ROI Calculator (RI public libraries)
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. For municipalities with more than one independent
library, it determines the ROI for all libraries in that
community. Learn more about how the calculator works.
Please enter the number of times you use the following library services each month:
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 your library.
You see a returned value of $ for every one dollar invested. View data on tax
dollars expended on RI public libraries.
