The projected gross pension replacement rate, which compares retirement benefits to pre-retirement earnings, varies significantly across countries. This rate estimates how much of an average earner's previous income a pension will cover before taxes and contributions. Southern European nations, like Spain and Greece, lead the rankings with replacement rates exceeding 79%. Countries such as Luxembourg, Colombia, and the Netherlands also offer substantial pension replacement percentages. Conversely, some wealthier nations have lower replacement rates; Germany provides 42.1% and the U.S. offers 39.7%. At the bottom of the list, Lithuania's replacement rate is a mere 17.4%, with South Korea and Japan also ranking low. National prosperity does not directly correlate with these pension replacement figures, as illustrated by Mexico and Türkiye's relatively high rates. Low replacement rates don't always equate to high senior poverty, but a correlation exists for some countries. For example, Lithuania, Estonia, and Latvia face elevated old-age poverty rates alongside their low pension replacements. The Netherlands, however, maintains a high replacement rate with a low poverty rate for seniors. These figures highlight the diverse structures and outcomes of pension systems globally.
