How to Assess Spending Needs of the Sustainable Development Goals: The Third Edition of the IMF SDG Costing Tool

This note provides a technical overview and description of the 3rd edition of the IMF SDG costing tool that estimates the additional spending needs to achieve a strong performance in selected SDGs for human capital development (health and education) and physical capital development (infrastructure), in particular, water and sanitation, electricity, and roads. The 3rd edition includes data and methodological updates to, but generally remains faithful to the original approach described in, Gaspar et al. (2019). Globally, additional spending needed to achieve a strong performance in the selected SDGs in 2030 amounts to US$3.0 trillion (3.4 percent of 2030 world GDP). Estimated at 16.1 percent of 2030 LIDC GDP, the average additional SDG cost of this income group is significantly higher than in EMEs, who face additional spending amounting to 4.8 percentage points of their GDP in 2030. In contrast to EMEs and LIDCs, the additional cost for AEs is low, under 0.2 percent of their 2030 GDP.
