To calculate the value you personally received for each $1.00 in tax support we collected information on your community's 2010 population and library support  from Wisconsin's Public Library Statistics, compiled by the State Division for Libraries, and Technology (DLT).

The return on investment is calculated by first dividing your community's annual library appropriation by the community's population to calculate the annual "per-capita" expenditure - the amount spent per person for library support. Your monthly value received is multiplied by 12 to calculate the annual value you received from your library. Your annual value received is then divided by your community’s per-capita expenditure to get your annual value received per dollar of tax support.

This calculator is an adaptation of projects by the Maine State Library and Library Research Service, a unit of the Colorado State Library and the Colorado Department of Education that is operated in partnership with the Library and Information Science (LIS) Program, Morgridge College of Education, University of Denver.
