Customer ratings and reviews for HP 12C Financial Programmable Calculator

Rated 1 out of 5 by Flawed keyboard Sticky keys! To Temporarily fix it Reset the device by powering on while holding the minus sign. Make sure to hold the minus key for at least 10 seconds after releasing the ON button or else the sticky key syndrome returns. I wish I realized the sticky key problem sooner so I could have returned it during the one year warranty period. I also that wish they still made the scientific version that let's you delete one digit at a time instead of clearing x entirely. My 30+ year old 10c and 11c scientific calculators are FAR SUPERIOR made in USA products. They operate perfectly still to this very day. The new 12c financial calculator is completely unreliable because of the sticky key problem. For example, enter 1 2 3 then look at the screen it will indicate 112233.. BEWARE!!! January 17, 2014
Rated 1 out of 5 by miss calculation I am in real estate and use hp-12c to calculate mortgages and other financial calculation for clients and am surprised that I have not been sued yet. THIS CALCULATOR GIVES OUT WRONG ANSWERS, FOR EXAMPLE $200,000.00 MORTGAGE AT 5% OVER 30 YEARS THE CALCULATOR'S ANSWER IS $1,069.19, BUT THE CORRECT ANSWER IS $1,073.68 OR 300,000.00 AT 5.875% OVER 15 YEARS THE CALCULATOR ANSWER 2,499.12 AND THE CORRECT ANSWER IS 2,511.36. I own 2 HP-12c and they both give out the wrong answer. I figured this out when I bought my own house and noticed a big difference in my actual payment with hp-12c's number and ran the numbers in the MS-Excel. Excel's number match my actual mortgage payment. Am I not using my HP correctly or HP is that careless? September 1, 2013
Rated 1 out of 5 by The display is bad In natural light the display is difficult to read. Numbers appear where they should not and the comma shows through the period. It's blurry. August 11, 2013
Rated 4 out of 5 by 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. July 14, 2013
Rated 5 out of 5 by HP 12C I have used the HP 12C since the mid 1980s and prefer the 12c over other calculators. My first 12c worked for more than 20 years before being damaged and replaced. The 12c Platinum does not come close to the original as since 2009, I have had to replace three (3) of them that became unreliable. Of course, I am going to buy another HP 12C, but hope to get more than two years use from it. It is still the best. June 28, 2013
Rated 5 out of 5 by Still the best one out there. I started using the 12C in 1974 while working for a Big-8 Accounting firm. I still use one today and just purchased my 4th one. They last a long time. I even have a 12C app on my iPhone. April 17, 2013
