The Performance Improvement Calculator is an interactive tool that allows communities to use local cost and performance data on homeless programs to model strategies that decrease homelessness. It uses program budget information and key data from Homeless Management Information Systems (HMIS) to determine the cost per permanent housing outcome for different interventions within your community, such as emergency shelter, transitional housing, rapid re-housing, and permanent supportive housing interventions. If you have completed the Homeless System Evaluator Tool, you can use the data in that tool to populate the Calculator.
