An article processing charge (APC), also known as a publication fee, is a fee which is sometimes charged to authors to make a work available open access in either an open access journal or hybrid journal.^[1][2][3] This fee is usually paid by an author's institution or research funder rather than by the author themselves.^[4] Some publishers waive the fee in cases of hardship.^[5] An article processing charge does not guarantee that the author retains copyright to the work, or that it will be made available under a Creative Commons license.^{[citation needed]}

Journals use a variety of ways to generate the income required to cover publishing costs (including editorial costs, any costs of administering the peer review system), such as subsidies from institutions^[6] and subscriptions. A majority of open access journals do not charge article processing charges,^[7] but a significant and growing number of them do.^[8] They are the most common funding method for professionally published open access articles.^[9]

APC fees applied to academic research are usually expensive, effectively limiting open access circulation among the less affluent institutions, scholars, and students.

APC model of open access, among other controversies — is part of the wider and increasing global Open Access OA's ethics debate.^[10]

Different academic publishers have widely varying levels of fees, from under $100 to over $3000.^[1][11][12] High fees are sometimes charged by traditional publishers in order to publish in a hybrid open access journal, which make an individual article in a subscription journal open access. The average APC for hybrid journals has been calculated to be almost twice as high as APCs from full open access publishers.^[13] Journals with high impact factors from major publishers tend to have the highest APCs.^[1] Many open access publishers, such as PLOS, waive their APCs for those who cannot afford to pay them.^[5]

Open access articles often have a surcharge compared to a closed-access APC; for example the Proceedings of the National Academy of Sciences regularly charges $1700 per article, with a surcharge of $1350 for open-access.^[14] Similarly, AGU's Journal of Geophysical Research charges $1000 for closed-access and $3500 for open-access.^[15]

Even when publishers do not charge standard fees, excess or overlength fees might still apply after a certain number of pages or publication units is exceeded;^[15][16] additional fees might exist for color figures,^[14] primarily for print journals that are not online-only.

While publication charges occur upon article acceptance, article submission fees are charged prior to the start of peer review; they are not uncommon among journals in some fields, e.g., finance and economics.^[17]Page charge may refer to either publication or submission fees.

Criticism

The "article processing charges" which are often used for open access journals shift the burden of payment from readers to authors (or their funders), which creates a new set of concerns.^[18] One concern is that if a publisher makes a profit from accepting papers, it has an incentive to accept anything submitted, rather than selecting and rejecting articles based on quality. This could be remedied, however, by charging for the peer-review rather than acceptance.^[19] Another concern is that institutional budgets may need to be adjusted in order to provide funding for the article processing charges required to publish in many open access journals (e.g. those published by BioMed Central^[20]). It has been argued that this may reduce the ability to publish research results due to lack of sufficient funds, leading to some research not becoming a part of the public record.^[21]

Unless discounts are available to authors from countries with low incomes or external funding is provided to cover the cost, article processing charges could exclude authors from developing countries or less well-funded research fields from publishing in open access journals. However, under the traditional model, the prohibitive costs of some non-open access journal subscriptions already place a heavy burden on the research community; and if green open access self-archiving eventually makes subscriptions unsustainable, the cancelled subscription savings can pay the gold open access publishing costs without the need to divert extra money from research.^[22] Moreover, many open access publishers offer discounts or publishing fee waivers to authors from developing countries or those suffering financial hardship. Self-archiving of non-open access publications provides a low cost alternative model.^[23]

Another concern is the redirection of money by major funding agencies such as the National Institutes of Health and the Wellcome Trust from the direct support of research to the support of open access publication. Robert Terry, Senior Policy Advisor at the Wellcome Trust, has said that he feels that 1–2% of their research budget will change from the creation of knowledge to the dissemination of knowledge.^[24]

Research institutions could cover the cost of open access by converting to an open access journal cost-recovery model, with the institutions' annual tool access subscription savings being available to cover annual open access publication costs.^[25] A 2017 study by the Max Planck Society the annual turnovers of academic publishers amount to approximately EUR 7.6 billion. It is argued that this money comes predominantly from publicly funded scientific libraries as they purchase subscriptions or licenses in order to provide access to scientific journals for their members. The study was presented by the Max Planck Digital Library and found that subscription budgets would be sufficient to fund the open access publication charges.^[26]
