This document summarizes costing efforts related to violence against women and girls (VAW/G) in several Asian and Pacific countries. It describes initiatives in India, Vietnam, Cambodia, and Pacific Island nations to calculate the economic costs of VAW/G. The studies used methods like impact costing, unit costing, and gender-responsive budgeting. While challenges exist, the costing exercises helped advocate for more resources to address VAW/G by highlighting funding gaps. Lessons indicated using multiple methods and recognizing limitations, but that any costing provides useful evidence for policymaking.
