Something off?
Report an issueMore than 30 years ago we saw the birth of the most popular financial calculator ever created--you probably had one (and probably still do!).
Calculator12 puts a rock solid emulation of that calculator on your iPhone, iPod touch and iPad, whether you need it for school or are looking to retire old faithful. What you get is true (albeit non-programmable) emulation with 100% compatible operation keystroke for screentap and computational and operational reliability every bit as good as the original.
But wait, there's more! (sorry about that). Calculator12 is not stuck in the 80s. You have the option to work with cash flows in the cash flow diagram format, changing values or inserting/deleting cash flows with just a tap. Three independent cash flow scenarios can be evaluated side-by-side, and with capital multiplication you can evaluate an exit strategy for outside investors. Results can be emailed from Calculator12 so you don't have to redo things like an amortization schedule or comparative investment report at your lap or desktop.
And you can see what was once hidden... the contents of the financial registers or optionally the stack are always displayed. For me at least confirming the accuracy of my entries relieves a lot of anxiety and prevents confusion when the results don't stack up. It's not programmable, but advance payment leasing functions have been pre-programmed in as well as conversions to APR and Effective Rate to fill some of the gaps. And it is blisteringly fast--what used to take 30 seconds now is done almost before your finger leaves the touchscreen.
Calculator12 was the very first emulator of that physical machine on the App Store, v1.0 released July 30th of 2008, introducing features (now almost universally copied) that take advantage of the unique features of iOS to improve your ability to deal with financial problem solving. There are lots of emulators now, but only one that has moved out of the 80s. (this one!)

8 of 25I will be using this for my finance class this semester and it's cheaper than a real 12C!
I have been a long time user of the HP 12-c financial calculator. This application met and is now exceeding my expectations. The developer is regularly coming out with updates, making it better than the original. I have tested functions against my 12-c calculator and the application appears to give me the same results. Am very happy.
Why is it that every other upgrade changes it's ability to do a simple loan or savings interest calculation. Please fix..... I think a financial calculator should at least be able to do that. Is there a way to go back to the pre update version that could actually calculate????
some key functions show error messages. no support. it costs $20. I am ripped off my money. now I have to buy another. what is the point? this is the equivalent of stealing..... I think all positive reviews are fake. the calculator cannot perform simple operations such as find I when PV, FV and N are given. As well it does not find N. DISAPPOINTING.
Excellent port of my trusty 12C. I very much like your add of the register displays under the main display panel. Like some others, I am impressed how much extra speed you have been able to wring out of the old routines using the iPhone's much newer processor. I hereby offer a few suggestions for your update list: 1) Echoing others, key clicks are critical. 2) The yellow f and blue g key labels could be slightly dimmer in normal display mode, especially since you highlight them on pressing the function keys (a nice touch). This would be less distracting. 3) Similarly, the white key labels could be slightly dimmer, too (and/or the black background less dark). The contrast now between all labels and the keyboard background is so high that it will be tiring to look at for extended number crunching. 4) I know you are working from a photo of an actual 12C, but all the key labels and f and g labels could be crisper. Tighten them up with a pixel editor. No reason to be slavish to the past. 5) I would prefer the display panel numbers (results) to be slightly smaller, in favor of slightly larger register contents displays, but this is not a biggie. 6) I would find the original bond math functions useful. I would not miss the program functions at all. Some will disagree with me. 7) Would be nice to have the [f] prefix function, to temporarily display the panel number in floating precision, but no biggie, either. Well done, and heading toward a five star review with your updates. Am curious to see what new, soft functionality you decide to build in. Your calculator could end up putting my original out to pasture for good.
This is a very nice implemtation of our beloved 12c. I love all the extra functionality. It's a little hard for me to use though, because some of the keys aren't where I'm used to seeing them. On the iPad, I hate that the stock background flashes before switching to my chosen background. Is there any way to get rid of that? Great calculator though and I haven't noticed any other issues with it.
This is the best iPhone implementation of our favourite HP 12C calculator! Not only does it have all the features of the 12C, it also smartened it up with what a modern smartphone can offer with extra display info and conveniences. The pricing is also just right. Although I also have HP’s 15C port on my iPhone and use that for the various mundane calculations in a simplified portrait format, this one from Stone Meadow Development is my go-to for anything above that. No regret for the purchase from quite a while back and the support has been fantastic, now iOS7 updated. Can’t recommend enough!
The HP 12c is a standard - these folks kept the standard and improved it dramatically. HP simply recreated their calculator on an iPhone - didn't give any thought to improving it. In my mind, my "flagship" differentiator is the cash flow viewer/editor... if you've never tried it it's slick IMHO. It allows you to see your cash flow entries as a cash flow diagram, and edit them (including adding and deleting individual cash flows) using the visual format--with the HP you can only delete the last cash flow and to do so you have to change the value of the n-register and you can't add a cash flow in the middle of your series. If you messed up entering the cash flows, you have to start over from CFo. Emailing results, in particular amortization tables and calculations dealing with cash flows and one-tap access to the forum's FAQ page is very helpful - these guys did it right!!
