Nominal vs Real GDP Explained
Nominal GDP measures economic output using current prices, while Real GDP measures output using constant base-year prices to isolate actual production growth from price inflation. Real GDP allows economists to determine whether an economy is truly growing or just experiencing price increases.
Key Takeaways
- What is Nominal GDP? (Current Output × Current Prices)
- What is Real GDP? (Current Output × Base Year Prices)
- Why use Real GDP? (To measure actual production growth, not price inflation)
- How to calculate Real GDP? (Hold prices constant at base year levels)
