Hi Ruth:
This is a great question. In general, museums are terrible at accounting for the cost of collecting and collections maintenance. There are a number of factors you might want to include such as - operating cost for the square footage of your storage and exhibition areas, staff cost, insurance, supplies, your Collection Management System and its annual maintenance, development and maintenance for any portion of your website that makes collections available. separating out the cost of exhibitions using collections and collections care may be something to think about in this calculation. Are preparators, for example, a programming cost or a collections care cost? If the exhibition content was not part of the collection, would we just hire any old person to hammer a nail in the wall?
The most recent (and it is OLD) study that focuses directly on the cost of collecting (except for the NEMA publication recently mentioned that i have not yet read) is Lord, Lord, and Nicks (1989) The Cost of Collecting - which was an extensive study of the cost of collecting in museums in the United Kingdom.
My dissertation (so close to being published - with copy editor now) tangentially examines this question. What I can tell you is that museums more focused on collections (care, maintenance, insurance, exhibitions, storage, staffing, etc) are less flexible, and less public-oriented. However, if you peruse the (also very old at this point) Heritage Health Index
Heritage Health Index - Full Report you will learn that LOTS of museums expend inadequate resources for collections care. This is a cautionary tale about bench-marking - comparing your museum to other museums will get you a general idea of how you stack up in this area, but you may be comparing rotten oranges to rotten oranges.
If you wanted, you might consider asking this question of DataArts
https://culturaldata.org/- they collect information about cultural organizations. I used some of their data for my dissertation project. I don't think the answer would be free, and I'm not sure you'd even be able to tell us what you found, depending on their proprietary restrictions, but boy, this is a question we really need an answer to!

Subject: Benchmarking Collections budget as a proportion to museum's total budget
I am trying to get a sense of the appropriate proportion of the total budget our history museum should budget for collections (supplies, care, storage and staffing). Our budget is $2.4 million in total. If anyone from a history museum or historic site would be willing to share your percentage, I sure would appreciate it. I know we are lower than we should be and are trying to work toward a benchmark. Ruth Haus
