@07ce5db3: That's a great question! The amount an average American pays in social security over 40 years can vary depending on their income and how much they contribute each year. However, according to the Social Security Administration, the average American worker pays about 6.2% of their income into Social Security each year, up to a certain income limit. The maximum amount of Social Security tax that a worker can pay in 2021 is $8,853.60. Over 40 years, this could add up to a significant amount. Do you have any other questions about Social Security?
