Hewlett-Packard HWP-12C Financial Calculator is rated 4.0 out of 5 by 56.
Rated 2 out of 5 by from shocked at poor quality I am a HP fan, with HP laptop and desktops, and have used an HP 12C for more than two decades. I lost my original HP12C less than a year ago and had to replace it with another HP 12C, but the new one's screen goes blank unexpectedly when imputing numbers and prints error messages when there was no error and does this so often now that it must be replaced in less than a years ownership. Unclear why HP lowered the build quality on the product that made me an HP repeat customer. I would gladly pay more for better quality.

Rated 5 out of 5 by from HP-12 I bought one of the first HP-12's out (I think it was 1978 & cost $119.95). I still use it today as I have every day since then. I have been a real estate broker, appraiser, & mortgage auditor. I have even taught classes in the use of the HP-12. The use has been terrific ! I have a couple of programmed functions I use all the time. The numbers have worn off the back; HP has replaced the pad several times, but the calculator never fails. It is impossible to outdo this unit for the money. Howelse could it still be in production this long?

Rated 1 out of 5 by from Used to be a great product Am on my 3rd one in 30 years. First 2 were great. 3rd one didn't last a year before the display got messed up. only some of the numbers display properly. Not the batteries. The device works but you can't read the numbers in the display very well. This last one barely lasted a year. Know they don't make stuff like they used to but this is rediculus considering what I paid for it. Is there any way to shake the LCD display so that it is legible again???

Rated 5 out of 5 by from Calculation Corrections I've used this product for almost 20 years for financial and accounting applications and it remains as reliable as ever. For those who referenced incorrect mortgage calculations, you have your settings programmed to calculate at the 'Beginning' of the monthly billing cycle, rather than the 'End'. To change, simply press the blue 'G' key and then the #8 key (end). In your scenario, the $200,000 mortgage at 5% interest for 30 years will result in $1,069.12 if you have it set to calculate at the Beginning cycle or will result in $1,073.68 if set to calculate at the 'End' cycle. You can toggle between Beginning and End cycles by pressing the blue 'G' key then pressing 7 (for Beginning) or 8 (for Ending).

Rated 4 out of 5 by from Fast 12C, flawed keyboards from CY factory The HP 12C, now in "+" form 150x as fast as original HP12C. The HP 12C remains the icon of financial mastery even today, and the lightening fast speed is a delight. Production runs from the Inventec CY factory (with the large % sign) can have unresponsive or sticky keys, though. Mine repeats numbers. I have used HP 12C's daily since the USA 1982 model. Other manufacturers may have calculators that run PV's, but only HP made a real-world financial calculator.

Rated 4 out of 5 by from Great tool, but fix the buttons I've been using a 12C for 25 years - its a great tool. When sadly mine went missing (this one after at least 15 years), I was pleased to see it is still available and immediately ordered one. It is in all respects the same calculator except for the feel of the buttons. I know it may seem fussy, but these buttons have a cheap, tinny, hollow feel to them when pressing - not nice. The previous model, by contrast, had a very solid feel.
