Real versus nominal value (economics)
In economics, real value is relative to other commodities or goods. It is adjusted for inflation, enabling comparison of quantities as if prices had not changed. Changes in real terms therefore exclude the effect of inflation. In contrast with real value, nominal value is not adjusted for inflation, and so increases in nominal value reflect the effect of inflation.
