What Is the GDP Growth Rate?
The GDP growth rate measures how much an economy’s total output has increased or decreased between two periods, typically quarter-over-quarter or year-over-year. It is one of the most widely watched indicators of economic health.
The Formula
GDP Growth Rate (%) = ((Current GDP − Previous GDP) ÷ Previous GDP) × 100.
A positive growth rate indicates economic expansion, while a negative rate indicates contraction. For precise comparisons over time, economists typically use real GDP (adjusted for inflation) rather than nominal GDP. This calculator is intended for general educational and planning purposes.
