HP 12C Platinum Calculator is a finance calculator for people who still want the old HP style of keystroke-driven number work. By our assessment, the draw is the dense, efficient key layout and the long reputation of the 12C line, which makes it a familiar tool for financial calculations. The downside is that this kind of calculator asks for memory and practice, and it is not friendly to someone who wants a modern touchscreen flow. In use it feels precise and compact, but also a little stern: the value is in speed once the logic is learned. Compared with phone calculator apps, it is more specialised and less casual. The 12 in the name is part of the product identity, and that old-school identity is really the point.
