10 Most Expensive Calculators In The World

Although calculators are the cheapest of all educational gadgets, occasionally you may come across a model with an exorbitant price tag. Fortunately, the latest scientific and graphing calculators are less expensive and loaded with more features than the early calculators that were priced more than $1000 when they were first launched. Most of these expensive calculators are rarely available nowadays, and hence are popular collectors’ items.

10 Most Expensive Calculators In The World



From the simple to the most complex, these calculators are capable of handling all types of calculations. The prices of the most expensive calculators nowadays are rarely above $200. Given below is a list of the most expensive calculators in the world.

Grillet Portable Calculator – $155,000

The most expensive calculator in the world is a 17th century vintage – the world’s first portable calculator. The calculating device, measuring 32cm x 15cm, made out of wood, was created by a Parisian named Rene Grillet de Roven in 1763. Designed according to the Napier’s logarithm, the calculator is one of the four historic pocket-sized mechanical calculators that exist till date.

Of the four surviving 17th century wooden calculators, one is in the possession of IBM, New York, and two are on display in an industrial design museum in Paris. The fourth was auctioned at the Christie’s auction house, where it was bought by a collector for $155,000.

Hewlett-Packard 9100A – $4900

The first calculator developed by Hewlett-Packard (HP) was a desktop calculator. Although HP considered it as the first example of a HP personal computer, the company preferred calling it a desktop calculator to increase its acceptability. When the programmable calculator was first launched by HP in 1968, it was priced at around $4900.

The price of a desktop calculator at that time was more than the price of a car that would cost between $2000 and $3000. HP 9100A was one of the best quality early scientific calculators capable of solving a wide range of engineering and scientific problems.

Wolfram Mathematica 9 – $2500

Although touted to be the world’s most expensive calculator, Mathematica is not a standalone calculator. It is a computational software program that can be downloaded and used as a virtual calculator. The standard version of the latest edition of Mathematica is priced at $2,495 and the Enterprise edition costs $6,995. The first version of Mathematica was released by Wolfram Research in 1988. Since then millions of users from around the world have been using it for solving their mathematical, engineering and scientific calculations.

Mathematica is considered more powerful than the best quality standalone graphing calculators. The latest version of Wolfram Mathematica features powerful computation tools that can be used for processing data in almost every area of statistics and data analysis, image processing and analysis, design analysis, financial engineering, GPU programming, geographical information system, computational biology, parallel computing, social network analysis and more.

    That first image of a “calculator” would cost about $250,000 because the image is actually an Enigma machine from WWII.
