GDP Calculator

Calculate Gross Domestic Product using the Expenditure, Income, or Production approach. Also compute Real GDP, GDP per Capita, GDP Growth Rate, and GDP Deflator.

$
Expenditure Approach

GDP = C + I + G + (X − M) where C = Consumption, I = Investment, G = Government Spending, X = Exports, M = Imports.

Expenditure Components
$
Household spending on goods & services (excl. new housing)
$
Business investment, new housing, change in inventories
$
Government purchases (excludes transfer payments)
$
Value of goods & services sold abroad
$
Value of goods & services bought from abroad
$
Auto-calculated from Exports minus Imports

∑
Income (Resource Cost) Approach

GNP = Employee Compensation + Proprietors' Income + Rental + Corporate Profits + Interest. Then GDP = GNP + Indirect Taxes + Depreciation + Net Income of Foreigners.

GNP Components
$
Wages, salaries & employer social contributions
$
Non-corporate business income (sole proprietors, partnerships)
$
Income from property ownership (excludes corporate real estate)
$
Corporate income (paid out or reinvested)
$
Income from deposits, debt securities, loans
GDP Adjustments
$
Sales taxes, property taxes, license fees
$
Capital consumption allowance
$
Domestic citizens' income abroad MINUS foreigners' income domestically (can be negative)

Real GDP & GDP Deflator

Real GDP adjusts for inflation using base-year prices. The GDP Deflator measures the price level of all domestically produced final goods and services.

GDP at current market prices
Base year = 100. Enter current year deflator index value

GDP Per Capita

GDP per capita = GDP ÷ Population. It measures average economic output per person and is used to compare living standards across countries.

GDP Growth Rate

GDP Growth Rate = ((Current GDP − Previous GDP) / Previous GDP) × 100. Measures how much an economy has grown or contracted over a period.

GDP in the earlier period (quarter/year)

GDP Guide & Reference
What is GDP?
Gross Domestic Product (GDP) is the monetary value of all final goods and services produced within a country's borders in a given period (usually quarterly or annually). It is the most widely used measure of economic size and health.
Three Approaches to Measuring GDP
1. Expenditure Approach: GDP = C + I + G + (X − M)
2. Income Approach: GDP = GNP + Indirect Taxes + Depreciation + Net Foreign Income
3. Production Approach: Sum of value added by all sectors

All three approaches produce the same result in theory.
Nominal vs Real GDP
Nominal GDP — valued at current market prices (affected by inflation)
Real GDP — adjusted for inflation using a base year (Real GDP = Nominal GDP / Deflator × 100)
GDP Deflator — (Nominal GDP / Real GDP) × 100

Real GDP is used to compare economic growth across years as it removes the effect of price changes.
GDP Growth Benchmarks
> 3% — Strong economic growth
2–3% — Healthy, stable growth
1–2% — Modest growth
0–1% — Stagnation
Negative (2 consecutive quarters) — Technical recession
