The HP-12C is HP's longest and best-selling product, in continual production since its introduction in 1981.^[1] Due to its simple operation for key financial calculations, the calculator long ago became the de facto standard among financial professionals – for example, most investment banks issue HP-12Cs to the members of each incoming class of its investment banking analysts and associates. Its popularity has endured despite the fact that even a simple, but iterative, process such as amortizing the interest over the life of a loan—a calculation which modern spreadsheets can complete almost instantly—can take over a minute with the HP-12C. The 1977 October edition of the HP Journal contains an article by Roy Martin, the inventor of the simple method of operation used in HP financial calculators, which describes, in detail, the mathematics and functionality built by Prof William Kahan (from UC Berkeley) and Roy Martin that is still in use today.

Later HP financial calculators are many times as fast with more functions, but none has been as successful. The HP-12C's programming mode is very intuitive and works like a macro operation on a computer. Basically, the keys one would press in the calculating mode to arrive at a solution are entered in the programming mode along with logical operators (if, and, etc.) applicable to the solution. After the programming is complete, the macro will run in computation mode to save the user steps and improve accuracy. There are 99 lines of programmable memory on the HP-12C, and 400 lines on the HP-12C Platinum.

The HP-12C is one of only four calculators permissible in the Chartered Financial Analyst exams, the others being its sister, the HP-12C Platinum, and the Texas Instruments BA II Plus and BA II Plus Professional.

This unit is USED and it is in good condition

New, true leather case for HP Pioneer calculators, including HP17bII, HP10b, HP14b, HP27s, HP22s, HP32s, HP42s calculators. Dark brown color like the original.

The original Pioneer calculators had a vinyl case that resisted quite well the passage of time - and that was designed to be kept in the jacket pocket. It also had the knitting "inwards" so that it occupied the less possible space for a given volume.

Later versions (HP17bII+) have been made in false leather (called PE), which has a very low resistence to external scratches. There are several types but all of them in my possession have now a very bad aspect after few years. For the current HP17bII+, the case is not even suited for jacket pocket, since it has very square corners.

We have decided to create real leather cases that stand the passage of time, made with the same material that pocked cardholders and money holders are made. We have selected a manufacturer in Ubrique (Spain), famous for this kind of work. We sent to them the originals and the calculators that go with it, so that the case you have with you is not something similar that fits well - it has been expressly designed for your calculator

Please take a look also to the leather cases for Voyager (HP12c y HP15c).
