How to use this tool?
This calculator computes four key macroeconomic indicators from your inputs. All monetary values must be in billions of dollars, and population/unemployment/labor force in millions.
- Enter Data: Fill in all 11 fields (GDP, Population, Current CPI, Previous CPI, Unemployed, Labor Force, Consumption, Investment, Government Spending, Exports, Imports).
- Click "Calculate": The button validates that all entries are positive numbers. Invalid fields show a red border and error message.
- Read Results: Four metrics appear:
- GDP per Capita = GDP ÷ Population (in dollars)
- Inflation Rate = ((Current CPI − Previous CPI) ÷ Previous CPI) × 100 (as a percentage)
- Unemployment Rate = (Unemployed ÷ Labor Force) × 100 (as a percentage)
- GDP (Expenditure Approach) = Consumption + Investment + Government Spending + (Exports − Imports) (in billions of dollars)
- Interpret: Positive inflation means rising prices; a higher unemployment rate indicates more joblessness; GDP per capita shows economic output per person.
Tip: Ensure CPI values are from the same base year. The calculator uses the standard expenditure formula for GDP.

Frequently Asked Questions
GDP per capita is a measure of a country's economic output per person. It is calculated by dividing the total GDP by the population.
The inflation rate is calculated as the percentage change in the Consumer Price Index (CPI) from one period to another: ((Current CPI - Previous CPI) / Previous CPI) × 100.
The expenditure approach sums up consumption, investment, government spending, and net exports (exports minus imports). It represents total spending on goods and services in an economy.
