The exchequer is the national treasury that holds public money. The public exchequer, a cost to the exchequer, Chancellor of the Exchequer.
The name is a chessboard, since medieval accounts were reckoned with counters on a chequered cloth, and the Chancellor of the Exchequer still carries the title. Any cost to the exchequer is a cost to the taxpayer.
