User blog comment:Pihou/How Many VOCALOIDs Sold?/@comment-53539-20140617081943

I doubt its gone past a million. ¬_¬

If Miku's sales are any indication, being the most successful and with the best sales, then no other Vocaloid has surpassed 60,000.

At the same time, due to the number of sales for Miku, we can gather there can only roughly be about 60,000+ producers in the Vocaloid field. This isn't a true number, since not everyone has Miku, but most of those working in Japan have Miku.

Considering that the rate of successful business for Voclaoid is put at 1,000, and that a highly successful sales can be about 3,000 (Meiko V1), I'd put the overall successful Voclaoid sales between 6,000-8,000 on average. There are some that have done better and others that have done worst. Without other Vocaloid sales to go by, we haven't a foggest what the average is so this is a guess. But I'd put the number of total Vocaloid sales between 350,000-500,000 approx. :-/
