Hi Marilyn,
I cannot give you a magic number, but I can tell you what our numbers are like. With journals, cost per download is actually a pretty good measure, so I get good numbers from our journal packages. I use annual usage against subscription price and find that my JSTOR and Project Muse packages are around $1 per download. Other similar packages run as high as $5. My social science journals run up to $10, and only my STM journals exceed $10. I know a colleague who sets $20 as the maximum for her renewals.
With databases, the only consistent measure I can get for all of them is searches, so I compute cost per search, but the figures come out all crazy amounts, so I don't report them out, but I do look at them, and the ones I believe to be well-used and economically priced do tend to come out under 30 cents per search.
Your figures may be totally different, of course.
Good luck,
Judith

Subject: [SERIALST] Database return on investment
I'm hoping other continuing resources people can help me answer this
question: What is a good return on investment? Or what's a "good" cost
per use?
I'm not asking how to get these numbers; rather I'm wondering what these
numbers mean once you have them. I recognize that there are a dozen
reasons for paying for some databases no matter what the cost per use
is. And I recognize that cost per use doesn't necessarily mean that a
database was used "well". I also recognize that "use" can have a
variety of meanings.
But right now, I need to be able to say simply how much certain
databases cost per each use and whether that's a good indicator or a bad
one. Does anyone have that magic (possibly meaningless!) number?
Thanks,
Marilyn Geller
