GDP Calculator
Calculate Gross Domestic Product using the expenditure approach: GDP = C + I + G + (X − M). Optionally compute GDP per capita, real GDP, and growth rate.
About the GDP Calculator
Gross Domestic Product (GDP) measures the total monetary value of all goods and services produced within a country in a given period. The expenditure approach — the most common — sums four components: Consumer spending (C), Business investment (I), Government spending (G), and Net Exports (X − M). If imports exceed exports, net exports are negative, reducing GDP. Real GDP adjusts for inflation using the GDP deflator: Real GDP = (Nominal GDP / Deflator) × 100. For inflation-related calculations, visit the Inflation Calculator.
GDP per capita divides total GDP by the population, providing a rough measure of average living standards. The growth rate compares current GDP to a prior period: Growth = (Current − Prior) / Prior × 100. A growth rate above 2% is generally considered healthy for developed economies; two consecutive quarters of negative growth define a recession. For personal budget and income analysis, use the Budget Calculator. For percentage computations on GDP components, the Percentage Calculator is a quick tool.
