bigger bang for the buck

More for one’s money. The term was invented in 1954 by U.S. defense secretary Charles E. Wilson, who was advocating bet- ter use of defense appropriations, relying principally on nuclear deterrents; “bang” refers to a nuclear explosion. Later it was extended to numerous civil- ian contexts calling for better value. It echoes an older advertising slogan for a soft drink, “More bounce to the ounce.”
