I have been using both the 12c Platinum (call it 12cP) and 12C for study and at work. I use the 12C gold more often than the 12cP.

My biggest disappointment with the 12cP is its relatively slow processing SPEED vis-a-vis the predecessor 12C and its competition (the HP10B, TIBA2plus).

The 12cP is notably slower than the 12C especially when performing Time Value of Money (TVM) calculations.

Running both HP12s side-by-side with the same data input, my 12cP has been consistently slower by 50% as compared to my 12C.

If possible, I would suggest that potential users and buyers try this data set on both the 12C and 12cP before buying. Clear register. Find [i] after input [PMT]=-1458;[FV]=0,[n]=84,[PV]=103600. The HP12C would take 20 seconds "running" while the HP12cP would take about 30 seconds to give the same answer [i]=0.4059!

This apparent lack of speed is difficult to accept for a supposedly latest financial calculator upgrade from any manufacturer! It is a bad joke, considering that my 12 years old HP10B could perform the same TVM calculation in just 2 to 3 seconds!

However,both HP12Cs are great value for money if the user consider the TOTAL solutions and free website support and training which is available from HP. In addition, there are lots of literature and solutions written by third party users over the still ongoing 20+ years production run of the 12C. IMHO,in addition to excellent user support, the PROGRAMMING capability of the HP12c is the other major face saving advantage which put both the 12Cs over its TI challengers for now.

The good people @ HP may like to know that 96% of my fellow students are now using their competitor's Texas Instrument TI-BAIIplus!

Many people wonder: Should I get the HP 12c Platinum or the old standby, the HP 12c gold. Personally, I'd recommend getting both. Like most things, each model has advantages and disadvantages, but both are still among the finest feats in engineering in terms of a calculator. Keep in mind there are two versions of the Platinum -- the original and the 2.0 version. The 2.0 version is much better, and you'll know you have it if it has backspace and undo [g] functions. It's finally a respectible "upgrade" to one of the best calculators ever made.

What about the 12c Platinum?


- Much, much faster than the gold. It crunches IRR calculations in a fraction of the time. You might even find yourself missing the "running" message that's so common with the gold HP 12c. You cannot overestimate the advantage of the increase in speed, especially with test taking.

- Backspace and undo key. Having a backspace key really is nice, especially if you work with many long numbers.

- More program memory. Unlike the gold, the Platinum can hold something like 999 lines of memory. The gold only holds 100 or so, which fills up pretty quickly. Some options pricing models, for instance, will consume all 100 lines.

- Color. Many younger people think the silver color looks "cooler" or more current. Personally, I like the gold -- looks retro or something. It's personal taste, though.


- Slightly slower "wake up" period. You have to hold the 'on' button about a half of a second longer for the Platinum calculator to turn on versus the gold. Not a big deal, but a little frustrating for gold users who have years of habit.

- Display font not quite as nice. The gold's display is really nice.

HP really dropped the ball on this one. The 12cp is poorly made and not worth the money. As was mentioned before, the TVM functions are slower than the 12c. One would think that one of the design benchmarks would be to at least out perform the 12c! There is also a bug in the programming side of the calculator, which if you want more detail, is defined at some calculator websites. I was duped into buying the 12cp and, upon opening the package, immediately noticed the poorer design. The numbers and functions on the keys are painted on instead of being molded into the plastic of the key. I already have a key that is scratched from accidentally dropping the calculator. Also, the "Enter" key has a bounce to it that gives a double click every time I use it. This may be particular to my 12cp, but it is incredibly annoying and the 12c, which I have had for years, works flawlessly. It may be slower, but stick with the "gold" standard and maybe buy an extra one in case HP discontinues it. I gave it one star because they require that something be selected.

guys - if you are still planning on taking the CFA (or even if you're not) using an HP 12C calculator, i emphatically recommend popping down to J&R (price match to wal-mart.com will save you $5) and buying the new HP 12C Platinum for $79.99. It is a zillion times faster (well, 6X) than the regular one but otherwise works almost exactly the samely. for example: i ran the following calculation simultaneously on the both and used identical button pushes to achieve them, but the platinum was incredibly faster:

time in seconds

enter cmd Gold Platinum

360 n instant instant

6.625 g i instant instant

740000 PV instant instant

0 FV instant instant

running PMT 1.8 0.5

0 i

running i 16.8 2.7

other differences:


faster (holy cow is it faster!!!!)

has backspace key (works okay, not super useful tho)

has undo command (this is real easy to use and comes in handy once in a while)

has algebraic entry mode (not just RPN) and parenthesis (both useless if you ask me)

has spot to scratch in your name on the back (cute)

comes with a nice hard leather protective holster (cheap quality though)


display doesn't blink with each key press to acknowledge entry - this stinks and is actually a very big deal!

screen doesn't look as nice (they used a standard calculator LCD instead of the awesome stylish one they used to use - actually the new one's screen looks terrible when you put it right next to the gold one - the gold had a GREAT screen and great font that was really easy to read and looked super classy. i will miss it very much.
