Title: Sales figures
Post by: Misel982001 on 23:31, 11 September 17
Hello guys! I hope you are well!  I did a research on my own but I could not find how many CPC's were sold, overal and per range. How many 464's, 664's, 6128's and plus range were totally sold over the years?
Besides this, what was the biggest selling game of the cpc and how many copies of it were sold?
Thanx!

You could try using the German Tank Problem method to estimate how many CPCs were sold?

Although the german tank problem analysis seems more than right here, I think that I would go for a more simplistic view. Knowing Amstrad, I am quite sure that they managed to sell all the units of the standard CPC, and probably quite a few of the Pluses, if not all. If we knew the production numbers we would probably know the units sold as well. I reckon that they did not scrap a single machine  :) .


But we can always collect a ton of serial numbers and do our own analysis, it sounds fun!

Yes, but we DON'T know the production numbers, hence the need to use something like the German Tank method.

Maybe we can ask for the info?  :) I guess that it is not classified anymore. Otherwise yes, we can start collecting serial numbers  :D

Thankfully Amstrad changed pcb and their logo over time, so perhaps only use the serials of later cpc models. :)

From Google Images I found a Korean-manufactured 464 (http://bilgisayarlarim.com/Amstrad/CPC464/CPC464_17.jpg) with serial number 533-8301061, all on on line, and another (https://picclick.co.uk/Vintage-AMSTRAD-CPC-464-Colour-Personal-Computer-64K-292242741388.html#&gid=1&pid=12) with a much more flimsily stuck-on number of 55169 and/or K31-46.

Is enough known to determine how those two things relate to one another? If not then total production estimation could be tricky.

Nope... to apply the algorithm Bryce is suggesting you need several serial numbers and then work out, more or less, how the numbering worked. In principle the number could even come from individual parts, for example, the ASICs. These parts would need to be only present in the CPC or Plus range, an ubiquitous component would not be good for the purpose. It is even possible that we would need to tackle the problem by analyzing the numbers of each PCB version  :)

It's difficult to estimate sales numbers for every model, but the Amstrad website give us a good start:

3 Million CPCs
8 Million PCWs
12 Million PCs

Sadly, they don't list the Plus series, the 664 or the 472, so we must assume that either they sold marginally or that their numbers are included in the CPC range. Who knows.

You can use the dates on the ICs to tell when a CPC with serial number X was actually manufactured.

What we do know is that Amstrad made 70,000 664's. (source: The Amstrad Story) and that the total figure is somewhere near 3 million.


As a publicly listed company, Amstrad's Annual Report might yield info. Anyone ever looked?

I really dont get how to use the Tank Problem....

Wow that is alot of revenue 3 million CPC say at £400 thats £1.2Bn in revenue, 8 million PCW at £500 is £4Bn in revenue a huge amount of money in the 80s.  No wonder Alan is so well off!  Wonder what sort of margin they made on each unit?

Anyway sorry to butt in maybe someone could contact Amstrad and ask if they still have records, I know they owned by Sky now but you never know.
