The G20 is an international forum for the governments and central bank governors of 19 countries and the European Union (EU). The group consists of the world’s largest and fastest-growing economies. Measuring a national economy through one factor alone could be misleading. Therefore, the aim of this study was to assess and evaluate the national economy of the Kingdom of Saudi Arabia (KSA) using multiple factors to compare the current economic situation with the future situation using Saudi Vision 2030 targets. A model was established using several input and output criteria to calculate economic efficiency. The model used data envelopment analysis (DEA) to measure efficiency, and the technique for preference by similarity to the ideal solution (TOSIS) was used to sort the economies of the G20 countries. The results reveal the economic efficiency of the G20 countries and facilitate sorting their economies based on several economic parameters.
