and four regression models for statistics. The page states that readings display to six decimal places and that the emulator is intended to match exam-room behavior, though those claims are not independently testable from the extract.
