Macroeconomics involves the study of how the limited resources are utilized by a whole economy in production of goods and services for consumption. Economies can be those of state or even the world. The overall decisions concerning the economic factors affecting the whole economy are made. The economic factors affecting the state include the total national earning, the rate of employment, inflation and deflation rates and the total worth of the goods and services produced in the state among others.

The following are the differences between real and nominal calculations in macroeconomics:

1. Real calculations are based on the value of the goods and services while nominal calculations are based on the monetary value.

2. Real calculations are adjusted to accommodate the effect by the factors of inflation while nominal calculations are not adjusted.

3. The real value remain unchanged while the nominal value depends on the current price of the asset at the time of calculation.
