  • A financial workhorse in the palm of your hand
    Verified BuyerReviewed by ncmntnman - November 12, 2016

    I don't recollect when I bought my first HP12C; (the one I am reviewing is a replacement for one that I lost), but it must be about 25 years ago because I was using it in a job in the finance business. Frankly, it can do more types of calculations than most professionals in finance will ever need--discounted cash flows, lease vs buy, mortgage amortizatoins with and without balloon payments and on and on, all at a very reasonable price, about the size of a deck of cards and possessing a responsive keypad, great battery life, etc. etc. in addition to being fully programmable for those who wish to design their own computer-in-a-pocket; a great tool

  • Best Financial calculator ever!
    Verified BuyerReviewed by Nate - November 3, 2015

    After using an HP 12C financial calculator for over 30 yrs, I bought an HP 10 to save money (half the price of the 12C). Cumbersome to use, I returned it the next day and purchased another 12C. It doesn't get easier to use than the 12C as long is you can get comfortable with the RPC (Reverse Polish Calc) keystroke sequence --> 12x2=24 --> is 12 ENTER, 2 x. The new 12C is a 1000x faster than the 25 yr old 12C I had. Try amortizing 10 yrs into a 25 yr mortgage to calculate interest paid, principle paid, and remaining balance and the answer takes less than a second. On my old 12C it would take 30 seconds! Gotta love the new chips!

  • Excellent financial calculator
    Verified BuyerReviewed by Raul - July 26, 2017

    As a longtime financial advisor, I used the HP12c Financial Calculator for nearly 30 years. It served me well, and helped me greatly in my work. Now retired, I took a real estate investment class with my wife.. The instructor recommended the HP 10bII+ calculator to the class. I bought 2 of these calculators for class use, and was amazed at how easy it was to learn how to use. It is far more intuitive to use than the 12c. My wife caught on how to use it quickly, and has become quite skilled at it. I had to unlearn a few things, but once I did, I now prefer using the HP 10bII+ financial calculator.
