The Dutch top the list with 89.2 percent. Poland comes last with 36.5 percent. Spain invests around 10.4 percent of its gross domestic product (GDP) in pensions. Italy only puts 9.8 percent of economic output into the pension system. In Denmark you only retire at 74 years old. Pensioners in Germany are left with around 53 percent of their last net income.
