International Journal of Molecular Sciences publishing costs and open access options
APC is one cost. Funder mandates, institutional agreements, and access route timing all shape what you actually pay.
What shapes what you pay
- Gold OA at International Journal of Molecular Sciences costs €2,000-2,500. Check whether your institution has a read-and-publish agreement that waives this.
- Funder mandates (NIH, Wellcome, UKRI) may require immediate OA — verify compliance before choosing a subscription route.
- Accepted authors typically have 48-72 hours to choose their access route before proofs begin.
When OA is worth the cost
- When your funder or institution requires it — non-compliance can affect future funding.
- When your topic benefits from broad immediate access beyond institutional subscribers.
- International Journal of Molecular Sciences's IF 4.9 means OA papers here have real citation upside.
Quick answer: International Journal of Molecular Sciences currently charges CHF 2,900 for accepted papers. IJMS is fully gold open access, so there is no free subscription route. Every accepted article pays the APC unless a waiver or discount applies. The real question is not whether the fee exists. It does. The real question is whether speed, indexing, and broad molecular-science discoverability are worth CHF 2,900 for this manuscript. For the hub, see the International Journal of Molecular Sciences journal page.

If the real question is whether the manuscript is good enough for IJMS before you commit to the fee, use an International Journal of Molecular Sciences submission readiness check. If the bigger risk is a speed-first submission with an unfinished evidence package, use an IJMS manuscript readiness check.
What MDPI currently says
The current MDPI APC information for IJMS is straightforward:
- all IJMS articles publish in full open access
- the APC is CHF 2,900
- the invoice is sent after acceptance
- MDPI accepts payment in multiple currencies
- local VAT or sales tax may be added
- discounts are available through the Institutional Open Access Program and affiliated societies
That is much cleaner than the older generic "about $3,000" language that many aggregator pages still use.
The more important planning point is that IJMS combines a fixed APC with a very high-volume editorial model. Authors are not just buying open access. They are buying a particular combination of scale, speed, and broad molecular-science discoverability.
What authors actually choose between
Route | What authors should assume |
|---|---|
Standard accepted paper | CHF 2,900 |
Paper with IOAP discount | Lower author bill |
Paper with lower-income-country support | Discounted or waived |
Invited or editor-handled edge cases | Sometimes reduced, but not the norm |
Free paywalled publication | Not available |
This is why the APC question at IJMS is simpler than at a hybrid journal. There is no paywall alternative to fall back on. If you submit, you are implicitly saying the gold-OA, fast-turnaround MDPI model works for the project.
Metrics context behind the APC
Metric | Current figure | Why it matters with the APC |
|---|---|---|
Impact Factor | 4.9 | Q1 status is real, even inside a scale-journal model |
5-year JIF | 5.7 | Longer-run citation profile is stronger than the 2-year window alone |
CiteScore | 9.0 | Scopus visibility is solid |
H5-index | 277 | Discoverability is real, though diluted by volume |
JCI | 0.71 | Field-normalized performance is weaker than the quartile label suggests |
Median first decision | 17.8 days | Speed is part of the product you are paying for |
Acceptance to publication | 2.6 days | Production is extremely fast after acceptance |
This is the core tradeoff. IJMS is not a scarcity journal. It is a fast, visible, indexed, broad-scope molecular-science journal. The APC is easiest to justify when those are exactly the properties you need.
Long-run impact factor trend
Year | Impact factor |
|---|---|
2017 | 3.7 |
2018 | 4.2 |
2019 | 4.6 |
2020 | 5.9 |
2021 | 6.2 |
2022 | 5.6 |
2023 | 5.1 |
2024 | 4.9 |
The directional move is negative. IJMS is down from 5.1 in 2023 to 4.9 in 2024 after the earlier MDPI-wide citation peak. That matters because the APC should be read as a payment for speed and open-access reach, not as a ticket into an increasingly selective prestige journal.

How IJMS compares with nearby broad-OA options
Journal | APC structure | Metric profile | Practical fit |
|---|---|---|---|
IJMS | CHF 2,900, fully OA | IF 4.9, CiteScore 9.0 | Broad molecular-science work where speed and indexing matter |
Lower APC, fully OA | Lower citation profile | Better when budget matters more than field-specific optics | |
Higher fully OA sticker price | Large broad-science platform | Better when Springer Nature agreement coverage helps | |
Slightly lower MDPI APC | Narrower chemistry-centered lane | Better if the paper is really chemistry rather than broader molecular science | |
eLife | Different post-review fee model | Distinct editorial culture | Better when the consultative-review model is the real attraction |
IJMS is attractive when the manuscript needs a broad molecular audience and quick handling. It is less attractive when the paper would gain more from a narrower specialist title or a stronger brand signal.
What we see in pre-submission review work with IJMS manuscripts
In our pre-submission review work, the APC itself is rarely the main problem.
Speed-first submissions still fail when the evidence package is unfinished. IJMS moves quickly, but reviewers still push hard on controls, completeness, and overclaiming.
The journal makes more sense as a scale-journal choice than as a prestige-journal choice. Authors who expect the APC to buy a scarcity signal are usually optimizing for the wrong thing.
The right decision sequence is venue, then fee. If the paper benefits from broad indexing, fast handling, and immediate OA, the CHF 2,900 is easier to defend. If the manuscript is career-critical and signal-heavy, the APC can feel expensive for what the journal actually is.
Submit if / Think twice if
Submit and accept the APC if:
- the work is technically sound molecular science and speed matters
- immediate OA is useful, not just a box to tick
- the budget can carry CHF 2,900 or an institutional discount reduces the pain
- the paper benefits from broad rather than highly selective specialist reach
Think twice if:
- the project is prestige-sensitive and brand signal matters more than speed
- the paper is really a narrower specialist story that deserves a tighter journal
- you are paying out of pocket and a cheaper broad-OA journal would serve the same purpose
- the manuscript is unfinished and you are relying on fast handling to compensate
Practical verdict
The IJMS APC answer is not ambiguous:
- CHF 2,900
- fully OA
- no free route
- speed and indexing are the main reasons to pay
That makes the decision unusually clean. If those four things match the manuscript strategy, the APC is defensible. If they do not, the price starts to look high for a scale-journal lane.
Frequently asked questions
International Journal of Molecular Sciences currently charges CHF 2,900 for papers accepted after peer review. IJMS is fully open access, so there is no free subscription route.
No. IJMS is a gold open-access MDPI journal, which means every accepted paper is published open access and requires the APC unless a waiver or discount applies.
Yes. MDPI says discounts are available through its Institutional Open Access Program and affiliated-society arrangements, and waiver or discount support is available for eligible lower-income-country authors.
The current journal-statistics signals around IJMS show about 17.8 days to first decision and 2.6 days from acceptance to publication, which is a major part of the journal's value proposition.
It is easiest to justify when speed, indexing, and broad molecular-science discoverability matter more than scarcity or brand prestige, and when the budget can absorb a CHF 2,900 gold-OA fee.
