GDP Calculator

Consumption (C)

Enter values in the same currency/units (e.g., dollars). Commas/spaces allowed.

Investment (I)

Government (G)

Exports (X)

Imports (M)

GDP Deflator (index, base=100)

Used to convert Nominal GDP → Real GDP. Leave blank to skip real GDP.

Population (persons)

Previous Period GDP (nominal)

For growth rate vs. last period. Use the same currency/units as above.

Pick CSV

Drag & drop a CSV here (columns: C,I,G,X,M,Deflator,Population,PrevGDP)

All inputs are treated as numbers. Use the same currency/units across components (e.g., dollars). Commas and spaces in inputs are ignored.

GDP Calculator – Quick Cheat Sheet

Nominal GDP = C (Consumption) + I (Investment) + G (Government) + (X − M) (Net Exports).
Real GDP adjusts for price changes using a GDP Deflator (index, base=100): Real = Nominal / (Deflator / 100).
GDP per Capita = GDP ÷ Population (both nominal and real versions are useful).
Growth Rate vs. previous period = ((Current − Previous) / Previous) × 100%.
Units: Use the same currency/units for every component. If you enter billions, keep everything in billions.
Sign convention: Imports (M) are subtracted; negative net exports reduce GDP.

Edge cases & notes

Deflator must be > 0 to compute Real GDP. Leave blank to skip.
Population must be > 0 to compute per-capita values.
Previous GDP must be non-zero to compute a growth rate.
