We can use the same formula to calculate both nominal and real GDP growth rates. The formula is: (GDP in year 2 / GDP in year 1) - 1. Let's say that in year 1, which is the base year, real GDP was $16,000.In year 2, real GDP was $16,400. Now we can calculate the growth rate in real GDP because we have two years of data. The growth rate is simply ($16,400 / $16,000) - 1 = 2.5%.e can use the same formula to calculate both nominal and real GDP growth rates. The formula is: (GDP in year 2 / GDP in year 1) - 1. Let's say that in year 1, which is the base year, real GDP was $16,000.
