Individual Return on Investment Calculator

The Return on Investment (ROI) Calculator determines the value of library services in Rhode Island communities based on per capita spending of local and state funding.

Please enter the number of times you use the following library services each month:

Your Use Library Services Value of Services
Value you receive monthly from your library: $
For every $1.00 in taxes you spend on public libraries in your library, you receive $ of value in return*
       

Where did these numbers come from?

Typical taxpayer contributions are determined from the library's 2007 local income per capita, which includes the local appropriation and state grant-in-aid. For Rhode Island libraries, this information is available on the chart of tax dollars expended on public libraries. The figures for the value of library service are from the Maine State Library's Library Use Value Calculator. For more information, see their explanation. The calculator was developed by the Library Research Service of the Colorado State Library and used by permission.

*Your personal return on investment is based on your responses and the average annual tax contribution for the West Warwick Public Library. You see a returned value of $ for every one dollar invested. View data on tax dollars expended on RI public libraries.
