Two-Variable Cost Allocation Calculator

The Two-Variable Cost Allocator Calculator determines allocated costs and performance measures for transit services sorted by travel mode, jurisdiction, service type and individual route/service and by sponsor (if applicable).  The data can be used for National Transit Database (NTD) reporting, managing federal and state grants, and pricing and planning new services. 
The Two-Variable Cost Allocation Calculator is available in an MS Excel or MS Access application.  Both versions provide the same level of specificity for data inputs and produce output reports for individual routes/services or groups of routes.  You do not need Access installed to run the Access version.
