After I begin receiving Social Security retirement, can my monthly benefit amount ever go down?
Once you begin receiving Social Security retirement, your monthly benefit amount will never go down. In fact, due to cost of living increases your benefit amount will always go up.
However, there are certain situations, which may reduce the amount you actually receive in your monthly Social Security check. For instance, if you are repaying an overpayment or have a garnishment the amount you receive in your monthly check will be reduced, although your Social Security benefit amount will not have changed.
