It depends on the journal. I’ve only published in medical related journals, but some journals don’t charge a fee if the article remains closed access. Some journals just have an embargo period, so you may be free to republish to pubmed central or something similar after a year or two. Open access of course always costs money, or more if they do charge a publishing fee. A lot of nih grants have requirements to make it open access within a year, so some publishers at least are just embargoing for a year now.
