Once wildly expensive and inaccessible but to the very rich, computers today are one of the most ubiquitous technologies worldwide. In 1972, the most basic model of an HP 3000 sold for $95,000, the equivalent of slightly over half a million in today’s dollars. Today, a brand-new computer costs just a few hundred dollars and has capabilities that in 1972 were the realm of science fiction.

The advent of the personal computer is one of the most important technological developments of the last century. Personal computers became accessible to the public in the early 1970s, as technology improved to the point that the devices no longer needed to be the size of a car to function. Personal computers were an innovation in both size and cost, offering consumers a product that could fit within both a small room and the typical budget. Although personal computers in the 1970s were larger and costlier than they are today, they were a significant improvement over the other machines available at the time.

The early desktop computers that arrived in the late 70s and through the 80s provided one tiny fraction of the graphics, storage, and processing capabilities of the devices we have today — and at the several times the cost. However, for the time, these machines represented a massive improvement in the way we process data, conduct business, and interact with the world.

As the computer transitioned from technical marvel to household staple, a number of landmark devices that came on the market set the bar higher for the generation of PCs that would follow. These computers, which include 1977’s Apple II, 1980’s Commodore VIC-20, 1981’s IBM PC, were extremely popular at the time of their release. The Commodore 64 was released in 1982, and would eventually sell about 20 million units to become the best-selling personal computer of all time.

The 90s were also full of milestones in technology, in particular the widespread use of the Internet. Computers built to be easy and accessible, such as the iMac in 1998, provided American families with a portal to the world.

The last 15 years have had even more changes in the world of personal computing. The number of available devices rose, and the increasing quality of components allowed manufacturers to make smaller and lighter devices that could do much more.

In 2005, laptops outsold PCs in the United States for the first time. The iPhone’s introduction in 2007 marked the beginning of an era in which computing became truly mobile. Other handheld devices such as the iPad offered yet another option. In 2015, more tablets were sold than all laptops and desktop computers combined for the first time.

To estimate the cost of a computer in a given year, 24/7 Wall St. identified the price of specific computers representative of every year between 1971 to 2015. Computers were considered representative if it was released that year, and held an important place in the history of computing. A computer may be chosen as representative for a number of other reasons. A chosen computer may have been best-selling model of the year, or contain a significant technological development of that year, such as an innovation in processing power. Computers were only ever used for the year of their release, even if their sales or popularity reached a peak in a following year. The parameter of 1971 was set in accordance with the release of the first ever personal computer.

This is what a computer cost between 1971 and 2015.

1971
>Notable computer: Kenbak I
>Price tag: $750
>Inflation adjusted price: $4,410

Deemed to be the first personal computer by the Boston Computer Museum, the Kenbak I looks nothing like modern computers. The Kenback I was designed as an educational machine to teach students how to write programs.

1975
>Notable computer: IBM 5100 Portable Computer
>Price tag: $8,975
>Inflation adjusted price: $39,555

At about 50 pounds, IBM’s 5100 Portable Computer was hardly portable by today’s standards. A decade earlier, a computer with the same processing capacity would weigh about half a ton.

1976
>Notable computer: Apple I
>Price tag: $667
>Inflation adjusted price: $2,778

The Apple I was the first product sold by Apple. It was originally designed for computer hobbyists who could make use of its bare circuit board. After Steve Jobs added a keyboard and display to its design, the Apple I was sold as a consumer product for $666.66. It was replaced by the more user-friendly Apple II the following year.

1977
>Notable computer: Apple II
>Price tag: $1,298
>Inflation adjusted price: $5,079

In 1977, the world was introduced to a personal computer that dramatically improved on the Apple I. Notably, the Apple II provided the entire personal computer package. It was pre-assembled, rather than in a kit. It is considered by many the first widely successful PC.

1978
>Notable computer: IBM 5110
>Price tag: $9,875
>Inflation adjusted price: $35,912

The IBM 5110 was designed to be an affordable machine to assist businesses with accounting and reporting. Despite the company’s hopes, the computer never achieved mainstream success. Incidentally, 1978 was the year computers were first installed in the White House. Staffers in the president’s home were given access to Hewlett-Packard’s far more expensive HP 3000.

1979
>Notable computer: Heathkit H-89
>Price tag: $1,595
>Inflation adjusted price: $5,232

The machine was also the first computer to ever sell more than a million units.

1981
>Notable computer: IBM Personal Computer 5150
>Price tag: $1,565
>Inflation adjusted price: $4,100

The PC 5150 was IBM’s most successful attempt at a personal computer at the time and was used as the basis for most computers that followed. The basic unit sold for $1,565, and the full model for $3,000.

1982
>Notable computer: Commodore 64
>Price tag: $595
>Inflation adjusted price: $1,462

It may surprise some to learn that the best selling personal computer in history is not an Apple or an IBM, but rather a Commodore. The now-defunct Commodore International, which had also built the VIC-20, introduced the 64 in 1982, which was widely loved for its gameplay capability and state of the art sound chip. The Commodore 64 sold roughly 20 million units during its run.

1983
>Notable computer: Apple Lisa
>Price tag: $9,995
>Inflation adjusted price: $23,794

The Apple Lisa was one of the first commercially available personal computers with a graphical user interface. However, the Lisa’s high cost ultimately doomed its chances of success. The machine was inspired by the nearly decade old Xerox Alto, which also had a graphical user interface though was never made commercially available.

1984
>Notable computer: Apple Macintosh
>Price tag: $2,495
>Inflation adjusted price: $5,694

The Macintosh is considered to be the first commercially successful computer to have a graphical user interface. Users could navigate by clicking through images with a mouse as opposed to the text-based commands used in earlier computers.
