Personal health spending grew at an average annual rate of 5.9% between 1996 and 2013, while gross domestic product (GDP) grew by 4.3%. The difference between these two rates is commonly referred to as the 'excess growth rate.' In dollar terms, excess growth was $472 billion, in the sense that if health spending had grown at the same rate as the GDP between 1996 and 2013, health spending would have been $472 billion lower in 2013 than it actually was.
