Technical Details - The HP-12C is HP's longest and best-selling product, in continual production since its introduction in 1981. Due to its simple operation for key financial calculations, the calculator long ago became the de facto standard among financial professionals.[1] Its popularity has endured despite the fact that even a relatively 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

    I have had one of these calculators for 48 years and it continues to perform perfectly. I have only changed the batteries once. I use it to perform quick or complicated calculation when I don't want to take the time to boot up my laptop.
