A U.S. savings bond is a nonmarketable Treasury security for retail savers, with interest, redemption, and tax rules set by Treasury.
A savings bond is a nonmarketable U.S. Treasury security issued for retail savers. Unlike a marketable Treasury note or bond, a savings bond is not traded in the secondary market; the owner generally buys, holds, values, and redeems it under TreasuryDirect rules.

A family finds paper savings bonds in a safe deposit box. The first useful step is not estimating a market yield; it is identifying the series, issue date, denomination, owner, and whether the bond still earns interest. Treasury’s paper savings bond calculator or TreasuryDirect account records are the source to verify value and maturity status.
