How long is the lifespan of U.S. paper money?
When currency is deposited with a Federal Reserve Bank, the quality of each note is evaluated by sophisticated processing equipment. Notes that meet our strict quality criteria--that is, that are still in good condition--continue to circulate, while those that do not are taken out of circulation and destroyed. This process determines the lifespan of a Federal Reserve note.
The lifespan of Federal Reserve notes varies by denomination and depends on a number of factors, including how the denomination is used by the public. For example, larger denominations such as $100 notes are often used as a store of value, which means they pass between users less frequently than lower-denominations such as $5 notes, which are more often used for transactions.
*Estimated lifespans as of December 2018. Because the $2 note does not widely circulate, we do not publish its estimated lifespan.
