Q:

What is the difference between real money & nominal money?

Answer

Nominal money relates more to it's measure of counting - so nominal figure of what is written on bill, while "real" relates more to it's purchasing power (usually between some periods of time). For instance 100 units in nominal could buy 2 units of good in 1950 and 1 unit of good in 2005, at the same time real value of this 100 nominal units are 100 real units in 1950 and 50 real units in 2005.


Same is with GDP. In nominal it can rise due to inflation while it can stay the same or even decrease in real value.
