Real GDP Growth Rate
Quarterly percent change in real gross domestic product, seasonally adjusted annual rate
Real GDP measures the total value of goods and services produced in the United States, adjusted for inflation. The growth rate shows the percentage change from the previous quarter, expressed as an annualized rate. This key economic indicator helps assess the health of the U.S. economy and is closely watched by traders, analysts, and policymakers.

How GDP Growth Rate is Calculated
Calculation Method
The Bureau of Economic Analysis (BEA) calculates the quarterly GDP growth rate as an annualized rate using a two-step process:
This annualization assumes the same growth rate continues for four consecutive quarters. The figures are seasonally adjusted to remove recurring patterns.
Methodology Changes Over Time
GDP growth rate measurement has evolved as the BEA improved its methodology to capture economic activity more accurately:
- 1996 - Chain-Weighted Indexes: The BEA switched from fixed-weight methodology to chain-type Fisher indexes. This allows for changing relative prices over time, producing more accurate long-term growth comparisons.
- 2013 - R&D Capitalization: Research and development expenditures began being treated as fixed investment rather than intermediate consumption, aligning with international standards.
- 2015-2018 - Seasonal Adjustments: The BEA implemented improvements to reduce "residual seasonality" - systematic patterns that persisted in seasonally-adjusted data, particularly the tendency for Q1 growth to appear weaker.
Understanding Revisions
GDP growth rates are subject to revisions as more complete data becomes available. Annual revisions occur each summer, and comprehensive revisions every five years can adjust the entire historical series back to 1929.

FISES Usage
Real GDP Growth has a weight of 2.3 in the FISES formula, making it the most influential indicator. Higher GDP growth increases the overall score.
Release Schedule
GDP is released quarterly by the Bureau of Economic Analysis (BEA), approximately one month after each quarter ends, with two subsequent revisions.
- Advance estimate (1 month after quarter)
- Second estimate (2 months after quarter)
- Third estimate (3 months after quarter)
