How Much Do Countries Spend? Education remains one of the biggest long-term investments governments can make, influencing skills, employment, productivity and social mobility. Across leading global economies, education spending generally falls between 4% and 6% of GDP. The OECD national average is around 4.7% to 4.9%, although spending varies significantly between countries. These differences reflect economic capacity, population size, government priorities and the importance each nation places on education in its development strategy.
