Article publication charge

An article publication charge (APC) is a fee levied by a publisher on an author, or on their funder or institution on the author’s behalf, to publish an article — most commonly, though not exclusively, to fund open-access (gold OA) publication under an open license such as CC BY. Publishers may separately levy other charges that are not the APC itself, including page charges, submission charges, colour-figure charges, charges for reprints, cover-image charges, supplemental-data publication fees, and third-party copyright charges; most of these other charges are not tied, directly or indirectly, to whether the article is published open access, and a publisher may levy both an APC and one or more of these separate fees on the same article.

What it is not

An APC is distinct from a subscription fee, which a library or institution pays for reading access rather than an author paying for publication, and from a transformative “Read and Publish” agreement, which bundles subscription reading access with reduced or waived APCs for eligible authors under a single institutional or consortial contract. It is also not the same guarantee as free to read status — an article can be free to read without an APC having been paid (e.g., under green open access or a subscription-funded hybrid arrangement), and in principle an APC-funded article could in theory still be published without full open licensing, though in practice most APC-funded articles are released under an open license.

An APC is also not a marker of vanity publishing. In a reputable journal the charge pays for production and dissemination behind a real editorial process — peer review and quality control precede acceptance, and paying does not buy publication. That is precisely what separates a legitimate gold-OA charge from a predatory journal, where the fee is effectively the only gate. Equally, charging an APC is not universal among open-access journals: many OA and hybrid titles levy no author-facing charge at all, covering their costs through institutional subsidy, learned-society sponsorship or consortial funding — the model usually described as diamond open access.

Current policy trends

Several major research funders have moved away from funding APCs directly in recent policy revisions, instead prioritising no-fee green open-access routes or negotiating specific no-APC publishing arrangements with individual publishers, reflecting a broader funder concern about the sustainability and equity of APC-funded gold open access, particularly for authors without institutional or funder support to cover the charge. Waiver and discount programmes exist at many publishers for authors from lower-income countries or without funding, though eligibility and scope vary by publisher.

In practice

A research office assessing publication costs should check the specific fee structure named in a journal’s author guidelines rather than assuming “APC” covers every charge that will appear on an invoice — page charges and other add-on fees can apply on top of, or independently of, the APC itself.
