COSTVAC is an Excel-based toolkit that provides structured guidance on how to estimate the cost of routine immunization from a sample of health facilities and administrative levels of the health system. This toolkit provides guidance on sampling, survey instrument development and administration, and calculations.

It was developed to help countries more precisely document the shared resource use between the immunization program and other health service provision. Users can define the perspective and scope of the analysis.
