Something that accrues; advantage accruing
"The new tax policy will allow small businesses to accrue significant advantages by reducing their overhead costs immediately."
To increase, to rise
"As interest rates rose over the year, her savings began to accrue at a faster pace than she had anticipated."
The word accrued first appeared in the mid-15th century, entering English via Old French. It ultimately derives from the Latin accrēsco, which means "to increase."
