Frontiers in Microbiology APC and Open Access: What CHF 2,950 Buys in a Gold OA Megajournal

Frontiers in Microbiology is entirely gold open access. Like all Frontiers journals, there's no option to publish behind a paywall. Every article goes out under a CC BY license immediately upon publication.

This means:

• You can't avoid the APC by choosing a subscription route
• Every paper is free to read from day one
• The CC BY license allows reuse, redistribution, and derivative works with attribution

For researchers who need to satisfy funder OA mandates, this simplifies things. There's no license selection step. CC BY is the default and only option, which is exactly what Plan S, UKRI, and most European funders require.

Frontiers operates an Institutional Membership program that works differently from the Read & Publish deals you'll find at Springer Nature or Elsevier:

Frontiers Institutional Memberships:

• Member institutions receive 5-15% discounts on APCs
• The discount applies automatically when the corresponding author's institutional email matches a partner institution
• The institution pays an annual membership fee to participate
• Over 100 institutions participate worldwide

Consortium arrangements:

• UK institutions through Jisc have a Frontiers agreement
• Scandinavian consortia and Dutch institutions have negotiated discounts
• Some US universities participate, though coverage is less uniform than in Europe

The key difference from Springer Nature or Wiley: Frontiers institutional memberships reduce the APC by a percentage. They don't cover it entirely. Your grant or department still pays 85-95% of the fee. If you're used to Springer's Read & Publish deals that cover the full APC, the Frontiers model will feel less generous.

Automatic waivers: Corresponding authors in low-income countries (per World Bank classification) receive full APC waivers. The system recognizes eligible countries during submission.

Partial discounts: Authors from lower-middle-income countries get reduced rates, though the exact percentage isn't published and may vary.

Hardship waivers: Frontiers accepts requests from authors who can't access grant or institutional funding. Anecdotally, approval rates are lower than at publishers like AAAS or Springer Nature. If you're at a well-funded Western university, don't count on a hardship waiver being approved.

Funder-specific arrangements: Some funding bodies have direct agreements with Frontiers. Check with your grants office before assuming you need to pay out of pocket.

Because Frontiers in Microbiology is fully gold OA with CC BY as the only license, it satisfies every major open access mandate without any additional steps. There's no embargo period, no green OA workaround needed, and no license selection to worry about.

1. Over 5,000 articles per year. Frontiers in Microbiology is one of the highest-volume microbiology journals in existence. Only PLOS ONE publishes more microbiology content, and PLOS ONE is a multidisciplinary journal. This volume means the acceptance rate is relatively generous (estimated at 40-50%), but it also means the journal covers an enormous range of subfields, from food microbiology to virology to soil ecology.

2. The impact factor is 4.2 (2024). This places it in Q1/Q2 depending on the specific microbiology subcategory in JCR. It's lower than Applied and Environmental Microbiology (4.4) and well below mBio (6.4) or Nature Microbiology (20.5). But for the price point and the acceptance timeline, it's a fair tradeoff for solid work that doesn't need a prestige-tier venue.

3. Section-based editorial structure. Frontiers in Microbiology has 18+ specialty sections, including Antimicrobials, Resistance and Chemotherapy; Evolutionary and Genomic Microbiology; Food Microbiology; Infectious Agents and Disease; Microbe and Virus Interactions with Plants; and Systems Microbiology. Your manuscript is assigned to the relevant section, so handling editors and reviewers should have genuine expertise in your area.

Frontiers has a distinctive peer review process that you should understand before submitting:

Interactive review: Authors and reviewers communicate directly through the Frontiers review forum. This can accelerate the revision cycle but also means the process isn't blind. Reviewer names are published with accepted articles.

Low desk rejection rate: Frontiers is designed to evaluate technical soundness rather than perceived impact. Most submissions that meet basic formatting and scope requirements proceed to review. This is the opposite of ASM journals, where editors desk-reject a significant fraction before review.

Speed: Frontiers typically has faster turnaround than ASM or Springer Nature journals. Median time from submission to acceptance is often 10-14 weeks, compared to 16-24 weeks at more selective venues.

Volume concerns: Some microbiologists view Frontiers' high volume with skepticism, arguing that quality varies too much across 5,000+ articles per year. Others counter that volume reflects broad subdiscipline coverage, not lower standards. Both perspectives have merit. The safest approach is to evaluate each paper on its own rather than generalizing.

• No page charges beyond the APC
• No color figure fees
• Currency risk: Because the APC is priced in CHF, the dollar equivalent fluctuates. If the Swiss Franc strengthens between submission and acceptance, you pay more in your local currency.
• VAT: European authors may owe VAT on top of the listed APC
• Formatting time: Frontiers has strict formatting templates. Manuscripts that don't conform are returned before entering review. This isn't a financial cost, but it's a meaningful time cost.

The journal is a good fit when:

1. Your work is technically sound microbiology that doesn't need a high-selectivity venue
2. You need or prefer gold open access with CC BY licensing
3. Your budget can handle ~$3,200 but not $6,000-$10,000
4. Speed matters and you want to avoid long review queues
5. You're early-career and need indexed, Q1/Q2 publications on your CV

Think twice if:

1. You're comparing against AEM's free subscription track and don't have an OA mandate
2. Your work is strong enough for mBio or ISME Journal, where the prestige-per-dollar ratio is better
3. Budget is very tight and PLOS ONE at $1,695 would also fit your scope
4. You or your advisors have concerns about the Frontiers brand perception in your subfield

Before submitting, check that your manuscript meets Frontiers' formatting requirements and that your methodology section is airtight. Even at journals with broad acceptance, reviewers focus on technical rigor. Run a free readiness scan to catch statistical gaps, missing controls, and structural issues that slow down review.
