Happy 40th Anniversary to the Iconic, Timeless HP 12C Financial Calculator! (2022)

Pictured above is the HP 12C Financial Programmable Calculator, available from the Hewlett-Packard website for $69.99. What makes this calculator totally unique among all consumer electronic products is that it was first introduced by HP 40 years ago at a retail price of $150 (more than $450 in today’s dollars) in 1981, and yet even today is considered to be a relevant, up-to-date, “state of the art” product for financial professionals, CPAs, financial analysts, mortgage brokers, real estate agents, investors, and finance professors. I have used HP-12C financial calculators on a daily basis since the 1980s and currently own five of them: two original 12C models, one 25th Anniversary models (released in 2006), and two “Platinum” HP 12C models (sells for $79.98 and has more processing power and storage space than the regular HP 12C, and also features both Reverse Polish Notation (RPN) and Algebraic entry modes – more on that difference below). Now that it’s 2021, and since I couldn’t find anybody else who has done so already, let me be among the first to say “Happy 40th Anniversary, HP 12C Financial Calculator.”

If you aren’t convinced that the HP-12C financial calculator is maybe the only consumer electronic product from 1981 that is still relevant and up-to-date after 35 years, browse a 1981 Radio Shack catalog here (check out the telephones, stereo equipment, reel-to-reel tape decks, cassette players, portable stereo systems, 8-track tape players, telephone answering machines, TV antennas, radios, calculators, “microcomputers,” typewriters, etc.) and see if you can find any other consumer electronic available in 1981 that is still considered relevant and up-to-date today! If you can find an example, I bet there won’t be very many!

To get an idea of how much consumer electronics have advanced in the last 40 years in both quality improvements and price declines, the 1981 Radio Shack catalog features the “top-of-the-line” microcomputer for an “unbelievably low price” of $3,450 and a dot-matrix printer for $1,960 on p. 172, see graphic below. In today’s dollars, the computer would cost $10,500 and the printer would cost $6,000.

Here are some related links about the HP-12C Financial Calculator:

1. Almost fifteen years ago in the very early days of CD, I wrote a post about the 25th anniversary of the HP-12C in 2006, here’s an excerpt of that post:

The goal of developing the HP-12C was to have a sophisticated programmable financial calculator, that would be small enough to fit in a shirt pocket, would have long battery life and would meet the HP “drop test” – the ability to withstand a fall from a desktop onto a concrete floor. HP worked with a team of researchers who had Ph.Ds in numerical analysis, mathematics, electrical engineering, and computer science to develop the 12C.

The decision was made, for the ultimate mathematical and computational efficiency, to use RPN (Reverse Polish Notation) for data entry (with no need for Equal key on the calculator), instead of the traditional algebraic entry (which uses an Equal key on a traditional calculator). For example, instead of 2 + 2 = 4 (algebraic entry), RPN entry would be: 2 ENTER KEY 2 + (the mathematical operation comes last). Although mathematicians and engineers were comfortable with RPN, HP was concerned that finance professionals would have trouble accepting RPN, but the calculator became a huge success among the finance crowd, and is still used widely today.

2. Also in 2006, HP had a backgrounder on the HP-12C titled “Some things at CES never go out of style – HP’s 12C hits 25-year mark in 2006,” here’s the opening:

The first business “personal computer” was unveiled, Pac-Man was the blockbuster video game, and Chariots of Fire was a box office hit when HP introduced a $150 pocket-sized device that revolutionized financial calculations for people on the move. The big hits of 1981 are now history, but the HP 12C financial calculator is still going strong. Instantly recognized for its unique horizontal layout, the HP 12C financial calculator has sold in the millions to investors, real estate professionals, accountants, loan officers, business students and teachers.

The HP 12C financial calculator, the product of a vision by HP’s labs and an Iowa farm boy with a love for physics, is an iconic consumer electronics product that is still sold virtually unchanged under its original name and model number 25 years after it was introduced. The HP 12C that’s sold today acts and looks just like it did when it was first snapped up by thousands of financial and real estate students and professionals at its worldwide debut. Few other products of industrial design have achieved such a classic distinction.

3. In 2003, HP introduced the HP 12C Platinum that allows the user to select either entry mode: RPN or Algebraic. Although once you get comfortable with RPN, I can guarantee that you will NEVER want to go back to traditional Algebraic entry, it is TOO slow and inefficient. Here’s a comparison of the HP 12C vs. the HP 12C Platinum models (e.g., HP 12C Platinum has “Undo” and “Backspace” buttons which the HP 12C lacks).

4. Here’s one explanation of why RPN is more efficient than the Algebraic entry mode:

RPN is an extremely powerful system and when mastered can save you keystrokes and thus saving you time. This would mean that you would not need to use parenthesis in your calculations. The RPN mode also shows you the intermediary results in your calculations, which makes complex calculations easier to keep track of.

5. Here’s the Wikipedia entry for the HP-12C, which is described as “HP’s longest and best-selling product, in continual production since its introduction in 1981.”

6. In 2011, CNet wrote about the 30th anniversary of the HP 12C in an article titled “HP 12C calculator: Still up-to-date after 30 years,” here’s a slice:

You probably change your computer every couple of years and update your phone based on Apple’s release cycles. But chances are that inside your briefcase or in your desk drawer, there’s a gadget that hasn’t been changed for decades. It still works well, and you like it just the way it is.

The device in question is the HP 12C calculator, first launched exactly 30 years ago today, on September 1, 1981. Ever since, without much fanfare, it’s been a quietly vital tool in finance, business, and academia. According to HP, the 12C is still one of only two standard calculators permitted for use during financial professional certification exams. This is because when it was released, the calculator offered more-accurate computations than the federal standard. It also features an unmatched keypad layout that provided unprecedented ease of use. The device itself is compact enough to fit in a pants pocket.

7. Also in 2011, the Wall Street Journal reported on the HP 12C’s 30th anniversary in the article “Wall Street’s Cult Calculator Turns 30,” here’s an excerpt:

Thirty years after the launch of the 12c, it’s still commonplace for financial analysts filing into a conference room to set down their calculators next to their papers and cellphones.

Indeed, the 12c, which costs $70 on H-P’s website, is H-P’s best-selling calculator of all time, though the company won’t reveal how many units it has sold over the years. (A standard calculator costs about $10.) Its chief competitor is Texas Instruments’ $28 BA II Plus, which is the only other calculator test-takers are permitted to use on the official CFA exam.

The 12c is slim, black and gold, and rectangular, just over five inches wide by three inches high. It runs on an unconventional operating system called “Reverse Polish Notation,” which eschews parentheses and equal signs in an effort to run long calculations more efficiently.

That may be one reason users are reluctant to switch. “I’ve become so addicted to it that I am unable to use the iPhone calculator correctly,” says John Lynch, chief equity strategist at Wells Fargo Funds Management Group in Charlotte, N.C.

The system tends to render the calculator mystifying to the novice user. Senior portfolio managers, who use it to calculate bond yields, rates of return and present value, among other things, say they enjoy watching their younger colleagues struggle to master its quirks.

“One benefit is that when I leave it on a conference table here at our offices, none of the young analysts know how to use it,” says Christopher Wolf, co-chief investment officer at Preservation Trust Advisors LLC, a mutual-fund firm in San Francisco, who bought his 12c in the early 1980s. “It’s like an early fingerprint-recognition system.”

MP: The Schumpeterian forces of creative destruction have made almost all consumer electronic products from the early 1980s obsolete today, having been replaced by products that are better, faster, more durable, and cheaper. But possibly more than any other consumer product that was available in 1981 (think cars, phones, cameras, TVs, stereo equipment, computers, etc.) the iconic, timeless HP 12C Financial Calculator stands alone as maybe the only electronic product that has survived the last 40 years of tsunami-level tidal waves of “Hurricane Joseph’s” creative destruction that has destroyed and replaced almost all other 1981-era consumer products!
