How much did the first commercial mobile phone cost?

How to get close to this number

Price it as new technology. A first-generation consumer device with no competition and tiny production volumes is priced for people who need it professionally rather than for households — which puts it in the thousands of dollars, not the hundreds.

The inflation adjustment in the explanation is the part that makes it land: roughly twelve thousand dollars in today's money. Any historical price is meaningless without conversion, and a four-figure price from the 1980s is a five-figure price now. Always adjust before judging whether something was expensive.

The specifications are what convey how early it was: eight hundred grams, thirty stored numbers, thirty minutes of talk time for ten hours of charging. A device that costs a year's salary and holds thirty phone numbers is not a bad product — it is the first product, and every constraint listed was solved within a decade.
