Open access means everyone can read the article for free — for the reader. But that access has a cost, and it is usually passed to the author as an APC (article processing charge). Factoring the APC in early when you choose a journal protects your budget and keeps you clear of the hidden-fee traps of predatory journals. Here are the models and the costs.
Open access models — and who pays?
| Model | Access | Who pays? | Typical cost |
|---|---|---|---|
| Gold OA | Open in the journal | Author (APC) | A few hundred – $11,000+ |
| Green OA | Archived version in a repository | No one (author archives) | Free |
| Diamond/Platinum OA | Open in the journal | Institution/society funds it | Free to the author |
| Hybrid | Open per article | Subscription + author APC | Usually high |
| Subscription (closed) | Subscribers only | Reader/institution | No APC for the author |

How much does an APC cost?
APCs vary dramatically from journal to journal: a few hundred dollars at some regional or younger journals, $3,000–$11,000+ at the most prestigious international ones. For a reference point: across the DOAJ-registered open-access journals in Peerfect's 13,524-journal corpus, the median APC is USD 1,990 and more than half (52%) charge no APC at all (Academic Publishing Landscape 2026 data). Still, the key is to learn the figure from the journal's own official page. When budgeting, watch for:
- Currency and budget: APCs are usually in USD/EUR; exchange-rate swings affect your budget.
- Discounts and waivers: many journals offer APC discounts/waivers for low-income countries or specific institutions.
- Institutional deals: if your university has a "read & publish" agreement with the publisher, the APC may be covered.
Hidden costs and red flags
Legitimate open-access journals state the APC clearly before submission. These are warning signs:
- The APC arriving as a surprise with the acceptance letter.
- The fee being negotiable.
- Vague extra charges per page, per figure, etc.
- No APC information at all on the official page.
These are often predatory-journal tactics; use the predatory-journal checklist alongside your APC assessment.
Building cost into the decision
The APC is only one dimension of journal choice; weigh it together with scope fit, indexing and quartile. When choosing the right journal, ask from the start: "Open access or subscription, and what's my budget?" Peerfect's free journal recommendation engine lets you see access type and cost information while it suggests journals that fit your scope — so you choose both the right door and an affordable path.
