As financial calculators go, this is a very good one. While the HP 12C is a legendary financial calculator, I'd put this one up as being at least as useful as the 12C. Like the 12C it is programmable though with more powerful programming options, it has a solve function and black shoales function that the HP 12C lacks, can be used in either algebraic or RPN mode, and has all the traditional financial functions and a bit more. The keys are solid in the traditional HP shape. The one thing that feels a bit cheap on this caclulator is that the black functions listed above keys is not printed on the calculator. Instead, a thin clear plastic overlay is applied for those. Overall a great financial calculator that was unfortunately overlooked by many finance professionals and collectors. The seller shipped the item promptly and it was well packaged.Read full review

The latest offerings of scientific calculators leave a lot to be desired. The HP33s and HP35s have keyboard problems and bugs galore with no fixes in sight. Furthermore, these two calculators have no provision to update their firmware. Enter the HP30b. This one is capable of having its firmware updated and the keyboard is nearly identical to the discontinued HP32sii and HP42s. Some very clever people cooked up a new firmware dubbed the WP34s and printed overlay stickers. Those will turn this business calculator into a very capable RPN scientific calculator. It doesn't have much memory, nor is the LCD very good compared to what's possible, but you work with what you have. Do a Google search for WP34s and you'll see how fun and easy it is to modify the HP30b.
This is one of the finest HP Calculators ever! As always, great products are no longer made. This is definably a "They don't make them like this anymore" product. With a two line alpha numeric twelve digit display, it has the ability to input data via Reverse Polish Notation, Algebraic and normal Chain algebraic methods. It is one of the fastest calculators available. Running in a native ARM code while many other operate their software by emulation. The 30b is also acclaimed by users for its improved rotate-and-click keys. HP calculator enthusiasts has produced a firmware for converting the 30b into a programmable scientific calculator.

I should emphasize that I have not used this calculator's financial functions at all. Keep that in mind through the review. I bought two of these calculators to convert them into WP 34S and WP 31S scientific calculators. I used one for a week before I converted it. The keyboard is excellent, using hinged, hard plastic keys for a noticeable tactile response and no key wobble. The display is split between a dot matrix section which displays the action performed, and a standard seven-segment section that displays numbers, primarily. Probably my favorite feature of this calculator aside from RPN entry is the trig functions and "Math" menu. Other than the very similar HP20b, I have not seen a financial calc that can operate as an entry level scientific. The only real bad part about this calculator is they stopped making it. One of the two calculators I received had two keys that required some time and manipulation to free up a bit. They had a dull action at first. I don't know if it was a quality control issue or a result of how it was stored or shipped, so I'm not taking any stars away for it. They have data connection ports for updating and replacing firmware, which is how they can be converted to other calculators. Research the WP 34S project if you want to know more.Read full review
Unfortunately, I have to report that this calculator and the predecessor, the HP 20b have a bug. The depreciation schedules give incorrect results. If partial year beginning months are used the results will be inaccurate and not even sum to the value of the asset. Additionally the RBV/ RDV will be off as well. These units also calculate incorrectly when using DBXover. They will calculate the initial accelerated correctly, but when making the change to straight line, the depreciation numbers are off. Perhaps the worst aspect of this: the depreciation does not sum to the value of the asset. Anyone relying on these numbers each year is losing money. HP should be ashamed. Bad numbers for TWO generations of calculators? It is unfortunate because this calculator is excellent in so many other ways. For the sake of credibility you should know that I am not a novice. I verified these numbers against other HP calculators, and other manufacturers. (I own every current model of financial calculator). I'm a financial consultant. This problem has also been reported by other users on HP forums. If you want a menu-driven calculator without any bugs I recommend the TI BAII Pro (which the HP 30B is designed upon) It has most of the functions of the HP 30B. The BA II PRO and the HP 12C are the only calculators accepted for the CFA exam.Read full review
