Millionaire Register Statistics 2025

This page presents some basic statistics derived from the Register of Millionaire Calculators.

As of January 2025, the register contained details of 282 machines, or about 5.5% of the total production. 12 machines have been added in the past year.

Distribution by country.

"Unknown" in this chart refers only to location. The machines are known to exist from photographs and serial numbers in auction catalogues and elsewhere, but the current owners and locations are not known.

Distribution by serial number.

H.W.Egli used a single series of numbers for all of their production, but blocks of numbers were reserved for specific models at various times.

• Serial numbers 3501 to 4000 were assigned to "long Madas" machines, which entered production in 1913.
• Numbers 4501 to 6000 were also reserved for the long Madas.
• Numbers after 6501 were used primarily used for the Madas, with only occasional Millionaires.

Distribution by type.

The "Type" codes are made up from four fields:

• Number of columns: 4, 6, 8, 10, or 12
• Setting mechanism: Sliders or Keyboard
• Case: Wood or Metal
• Power: Hand crank or Electric motor
