HP 12C Financial Calculator - Over 120 Functions: TVM, NPV, IRR, Amortization, Bond Calculator, Programmable Keys - RPN Desktop Calculator for Finance, Accounting, Real Estate - Case + Cloth

The HP12C is legendary for a reason. It remains the gold standard financial calculator for anyone wishing to learn how to use it. I can't think of many other products that have remained unchanged after 36 years of continuous production. In a moment of weakness some years ago I purchased the 12C Platinum. Never again, I quickly swapped back to the 12C this purchase replaced (and only because my bag was stolen on a train just before Christmas). The 12C is not just for oldies on a nostalgia trip, learning/using RPN and manipulating the stack is a productive mental work out in its own right. I think HP have addressed the quality issues that plagued some machines a few years ago. Mine has a solid feel to it and the keys have that positive 'i've pushed it' feed back sensation. The enter key works wherever on the key it is pushed. Personally I find the display easier to read than the 12C Platinum, but this may not be the case for everyone. From experience I know the 12C has a tremendously long battery life measured in years (between 3 and 5 according to use) augmented by a built in turn off function after around ten minutes of inactivity. The landscape orientation of the keyboard ensures much greater stability when holding to use versus the all but ubiquitous portrait format style of other calculators. This feature greatly reduces the risk of keystroke error when the machine is not being used while placed on a desk top surface for example. The housing or body of the HP12C has an inherent slope as it is thicker at the top than at the bottom. This makes the LCD display clearer and crisper to read. I found the slightly sepia LCD display background deals with office lighting glare better than the blue/grey backgrounds normally found on other calculators and also HP's 12C Platinum. It probably sounds a bit geeky to bang on about a calculator but if you do have to use one, you owe it to yourself to own one that at the very least you can enjoy at the same time. HP12C £49.99 - the look of confusion on a colleagues face "just borrowing your calculator err where's the = button, umm how does this work" - PRICELESS.

It is possibly the most beautiful calculator I ever have. It is such a pleasure to use it, sturdy, quality calculator. I love it.

THANK YOU!

I have been an owner of the HP 12c for almost 20 years now. The price seems high compared with the state of the art graphics calculators available and much of the financial functionality is surpassed by spreadsheet applications. However, as a ready and portable cross check it still works for me. This is a premium product at a premium price and truly classic piece of kit. I wouldn't be without one.

Do not buy this calculator! I have an HP12C that I bought many years ago (20+) which still works well to this day. However, I saw the new HP12C and thought, mainly for aesthetic reasons, that I would like a shiny new one (the old one is a bit grimy). I also bought one for my son so he could learn reverse Polish notation. To make the long story short, right from the beginning I had trouble keying in the numbers and functions; the keys were very stiff. I thought I just had to get more used to pressing harder on the keys (my old HP12C needs only a very light touch). However, even when I pressed each key diligently hard it often didn't record, for example, the decimal place. After being driven crazy by that problem, the "err" message started appearing requiring resets. Interestingly, my original HP12C has Brazil etched on the back (so I'm assuming that's where it was made) while the new one is made in China. Anyway, I finally gave up and asked for a refund from Science Studio who curtly responded that I was past the return period (I bought it 6 months ago). What ever happened to the product warranty?

I have been using the HP 12C for over 20 years, and its enduring quality is absolutely legendary—my original units are still working perfectly today. This calculator is a durable, reliable workhorse that covers all the critical functions needed for finance: Time Value of Money (TVM), NPV, IRR, Amortization, and Bond Calculations. Comparing it to modern devices, it's interesting to note how much faster technology has become. On older HP 12C models, running complex calculations like the Internal Rate of Return (IRR) would often display the "running" indicator for a noticeable period. The newer calculators are so incredibly fast that this indicator no longer appears, completing the task almost instantaneously—a small detail that highlights the HP 12C's incredible tenure in the market. The most important thing to note before purchasing is the requirement to use Reverse Polish Notation (RPN). This is a different input method than the standard algebraic method you might be used to. Instead of typing "2 + 2 =", you input the numbers first and then the operation: "2 [ENTER] 2 [+]." There is a learning curve, but once mastered, RPN is far more efficient and reduces the chance of input errors. It’s what makes the 12C a favorite among financial professionals. This is a fantastic, indispensable tool that I highly recommend for anyone serious about personal finance or real estate.

Produto de ajuda do dia a dia. Material de excelente qualidade.

計算機としての機能は十分であるものの、最近、液晶表示の右から４桁目の液晶の8本のバーのうち、2本が表示されなくなった。落下等の衝撃を与えたことはないので、単純な劣化と考えられるが、部品の耐久性に問題がある。

Gostei do produto

llegó a tiempo, bien empacada, sin ningún rasguño, funcionando bien, baterías en buen estado; en resumen tal y como la esperaba, igual a la que estuve utilizando con mucho éxito y por bastante tiempo hace mas de 40 años y que solo le tuve que cambiar las baterías después de 10 años de uso continuo, la que de no haberla extraviado aun la tendría. EXCELENTE PRODUCTO.
