14. Will the APC rate I am given at submission change?
No. The APC payable for an article is determined at the time payment has to be agreed as part of the submission process. This means:
- If the APC goes up between submission and publication, you still pay the lower APC.
- If the exchange rates change between submission and publication, an author still pays the amount in their applicable currency that they agreed to pay on submission.
- If an institution ceases to be a Member between submission and publication of an author’s article, they still receive Membership benefits. Conversely, if an institution becomes a member after the author submits an article, that article will not in general be covered by the Membership.
