This is an estimation that Peter Suber gave in October 2013
(http://www.theguardian.com/higher-education-network/blog/2013/oct/21/open-access-myths-peter-suber-harvard):
"about 50% of the articles published by peer-reviewed OA journals overall
were published in fee-based OA journals". I think it was based on the SOAP
study.

Objet : [GOAL] Re: Two-thirds of DOAJ journals do not have article processing
charges
Heather,
these are useful data, but in the interpretation of these we will have to
reckon with journal size distributions. What would be helpful is having data on
the number of articles in these journals. It is very likely that smaller
journals are overrepresented in the non-APC OA group and that the share of non
APC OA output by number of articles is substantially lower than 64%. Maybe 50
percent or even 40? I do not like guessing, so I hope someone will look into
this and come up with some data based on article counts.
Best,
Jeroen

Subject: [GOAL] Two-thirds of DOAJ journals do not have article processing
charges
Thanks to a file supplied by DOAJ community manager Dominic Mitchell, we can
confirm that 64% or about two-thirds of the journals added to DOAJ since March
2014 do not have article processing charges (720 No charges, 403 Yes charges,
total 1,123). Although there may be differences between this sub-sample and
journals entered in DOAJ before March 2014, this ratio is similar to what we
reported earlier and others have been reporting for some time.
The text file supplied by DOAJ has been added to the OA APC dataverse:
http://dataverse.scholarsportal.info/dvn/dv/oaapc
If anyone would like to transform the text file into .csv or other
spreadsheet-manipulable file, that would be helpful. For example, this kind of
processing would make it possible to provide a much more human readable title
list.
A bit more detail here:
