Three GDP approaches
Expenditure (this one, C+I+G+NX), Income (compensation + profits + taxes), and Production (sum of value added). All three theoretically give the same number.

Nominal uses current prices. Real adjusts for inflation by using a base year\u2019s prices. For comparing GDP across years, always use real.
GDP limitations
